Sandbox

Create and control a microVM sandbox: boot it from an image, run commands, stream logs and metrics, then shut it down. See Overview for configuration examples and Lifecycle for state management. For local runtime installation and verification, see Runtime setup.

Sandbox::builder()

fn builder(name: impl Into<String>) -> SandboxBuilder

Example

let sb = Sandbox::builder("api")
    .image("python")
    .create()
    .await?;

Create a builder for configuring a new sandbox. The builder lets you set the image, resources, volumes, networking, secrets, and other options before booting the VM. Sandbox names must be non-empty and no longer than 128 UTF-8 bytes. See SandboxBuilder for all available options.

Parameters

nameimpl Into<String>

Sandbox name - must be unique and no longer than 128 UTF-8 bytes.

Returns

SandboxBuilder

Builder for configuring the sandbox.

Sandbox::get()

async fn get(name: &str) -> MicrosandboxResult<SandboxHandle>

Example

let handle = Sandbox::get("api").await?;
println!("{:?}", handle.status());

Get a handle to an existing sandbox (running or stopped). The handle provides status, configuration, and lifecycle control without requiring a full connection to the guest agent.

Parameters

name&str

Sandbox name, up to 128 UTF-8 bytes.

Returns

SandboxHandle

Handle with status and lifecycle control.

Sandbox::list()

async fn list() -> MicrosandboxResult<SandboxPage>

Example

let page = Sandbox::list().await?;
for h in page.sandboxes {
    println!("{} - {:?}", h.name(), h.status());
}

Return the first page of sandboxes (running, stopped, and crashed), ordered newest first. The default page size is 20.

Returns

SandboxPage

Handles in this page and an optional cursor for the next page.

Sandbox::list_with()

async fn list_with(
    configure: impl FnOnce(SandboxListBuilder) -> SandboxListBuilder,
) -> MicrosandboxResult<SandboxPage>

Return a configured page of sandboxes. Limits must be between 1 and 100. Labels are AND-matched before pagination.

Example

let page = Sandbox::list_with(|list| {
    list.limit(50).label("role", "worker")
}).await?;

if let Some(cursor) = page.next_cursor {
    let next_page = Sandbox::list_with(|list| {
        list.limit(50).cursor(cursor).label("role", "worker")
    }).await?;
}

Sandbox::remove()

async fn remove(name: &str) -> MicrosandboxResult<()>

Example

Sandbox::remove("api").await?;

Delete a stopped sandbox by name. Locally, this removes the same state as sb.remove_persisted(); see Remove for the exact deletion scope. Unlike remove_persisted(), this associated function routes through the default backend and also supports cloud sandboxes. Fails if the sandbox is still running. Stop it first.

Parameters

name&str

Sandbox name, up to 128 UTF-8 bytes.

Sandbox::start()

async fn start(name: &str) -> MicrosandboxResult<Sandbox>

Example

let sb = Sandbox::start("api").await?;

Restart a previously stopped sandbox. The VM reboots using the persisted configuration. Local handles enter attached mode and stop the sandbox when the client process exits; cloud handles do not own the service-managed VM.

Parameters

name&str

Name of a stopped sandbox, up to 128 UTF-8 bytes.

Returns

Sandbox

Running sandbox.

Sandbox::start_detached()

async fn start_detached(name: &str) -> MicrosandboxResult<Sandbox>

Restart a stopped sandbox in detached mode. The sandbox survives after your process exits.

Parameters

name&str

Name of a stopped sandbox, up to 128 UTF-8 bytes.

Returns

Sandbox

Running sandbox.

Instance methods

sb.config()

fn config(&self) -> &SandboxConfig

Example

println!("{} MiB", sb.config().memory_mib);

Access the sandbox’s full configuration.

Returns

&SandboxConfig

Sandbox configuration.

sb.detach()

async fn detach(self)

Example

sb.detach().await; // keeps running in the background

Release the handle without stopping the sandbox. The sandbox continues running as a background process. Reconnect later with Sandbox::get().

sb.drain()

async fn drain(&self) -> MicrosandboxResult<()>

Example

sb.drain().await?;

Start a graceful drain. Existing commands run to completion, but new exec calls are rejected. The sandbox transitions to Stopped when all in-flight commands finish. Useful for zero-downtime rotation of worker sandboxes.

sb.request_drain()

async fn request_drain(&self) -> MicrosandboxResult<()>

Request graceful drain and return once the request is sent. Pair with wait_until_stopped() when the caller needs stopped-state observation.

sb.fs()

fn fs(&self) -> SandboxFsOps<'_>

Example

sb.fs().write("/tmp/hello.txt", "hi").await?;

Get a filesystem handle for reading and writing files inside the running sandbox. See Filesystem for API details.

Returns

SandboxFsOps

Filesystem handle.

sb.kill()

async fn kill(&self) -> MicrosandboxResult<()>

Example

sb.kill().await?; // SIGKILL, no graceful shutdown

Force-terminate the sandbox immediately with SIGKILL. No graceful shutdown - use when the sandbox is unresponsive. Waits up to five seconds for stopped-state observation after the kill request. Pending writes that the workload hasn’t fsync’d may be lost, same durability semantics as a sudden power loss on a physical machine. Prefer stop() for graceful shutdown that gives the workload a chance to flush.

sb.kill_with_timeout()

async fn kill_with_timeout(&self, timeout: Duration) -> MicrosandboxResult<()>

Force-terminate the sandbox and wait up to timeout for stopped-state observation.

sb.request_kill()

async fn request_kill(&self) -> MicrosandboxResult<()>

Request force termination and return once the request is sent, without waiting for stopped-state observation.

sb.metrics()

async fn metrics(&self) -> MicrosandboxResult<SandboxMetrics>

Example

let m = sb.metrics().await?;
println!("cpu {:.1}% · mem {} MiB", m.cpu_percent, m.memory_bytes / 1_048_576);

Get a point-in-time snapshot of the sandbox’s resource usage: CPU, memory, disk I/O, network I/O, optional upper disk usage, and uptime.

Returns

SandboxMetrics

Resource metrics.

sb.metrics_stream()

fn metrics_stream(&self, interval: Duration) -> impl Stream<Item = MicrosandboxResult<SandboxMetrics>>

Example

use futures::StreamExt;

let mut stream = sb.metrics_stream(Duration::from_secs(1));
while let Some(snapshot) = stream.next().await {
    println!("{:.1}%", snapshot?.cpu_percent);
}

Stream resource metrics at a regular interval. Returns an async stream that yields a new snapshot every interval duration.

Parameters

intervalDuration

Time between metric snapshots.

Returns

impl Stream<SandboxMetrics>

Async stream yielding a snapshot each interval.

sb.logs()

fn logs(&self, opts: &LogOptions) -> MicrosandboxResult<Vec<LogEntry>>

Example

use microsandbox::sandbox::{LogOptions, LogSource, Sandbox};

let handle = Sandbox::get("web").await?;

// Default: all user-program output, regardless of pipe/pty mode
let entries = handle.logs(&LogOptions::default())?;

for e in entries {
    let source = match e.source {
        LogSource::Stdout => "OUT",
        LogSource::Stderr => "ERR",
        LogSource::Output => "PTY",
        LogSource::System => "SYS",
    };
    println!(
        "[{}] {} {:?}: {}",
        e.timestamp.to_rfc3339(),
        source,
        e.session_id,
        String::from_utf8_lossy(&e.data).trim_end()
    );
}

// Filtered: last 50 entries from the past hour, including system lines
let recent = handle.logs(&LogOptions {
    tail: Some(50),
    since: Some(chrono::Utc::now() - chrono::Duration::hours(1)),
    sources: vec![
        LogSource::Stdout,
        LogSource::Stderr,
        LogSource::Output,
        LogSource::System,
    ],
    ..Default::default()
})?;

Read captured output from the sandbox’s exec.log. Backed by an on-disk JSON Lines file the runtime writes via the relay tap. Works on running and stopped sandboxes alike; there is no protocol traffic. The same method is available on SandboxHandle for callers that don’t want to start the sandbox first. The default sources are Stdout, Stderr, and Output (PTY-merged). Pass LogSource::System to also include synthetic lifecycle markers and runtime/kernel diagnostic lines. logs() is synchronous because it’s a pure file read.

Parameters

opts&LogOptions

Filters: tail, since, until, sources. LogOptions::default() returns everything for the default sources.

Returns

Vec<LogEntry>

Matching entries in chronological order.

sb.ping()

async fn ping(&self) -> MicrosandboxResult<SandboxPingResult>

Example

let result = sb.ping().await?;
println!("{} reachable in {:?}", result.name, result.latency);

Check whether the running sandbox’s guest agent is reachable. This sends core.ping, returns the SDK-measured round-trip latency, and does not refresh the sandbox idle timer.

Returns

SandboxPingResult

Sandbox name and ping latency.

sb.touch()

async fn touch(&self) -> MicrosandboxResult<SandboxTouchResult>

Example

let result = sb.touch().await?;
println!("{} activity seq {}", result.name, result.activity_seq);

Explicitly refresh the running sandbox’s idle timer. This sends core.touch; use it when keeping an idle sandbox alive is intentional.

Returns

SandboxTouchResult

Sandbox name and agent activity sequence after the touch.

sb.modify()

fn modify(&self) -> SandboxModificationBuilder

Example

let plan = sb.modify()
    .cpus(4)             // live when 4 <= max_cpus
    .memory(4096)        // live when 4096 MiB <= max_memory
    .env("MODE", "prod") // future execs only; the plan warns about this
    .apply()
    .await?;

for r in &plan.resize_status {
    println!("{:?}: requested {} · actual {} · {:?}", r.resource, r.requested, r.actual, r.state);
}

Plan or apply a configuration change. Set what to change (CPUs, memory, env vars, labels, workdir, secrets), then call dry_run() to preview or apply() to commit; both return a SandboxModificationPlan labeling each change live, next start, requires restart, or unsupported. Apply is all-or-nothing. CPU and memory resize live within the max_cpus / max_memory ceilings; raising a ceiling requires a restart. Env and workdir changes affect future execs only. On a stopped sandbox, changes are saved for the next boot. See SandboxModificationBuilder for all setters and msb modify for the CLI.

Returns

SandboxModificationBuilder

Fluent builder; terminate with dry_run() or apply().

sb.name()

fn name(&self) -> &str

Get the sandbox name.

Returns

&str

Sandbox name, up to 128 UTF-8 bytes.

sb.owns_lifecycle()

fn owns_lifecycle(&self) -> bool

Whether this handle owns the sandbox lifecycle. Local attached handles return true; local detached handles and all cloud handles return false, because the cloud worker owns the sandbox process.

Returns

bool

true for a local attached handle.

sb.remove_persisted()

async fn remove_persisted(&self) -> MicrosandboxResult<()>

Example

sb.stop().await?;
sb.remove_persisted().await?;

Delete this stopped sandbox’s persisted state. This receiver-based form is useful when you still hold the Sandbox instance; it has exactly the same deletion scope as Sandbox::remove(name). It does not perform additional cleanup. See Remove for what is deleted and which external resources are preserved.

sb.request_stop()

async fn request_stop(&self) -> MicrosandboxResult<()>

Request graceful shutdown and return once the request is sent, without waiting for stopped-state observation. Pair with wait_until_stopped() when the caller needs the terminal state.

sb.stop()

async fn stop(&self) -> MicrosandboxResult<()>

Example

sb.stop().await?;

Gracefully shut down the sandbox. Lets the sandbox finish writing any pending data to disk before it exits, so files written inside the sandbox aren’t lost across a later restart. Waits up to ten seconds for a clean exit; if the sandbox is still running after that, it is force-killed.

sb.stop_with_timeout()

async fn stop_with_timeout(&self, timeout: Duration) -> MicrosandboxResult<()>

Gracefully shut down the sandbox with an explicit timeout before escalation. Duration::ZERO skips graceful shutdown and force-kills immediately.

sb.stop_and_wait()

async fn stop_and_wait(&self) -> MicrosandboxResult<ExitStatus>

Example

let status = sb.stop_and_wait().await?;
println!("exited: {}", status.success());

Stop the sandbox and wait for the exit status. This is a local-backend compatibility helper; prefer stop() or stop_with_timeout() when the caller only needs stopped-state observation.

Returns

ExitStatus

Exit code and success flag.

sb.wait()

async fn wait(&self) -> MicrosandboxResult<ExitStatus>

Example

let status = sb.wait().await?;

Block until the sandbox exits on its own (without triggering a stop). Returns the exit status.

Returns

ExitStatus

Exit code and success flag.

sb.wait_until_stopped()

async fn wait_until_stopped(&self) -> MicrosandboxResult<SandboxStopResult>

Block until the sandbox is observed in a terminal non-running state. Owned local sandboxes can include process exit details; detached, name-addressed, and cloud-backed sandboxes report the observed backend state. Returns

Type	Description
`SandboxStopResult`	Observed terminal sandbox state

SandboxBuilder

Builder for configuring a sandbox before creation. Obtained via Sandbox::builder(name). Every setter returns Self, so calls chain. Examples are shown on the methods where usage is non-obvious.

sandbox.slug()

fn slug(self, slug: impl Into<String>) -> Self

Request a globally unique cloud slug. When omitted, microsandbox cloud assigns one; creation fails if the requested slug is already taken.

Parameters

slugimpl Into<String>

Requested cloud slug.

sandbox.build()

async fn build(self) -> MicrosandboxResult<SandboxConfig>

Materialize the SandboxConfig without booting the sandbox. Validates the configuration and, if from_snapshot was called, opens the snapshot manifest to pin its image reference and upper-layer source. For booting, use create instead; call detached(true) first for background mode. create() calls build internally.

Returns

SandboxConfig

Validated, ready-to-boot configuration.

sandbox.cpus()

fn cpus(self, count: u8) -> Self

Set the number of virtual CPUs. This is a limit, not a reservation. Default: 1.

Parameters

countu8

Number of vCPUs.

sandbox.max_cpus()

fn max_cpus(self, count: u8) -> Self

Set the boot-time maximum possible virtual CPU capacity. This reserves the envelope a sandbox can use after restart-backed changes and future live CPU activation; it does not increase the effective vCPU count by itself.

Parameters

countu8

Maximum possible vCPUs.

sandbox.create()

async fn create(self) -> MicrosandboxResult<Sandbox>

Boot the sandbox. Local handles use attached mode and stop the sandbox when the client process exits; cloud handles do not own the service-managed VM, so stop or remove cloud sandboxes explicitly.

Returns

Sandbox

Running sandbox.

sandbox.detached()

fn detached(self, detached: bool) -> Self

Example

let sb = Sandbox::builder("worker")
    .image("python")
    .detached(true)
    .create()
    .await?;
sb.detach().await;

Choose whether the sandbox is created in detached/background mode. Detached sandboxes survive the creating process. Defaults to false.

Parameters

detachedbool

When true, create the sandbox in detached mode.

sandbox.create_detached()

async fn create_detached(self) -> MicrosandboxResult<Sandbox>

Example

let sb = Sandbox::builder("worker")
    .image("python")
    .create_detached()
    .await?;
sb.detach().await;

Boot the sandbox in detached mode. This is a compatibility helper for .detached(true).create(). Prefer detached(true) with create() for new code so attached and detached creation use the same flow.

Returns

Sandbox

Running sandbox.

sandbox.disable_network()

fn disable_network(self) -> Self

Fully disable networking. No network interface is created.

sandbox.entrypoint()

fn entrypoint(self, cmd: impl IntoIterator<Item = impl Into<String>>) -> Self

Override the image ENTRYPOINT used by default-workload execution. Sandbox::exec_default combines it with the effective CMD. Literal Sandbox::exec, Sandbox::attach, and Sandbox::shell calls ignore it.

Parameters

cmdimpl IntoIterator

Entrypoint command and arguments.

sandbox.env()

fn env(self, key: impl Into<String>, value: impl Into<String>) -> Self

Set an environment variable visible to all commands. Can be called multiple times. Per-command env vars (via exec_with) are merged on top.

Parameters

keyimpl Into<String>

Variable name.

valueimpl Into<String>

Variable value.

sandbox.hostname()

fn hostname(self, hostname: impl Into<String>) -> Self

Set the guest hostname.

Parameters

hostnameimpl Into<String>

Hostname.

sandbox.idle_timeout()

fn idle_timeout(self, secs: u64) -> Self

Auto-drain the sandbox after this many seconds of inactivity (no active exec sessions). Enforced on the host side.

Parameters

secsu64

Idle timeout in seconds.

sandbox.cmd()

fn cmd(self, cmd: impl IntoIterator<Item = impl Into<String>>) -> Self

Override the image CMD used by default-workload execution. An empty array explicitly clears the image CMD. This describes durable configuration and does not execute anything during create().

let sb = Sandbox::builder("worker")
    .image("example/worker:latest")
    .cmd(["worker.py", "--once"])
    .create()
    .await?;

sandbox.init()

fn init(self, cmd: impl Into<PathBuf>) -> Self

Example

let sb = Sandbox::builder("worker")
    .image("jrei/systemd-debian:12")
    .init("auto")
    .create()
    .await?;

Hand off PID 1 inside the guest to cmd after agentd finishes its boot-time setup. The agent forks; the parent execs the init and becomes PID 1, the agent continues as a child process. See Custom init system for image picks, shutdown semantics, and tradeoffs. cmd is either an absolute path inside the guest rootfs or the literal "auto". Auto first honors a known init at the start of the image ENTRYPOINT, such as /init in s6-overlay images, then falls back to probing /sbin/init, /lib/systemd/systemd, and /usr/lib/systemd/systemd inside the guest. When attached msb run uses an image-declared init entrypoint, the remaining ENTRYPOINT plus CMD or trailing command is passed to that init instead of direct-executed through agentd. For init binaries that take argv or extra env (rare), use init_with.

Parameters

cmdimpl Into<PathBuf>

Absolute path inside the guest, or “auto”.

sandbox.init_with()

fn init_with(
    self,
    cmd: impl Into<PathBuf>,
    f: impl FnOnce(InitOptionsBuilder) -> InitOptionsBuilder,
) -> Self

Example

let sb = Sandbox::builder("worker")
    .image("jrei/systemd-debian:12")
    .init_with("/lib/systemd/systemd", |i| i
        .args(["--unit=multi-user.target"])
        .env("container", "microsandbox"))
    .create()
    .await?;

Like init, but with a closure-builder for argv and env vars. Mirrors exec_with in shape. The builder exposes arg, args, env, and envs. Calling init or init_with more than once overwrites, unlike env, which appends. The init is one-shot pre-boot.

Parameters

cmdimpl Into<PathBuf>

Absolute path to the init binary inside the guest.

fFnOnce(InitOptionsBuilder)

Closure populating argv and env.

sandbox.image()

fn image(self, image: impl IntoImage) -> Self

Set the root filesystem source. Accepts OCI image names, local directory paths, or disk image paths. The format is auto-detected.

Parameters

imageimpl IntoImage

OCI image name, local directory path, or disk image path.

sandbox.image_with()

fn image_with(self, f: impl FnOnce(ImageBuilder) -> ImageBuilder) -> Self

Example

use microsandbox::size::SizeExt;

let sb = Sandbox::builder("worker")
    .image_with(|i| i.oci("python:3.12").root_disk(8.gib()))
    .create()
    .await?;

Configure an explicit rootfs source. Use this for OCI-only settings such as the writable root disk, or for disk images when the filesystem type can’t be auto-detected.

Parameters

fFnOnce(ImageBuilder)

Configure the rootfs source.

sandbox.log_level()

fn log_level(self, level: LogLevel) -> Self

Override the sandbox process’s log verbosity.

Parameters

levelLogLevel

Log level.

sandbox.max_duration()

fn max_duration(self, secs: u64) -> Self

Set the maximum sandbox lifetime in seconds. When exceeded, the sandbox is drained and stopped. Enforced on the host side - the guest cannot override it.

Parameters

secsu64

Maximum lifetime in seconds.

sandbox.memory()

fn memory(self, size: impl Into<Mebibytes>) -> Self

Set the guest memory size. Physical pages are only allocated as the guest touches them, so this is a limit, not an upfront reservation. Default: 512 MiB.

Parameters

sizeimpl Into<Mebibytes>

Memory in MiB.

sandbox.max_memory()

fn max_memory(self, size: impl Into<Mebibytes>) -> Self

Set the boot-time maximum hotpluggable guest memory. This reserves the envelope a sandbox can use after restart-backed changes and future live memory activation; it does not increase the effective memory by itself.

Parameters

sizeimpl Into<Mebibytes>

Maximum memory in MiB.

sandbox.thp()

fn thp(self, policy: TransparentHugePagePolicy) -> Self

Select the guest transparent huge-page policy applied through the kernel command line at boot. Default: TransparentHugePagePolicy::Madvise.

Parameters

policyTransparentHugePagePolicy

Always, Madvise, or Never.

sandbox.network()

fn network(self, f: impl FnOnce(NetworkBuilder) -> NetworkBuilder) -> Self

Configure networking. See Networking for the full builder API.

Parameters

fNetworkBuilder

Configure the network.

sandbox.patch()

fn patch(self, f: impl FnOnce(PatchBuilder) -> PatchBuilder) -> Self

Modify the rootfs before the VM boots. Patches go into the writable layer - the base image is untouched. See PatchBuilder for the operations.

Parameters

fFnOnce(PatchBuilder)

Configure rootfs patches.

sandbox.port()

fn port(self, host_port: u16, guest_port: u16) -> Self

Publish a TCP port from the sandbox to the host. The default host bind address is 127.0.0.1.

Parameters

host_portu16

guest_portu16

Port inside the sandbox.

sandbox.port_bind()

fn port_bind(self, host_bind: IpAddr, host_port: u16, guest_port: u16) -> Self

Parameters

host_portu16

Port on the host.

guest_portu16

Port inside the sandbox.

sandbox.port_udp_bind()

fn port_udp_bind(self, host_bind: IpAddr, host_port: u16, guest_port: u16) -> Self

Publish a UDP port on a specific host bind address.

Parameters

sandbox.pull_policy()

fn pull_policy(self, policy: PullPolicy) -> Self

Control when the OCI image is pulled from the registry.

Parameters

policyPullPolicy

Pull behavior.

sandbox.registry()

fn registry(self, f: impl FnOnce(RegistryConfigBuilder) -> RegistryConfigBuilder) -> Self

Example

use microsandbox::{RegistryAuth, Sandbox};

let sb = Sandbox::builder("worker")
    .image("registry.example.com/team/app:latest")
    .registry(|r| r.auth(RegistryAuth::Basic {
        username: "user".into(),
        password: "token".into(),
    }))
    .create()
    .await?;

Configure registry connection settings for the sandbox image pull, including explicit auth, insecure HTTP, and custom CA certificates.

Parameters

fRegistryConfigBuilder

Closure that configures registry auth and TLS options.

sandbox.replace()

fn replace(self) -> Self

If a sandbox with the same name already exists, stop it, remove it, and create a fresh one. Without this, creation fails on name conflict.

sandbox.script()

fn script(self, name: impl Into<String>, content: impl Into<String>) -> Self

Add a named script at /.msb/scripts/ inside the guest. Scripts are added to PATH and can be called by name via exec() or shell().

Parameters

nameimpl Into<String>

Script name (becomes the filename).

contentimpl Into<String>

Script content.

sandbox.secret()

fn secret(self, f: impl FnOnce(SecretBuilder) -> SecretBuilder) -> Self

Add a secret with full configuration. See Secrets for the builder API. Automatically enables TLS interception.

Parameters

fSecretBuilder

Configure the secret.

sandbox.secret_env()

fn secret_env(self, env_var: impl Into<String>, value: impl Into<String>, allowed_host: impl Into<String>) -> Self

Shorthand for adding a header-injected secret. Equivalent to .secret(|s| s.env(env_var).value(value).allow_host(allowed_host)).

Plaintext at rest. The value is persisted verbatim in the durable sandbox config until a later modify rotate migrates the entry to a source reference. Prefer .secret(|s| s.source(..)) when the value can be referenced; use this path when you hold only a value. A future host-side secret store will switch this method to import-then-reference with no signature change.

Parameters

env_varimpl Into<String>

Environment variable name (non-empty, no = or NUL).

valueimpl Into<String>

Secret value.

allowed_hostimpl Into<String>

Allowed destination host.

sandbox.shell()

fn shell(self, shell: impl Into<String>) -> Self

Set the shell used by Sandbox::shell(). Default: /bin/sh.

Parameters

shellimpl Into<String>

Shell path (e.g. “/bin/bash”).

sandbox.user()

fn user(self, user: impl Into<String>) -> Self

Set the default guest user for all commands.

Parameters

userimpl Into<String>

User name or UID.

sandbox.volume()

fn volume(self, guest_path: impl Into<String>, f: impl FnOnce(MountBuilder) -> MountBuilder) -> Self

Add a volume mount. See Volumes for mount types.

Absolute path inside the guest.

PatchBuilder

Builder for pre-boot root filesystem patches.

patch.append()

Directory mode, e.g. Some(0o755).

patch.remove()

fn remove(self, path: impl Into<String>) -> Self

Delete a file or directory at path. Idempotent: a no-op if the path doesn’t exist.

Parameters

pathimpl Into<String>

Absolute path inside the guest.

SandboxModificationBuilder

Builder for planning or applying sandbox configuration changes.

modification.apply()

async fn apply(self) -> MicrosandboxResult<SandboxModificationPlan>

Apply the changes. Live changes are made to the running sandbox first, and the new config is saved only after they succeed, so a failed apply leaves the old config in place. Changes for a stopped sandbox, or requested with next_start(), are saved and take effect on the next start. With restart(), the sandbox is stopped and started so that restart-required changes take effect. A live CPU or memory resize can take a moment to settle. The returned plan’s resize_status reports progress per resource; see ResourceResizeStatus.

Returns

SandboxModificationPlan

The applied plan, with applied: true and live resize outcomes in resize_status.

modification.cpus()

fn cpus(self, cpus: u8) -> Self

Set the desired effective vCPU count. Applies live to a running sandbox when the target fits inside the booted max_cpus; otherwise it requires a restart.

Parameters

cpusu8

Number of vCPUs.

modification.max_cpus()

fn max_cpus(self, max_cpus: u8) -> Self

Set the desired boot-time maximum possible vCPU count. Capacity is fixed at boot, so this is always restart-backed on a running sandbox.

Parameters

max_cpusu8

Maximum possible vCPUs.

modification.dry_run()

async fn dry_run(self) -> MicrosandboxResult<SandboxModificationPlan>

Example

let plan = sb.modify().cpus(8).dry_run().await?;

for change in &plan.changes {
    if let PlannedChange::Config(c) = change {
        println!("{}: {:?} -> {:?} ({:?})", c.field, c.before, c.after, c.disposition);
    }
}

Compute the modification plan without applying anything. Use it to preview how each change classifies and whether conflicts block the patch.

Returns

SandboxModificationPlan

The plan, with applied: false.

modification.env()

fn env(self, key: impl Into<String>, value: impl Into<String>) -> Self

Set an environment variable for future execs. Can be called multiple times. On a running sandbox this applies to future execs only; running processes keep their current environment.

Parameters

keyimpl Into<String>

Variable name.

valueimpl Into<String>

Variable value.

modification.remove_env()

fn remove_env(self, key: impl Into<String>) -> Self

Remove an environment variable. Same future-execs-only semantics as env().

Parameters

keyimpl Into<String>

Variable name to remove.

modification.label()

fn label(self, key: impl Into<String>, value: impl Into<String>) -> Self

Set a sandbox label. Can be called multiple times.

Parameters

keyimpl Into<String>

Label key.

valueimpl Into<String>

Label value.

modification.remove_label()

fn remove_label(self, key: impl Into<String>) -> Self

Remove a sandbox label.

Parameters

keyimpl Into<String>

Label key to remove.

modification.memory()

fn memory(self, size: impl Into<Mebibytes>) -> Self

Set the desired effective guest memory. Applies live to a running sandbox when the target fits inside the booted max_memory; otherwise it requires a restart.

Parameters

sizeimpl Into<Mebibytes>

Memory in MiB.

modification.memory_mib()

fn memory_mib(self, memory_mib: u32) -> Self

Set the desired effective guest memory in MiB. Same as memory() with an explicit unit.

Parameters

memory_mibu32

Memory in MiB.

modification.max_memory()

fn max_memory(self, size: impl Into<Mebibytes>) -> Self

Set the desired boot-time maximum hotpluggable memory. Capacity is fixed at boot, so this is always restart-backed on a running sandbox.

Parameters

sizeimpl Into<Mebibytes>

Maximum memory in MiB.

modification.max_memory_mib()

fn max_memory_mib(self, max_memory_mib: u32) -> Self

Set the desired boot-time maximum hotpluggable memory in MiB. Same as max_memory() with an explicit unit.

Parameters

max_memory_mibu32

Maximum memory in MiB.

modification.next_start()

fn next_start(self) -> Self

Persist the requested changes for the next start, leaving any running VM unchanged. Every change classifies as next start.

modification.restart()

fn restart(self) -> Self

Plan under restart-backed apply semantics. When the patch contains restart-required changes, apply() stops the sandbox, persists the config, and starts it again so the changes become active now.

modification.secret()

fn secret(self, f: impl FnOnce(SecretPatchBuilder) -> SecretPatchBuilder) -> Self

Example

use microsandbox::sandbox::SecretSource;

let plan = sb.modify()
    .secret(|s| s
        .env("API_KEY")
        .source(SecretSource::Env { var: "API_KEY".into() })
        .allow_host("api.example.com"))
    .apply()
    .await?;

Declare the desired state of one secret via a SecretPatchBuilder closure. The spec mirrors the create-time SecretBuilder vocabulary, and the planner diffs it against the existing config to infer the change: a secret that does not exist yet is added, material on an existing secret rotated, and host or placeholder differences update those aspects. Declaring the same secret again replaces the earlier spec; removal is always explicit through remove_secret().

Parameters

fFnOnce(SecretPatchBuilder)

Closure declaring the secret’s desired state.

modification.remove_secret()

fn remove_secret(self, name: impl Into<String>) -> Self

Remove a secret. Removal is always explicit; omitting a secret from the patch never removes it.

Parameters

nameimpl Into<String>

Secret name (its environment variable name).

modification.workdir()

fn workdir(self, path: impl Into<String>) -> Self

Set the working directory for future execs. On a running sandbox this applies to future execs only.

Parameters

pathimpl Into<String>

Absolute path inside the guest.

SecretPatchBuilder

Used by secret()

Builder for one declarative secret change.

secret.env()

fn env(self, name: impl Into<String>) -> Self

Name the secret. This is the environment variable that exposes the placeholder inside the guest. Required.

Parameters

nameimpl Into<String>

Secret name, usually the environment variable name.

secret.source()

fn source(self, source: SecretSource) -> Self

Provide the secret material as a host-side SecretSource reference. The durable config records only the reference, and the value is resolved host-side when the change applies. Mutually exclusive with value(...).

Parameters

sourceSecretSource

Host-side reference for the secret material.

secret.value()

fn value(self, value: impl Into<String>) -> Self

Provide the secret material as a raw value, for embedders that hold only a value. The value is zeroized on drop, redacted from Debug, and never enters the plan. Applying a value persists it into the durable config until a later source-based rotate migrates it to a reference, the same at-rest property as secret_env(). Mutually exclusive with source(...).

Parameters

valueimpl Into<String>

Raw secret value held by the embedding process.

secret.placeholder()

fn placeholder(self, placeholder: impl Into<String>) -> Self

Set the guest-visible placeholder. Placeholder changes cannot reach already-running processes, so they classify as requires restart on a running sandbox.

Parameters

placeholderimpl Into<String>

Guest-visible placeholder string.

secret.allow_host()

fn allow_host(self, host: impl Into<String>) -> Self

Add an allowed host pattern, such as api.example.com, *.example.org, or *. A non-empty list replaces the secret’s current allow-list; an empty list leaves it unchanged. A new secret needs at least one.

Parameters

hostimpl Into<String>

Allowed exact host, wildcard host pattern, or *.
