Python Sandbox SDK reference

Import the top-level client from porter_sandbox:

from porter_sandbox import Porter, AsyncPorter

`Porter`

Porter is the top-level sync client. It exposes resource namespaces for sandboxes, volumes, health, and readiness.

from porter_sandbox import Porter

with Porter() as porter:
    sandbox = porter.sandboxes.create(
        image="python:3.12-slim",
        name="my-sandbox",
    )

Constructor options:

Option	Type	Description
`api_key`	`str \| None`	Optional API key. Only required when invoking the Sandbox API from outside the sandbox-enabled cluster. Create one from Settings > API tokens in the Porter Dashboard. Creating API tokens requires admin permissions.
`base_url`	`str \| None`	Optional API base URL override. In-cluster Porter Applications use the in-cluster Sandbox API URL by default.
`timeout`	`float \| None`	Request timeout in seconds. Defaults to 30 seconds.

`porter.sandboxes`

`create`

sandbox = porter.sandboxes.create(
    image="python:3.12-slim",
    name="my-sandbox",
    command=None,
    args=None,
    env=None,
    tags={"workflow": "demo"},
    volume_mounts=None,
)

Arguments:

Argument	Type	Description
`image`	`str`	Container image to run.
`name`	`str \| None`	Optional cluster-unique sandbox name. Use lowercase letters, numbers, and hyphens; start and end with a letter or number. Names currently cannot be reused, even after termination.
`command`	`list[str] \| None`	Optional entrypoint override.
`args`	`list[str] \| None`	Optional arguments passed to the command.
`env`	`dict[str, str] \| None`	Environment variables to set in the sandbox.
`tags`	`dict[str, str] \| None`	Key-value labels for finding related sandboxes.
`volume_mounts`	`dict[str, str] \| None`	Volume IDs keyed by absolute mount path inside the sandbox.

Returns a Sandbox handle. create returns once the request is recorded, which is before the container is necessarily running — the sandbox may still be in queued (waiting for capacity) or creating. Call sandbox.refresh() until sandbox.phase == "running" before calling exec.

`get`

sandbox = porter.sandboxes.get("my-sandbox")

Looks up a sandbox by name and returns a Sandbox handle. Use names as the canonical reference for sandboxes you need to operate on later.

`list`

sandboxes = porter.sandboxes.list(tags={"workflow": "demo"}, page=1)

Lists sandboxes, optionally filtered by tags and page.

`Sandbox`

Sandbox is the handle returned by porter.sandboxes. Properties:

Property	Type	Description
`id`	`str`	Sandbox identifier.
`phase`	`StatusResponsePhase \| None`	Last-known lifecycle phase.
`tags`	`dict[str, str] \| None`	Last-known tags.

Methods:

status = sandbox.refresh()
result = sandbox.exec(["python", "-c", "print('hi')"])
logs = sandbox.logs(limit=100)
sandbox.terminate()

Method	Description
`refresh()`	Refetches status and updates `phase` and `tags`.
`exec(command)`	Runs a command in the sandbox and returns stdout, stderr, and exit code.
`logs(since=None, limit=None)`	Fetches structured log lines.
`terminate()`	Terminates the sandbox.

Volumes

Volumes are persistent storage that can be mounted into sandboxes.

volume = porter.volumes.create(name="my-data")

sandbox = porter.sandboxes.create(
    image="python:3.12-slim",
    volume_mounts={"/mnt/data": volume.id},
)

Sandbox and volume names may contain lowercase letters, numbers, and hyphens, and must start and end with a letter or number. Sandbox names currently cannot be reused, even after termination. Volume names must be unique for the lifetime of the volume and can be reused after deletion. Volume methods:

Method	Description
`porter.volumes.list()`	Lists volumes.
`porter.volumes.create(name=None)`	Creates a volume. Pass a name when you need stable lookup later.
`porter.volumes.get(name)`	Fetches a volume by name.
`porter.volumes.delete(name)`	Deletes a volume by name.

Async client

AsyncPorter mirrors Porter with awaitable methods:

from porter_sandbox import AsyncPorter

async with AsyncPorter() as porter:
    sandbox = await porter.sandboxes.create(
        image="python:3.12-slim",
        name="async-sandbox",
    )
    result = await sandbox.exec(["python", "-c", "print('hi')"])
    await sandbox.terminate()

Low-level client

The top-level client exposes generated low-level clients through .raw:

raw_client = porter.raw
raw_sandboxes = porter.sandboxes.raw

Use these only when you need an endpoint that is not wrapped by the ergonomic SDK surface yet.
