watasu 0.1.12

Python SDK for Watasu

Watasu Python SDK

Python SDK for Watasu.

Install

pip install watasu

Set WATASU_API_KEY before using the SDK.

Usage

from watasu import Sandbox

sbx = Sandbox()
sbx.files.write("/home/user/a.py", "print(2 + 2)")
result = sbx.commands.run("python /home/user/a.py")
print(result.stdout)
sbx.kill()

Sandbox(), Sandbox.create, and Sandbox.connect return only after the Watasu API supplies a usable data-plane session. The SDK does not poll sandbox readiness.

sbx.beta_pause()
sbx.resume(timeout=300)

from watasu import Sandbox

with Sandbox.create() as sbx:
    result = sbx.commands.run("echo hello")
    print(result.stdout)

Leaving the context manager calls kill().

Listing Sandboxes

from watasu import Sandbox

paginator = Sandbox.list(
    query={"metadata": {"purpose": "ci"}, "state": ["running"]},
    limit=20,
)

for sandbox in paginator.list_items():
    print(sandbox.sandbox_id, sandbox.state)

Git, Watch, PTY, And Signed File URLs

from watasu import PtySize, Sandbox

with Sandbox.create() as sbx:
    sbx.git.init("/workspace/new-project", initial_branch="main")
    sbx.git.clone(
        "https://github.com/acme/project.git",
        path="/workspace/project",
        branch="main",
        depth=1,
    )
    status = sbx.git.status("/workspace/project")
    sbx.git.configure_user(
        "Watasu Bot",
        "[e-mail]",
        scope="local",
        path="/workspace/project",
    )
    sbx.git.create_branch("/workspace/project", "feature/docs")
    sbx.git.add("/workspace/project", files=["README.md"])
    sbx.git.commit(
        "/workspace/project",
        "Update docs",
        author_name="Watasu Bot",
        author_email="[e-mail]",
    )
    sbx.git.push(
        "/workspace/project",
        remote="origin",
        branch="feature/docs",
        set_upstream=True,
    )
    remote_url = sbx.git.remote_get("/workspace/project", "origin")
    sbx.git.restore("/workspace/project", paths=["README.md"])
    sbx.git.reset("/workspace/project", mode="hard", target="HEAD")

    watcher = sbx.files.watch_dir("/workspace/project", recursive=True)
    sbx.files.write_files(
        [
            {"path": "/workspace/project/a.txt", "data": "alpha"},
            {"path": "/workspace/project/b.bin", "data": b"\x00\x01\x02"},
        ]
    )

    terminal = sbx.pty.create(PtySize(rows=30, cols=100))
    terminal.send_stdin("echo hello\n")
    result = terminal.wait()

    upload_url = sbx.upload_url("/workspace/input.bin")
    download_url = sbx.download_url("/workspace/output.bin")

    events = watcher.get_new_events()
    watcher.stop()

Network Policy

with Sandbox.create(
    network={
        "allow_out": ["pypi.org:443"],
        "deny_out": ["169.254.169.254"],
    }
) as sbx:
    sbx.update_network(
        allow_internet_access=False,
        allow_package_registry_access=True,
        allow_out=["pypi.org:443", "registry.npmjs.org:443"],
    )

Metrics And Snapshots

from watasu import Sandbox

with Sandbox.create() as sbx:
    metrics = sbx.get_metrics()
    snapshot = sbx.create_snapshot(name="ready")
    snapshots = sbx.list_snapshots().list_items()
    restored = sbx.restore(snapshot_id=snapshot.snapshot_id)
    sbx.delete_snapshot(snapshot.snapshot_id)

Watasu snapshots are backed by sandbox checkpoints. Use the returned snapshot_id when restoring from a checkpoint.

Async API

from watasu import AsyncSandbox


async def main() -> None:
    async with await AsyncSandbox.create() as sbx:
        result = await sbx.commands.run("echo hello")
        print(result.stdout)

        metrics = await sbx.get_metrics()
        snapshot = await sbx.create_snapshot(name="ready")
        snapshots = await sbx.list_snapshots().list_items()
        await sbx.delete_snapshot(snapshot.snapshot_id)

Unsupported surfaces raise explicit not-implemented errors instead of silently falling back to client-side polling.
