drukbox-python-sdk 0.0.7

Async Python client for Drukbox.

drukbox-python-sdk

Async Python client for the Drukbox host API.

The SDK provisions sandbox VMs, reads host state, deletes hosts, and returns the SSH connection details a caller needs. It speaks HTTP only: SSH sessions, file transfer, command execution, and retry orchestration belong in the caller.

Install

pip install drukbox-python-sdk
uv add drukbox-python-sdk

Usage

from drukbox_sdk import SandboxAPI

sandbox = SandboxAPI(
    base_url="https://sandbox.internal.ts.net",
    token="...",
)

try:
    host = await sandbox.create_host(
        image="ghcr.io/drukbox/sandbox:abc123",
        env={"FOO": "bar"},
        idempotency_key="agent-run-42",
    )
    # Dial whichever reachable address fits your network: host.external_ssh_host
    # for the provider's public path (may be empty when the service runs an
    # AWS-with-Tailscale-on deployment) or host.internal_ssh_host for the
    # tailnet MagicDNS name (only when Tailscale is enabled). Use host.known_hosts
    # for SSH host-key verification. If the provider mints a per-VM keypair
    # (AWS with Tailscale off), host.private_key carries the private half —
    # returned exactly once at create time; subsequent get_host returns None.
finally:
    await sandbox.delete_host(host.id)
    await sandbox.aclose()

create_host blocks until the host is active — typically ~10–30s, up to a few minutes worst case. The SDK's default timeout (300s) covers this. Pass an idempotency_key for retry safety: a retry with the same key after a successful provision returns the original host instead of creating a duplicate.

SandboxAPI.from_env(prefix="SANDBOX_") reads SANDBOX_SERVICE_URL, SANDBOX_SERVICE_TOKEN, and optional SANDBOX_SERVICE_TIMEOUT.

Contract

Public exports live in drukbox_sdk:

• SandboxAPI
• SandboxHost
• DoctorReport and DoctorCheck
• HTTPProxy and HTTPProxyAttachment
• SandboxAPIError and typed subclasses for auth, not found, conflict, unavailable, and unclassified response errors

Supported host operations:

• create_host
• get_host
• attach
• list_hosts
• renew_host
• delete_host
• doctor
• aclose

create_host supports the service's optional image, env, expires_at, provider, instance_type, disk_gb, and Idempotency-Key inputs. instance_type (provider-native size, e.g. t3.xlarge / cx33) and disk_gb pin the VM shape; omit either for the provider default. expires_at mirrors the wire contract: omit it for the default lease, pass a datetime for an explicit expiry, or pass None for a never-reaped (permanent) host.

renew_host extends a host's lease via POST /hosts/{id}/renew. Omit expires_at to extend by the service's default TTL; renewal never makes a host permanent.

Supported HTTP-proxy operations:

• create_http_proxy
• delete_http_proxy
• attach_http_proxy
• detach_http_proxy

HTTP proxies are account-bound exe.dev resources, not host state — deleting a host does not remove proxies fronting it. create_http_proxy takes an origin-only target (scheme + host, no path/query/fragment/credentials) and at least one headers entry; attach_http_proxy / detach_http_proxy point a proxy at a host's backing VM (the host must be bootstrapping or active).

doctor fetches GET /doctor — read-only dependency health. The service runs one cheap, non-mutating probe per dependency (database, active VM provider, Tailscale when enabled) and always responds 200, so callers branch on DoctorReport.ok rather than the HTTP status. A failed DoctorCheck carries a stable hint slug for remediation.

The SDK does not mint Tailscale auth keys, manage ACLs, establish SSH, provision Linux users, transfer files, or run remote commands.

Tests use respx to fake the Drukbox HTTP API. They do not need a real network, VM provider, or Drukbox service.
