OpenHands/scripts/dev-docker.mjs

/**
 * Dockerized Development Stack
 *
 * Same as `dev-with-automation.mjs` (Vite + ingress + automation backend),
 * but runs the agent-server inside a Docker container instead of via `uvx`.
 *
 * The agent-server image listens on port 8000 inside the container; we map
 * it to the host's `agentServerPort` (default 18000) so the ingress proxy
 * and the secret-seeding step can reach it via http://localhost:18000.
 *
 * Required environment variables:
 *   - PROJECT_PATH: Absolute host path to your projects. Mounted into the
 *     container at /projects so the agent can read/edit your code. The
 *     frontend always treats /projects as a "workspace parent", so the
 *     dropdown lists its immediate subdirectories as workspaces.
 *
 * Optional environment variables:
 *   - OH_AGENT_SERVER_GIT_REF: Git ref (branch/tag/SHA) of the agent-server
 *     to use. Translates to the docker tag `${ref}-python`, e.g.
 *     `main` -> `ghcr.io/openhands/agent-server:main-python`.
 *   - OH_AGENT_SERVER_LOCAL_PATH: Absolute host path to a software-agent-sdk
 *     checkout. When set, mounts the checkout at /agent-server-src inside the
 *     container and reinstalls the four workspace packages
 *     (openhands-{sdk,tools,workspace,agent-server}) as editable installs on
 *     top of the image's pre-built venv before starting the server. Source
 *     edits on the host are reflected in the running container on module
 *     reload / process restart, matching the non-Docker dev loop.
 *
 * Optional credential mounts (only mounted when the host path exists):
 *   - ~/.openhands -> /home/openhands/.openhands  (persistence)
 *   - ~/.claude    -> /home/openhands/.claude     (Claude credentials)
 *   - ~/.codex     -> /home/openhands/.codex      (Codex credentials)
 *   - ~/.ssh       -> /home/openhands/.ssh        (git/ssh access)
 *
 * Optional host home mount (opt-in):
 *   Set `OH_MOUNT_HOST_HOME=1` to bind-mount your entire host home onto
 *   the container user's home at `/home/openhands`. This lets the
 *   "Add Workspace" file browser navigate your real host filesystem
 *   (and credentials/persistence dirs above are picked up automatically
 *   as subpaths). Off by default so the container stays isolated from
 *   the host home unless you opt in.
 *
 * Usage:
 *   PROJECT_PATH=/path/to/your/projects npm run dev:docker
 *   OH_AGENT_SERVER_GIT_REF=main PROJECT_PATH=... npm run dev:docker
