lark-cli init image (Pattern A)

This image provisions the sandbox lark-cli runtime binary into a Kubernetes sandbox Pod via an init container + shared emptyDir, instead of the Gateway downloading Linux binaries from GitHub at install time and mounting them via hostPath/PVC.

What it does

• Build time (network available): downloads and SHA-256-verifies the official larksuite/cli Linux release binaries and stages the runtime layout under /opt/lark-cli:

  /opt/lark-cli/bin/lark-cli            # arch-dispatch launcher (uname -m)
  /opt/lark-cli/linux-amd64/lark-cli
  /opt/lark-cli/linux-arm64/lark-cli
  /opt/lark-cli/.deerflow-lark-cli-runtime.json   # {"version": "vX.Y.Z"}
  

  This is byte-identical to what the Gateway writer (_write_lark_cli_sandbox_launcher) produces and what _validate_lark_cli_sandbox_runtime enforces, so the sandbox PATH contract (/mnt/integrations/lark-cli/runtime/bin/lark-cli) is unchanged.

• Run time: copies /opt/lark-cli/. into the emptyDir mounted at ${LARK_CLI_RUNTIME_DEST} (default /mnt/integrations/lark-cli/runtime) and exits 0.

Build

docker build -t deer-flow/lark-cli-init:v1.0.65 \
  --build-arg LARK_CLI_VERSION=v1.0.65 \
  docker/lark-cli-init

The tag should encode the lark-cli version so it can be bumped independently of the upstream all-in-one-sandbox sandbox image.

CI publishes multi-arch (linux/amd64,linux/arm64) images to ghcr.io/<owner>/deer-flow-lark-cli-init:<lark-cli-version> via .github/workflows/lark-cli-images.yaml (run it with a lark_cli_version input, or push a lark-cli-v* tag). This is decoupled from the DeerFlow v* release because the image tracks the upstream larksuite/cli version.

Wiring it into the provisioner

The init-container runtime path is opt-in and off by default. Enable it by publishing this image and pointing the provisioner at it:

• Set LARK_CLI_INIT_IMAGE on the provisioner service to the published tag (e.g. deer-flow/lark-cli-init:v1.0.65). Empty ⇒ legacy hostPath / Gateway download path (no behavior change).
• When set, the provisioner adds a lark-cli-runtime emptyDir volume, an lark-cli-init init container, and a read-only runtime mount on the sandbox container — and ignores any /mnt/integrations/lark-cli/runtime hostPath/PVC extra mount (the init container supersedes it). The per-user config / data credential mounts are unchanged.
• The provisioner reports whether it is configured via GET /api/capabilities ({"lark_cli_init_image": true|false}), which the Gateway surfaces as the Lark integration sandbox-runtime readiness signal in /api/integrations/lark/status.

Opt-in note: the init-container path stays off until LARK_CLI_INIT_IMAGE is set on the provisioner, so an unpublished or unconfigured image is a no-op (legacy hostPath / Gateway download path, no behavior change).
