#
# DeerFlow "lark-cli init" image (Pattern A).
#
# Purpose: provide the sandbox `lark-cli` runtime binary to a Kubernetes sandbox
# Pod via an init container + shared `emptyDir`, instead of downloading Linux
# binaries from GitHub at install time and mounting them via hostPath/PVC.
#
# At BUILD time (network available) this image downloads and SHA-256-verifies the
# official `larksuite/cli` Linux release binaries and stages the runtime layout:
#
#   /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 layout 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.
#
# At RUN time the default command copies `/opt/lark-cli/.` into the shared
# emptyDir mounted at `/mnt/integrations/lark-cli/runtime` and exits.
#
# The image tag should encode the lark-cli version so it can be bumped
# independently of the upstream `all-in-one-sandbox` image.
#
# Build (defaults to the pinned version below):
#   docker build -t deer-flow/lark-cli-init:v1.0.65 \
#     --build-arg LARK_CLI_VERSION=v1.0.65 docker/lark-cli-init
