# docker/ — worker image & bridge

## lvmh-worker image (`worker.Dockerfile`)

Headless pi worker: node 24, pi (global npm), golang, git, ripgrep, make, jq,
gopls, plus the user's pi config baked from dotfiles (`deploy/rsync-pi-agent.sh`:
settings/skills/agents/extensions; no auth.json/sessions/cache; `git:` packages
dropped — postinstalls crash headless installs).

## Per-repo setup hook (agent-driven image setup)

The agent works as root with network access, so it can `apt-get install` /
`go install` anything **in-session**. Containers are ephemeral, so system
packages vanish on container stop. For durability, a repo can ship:

    /workspace/.lvmh/setup.sh

The bridge (`bridge/index.mjs`) runs it with bash on **every spawn** before the
pi session starts (10-min timeout, failure is non-fatal — logged, session
continues). Since `/workspace` is a persistent per-repo volume, the hook
survives container death. Agents that need extra tooling should write that
script into the repo (e.g. `apt-get update && apt-get install -y sqlite3`).

## bridge/index.mjs

Hosts the SDK session (`createAgentSession` + `bindExtensions({mode:"rpc"})` —
the SDK never fires `session_start` without the explicit bind, and the lvmh
plugin dials home off that event).
