Compose stack replacing start-maven.sh's bare `&`-backgrounded processes. Single multi-stage image builds all six daemons (CGO + prebuilt native libs from deps/); compose runs one container each with a different command. Only mavend mounts the encryption key (env_file, gitignored) and the db volume; the modules mount just the shared unix-socket dir and read-only models — so the "key-free modules" boundary is OS-enforced (separate namespaces), not just a code convention. IPC stays unix-domain over a shared volume: zero code change, paths move to /run/maven. Encrypted db at rest on a named volume, decrypted working copy in tmpfs (RAM) per the at-rest encryption landed earlier. Validated: `docker compose config` clean, mavend.json parses, all daemon flags confirmed. NOT build-tested (no docker/GPU in authoring env) — deploy/README.md lists the host-dependent tweak points (GPU passthrough, onnxruntime path, cross-container voice bind, netdata host). Chosen Docker over interim systemd units per the "dockerize soon" call — no throwaway supervisor built. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Maven — Docker deployment
One image, one container per daemon (docker-compose.yml). Core (mavend)
holds the encryption key and the db; the modules mount only the shared socket
dir and read-only models.
First run
# 1. generate the at-rest db key (32 bytes, base64) — keep it safe, losing it loses the db
cp deploy/db_key.env.example deploy/db_key.env
printf 'MAVEN_DB_KEY=%s\n' "$(openssl rand 32 | base64 -w0)" > deploy/db_key.env
# 2. build + start
docker compose build
docker compose up -d
# 3. logs
docker compose logs -f mavend
models/ and deps/ are bind-mounted / baked from the host — they are NOT in
git (fetched via make deps + downloaded models). The build context needs
deps/lib, deps/piper, deps/include, and deps/whisper.cpp/ggml/include
present (see .dockerignore).

Not yet verified / host-dependent
This stack is correct-by-construction but has not been build-tested here (no docker in the authoring env; ~1GB context; GPU). Expect a tweak on first build on the target host, most likely in one of these:
- GPU passthrough —
mavsttdmaps/dev/drifor Vulkan. On an NVIDIA host you'd swap to the nvidia container runtime instead of/dev/dri. - onnxruntime lib path —
mavend's embedder needslibonnxruntime.so(onLD_LIBRARY_PATH=/opt/maven/lib). If the embedder wants an explicit path, set it in the config's embedder block. - cross-container voice —
mavweb -voice mavend:9100only works oncemavendbinds its voice server on0.0.0.0:9100(Voice config, currently unset). Until then, voice-over-web is inert;/tools, passkey, and the dash work fine over the core socket. - netdata —
mavpollreaches it viahost.docker.internal; adjust if netdata runs elsewhere.
