Install mempalace via pip in the Dockerfile. Provides 29 MCP tools
for semantic search over conversation history, knowledge graph
queries, agent diaries, and wing/room/drawer management. Everything
runs locally — no API keys, no data egress.
Integration:
- Dockerfile: pip install mempalace (with --break-system-packages
for Debian trixie PEP 668 compliance)
- entrypoint-user.sh: auto-initializes palace for /workspace on
first run (idempotent, skips if palace exists)
- entrypoint.sh: adds ~/.mempalace to the volume ownership-fix loop
- docker-compose.yml + shared: optional devbox-palace named volume
at ~/.mempalace (commented out by default — user opts in)
Users configure MCP integration by adding a mempalace server entry
to their opencode.json. No wrapper plugin needed — the upstream
Python MCP server is used directly.
Docs updated: README.md (new MemPalace section with setup, MCP
config, usage examples, storage details), DOCKER_HUB.md (data
storage table + tools list), CHANGELOG.md (unreleased entry).
Mason LSP installs and Lazy plugin cache live at ~/.local/share/nvim,
which was in the container's writable layer. Every --force-recreate
triggered a full re-download of all plugins and LSP servers on next
nvim launch — slow and wasteful.
Add devbox-nvim-data named volume in docker-compose.yml and
docker-compose.shared.yml, add to entrypoint ownership-fix loop,
update persistence tables in README.md and DOCKER_HUB.md.
Zoxide stores its database at ~/.local/share/zoxide/db.zo. Without a
named volume, the 'z <fragment>' jump targets are lost on every
'docker compose up --force-recreate'.
Add devbox-zoxide named volume in docker-compose.yml and
docker-compose.shared.yml, add ~/.local/share/zoxide to the
entrypoint ownership-fix loop per AGENTS.md convention, and update
the data-persistence tables in README.md and DOCKER_HUB.md.
Two changes that address a longstanding frustration: bash history is
lost on every container recreate, and the container's ~/.bashrc and
~/.inputrc are stock Debian (no history tuning, no prefix search on
arrow keys, no integrations).
Added a named volume 'devbox-shell-history' mounted at ~/.cache/bash
with HISTFILE pointing there; history now survives 'docker compose up
--force-recreate'. The volume is added to both docker-compose.yml and
docker-compose.shared.yml, and ~/.cache/bash is registered in the
entrypoint ownership-fix loop per the AGENTS.md convention.
Baked rootfs/home/developer/.bash_aliases (sourced automatically by
Debian's default ~/.bashrc) and rootfs/home/developer/.inputrc into
the image. They give new containers: 100k-entry timestamped dedup
history with per-prompt flush, Up/Down arrow prefix history search,
case-insensitive coloured completion, aliases that prefer eza and
bat when present, git shortcuts, interactive rm/mv/cp, zoxide and
fzf (via 'fzf --bash') integration, and a [devbox] prompt marker.
The fzf integration uses 'fzf --bash' because we install fzf from
GitHub releases, not apt — the apt-path key-bindings aren't present.
Users who prefer their host's own shell config can uncomment two
commented bind-mount lines in docker-compose.yml to shadow the
baked defaults.
The auto-detection block was gated on UID mismatch alone: if the host
user already had UID 1000 (the container's default) but a non-default
GID, the GID was never adopted. That left host-written files with a
numeric GID the container couldn't resolve to a name (e.g. '1001' on
Debian VMs where useradd assigns a dedicated group starting at 1001).
Split UID and GID detection into independent conditions. Each dimension
is adopted from /workspace if its env var is unset and the workspace
value differs from the container default, regardless of the other
dimension's state. Preserves existing USER_UID / USER_GID overrides.
When a named volume is mounted at a nested path like
/home/developer/.local/state/opencode, Docker creates the parent
directory (.local/state) as root:root. The existing chown loop only
fixed the leaf mount points, leaving parents unwritable by the
developer user.
Add a non-recursive pre-pass that fixes ownership of the common
parent dirs (.local, .local/share, .local/state, .config) so that
anything creating new subdirs beneath them works correctly after a
fresh container recreate. Regression introduced by commit 967ce7d
(devbox-state volume) and only partially addressed by a06dc5f.
Named Docker volumes are created as root on first use, causing permission
denied errors for the developer user. The entrypoint now fixes ownership
of all known volume mount points after UID/GID adjustment.
