coxyz-cli 0.2.0

CLI to manage Docker services under /srv/docker (ownership, permissions, ACLs)

coxyz

CLI to manage Docker services under /srv/docker following coxyz rules (ownership, permissions, POSIX ACLs).

Replaces check_fix_permission.zsh + services.zsh with a single typed Python tool driven by a YAML configuration.

Install

coxyz is published on PyPI as the coxyz-cli package — the installed command stays coxyz. It needs root for most operations (chown / setfacl), so install it system-wide and run it with sudo.

sudo apt install -y pipx

# Install into an isolated venv under /opt, with the binary on the system PATH.
sudo env PIPX_HOME=/opt/pipx PIPX_BIN_DIR=/usr/local/bin pipx install coxyz-cli

With pipx ≥ 1.5 you can use the shorter sudo pipx install --global coxyz-cli instead. Debian 12 ships pipx 1.4.3, which needs the env form above.

Then run:

sudo coxyz check

Optionally enable shell completion for your user (no sudo):

coxyz --install-completion

Update

sudo env PIPX_HOME=/opt/pipx PIPX_BIN_DIR=/usr/local/bin pipx upgrade coxyz-cli

Migrating from a manual install

Earlier setups used hand-written coxyz / coxyz-update wrapper scripts and a venv in /usr/local/libexec/coxyz. Remove them before installing from PyPI:

sudo rm -f  /usr/local/bin/coxyz /usr/local/bin/coxyz-update
sudo rm -rf /usr/local/libexec/coxyz
rm -f ~/.zsh/completions/_coxyz ~/.zcompdump*   # stale completion artefacts

(/etc/coxyz/config.yaml is kept — it is your configuration, not part of the install.)

Configuration

coxyz reads, in order: --config FILE, /etc/coxyz/config.yaml, ~/.config/coxyz/config.yaml, then the bundled defaults.

coxyz show-config       # inspect the resolved config
sudo coxyz edit         # create/edit /etc/coxyz/config.yaml (seeded from defaults)

Example excludes in config.yaml:

exclude:
  - "*.bak"
  - "*/do_not_touch/"

Commands

coxyz list                      # list services with image, ports, status
coxyz list -C apps              # filter by category

coxyz check                     # audit all services (exit 1 on drift)
coxyz check bitwarden           # audit one service
coxyz check apps/bitwarden -v   # verbose (show OK findings too)

coxyz apply                     # preview planned fixes, confirm, then apply
coxyz apply bitwarden -y

coxyz create                    # interactive prompts
coxyz create -C apps -n myapp -i nginx:1.27 -p 80 --apply

coxyz show-config               # print resolved config
coxyz edit                      # edit /etc/coxyz/config.yaml

Most operations require root (chown / setfacl), so prefix with sudo.

How it works

• Config (/etc/coxyz/config.yaml or bundled default) defines:
  • root dir, ACL principals, authorized categories
  • exclude glob patterns to ignore paths during audit/apply
  • per-path rules: mode, ACL perms, optional owner override, audit-only flag
• check: read-only audit. Reports drift and warn-only (data/, .env).
• apply: shows planned changes, asks for confirmation, then applies fixes.
  • Touches: category/service dirs, compose.yaml, the config/ directory.
  • Never touches: data/ contents, .env files (audit-only).
  • Creates required missing directories before applying path fixes.
• create: scaffolds <category>/<service>/{compose.yaml,config/,data/} with correct owners + perms + ACL.
• list: parses each compose.yaml for image/ports and runs an audit to show a compliance status.

ACL handling

A path governed by an ACL rule is brought to compliance with a single setfacl --set call that writes the base entries (u::/g::/o::, i.e. the octal mode) and the named entries together. setfacl then recomputes the ACL mask as the union of the owning group and every named entry, so each entry stays fully effective — getfacl never shows an #effective: restriction.

coxyz deliberately never runs chmod on an ACL-managed path: a chmod after a setfacl would rewrite the mask instead of the group bits and silently shrink the effective rights of every named entry.

One consequence: when a named entry grants more than the owning group (e.g. a principal with rw on a 750 directory), the mask widens and ls -l shows the wider group digit (770). That is correct POSIX behaviour — the audit compares ACL entries, not the displayed mode.

File layout (enforced)

/srv/docker/<category>/<service>/
├── compose.yaml      660  svc_<cat>:svc_<cat>  + ACL principals
├── config/           750  svc_<cat>:svc_<cat>  + ACL principals
│   └── ...           (contents not audited)
└── data/             750  svc_<cat>:svc_<cat>  no ACL (audit only)

Development

make test       # run the test suite
make build      # build sdist + wheel into dist/
make release    # tag the current version and push (CI publishes to PyPI)

Releasing: bump __version__ in src/coxyz/__init__.py, commit, then make release. The tag vX.Y.Z triggers .github/workflows/publish.yml, which publishes to PyPI via Trusted Publishing.
