warkanum 029b9cee2e feat(cmd): add installall/uninstallall; fix startall/stopall and service lifecycle
- startall now uses systemctl start (not enable --now)
- stopall now uses systemctl stop (not disable --now)
- add installall command (bulk install with --dry-run support)
- add uninstallall command (bulk disable+remove in reverse order)
- fix docker ExecStart to use -a flag so the process stays attached
- prefix ExecStop with - so a stop-on-already-dead container does not fail the unit

## Project Overview
**Unitdore** is a Go CLI tool that bridges container runtimes (Podman, Docker) and systemd. It discovers running containers, stores them in a YAML config, and generates + manages systemd `.service` unit files for each one.
# Agent Rules
Keep answers short. Question everything, never assume or guess. Ask if unsure.
You must use the AMCS MCP system tools. Set **unitdore** as the active project and always capture summaries of what was done as thoughts using the `capture_thought` tool. If AMCS is not available, write files to `docs/llm/log/yyyymmdd_hh.md`.
# Tools to use
When writing Go: `doc/tools/go-skill.md` (if present), otherwise follow standard Go conventions.
## Commands
```bash
make build # Compile binary: ./unitdore
make install # Install binary to /usr/bin, man page, create /etc/unitdore
make uninstall # Remove binary and man page
make test # go test ./... -v
make test-short # go test ./...
make lint # go vet ./...
make clean # Remove built binary
make release-version # Bump patch version, commit, tag, and push
```
## Architecture
```
cmd/ # Cobra commands (edit, install, list, root, start, startall,
# status, stop, stopall, syncup, uninstall, update)
config/ # Config struct + YAML load/save (units.yaml)
runtime/ # Docker and Podman runtime abstraction
systemd/ # .service file generator and systemd manager
docs/ # generated-units.md (unit file examples), unitdore.1 (man page)
```
### Key packages
- **`config`** — `Unit` and `Config` structs; `Load`, `Save`, `FindUnit`, `AddUnit`
- **`runtime`** — `ContainerRuntime` interface; `docker.go`, `podman.go` implementations
- **`systemd`** — `generator.go` builds `.service` file content; `manager.go` calls `systemctl`
### Config file
**Location:** `/etc/unitdore/units.yaml`
```yaml
prefix: "" # prepended to service file name (e.g. "prod-")
suffix: "" # appended to service file name (e.g. "-svc")
units:
- name: nginx
runtime: podman # podman | docker
user: "" # empty = system unit; set for rootless user unit
command: "" # override ExecStart entirely
order: 1 # startup order, lower = earlier; same = parallel
delay: 0s # delay after previous order group
enabled: true
disabled_reason: "" # auto-set by syncup reconciliation
restart: false # Restart=on-failure
restart_sec: 0 # RestartSec
restart_retries: 0 # StartLimitBurst
```
### Generated service file locations
| Scenario | Path |
|---|---|
| System unit (root) | `/etc/systemd/system/unitdore-<name>.service` |
| User unit | `/home/<user>/.config/systemd/user/unitdore-<name>.service` |
| With prefix `prod-` | `/etc/systemd/system/unitdore-prod-<name>.service` |
| With suffix `-svc` | `/etc/systemd/system/unitdore-<name>-svc.service` |
### Libraries
- `github.com/spf13/cobra` — CLI framework
- `gopkg.in/yaml.v3` — config parsing
## Testing
Tests exist in:
- `config/config_test.go`
- `runtime/runtime_test.go`
- `systemd/generator_test.go`
Always run `make test` before marking a task complete. Add tests for new behaviour in the same package as the code under test.
## Additional documentation
- `docs/generated-units.md` — full annotated examples of every generated unit file combination
- `docs/unitdore.1` — man page

- Generating and improving documentation
- Writing and enhancing tests
- Refactoring and optimizing existing code
AI is **not** used for core design or architecture decisions.
All design decisions are deferred to human discussion.
AI is employed only for enhancements to human-written code.
We are aware of significant AI hallucinations; all AI-generated content is to be reviewed and verified by humans.
