The sync command now performs both operations:
- Discovers running services and updates state.yaml
- Captures image digests and updates dockerfarm-log.toml
Removes the standalone snapshot command to keep the API simple.
The sync command queries all hosts to find where services are actually
running and updates the state file to match reality. Supports --dry-run
to preview changes without modifying state. Useful for initial setup
or after manual changes.
- up: Detects if service is deployed on a different host and
automatically runs down on the old host before up on the new
- down: Removes service from state tracking after successful stop
- Enables seamless service migration by just changing the config
Allows running compose commands on a specific host rather than
the configured host for a service. Used for migration when
stopping a service on the old host before starting on the new.
Tracks which host each service is deployed on in
~/.config/compose-farm/state.yaml. This enables automatic
migration when a service's host assignment changes.
- hello: Simple hello-world container for testing
- nginx: Nginx web server on port 8080
- sdc.yaml: Local config (no SSH needed)
- README with usage instructions
- Tests for config module (Host, Config, load_config)
- Tests for ssh module (local detection, command execution)
- 30 tests, all passing
- pytest-asyncio for async test support
When host address is 'local', 'localhost', '127.0.0.1', or '::1',
commands run locally via subprocess instead of SSH. This is useful
when running sdc from one of the target nodes.
