# Changelog

## 2026-07-19

### Standalone installation and deployment

- Added `rsmon-worker install` for installing the current binary, a mode-0600
  environment file, and a root-owned systemd service.
- Added `rsmon-worker deploy` for installing workers over SSH with key or
  password authentication, optional secret files, and host-key verification
  through `known_hosts` or a pinned fingerprint.
- Added `--token-file`, `--url`, `--api-key`, and `--no-start` deployment
  options.
- Added optional `--docker` deployment using the prebuilt
  `reg.rsxx.ru/rsmon/rsmon-worker:latest` image. Remote Docker deployment pulls
  the image on the target host and does not depend on the local architecture.
- Simplified the default systemd service to `Type=simple`, `User=root`, and
  `Restart=on-failure`.
- Reworked the legacy `scripts/install-systemd.sh` script as a compatibility
  wrapper around the built-in installer.

### Standalone repository cleanup

- Removed the remaining certificate-bundle fallback under `/data/rsmon` and
  updated its documentation.
- Changed Docker build and runtime bases to public Go and Debian images.
- Documented binary, systemd, Docker, and SSH deployment workflows.
- Added installer and SSH host-verification tests.

### Verification

- Passed `make test`, `make build`, `go vet`, and `go mod verify`.
- Validated systemd units, Compose configuration, Docker image pull and
  execution, and production worker job reporting.
- Published the changes as commit `3256dcd` (`feat: add worker install and
  deploy`) on `master`, triggering the Docker image workflow.
