Update an existing systemd/LXC GREE Controller installation from this source tree.
|
|
|
|
Usage:
|
|
sudo ./scripts/update.sh
|
|
sudo ./scripts/update.sh --skip-tests
|
|
|
|
The updater:
|
|
1. builds and tests the new release while the old service is still running,
|
|
2. stops the service,
|
|
3. backs up the binary, systemd unit, environment file and SQLite database,
|
|
4. installs the new binary and unit,
|
|
5. restarts and checks /api/health,
|
|
6. rolls back the binary/unit/database automatically if startup fails.
