Gazelle Extras
Docker Cloud Backup
- Listens to Docker Cloud events via the socket API
- When a service or stackfile is updated, create a backup in a versioned S3 bucket
Docker versions your app, but not its config.
Gazelle Deploy
- In slack: gz deploy env app tag
-
Bot starts deploy
- Find all env-app-* services
- Update image to gazelle/app:tag
- Deploy env-app-migrate if present and waits for it to exit successfully
-
Deploy env-app-web
- If env-app-web-green or env-app-web-blue, automatically does a blue green deploy
- Deploy other env-app-*
- If anything fails, rolls back to previous version
Docker deploys processes, not applications.
