How to do zero-downtime deployment
Health checks, backward-compatible migrations and a rollback plan for releasing a new version without users noticing.
Not every project needs a managed platform. If you run several projects on one server, Coolify brings HTTPS and automated deployment into one panel.
Define it with Docker Compose
Defining the application, database and persistent volumes in a Compose file documents the environment as code. Secrets go in the panel’s environment variables, not the repository.
Take health checks seriously
A health check should prove the database is reachable, not only that the process is up. Otherwise a broken release looks healthy.
Test backups by restoring them
Taking a backup is half the job. You cannot know it works until you regularly restore it to an empty environment.
