Stay up to date with practical insights on backend engineering, system design, and building reliable software.
Denmark has six million people. Maybe a few thousand of them are senior backend engineers. You need one, and so does everyone else.
Read moredepends_on controls container start order, not service readiness. Without health checks and explicit conditions, your app container starts before its dependencies are ready to accept connections — and your logs are full of startup errors that disappear on the second attempt.
