Debugging a Mysterious Docker Issue

I recently encountered a weird issue with my Docker container where it would start, run for a few seconds, and then exit with a non-zero status code.

I checked the logs, but there were no obvious errors.

I spent hours trying to figure out what was going on, trying different Docker commands and searching online for solutions.

It wasn't until I used the 'docker logs -f' command to view the container's logs in real-time that I saw the issue.

The problem was that my container was trying to connect to a database that wasn't available yet.

I realized that I needed to add a dependency to my Docker Compose file to ensure that the database was up and running before my container started.

The fix was simple, but it took me a while to get there.

Has anyone else ever encountered a similar issue? What was your solution?
