How do I troubleshoot my Docker deployment issues?

I'm having trouble deploying my application with Docker. What should I check first?

First, check your Docker logs for any error messages. You can use the command docker logs <container_id>.

I checked the logs, and it says 'port already in use'. What does that mean?

It means another application is using the same port that your Docker container is trying to bind to. You can either stop that application or change the port in your Docker configuration.

How do I change the port in my Docker configuration?

You can change the port in your docker-compose.yml file or in the docker run command by using the -p option to specify a different port.
