What are the differences between Docker environment variables and config files?

What are the differences between Docker environment variables and config files?

Docker environment variables are used to pass configuration data to containers at runtime, while config files are used to store configuration data in a file format that can be read by the application.

When should I use environment variables instead of config files?

Use environment variables for sensitive data or when you need to change configurations frequently. Config files are better for static configurations.

Can I use both in the same Docker container?

Yes, you can use both environment variables and config files in the same container. They can complement each other.

What are some best practices for managing these configurations?

Best practices include keeping sensitive data in environment variables, using version control for config files, and documenting your configurations.
