Ports Mapping vs Public Port

Ports Mapping

Ports mapping is using the Docker port mapping feature. It is used to map the container port to the host port. For example, if you set the port mapping to 8080:80, the container port 80 will be mapped to the host port 8080.

Public Port

Public port is used to expose the container port to the internet, by starting an Nginx TCP proxy.

Which one should I use?

  • Port mappings makes the connection/port permanent (you need to restart your database to change it).
  • The public port makes the connection/port dynamic (you can change it without restarting the database, Coolify will restart the Nginx TCP proxy for you).
