 - **Run User**: keep it as default value `git` because `start.sh` already setup a user with name `git`.

 - **SSH Port**: Use the exposed port from Docker container. For example, your SSH server listens on `22` inside Docker, but you expose it by `10022:22`, then use `10022` for this value. **Builtin SSH server is not recommended inside Docker Container**
 - **HTTP Port**: Use port you want Gogs to listen on inside Docker container. For example, your Gogs listens on `3000` inside Docker, and you expose it by `10080:3000`, but you still use `3000` for this value.
