Docker is a powerful tool for creating, deploying, and managing containers. Commands cover a wide range of Docker functionalities, allowing you to build, run, manage, and distribute containers and images effectively.

Once you have a shell session inside the container, you can use any command-line text editor available within the container. Common editors include vi, vim, nano, or emacs. If the container doesn't have a text editor installed, you may need to install one before proceeding.

GoCD containers run as non-root user, by default. The Dockerized GoCD application will run as go:root (uid:1000, gid:0) user instead of running as root:root (uid:0, gid:0). Lets see the steps to run the Docker containers with gocd.

Font scaling based on the size of the container is a technique used to adjust the size of text within a container or element to make it more readable and visually appealing.

Mounting host volumes into Docker containers during build time is not recommended because the host files are not yet available during the build process. However, you can specify a volume in your Dockerfile and then mount the volume when you run the container.

To restart a single container with Docker Compose, you can use the 'restart' command:

To enter a Docker container that is already running with a TTY, you can use the "docker exec" command with the "-it" flags. The "-i" flag allows you to interact with the container's STDIN, and the "-t" flag allocates a TTY for the container.
