Installation of Docker on Alpine Linux

To install Docker on Alpine Linux, follow these steps:

1. To install Docker on Alpine Linux, run apk add --update docker openrc.

   Important

   The Docker package is available in the Community repository. Therefore, if apk add fails because of unsatisfiable constraints error, you need to edit the /etc/apk/repositories file to add (or uncomment) a line. Community repository link: http://dl-cdn.alpinelinux.org/alpine/latest-stable/community.

2. To start the Docker daemon at boot, run rc-update add docker boot.
3. To start the Docker daemon manually, run service docker start.
4. Execute service docker status to ensure the status is running.
