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 docker.

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