Docker
Install Docker.
Docker is installed from packages available in Docker's CE Stable package repository. For Centos, the centos-extra repository must be enabled. For Red Hat, centos-extra needs to be also added, including Centos GPG key. These dependencies are not included in this role. The latest docker version found in the repository is installed unless it is overridden with docker_version. Same version will be installed for docker engine and docker cli.
User namespaces can be optionally activated with variable docker_user_namespace (default is no). This might require regenerating the GRUB configuration and in turn restarting the server. A standard dorremap user will also be added to /etc/subuid and /etc/subgid.
A list of environment variables can be added to Docker's systemd service using docker_env.
Requirements
See meta/main.yml.
Role Variables
