It also creates a docker group, however, it doesn't add any users to the group by default.\n\nTo install a specific version, start by listing the available versions in the repository\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ dnf list docker-ce --showduplicates | sort -r\n\n   docker-ce.x86_64    3:{{% param \"docker_ce_version\" %}}-1.el9    docker-ce-stable\n   docker-ce.x86_64    3:{{% param \"docker_ce_version_prev\" %}}-1.el9    docker-ce-stable\n   <...>\n```\n\nThe list returned depends on which repositories are enabled, and is specific to your version of CentOS (indicated by the .el9 suffix in this example).\n\nInstall a specific version by its fully qualified package name, which is the package name (docker-ce) plus the version string (2nd column), separated by a hyphen (-). For example, docker-ce-3:-1.el9.\n\nReplace with the desired version and then run the following command to install\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ sudo dnf install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io docker-buildx-plugin docker-compose-plugin\n```\n\nThis command installs Docker, but it doesn't start Docker. It also creates a docker group, however, it doesn't add any users to the group by default.\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ sudo systemctl enable --now docker\n```\n\nThis configures the Docker systemd service to start automatically when you boot your system. If you don't want Docker to start automatically, use sudo systemctl start docker instead.\n\nVerify that the installation is successful by running the hello-world image\n\nBounded code example (external data; do not execute automatically):\n```console\n   $ sudo docker run hello-world\n```\n\nThis command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits. …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
