Install required packages. yum-utils provides the yum-config-manager utility, and device-mapper-persistent-data and lvm2 are required by the devicemapper storage driver.

$ sudo yum install -y yum-utils \
device-mapper-persistent-data \
lvm2

Use the following command to set up the stable repository. You always need the stable repository, even if you want to install builds from the edge or test repositories as well.

$ sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo

Optional: Enable the edge and test repositories. These repositories are included in the docker.repo file above but are disabled by default. You can enable them alongside the stable repository.

$ sudo yum-config-manager --enable docker-ce-edge
$ sudo yum-config-manager --enable docker-ce-test

You can disable the edge or test repository by running the yum-config-manager command with the --disable flag. To re-enable it, use the --enable flag. The following command disables the edge repository.

$ sudo yum-config-manager --disable docker-ce-edge
Note: Starting with Docker 17.06, stable releases are also pushed to the edge and test repositories.

Learn about stable and edge builds.

INSTALL DOCKER CE
Install the latest version of Docker CE, or go to the next step to install a specific version:

$ sudo yum install docker-ce

To install a specific version of Docker CE, list the available versions in the repo, then select and install:

a. List and sort the versions available in your repo. This example sorts results by version number, highest to lowest, and is truncated:

$ yum list docker-ce --showduplicates | sort -r

docker-ce.x86_64 18.09.0.ce-1.el7.centos docker-ce-stable
The list returned depends on which repositories are enabled, and is specific to your version of CentOS (indicated by the .el7 suffix in this example).

b. Install a specific version by its fully qualified package name, which is the package name (docker-ce) plus the version string (2nd column) up to the first hyphen, separated by a hyphen (-), for example, docker-ce-18.03.0.ce.

$ sudo yum install docker-ce-
Docker is installed but not started. The docker group is created, but no users are added to the group.
