To install Docker, you need the 64-bit version of CentOS 7.
2、Uninstall old versions
Older versions of Docker were called docker or docker-engine. If these are installed, uninstall them, along with associated dependencies.$ sudo yum remove docker \
docker-common container-selinux docker-selinux docker-engine
(1) Install yum-utils, which provides the yum-config-manager utility:
$ sudo yum install -y yum-utils
(2) Use the following command to set up the stable repository. You always need the stablerepository, even if you want to install edge builds as well.
$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo(3) Optional: Enable the edge repository. This repository is included in the docker.repo file above but is disabled by default. You can enable it alongside the stable repository.
$ sudo yum-config-manager --enable docker-ce-edge
(1) Update the yum package index.
$ sudo yum makecache fast(2) Install the latest version of Docker, or go to the next step to install a specific version.
| Docker Edition | Command |
|---|---|
| Docker CE | sudo yum install docker-ce |
| Docker EE | sudo yum install docker-ee |
(3) On production systems, you should install a specific version of Docker instead of always using the latest. List the available versions. This example uses the sort -r command to sort the results by version number, highest to lowest, and is truncated.
yum list docker-ce.x86_64 --showduplicates |sort -r
(4) Start Docker.
sudo systemctl start docker(5) Verify that docker is installed correctly by running the hello-world image.
$ sudo docker run hello-world
