# 1 Check if Docker is already installed on your system
systemctl status docker
rpm -qa | grep -E "docker"
## 1.1 If you want to reinstall, you can uninstall the old version of Docker first
yum remove docker-ce
rm -rf /var/lib/docker
## 1.2 Update system packages yum -y update

# 2 Visit the following website and download the Docker RPM package# https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
# For example, wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.06.3.ce-3.el7.x86_64.rpm

# 3 Install yum install docker-ce-18.06.3.ce-3.el7.x86_64.rpm

# 4 Start systemctl start docker
