Instalando Docker no CentOS7

Sem muita enrolação:

[root@manager ~]# yum -y update
[root@manager ~]# yum install yum-utils –y
[root@manager ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
[root@manager ~]# yum install docker-ce docker-ce-cli containerd.io –y
[root@manager ~]# systemctl start docker
[root@manager ~]# systemctl enable docker
