Upgrade docker to version 18 on Centos

For stability love I was sticking to docker 1.12....
Several new features are interesting, so I am upgrading...
This link https://docs.docker.com/install/linux/docker-ce/centos/#set-up-the-repository
is really useful

This is what I have done:

docker version
sudo yum remove docker docker-common docker-selinux docker-engine
sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum-config-manager --enable docker-ce-edge
sudo yum-config-manager --enable docker-ce-test
sudo yum install docker-ce
docker version

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?



oops I forgot to start and enable:

sudo systemctl start docker
sudo systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
