Installing Docker in CentOS 7

Error while installing docker in CentOS7

Remove podman and buildah

If you face the above mentioned problem, then remove them first. Read here​

The podman and buildah packages conflict with docker-ce. Remove them first:

sudo yum erase podman buildah

And you can then install docker-ce:

yum install docker-ce

Install Docker

sudo yum check-update
curl -fsSL https://get.docker.com/ | sh
sudo usermod -aG docker $(whoami) # If you want to avoid typing sudo whenever you run the docker command, add your username to the docker group
sudo systemctl start docker # start docker after the installation
sudo systemctl status docker # Check status
sudo systemctl enable docker # Mak sure it starts at every server reboot
