- Install required packages
$ sudo yum install -y device-mapper-persistent-data lvm2
2. Add the Docker Community Edition repository:
sudo yum-config-manager \
3. Install Docker Community Edition and Containerd
$ sudo yum install -y docker-ce-18.09.5 docker-ce-cli-18.09.5 containerd.io
4. Add <user> to the docker group, giving the user permission to run the docker command without sudo
sudo usermod -a -G docker user
6. Login and test that works
$ docker run hello-world
If everything gone well it should return an output that looks like the bellow
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
0e03bdcc26d7: Pull complete
Status: Downloaded newer image for hello-world:latestHello from Docker!
This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID:
