Docker-101 Part-2 which would enable you to install and validate the Docker community edition on your machine and in next Part we would be covering the Docker CLI commands for you to begin using various Docker commands.
Prepare your Docker environment
In this tutorial, we would begin by installing Docker CE(Community Edition) on MAC OS.
To begin with installation, we would need CentOS 7 with
centos-extras repo enabled.
Following commands would install the Docker CE on your Linux machine.
Note: We would be installing the latest release of Docker CE. In-case you are looking to install specific release please refer here
#setup the repository $ 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 #Installing the Docker CE $ sudo yum install docker-ce docker-ce-cli containerd.io #Start Docker Daemon $ sudo systemctl start docker
Validate your Docker Setup
Once the installation is done you can validate your Docker setup by following commands.
Verify that Docker CE is installed correctly by running the
$ sudo docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world ca4f61b1923c: Pull complete Digest: sha256:ca0eeb6fb05351dfc8759c20733c91def84cb8007aa89a5bf606bc8b315b9fc7 Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. ...
docker --version and ensure that you have a supported version of Docker:
$ docker --version Docker version 17.12.0-ce, build c97c6d6
Note: Docker Build number may be different based on the latest available build of Docker CE.
docker info to view even more details about your docker installation:
$ docker info Containers: 0 Running: 0 Paused: 0 Stopped: 0 Images: 0 Server Version: 17.12.0-ce Storage Driver: overlay2 ...
This concludes our this week’s series of Docker-101 Part-2, after which you should now have a running docker environment available in your Laptop/PC/Server/Virtual Machine.
