Here are the steps of installing Docker CE installation on Oracle Linux 7. Then we will pull docker official image of Node.js.
(1) Install the prerequisites
yum install -y yum-utils device-mapper-persistent-data lvm2
(2) Setup the stable repository
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
(3) Install Docker CE
yum install docker-ce docker-ce-cli containerd.io
(4) Start docker service and make it auto starting
systemctl start docker systemctl enable docker
(5) Verify that it is working
docker run hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 1b930d010525: Pull complete Digest: sha256:2557e3c07ed1e38f26e389462d03ed943586f744621577a99efb77324b0fe535 Status: Downloaded newer image for hello-world:latest Hello 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. (amd64) 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 bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
(6) Pull the official Node.js image on docker
docker pull node
(7) List the docker images
docker image list REPOSITORY TAG IMAGE ID CREATED SIZE node latest a0d7a409d125 37 hours ago 904MB hello-world latest fce289e99eb9 2 months ago 1.84kB
I hope it helps someone.
