Goal

Docker is  #1 container industry conference for enterprise IT professionals, developers, architects and business leaders. Docker Community Edition (CE) is ideal for developers and small teams looking to get started with Docker and experimenting with container-based apps. It is one of the most important tools of DevOps engineer. Node.js is a JavaScript-based platform for server-side and networking applications.

Here are the steps of installing Docker CE installation on Oracle Linux 7. Then we will pull docker official image of Node.js.

 

Steps

(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

(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

 

Enjoy!

 

I hope it helps someone.
