• Docker

Overview

Verified with Centos 7.

Prerequisites

A 3.8 kernel or later is required.

RedHat/Centos

Setting a yum Repository

Create a docker.repo in /etc/yum.repos.d:

[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg

Alternative URL for Centos 6: https://yum.dockerproject.org/repo/main/centos/6 Oracle Linux: https://yum.dockerproject.org/repo/main/oraclelinux/6/

This is an example of how to use an "entitled" RH repository:

Using yum with registry.access.redhat.com Images

Remove Older Releases

Remove older Docker releases,

yum list installed | grep docker

yum erase ...

Install

yum install docker-engine

systemctl is-enabled docker
enabled

If not, enable it:

systemctl enable docker

Reboot
