Install Docker & Docker Compose - Centos 7

Step 1 — Install Docker

Install needed packages:

$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2

Configure the docker-ce repo:

$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Install docker-ce:

$ sudo yum install docker-ce

Add your user to the docker group with the following command.

$ sudo usermod -aG docker $(whoami)

Set Docker to start automatically at boot time:

$ sudo systemctl enable docker.service

Finally, start the Docker service:

$ sudo systemctl start docker.service

Step 2 — Install Docker Compose

Install Extra Packages for Enterprise Linux

$ sudo yum install epel-release

Install python-pip

$ sudo yum install -y python-pip

Then install Docker Compose:

You will also need to upgrade your Python packages on CentOS 7 to get docker-compose to run successfully:

$ sudo yum upgrade python*

To verify a successful Docker Compose installation, run:

$ docker-compose version
