Install Docker & Docker Compose

Centos 7

RedHat

Step 1 — Install Docker6

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 python3-pip
python3 -m pip install -U pip
python3 -m pip install -U setuptools

Install correct pip version

sudo apt-get remove --purge python-pip
sudo apt-get autoremove
sudo rm -f /usr/local/bin/pip
sudo easy_install pip==20.3.4
pip --version

Then install Docker Compose:

sudo pip3 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

Mint

sudo apt-get update

sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

Next add Docker official key which is important in enabling Docker repo.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Adding Docker repository

Next thing is to add Docker repository to Linux Mint. The variable ‘$ (. /etc/os-release; echo “$ubuntu-codename”)’ ensures that you are using the right distribution of your Linux Mint

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(. /etc/os-release; echo "$UBUNTU_CODENAME") stable"

Update your system again

sudo apt-get update

sudo apt-get -y install docker-ce docker-ce-cli containerd.io

sudo usermod -aG docker $USER
newgrp docker
