install docker and docker compose

install-docker.sh

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 -y
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:

$ sudo pip 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

echo "Install needed packages"
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

echo "Configure the docker-ce repo"
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

echo "Install docker-ce"
sudo yum install docker-ce -y

echo "Add your user to the docker group with the following command"
sudo usermod -aG docker $(whoami)

echo "Set Docker to start automatically at boot time"
sudo systemctl enable docker.service

echo "Finally, start the Docker service"
sudo systemctl start docker.service
