To install Docker you will need to do those steps with sudo or login as root user with sudo -i
Create a Unix user for holding your application
groupadd app
useradd -d /home/app -s `which bash` -g app -m app
First, update your existing list of packages:
apt update
Next, install a few prerequisite packages which let apt use packages over HTTPS:
apt install apt-transport-https ca-certificates curl software-properties-common
Then add the GPG key for the official Docker repository to your system:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
Add the Docker repository to APT sources:
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"
Next, update the package database with the Docker packages from the newly added repo:
apt update
Make sure you are about to install from the Docker repo instead of the default Ubuntu repo:
Finally, install Docker:
apt install docker-ce
Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it's running:
systemctl status docker
Add your app user into the docker group
usermod -aG docker app
Run this command to download the latest version of Docker Compose:
curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
Login to your app user:
su - app
