Installing and Configuring the Docker Engine

Make sure old versions of Docker are not present on the system:

sudo apt-get remove docker docker-engine docker.io containerd runc

Update the apt package index and install the packages needed for apt to use a repository over HTTPS:

sudo apt update -y
sudo apt install -y ca-certificates curl gnupg

Add the official Docker GPG key.

Set up the repository.

Install Docker packages.

Verify that your installation is working.

Make sure the docker group was created:

sudo groupadd docker

Add your user to the docker group:

sudo usermod -aG docker $USER

Either log out and back in as the cloud_user, or run this command:

newgrp docker

After logging back in or executing the mentioned command, verify the access for the cloud_user.

Edit daemon.json:

sudo vi /etc/docker/daemon.json

Add configuration to daemon.json to set the default logging driver:

{
  "log-driver": "syslog"
}

Restart Docker:

sudo systemctl restart docker

Verify that the logging driver was set properly:

docker info | grep Logging

This command should return a line that says:

Logging Driver: syslog

Additionally, you can configure Docker to start on boot.
