Staging Migration: Software Dependencies for both Ubuntu and CentOS are missing two steps

[dwk2]

Issue description

1) When I setup my staging server for ISLE7, and add my user to the docker group, I get the following error message: "group 'docker' does not exist" 2) When I run docker ps -a, I get the following error message: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Additional details / screenshots

Solution would be to add the following to the Software Dependencies documentation page, for both the Ubuntu and CentOS sections

Create Step 3.5) Create the docker group sudo groupadd docker Create Step 5) Configure Docker to start on boot

 sudo systemctl enable docker.service
 sudo systemctl enable containerd.service

(Solutions from Post-installation steps for Linux)
