Add to Docker Group (may need to run twice in automation):
# Create the Docker group
sudo groupadd docker
# Add your user to the Docker group
sudo usermod -aG docker $USER
# Log out and log back in to apply the group changes
# Alternatively, use the following command to apply the new group membership without logging out and back in
newgrp docker
# Verify that your user is added to the Docker group
