# To set up an Ubuntu system like we need for this workshop,
# copy this script the the target system:
#    wget https://raw.githubusercontent.com/OtherDevOpsGene/intro-to-docker/main/install-docker.sh
# and run it as root:
#    sudo bash ./install-docker.sh

# You'll also need the following ports open:
# * 22 for SSH traffic if the system is in the cloud
# * 80, 4444, and 8080 open for HTTP traffic
