creating docker containers for each trainee

1. create an AWS instance (currently 4GB RAM, small CPU, use a free version of AWS Linux, which is rpm based) add/choose your ssh key while creating the instance
2. login (as ec2-user) and install docker

  # sudo yum update # not needed for a freshly installed instance
  sudo yum install docker
  sudo usermod -a -G docker ec2-user
  newgrp docker # get the docker group without logout/login
  sudo systemctl enable docker.service
  sudo systemctl start docker.service
  # test if it worked
  docker info

1. in a local shell
   copy the container folder into the aws instance

  cd .../fun-with-the-shell/
  scp -r container ec2-user@aws-hostname:

1. create the image from the dockerfile on the instance
   so grab the shell in the aws container again

  cd container
  docker build -t shell-training .

if an error ocurrs like "... public key not correct ..." while doing the dnf command then delete the almalinux image with docker image rm almalinux

1. start all instances with the script container/start-containers.sh be sure to check the script has line 6 commented out or nothing will happen
2. add a rule to alloe incoming access to the ports 2021-2036 under the point security groups
