Lab 3.1 Useless instructions


After completing the LAB 3.1, I found that there is some useless instruction :

  • The installation of the docker key (root@cp: ̃# curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -) We don't use the docker apt repo so we don't need this key
  • The sudo with the last command is useless, I have the same results by running the command as a regular user (sudo kubeadm config print init-defaults)

Best regards,


  • Also, we should not be using apt-key anymore since it's deprecated. The man page explains the new method.
