- Moving to 2-hour segments
- First five minutes covering goals for session
- Last five minutes wrapping up and summarizing
- Why I don’t use/like Docker compose (look into Kompose)
- I went through a moment of Podman (because of
systemd)
- We need a “host container” image (Dockerfile)
- Overview of
kubeadm init phase --help for help
- Start of Dockerfile
- Use of
run shortcut command
- Discovered that
apt-key is deprecated and will be removed
- Instead copy keys directly to
/etc/apt/trusted.gpg.d
- Always use
apt-get in scripts (RTFM to know why)
- Install
systemd and set ENTRYPOINT
- Symlink
/bin/init to /usr/bin/systemd
- Still kinks to work out
