    • Immutable Infrastructures – CoreOS
      • CoreOS is a linux distribution that is completely described by YAML
      • Kubernetes – learnt a bit more about it by actually installing it (kubespray), also, trying to do it in an “air-gapped” environment proved hard work
      • kubespray works by bootstrapping python onto the CoreOS nodes so it can use ansible.
      • Doing Immutable Infrastructure with deb packages?
      • Docker
      • Terraform
