Kubernetes the hard way with vagrant

You can study kubernetes with vagrant. Credits go to the Kinvolk team because this repository is based on https://github.com/kinvolk/kubernetes-the-hard-way-vagrant .

Differences with the Kinvolk version atm

• Uses containerd
• Uses gVisor
• The pod-cidr is the same as the tutorial ( 10.200.${i}.0/24 )

How to use this repository

• Hit vagrant up to bring up the vms (1 load balancer node, 3 controllers nodes , 3 worker nodes)
• Use the workspace directory to follow Kelsey Hightower's repository https://github.com/kelseyhightower/kubernetes-the-hard-way
• A few things to care about is
  • gcloud commands won't work (of course). Skip everything related to gcloud or use an alternative command. Have a look at the scripts directory if you get stuck. They correspond with the chapters.
  • EXTERNAL_IP , KUBERNETES_PUBLIC_ADDRESS would be 10.240.0.40 (the load balancer's ip)
  • vagrant-scp would come in handy for scp commands
  • Careful about INTERNAL_IPs and POD_CIDR because you cannot fetch them with gcloud commands.
  • Be sure to add the [plugins.cri] config and stream_server_address setting to the containerd's config.toml. If you miss this, you won't be able to exec in to the container. Have a look at the script .
• vagrant destroy -f when you finish and clean up the workspace .

All the scripts inside the scripts directory correspond to the commands and chapters mentioned in the tutorial. It uses alternative commands which correspond to gcloud commands. This has been tested with this version of the tutorial.
