WIGM

WIGM is a sample project that is designed to help users understand why operators are useful. The project provides folders for 4 different deployment methods:

• yaml
• helm
• metacontroller
• operator-sdk

Operator Demo

Start the cluster

• cd wigm-operator-sdk
• ./start-and-watch.sh
  • Bootstraps a Kubernetes cluster with docker-compose using k3s
  • Configures it for the demo
  • Watches applicable resources

After the cluster has started. There will be a kubeconfig.yaml file in the current directory. kubectl can be used on the user's machine to access the demo cluster at any time by passing a flag (kubectl --kubeconfig=kubeconfig.yaml) or exporting an environment variable (export KUBECONFIG=./kubeconfig.yaml).

Run Demo: demo.sh

An automatic demo script which walks the user through a few WIGM deployments with the demo architecture

Cleanup: cleanup.sh

Brings down the docker resources and cleans up the docker volumes. NOTE: This deletes all cluster state
