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

Each folder contains the following common files:

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).

demo.sh

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

cleanup.sh

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

Try It Out

Run a test cluster and demo for any deployment method

1. cd METHODFOLDER
2. ./start-and-watch.sh
3. In a new terminal: ./demo.sh
4. Optional: Run extra kubectl commands against the demo cluster if desired
5. Optional: ./cleanup.sh
