k8s-sharedinformer

Simple example of the client-go SharedInformer that can be used to do all kinds of fun stuff with K8S deployment events

To run the example

1. Clone this repo - git clone https://github.com/venkyvb/k8s-sharedinformer.git
2. cd k8s-sharedinformer
3. Update the path to the KUBECONFIG file (assumes that this app is running outside the cluster)
4. Do a local K8S cluster set-up either using the Docker Desktop or the much more lightweight and awesome Kind
5. To update the go-mod dependencies run go get
6. Run the app - go run main.go.
7. In another terminal session run do a simple K8S deployment (the file nginx.yaml) - kubectl apply -f nginx.yaml
8. You would be able to see the message - Pod started -> nginx-deployment-XXXXXXXXX-XXXXX in the waiting console session created in step (6)
9. Now run kubectl delete deployment nginx-deployment in the 2nd terminal session
10. 8. You would be able to see the message - Pod deleted -> nginx-deployment-XXXXXXXXX-XXXXX in the waiting console session created in step (6)

Have fun !!
