Sometimes you just want to get a pat on the back after you deploy something awesome.
I wrote this operator to present to the UT Rust meetup in 2023. Feel free to use this as a refernce but know that I do not plan to keep this up to date.
First, load the SuperKudo CRD into your cluster and list your crds to make sure it registered successfully.
$ kubectl apply -f superkudos.kudoz.desh.es.yaml
customresourcedefinition.apiextensions.k8s.io/superkudos.kudoz.desh.es configured
$ kubectl get crds
NAME CREATED AT
...
superkudos.kudoz.desh.es 2023-07-14T00:04:38Z
Next, load the example SuperKudo resource into your cluster in the default namespace.
$ cat superkudo.example.yaml
kind: SuperKudo
apiVersion: kudoz.desh.es/v1
metadata:
name: super-fun-example
namespace: default
spec:
selector:
labels:
app: nginx
deliverTo:
slack: http://localhost:8000/test/my/hook
$ kubectl apply -f superkudo.example.yaml
superkudo.kudoz.desh.es/super-fun-example created
Then, make sure you have a deployment that matches the labels app: nginx. There is an example one in the fixtures/ directory.
$ kubectl apply -f fixtures/deployment.example.yaml
deployment.apps/nginx-deployment-example created
And finally, start the kudoz operator. In the output below I swapped the .spec.deliverTo.slack URL to a real one. The above is totally fine for testing, though.
$ cargo run
Finished dev [unoptimized + debuginfo] target(s) in 0.35s
Running `target/debug/kudoz-controller`
Sending a kudo to Some("super-fun-demo") because Some("nginx-deployment-example") finished deploying!
reconciled (ObjectRef { dyntype: (), name: "super-fun-demo", namespace: Some("default"), extra: Extra { resource_version: Some("1787"), uid: Some("6a36a7dc-441e-4904-ba1c-8eb0873f0c9d") } }, Action { requeue_after: None })
Nice! Looked like it all worked!
