sample-operator

Base sample for a custom controller in Kubernetes working with custom resources. Operator=CRD+CustomController

Thanks: kubernetes/sample-controller resouer/k8s-controller-custom-resource

Code generator

• create CRD(custom resource definitions)
• copy code-generator hack folder and script file, and modify script file for yourself
• go mod vendor
• Execute under the sample-operator folder: ./hack/update-codegen.sh

Build&Run

# Clone repo
$ git clone https://github.com/aaronmegs/sample-operator
$ cd sample-operator
# Build
$ go build -o samplecrd-operator .
$ ./samplecrd-operator -kubeconfig=$HOME/.kube/config -alsologtostderr=true

Usage

You should create the CRD of Foo and Network first:

$ kubectl apply -f artifacts/example/crd-foo.yaml
$ kubectl apply -f artifacts/example/crd-network.yaml

You can then trigger an event by creating a Foo or Network API instance:

$ kubectl apply -f artifacts/example/example-foo.yaml
$ kubectl apply -f artifacts/example/example-network.yaml

CURD the Foo and Network API instance, and check the logs of controller.

Enjoy!
