Motivation

This project is created to build a sample of a kubernetes controller and understand what's under the hood.
This kubernetes controller sample helped me so much 🙏.

Development

Tools

k8s.io/code-generator: generate deepcopy, clientset, informers and listers of the team CRD
ko: build and deploy controller in the kubernetes cluster

Run teams controller

Run controller locally:

go run ./cmd/controller -kubeconfig ~/.kube/config -v 5

Run within a kubernetes cluster using ko:

# login to dockerhub
docker login
export KO_DOCKER_REPO=ftahmed

# build & deploy using ko
ko apply -f config/

Generate code

Command for generating deepcopy, clientset, infromers and listers of the team resource

go mod vendor
./hack/update-codegen.sh

Run tests

go test -v ./...
