yanet-operator
Yanet Operator:
- monitoring new and changes of existing yanet/yanet-config crds.
- create Deployment based on data from yanet crd spec(only one deployment per worker node).
- update Deployment on yanet crd changes.
- delete Deployment when yanet crd removed.
Description
Yanet Operator
Getting Started
You’ll need a Kubernetes cluster to run against. You can use KIND to get a local cluster for testing, or run against a remote cluster.
Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info
shows).
Running on the cluster
- Install Instances of Custom Resources:
kubectl apply -f config/samples/
- Build and push your image to the location specified by
IMG
:
make docker-build docker-push IMG=<some-registry>/yanet-operator:tag
- Deploy the controller to the cluster with the image specified by
IMG
:
make deploy IMG=<some-registry>/yanet-operator:tag
Update helm chart
- Build image:
make docker-build
- tag image and push it.
- Update crds(if need):
make manifests; ./bin/kustomize build config/crd > deploy/charts/yanet-operator/crds/yanet.yaml
- Update rbac roles(if need):
make manifests; ./bin/kustomize build config/rbac/ | sed 's/system/{{ .Values.namespace }}/g' > deploy/charts/yanet-operator/templates/rbac.yaml
- Update version in helm chart.
Uninstall CRDs
To delete the CRDs from the cluster:
make uninstall
Undeploy controller
UnDeploy the controller from the cluster:
make undeploy
How it works
This project aims to follow the Kubernetes Operator pattern.
It uses Controllers,
which provide a reconcile function responsible for synchronizing resources until the desired state is reached on the cluster.
Test It Out
- Install the CRDs into the cluster:
make install
- Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):
make run
NOTE: You can also run this in one step by running: make install run
Modifying the API definitions
If you are editing the API definitions, generate the manifests such as CRs or CRDs using:
make manifests
NOTE: Run make --help
for more information on all potential make
targets
