openGemini-operator

Description

Cloud Native Installation and Deployment of opengemini database using K8S.

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

1. Install helm:

curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

2. Add chart repo:

helm repo add opengemini https://opengemini.github.io/openGemini-operator

3. Install chart(both CRDs and operator) in specified namespace:

kubectl create ns opengemini-system
helm install opengemini-operator opengemini/operator -n opengemini-system

4. Deploy cluster in specified namespace, you can copy example configuration file to local path and modify it:

kubectl create ns opengemini
kubectl -n opengemini create -f config/samples/_v1_opengeminicluster.yaml

5. Uninstall chart:

helm uninstall opengemini-operator -n opengemini-system

Contributing

Please read the Contribution guide of opengemini repo first.

How it works

This project aims to follow the Kubernetes Operator pattern.

It uses Controllers which provides a reconcile function responsible for synchronizing resources until the desired state is reached on the cluster.

Test It Out

1. Install the CRDs into the cluster:

make install

2. 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

Uninstall CRDs

To delete the CRDs from the cluster:

make uninstall

Undeploy controller

UnDeploy the controller to the cluster:

make undeploy

NOTE: Run make --help for more information on all potential make targets
