OCI環境のOKEで構成されたKuberntesコンテナーへYugabyteDBを構築しました。
作業時のメモです。
Docker Desktop上へ、Podクラスタを組んで遊んでいます。
ノードクラスターは未対応です。
helm repo add yugabytedb https://charts.yugabyte.com
helm repo update
kubectl create namespace yugabyte
helm install yugabyte yugabytedb/yugabyte --set resource.master.requests.cpu=0.5,resource.master.requests.memory=0.5Gi,resource.tserver.requests.cpu=0.5,resource.tserver.requests.memory=0.5Gi,replicas.master=3,replicas.tserver=3,Image.tag=2024.2.3.2-b6 --namespace yugabyte
1. Get YugabyteDB Pods by running this command:
kubectl --namespace yugabyte get pods
2. Get list of YugabyteDB services that are running:
kubectl --namespace yugabyte get services
kubectl exec --namespace yugabyte -it yb-tserver-0 -- /home/yugabyte/bin/ysqlsh -h yb-tserver-0.yb-tservers.yugabyte
6. Cleanup YugabyteDB Pods
For helm 2:
helm delete yugabyte --purge
For helm 3:
helm delete yugabyte -n yugabyte
NOTE: You need to manually delete the persistent volume
kubectl delete pvc --namespace yugabyte -l app=yb-master
kubectl delete pvc --namespace yugabyte -l app=yb-tserver
NOTE: The yugabyted UI is now available and is enabled by default. It requires version 2.21.0 or greater.
If you are using a custom image of YugabyteDB that is older than 2.21.0, please disable the UI by setting yugabytedUi.enabled to false.
