前提
- 需要一個(gè) kubernetes 集群
- 需要提供 csi（數(shù)據(jù)持久化）
部署步驟
- 部署 crd
kubectl create -f https://download.elastic.co/downloads/eck/2.12.1/crds.yaml
- 部署
elastic-operator
# 默認(rèn)在 elastic-system命名空間下
kubectl apply -f https://download.elastic.co/downloads/eck/2.12.1/operator.yaml
- 查看部署日志
kubectl -n elastic-system logs -f statefulset.apps/elastic-operator
- 部署一個(gè) elasticsearch 集群實(shí)例
