安装 ECK-Operator

kubectl create -f https://download.elastic.co/downloads/eck/1.9.1/crds.yaml

kubectl apply -f https://download.elastic.co/downloads/eck/1.9.1/operator.yaml

创建完成结果

kubectl -n elastic-system get all

部署主从集群架构(在这之前需要先创建 storage class)

ok,安装完成

访问 kibana

https://192.168.100.132:31665/login?next=%2F

#账户名称:elastic
获取密码
#密码
PASSWORD=$(kubectl -n eck get secret elastic-es-elastic-user -o=jsonpath=‘{.data.elastic}’ | base64 --decode)
echo $PASSWORD

输入控制台打印的密码

OK,没什么问题

删除卸载

kubectl -n eck delete kibana kibana

kubectl -n eck delete elasticsearch elastic

镜像无法下载问题解决:

docker pull elastic/elasticsearch:7.6.2

docker pull elastic/kibana:7.6.2

docker tag elastic/elasticsearch:7.6.2 docker.elastic.co/elasticsearch/elasticsearch:7.6.2

docker tag elastic/kibana:7.6.2 docker.elastic.co/kibana/kibana:7.6.2
