Elasticsearch 使用随记

部署 ECK Operator：

kubectl create -f https://download.elastic.co/downloads/eck/2.16.1/crds.yaml
kubectl apply -f https://download.elastic.co/downloads/eck/2.16.1/operator.yaml

部署单点 ES 集群：

cat <<EOF | kubectl apply -f -
apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: quickstart
spec:
  version: 8.17.1
  nodeSets:
  - name: default
    count: 1
    config:
      node.store.allow_mmap: false
EOF

对集群发起请求：

PASSWORD=$(kubectl get secret quickstart-es-elastic-user -o go-template='{{.data.elastic | base64decode}}')
curl -u "elastic:$PASSWORD" -k "https://quickstart-es-http:9200"

部署高可用 ES 集群：

cat <<EOF | kubectl apply -f -
apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: quickstart
spec:
  version: 8.17.1
  nodeSets:
  - name: data-nodes
    count: 3
    config:
      node.store.allow_mmap: false
      index.number_of_replicas: 1
  - name: master-nodes
    count: 3
    config:
      node.master: true
      node.data: false
      node.ingest: false
      heap.size: 2g
EOF
