ElasticSearch 使用 Skaffold 的 Kube.netes 安装

Question

我喜欢弹性搜索，所以在我的新项目中，我一直在努力让它在 Kube.netes 和 skaffold 上运行

这是我写的 yaml 文件：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: eks-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: eks
  template:
    metadata:
      labels:
        app: eks
    spec:
      containers:
        - name: eks
          image: elasticsearch:7.17.0
---
apiVersion: v1
kind: Service
metadata:
  name: eks-srv
spec:
  selector:
    app: eks
  ports:
    - name: db
      protocol: TCP
      port: 9200
      targetPort: 9200
    - name: monitoring
      protocol: TCP
      port: 9300
      targetPort: 9300

在我运行 skaffold dev 之后，它显示正在通过 Kube.netes 工作，但几秒钟后它崩溃并关闭。

我不明白我做错了什么。

在我以 Harsh Manvar 先生的身份更新我的配置文件后，它就像一个魅力，但目前我面临另一个问题。 客户端说以下......

顺便说一句，我正在使用 ElasticSearch 版本 7.11.1 和客户端模块“@elastic/elasticsearch^7.11.1”

如果您计划在 Kube.netes 上运行单个节点 elasticsearch 集群，则应考虑运行示例 YAML 文件

apiVersion: apps/v1
kind: StatefulSet
metadata:
  labels:
    app: elasticsearch
    component: elasticsearch
    release: elasticsearch
  name: elasticsearch
  namespace: default
spec:
  podManagementPolicy: OrderedReady
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      app: elasticsearch
      component: elasticsearch
      release: elasticsearch
  serviceName: elasticsearch
  template:
    metadata:
      labels:
        app: elasticsearch
        component: elasticsearch
        release: elasticsearch
    spec:
      containers:
      - env:
        - name: cluster.name
          value: es_cluster
        - name: ELASTIC_PASSWORD
          value: xyz-xyz
        - name: discovery.type
          value: single-node
        - name: path.repo
          value: backup/es-backup
        - name: ES_JAVA_OPTS
          value: -Xms512m -Xmx512m
        - name: bootstrap.memory_lock
          value: "false"
        - name: xpack.security.enabled

          requests:

        securityContext:

          runAsUser: 1000
        terminationMessagePath: /dev/termination-log
        terminationMessagePolicy: File
        volumeMounts:
        - mountPath: /usr/share/elasticsearch/data
          name: elasticsearch-data
      dnsPolicy: ClusterFirst
      initContainers:
      - command:
        - sh
        - -c
        - chown -R 1000:1000 /usr/share/elasticsearch/data
        - sysctl -w vm.max_map_count=262144
        - chmod 777 /usr/share/elasticsearch/data
        - chomod 777 /usr/share/elasticsearch/data/node
        - chmod g+rwx /usr/share/elasticsearch/data

        resources: {}
        securityContext:
          privileged: true
        terminationMessagePath: /dev/termination-log
        terminationMessagePolicy: File
        volumeMounts:
        - mountPath: /usr/share/elasticsearch/data
          name: elasticsearch-data
      restartPolicy: Always
      schedulerName: default-scheduler
      securityContext: {}
      terminationGracePeriodSeconds: 10
  updateStrategy:
    type: OnDelete
  volumeClaimTemplates:
  - metadata:
      creationTimestamp: null
      name: elasticsearch-data
    spec:
      accessModes:
      - ReadWriteOnce
      resources:
        requests:
          storage: 10Gi
      volumeMode: Filesystem

我还建议查看 elasticsearch 的舵图：

1 . https://github.com/elastic/helm-charts/tree/master/elasticsearch

2. https://github.com/helm/charts/tree/master/stable/elasticsearch

您可以使用该服务公开上述有状态集，并在应用程序中进一步使用。
