文章目录

1. 部署

按照官网流程进行部署

使用 Docker 安装 Elasticsearch |Elasticsearch 指南 [8.14] |弹性的

需要提前准备好 elasticsearch:8.14.3 镜像

1.1 单节点

  1. docker-compose.yml

    # es
docker run --name es01 --net elastic -p 9200:9200 -it -m 1GB docker.elastic.co/elasticsearch/elasticsearch:8.14.3
# kibana
docker run --name kibana --net elastic -p 5601:5601 docker.elastic.co/kibana/kibana:8.14.3

    官网是docker run命令，我们直接改成docker-compose格式进行部署：

    version: "3.8"
services:
  es01:
    image: elasticsearch:8.14.3
    container_name: es01
    networks:
    - elastic
    ports:
    - "9200:9200"
    mem_limit: 1g

  kibana:
    image: kibana:8.14.3
    container_name: kibana
    networks:
    - elastic
    ports:
    - "5601:5601"

networks:
  elastic:
    driver: bridge

  2. Cosign 验证

    Cosign 是一个用于签名和验证容器镜像的工具，它允许用户对镜像进行数字签名，并验证签名以确保镜像的完整性和来源。通过使用 Cosign，你可以创建和管理镜像的签名，并在部署时验证这些签名，以确保镜像的安全性。

    总结起来就是对镜像的上传和下载做签名验证，本文不做验证

  3. 启动查看

    docker ps

    在这里插入图片描述

    容器启动正常

    查看kibana登录地址docker logs kibana

    在这里插入图片描述

    尽管我们已经配置了kibana的端口映射，但是由于我们目前没有任何kibana相关配置，所以启动需要用kibana生成出来的地址，不然还得找，就像下面这样

    在这里插入图片描述

    从生成的地址登录到kibana

    在这里插入图片描述

    生成令牌，贴到框中

    # 生成令牌命令
docker exec -it es01 /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana

# 输出如下，一个base64编码的字符串
eyJ2ZXIiOiI4LjE0LjAiLCJhZHIiOlsiMTcyLjE4LjAuMzo5MjAwIl0sImZnciI6IjM4YjQxZTVmYjI1ODFiZjg0OGVjMTZkMDA1ZGRlNDliODlhZWI2OGQyYWU5NjEwOWNhNTJlNDRkM2VkYTYzNTkiLCJrZXkiOiJpYmdzdnBNQmhFZWlxSUlWZ21qUzpTUFFINFVqU1NsLWpGN0tWTVRTTk1RIn0=

    在这里插入图片描述

    configure Elastic

    在这里插入图片描述

    跑完后会进入到登录页面：

    在这里插入图片描述

    Username默认是 elastic

    密码我们不知道，直接生成一个新的

    docker exec -it es01 bin/elasticsearch-reset-password -u elastic

    在这里插入图片描述

    用新密码登录，登录成功

  4. 查看es节点状态

    GET /_cat/health?v&format=json

    green就是健康

    在这里插入图片描述

1.2 新节点加入集群

  1. 使用现有节点生成令牌

    令牌注册时间为30分钟

    docker exec -it es01 /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node

    在这里插入图片描述

  2. 启动新的 Elasticsearch 容器。将注册令牌作为环境变量包含在内

    docker run -d -e ENROLLMENT_TOKEN="eyJ2ZXIiOiI4LjE0LjAiLCJhZHIiOlsiMTcyLjE4LjAuMzo5MjAwIl0sImZnciI6IjM4YjQxZTVmYjI1ODFiZjg0OGVjMTZkMDA1ZGRlNDliODlhZWI2OGQyYWU5NjEwOWNhNTJlNDRkM2VkYTYzNTkiLCJrZXkiOiJ0TGpVdnBNQmhFZWlxSUlWZ0doWDp1Nk1MOWV3dlNBT09XX2hSX090b0ZRIn0=" --name es02 --net bigdata_elastic -it -m 1GB elasticsearch:8.14.3

  4. 查看节点是否加入集群

    GET /_cat/nodes?v&format=json

    在这里插入图片描述

    GET /_cat/health?v&format=json

    在这里插入图片描述

  5. 加入成功

1.3 docker-compose部署集群

  1. 创建.env

    # Password for the 'elastic' user (at least 6 characters)
ELASTIC_PASSWORD=Qianyue@2024

# Password for the 'kibana_system' user (at least 6 characters)
KIBANA_PASSWORD=Qianyue@2024

# Version of Elastic products
STACK_VERSION=8.14.3

# Set the cluster name
CLUSTER_NAME=elastic-cluster

# Set to 'basic' or 'trial' to automatically start the 30-day trial

#LICENSE=trial

# Port to expose Elasticsearch HTTP API to the host
ES_PORT=9200
#ES_PORT=127.0.0.1:9200

# Port to expose Kibana to the host

#KIBANA_PORT=80

# Increase or decrease based on the available host memory (in bytes)
MEM_LIMIT=1073741824

# Project namespace (defaults to the current folder name if not set)
#COMPOSE_PROJECT_NAME=myproject
