Docker 部署 Graylog + Opensearch + MongoDB docker-compose.yml 配置文件

首先拉取官方镜像，然后查看确认镜像是否下载完成

[root@localhost graylog]# docker images
REPOSITORY                     TAG       IMAGE ID       CREATED         SIZE
graylog/graylog                5.2       7f62f560e26c   4 days ago      538MB
mongo                          latest    2e123a0ccb4b   2 weeks ago     757MB
opensearchproject/opensearch   latest    c88bc2cd4d18   5 weeks ago     1.22GB

创建 docker-compose.yml 文件，以便一步简单启动，内容如下：

version: '3'
services:
mongodb:
    image: mongo:latest
    container_name: mongodb
    ports:
      - "27017:27017"
    volumes:
      # 在主机创建目录，以便永久保存数据。
      - /home/project/mongo/data:/data/db
    networks:
      - graylog-net

opensearch:
    image: opensearchproject/opensearch:latest
    container_name: opensearch
    ports:
      - "9200:9200"
    volumes:
      # 设置存储目录，以便永久存储日志
      - /home/project/opensearch/data:/usr/share/opensearch/data
    environment:
      - discovery.type=single-node
    # `Xms` specifies the initial memory allocation pool. `Xmx` specifies the maximum allocation pool for the Java Virtual Machine (JVM). "m" and "g" obviously stand for MB and GB.
    - ES_JAVA_OPTS=-Xms512m -Xmx1g
    # 需要关闭以下安全选项，否则无法连接
    - plugins.security.ssl.http.enabled=false
    - plugins.security.disabled=true
    networks:
    - graylog-net

graylog:
    image: graylog/graylog:5.2
    container_name: graylog
    environment:
    # 配置项需以GRAYLOG_开头，并且是全大写的
    # 密码加密值，不能小于16个字符
    # 运行以下命令获取：< /dev/urandom tr -dc A-Z-a-z-0-9 | head -c${1:-96};echo;
    - GRAYLOG_PASSWORD_SECRET=输入你的
    - GRAYLOG_HTTP_EXTERNAL_URI=http://0.0.0.0:9000/
    - GRAYLOG_WEB_ENDPOINT_URI=http://0.0.0.0:9000/api
    # 运行以下命令获取：echo -n "Enter Password: " && head -1 </dev/stdin | tr -d '\n' | sha256sum | cut -d" " -f1
    - GRAYLOG_ROOT_PASSWORD_SHA2=输入你的
    #- GRAYLOG_REST_LISTEN_URI=http://0.0.0.0:12900/
    - GRAYLOG_MONGODB_URI=mongodb://mongodb:27017/graylog
    # 虽然使用 opensearch，但设置项名称还是 elasticsearch 的
    - GRAYLOG_ELASTICSEARCH_HOSTS=http://opensearch:9200
    #- GRAYLOG_ELASTICSEARCH_USERNAME=admin
    #- GRAYLOG_ELASTICSEARCH_PASSWORD=admin
    # 配置时区
    - GRAYLOG_ROOT_TIMEZONE=Asia/Shanghai
    ports:
    - "9000:9000"
    - "12201:12201/udp"
    networks:
    - graylog-net
    depends_on:
    - mongodb
    - opensearch

networks:
graylog-net:
    driver: bridge

Graylog 启动：转到保存 docker-compose.yml 文件的目录内，运行 docker-compose up -d，就可以正常启动，然后登录 web 页面进行设置操作；

如果操作没问题应该不会出现下面的问题

第一次启动后，浏览器输入 http://graylog主机:9000，登录页面提示你输入用户名和密码。如果输入用户名：admin，密码：你自己设置的，无法登录的话，请输入以下命令 docker log graylog 查看 graylog 的 log，以便查找初始设置密码，一般如下提示;

It seems you are starting Graylog for the first time. To set up a fresh install, a setup interface has
been started. You must log in to it to perform the initial configuration and continue.

Initial configuration is accessible at 0.0.0.0:9000, with username 'admin' and password 'xdxFeehggd'.
