假设你已经完成Swarm的初始化,那么接下来开始部署BladeX服务

1.首先要创建一个自定义网络,后续所有的服务都指定使用这个网络

docker network create -d overlay \
  --subnet=10.10.0.0/16 \
  --gateway=10.10.0.254 \
  --attachable=true \
  ${网络名称}

2. 然后是编写服务DockerCompose文件

2.1 先创建Nacos和Sentinel服务,保存名为(文件名可以自定义):swarm-nacos-sentinel.yml

version: "3.4"
   services:
     nacos-server:
       image: nacos/nacos-server:1.0.0
       hostname: nacos-server
       deploy:
         endpoint_mode: vip
         replicas: 1
         restart_policy:
           condition: on-failure
       networks:
         - ${网络名称}
       environment:
         - MODE=standalone
         - SPRING_DATASOURCE_PLATFORM=mysql
         - MYSQL_MASTER_SERVICE_DB_NAME=${主mysql数据库名称}
         - MYSQL_MASTER_SERVICE_HOST=${主mysql连接}
         - MYSQL_MASTER_SERVICE_USER=${主mysql连接用户名}
         - MYSQL_MASTER_SERVICE_PASSWORD=${主mysql连接密码}
         - MYSQL_SLAVE_SERVICE_HOST=${副mysql连接}
         - MYSQL_SLAVE_SERVICE_DB_NAME=${副mysql数据库名称}
         - MYSQL_SLAVE_SERVICE_USER=${副mysql连接用户名}
         - MYSQL_SLAVE_SERVICE_PASSWORD=${副mysql连接用户名}
       volumes:
         - /docker/nacos/standalone-logs/:/home/nacos/logs
         - /docker/nacos/init.d/custom.properties:/home/nacos/init.d/custom.properties
       ports:
         - "8848:8848"
     sentinel:
       image: bladex/sentinel-dashboard:1.6.0
       hostname: sentinel
       networks:
         - ${网络名称}
       deploy:
         endpoint_mode: vip
         replicas: 1
         restart_policy:
           condition: on-failure
       ports:
         - "8858:8858"
   networks:
     ${网络名称}:
       external: true

2.2 发布nacos和sentinel

docker stack deploy -c warm-nacos-sentinel.yml --with-registry-auth ${服务栈名称}

2.3 编写BladeX服务的DockerCompose文件,保存为:swarm-bladex-apps.yml

version: "3.4"
services:
  blade-gateway:
    image: ${镜像地址}
    hostname: blade-gateway
    networks:
      - ${网络名称}
    deploy:
      endpoint_mode: vip
      replicas: 3
      restart_policy:
        condition: on-failure
    command:
      - --spring.profiles.active=test
      - --spring.cloud.nacos.config.server-addr=nacos-server:8848
      - --spring.cloud.nacos.discovery.server-addr=nacos-server:8848
      - --spring.cloud.nacos.config.group=DEAFULT_GROUP
      - --spring.cloud.sentinel.transport.dashboard=sentinel:8858
      - --spring.cloud.inetutils.preferred-networks=10.0.
    ports:
      - "88:88"
    depends_on:
      - nacos-server
      - sentinel
  
  blade-system:
      image: ${镜像地址}
      hostname: blade-system
      networks:
        - ${网络名称}
      deploy:
        endpoint_mode: vip
        replicas: 1
        restart_policy:
          condition: on-failure
      command:
        - --spring.profiles.active=test
        - --spring.cloud.nacos.config.server-addr=nacos-server:8848
        - --spring.cloud.nacos.discovery.server-addr=nacos-server:8848
        - --spring.cloud.nacos.config.group=DEAFULT_GROUP
        - --spring.cloud.sentinel.transport.dashboard=sentinel:8858
        - --spring.cloud.inetutils.preferred-networks=10.0.
      ports:
        - "8102:8102"
      depends_on:
        - nacos-server
        - sentinel
  ......其他服务一样的写法
networks:
  ${网络名称}:
    external: true

这里要注意的一个地方是服务启动参数里的

--spring.cloud.inetutils.preferred-networks=10.0.

这里指定服务已我们前面创建的那个网络的ip前缀的网卡向nacos注册,如果不加这个参数默认是使用的是Docker自建的网卡,这样的话服务还是访问不了

2.4 发布BladeX服务

docker stack deploy -c warm-bladex-apps.yml --with-registry-auth ${服务栈名称}

这里的服务栈名称和nacos的保持一致,不一样的话行不行我也没试过

2.5 编写Nginx服务的DockerCompose文件,保存为 swarm-nginx.yml

version: "3.4"
services:
  saber-nginx:
    image: nginx:stable-alpine-perl
    hostname: saber-nginx
    ports:
      - 80:80
      - 443:443
    networks:
      - ${网络名称}
    deploy:
      endpoint_mode: vip
      replicas: 1
      restart_policy:
        condition: on-failure
    volumes:
      - /docker/nginx/dist:/usr/share/nginx/html
      - /docker/nginx/nginx.conf:/etc/nginx/nginx.conf
      - /docker/nginx/conf.d:/etc/nginx/conf.d/
    depends_on:
      - blade-gateway

networks:
  ${网络名称}:
    external: true

发布服务前需要把saber编译好的文件放到上边volumes中的位置

/docker/nginx/dist

然后调好nginx的反代设置

replicas: 1  这个参数是节点数量

2.6 发布nginx服务

docker stack deploy -c swarm-nginx.yml --with-registry-auth ${服务栈名称}

3. 分享下我的Nginx配置

nginx.conf:


#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }
    include /etc/nginx/conf.d/*.conf;
}


saber站点配置

补上部署后的图片:

说明一下,我这边改了服务名......按自己的来就好
