1.【minio1】

docker-compose.yml

version: '3.7'
services:
  minio1:
    image: harbocto.xxx.com.cn/public/minio:RELEASE.2021-02-01T22-56-52Z
    volumes:
      - ./data1-1:/data1
      - ./data1-2:/data2
    environment:
      MINIO_ROOT_USER: minio
      MINIO_ROOT_PASSWORD: liubei@2021
    network_mode: host
    command: server http://minio{1...3}/data{1...2}
    extra_hosts:
      - "minio1:10.10.239.66"
      - "minio2:10.10.239.68"
      - "minio3:10.10.239.69"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3

说明：

extra_hosts:
定义容器中的hosts，使得上边 command 后边的地址可以被解析，否则你要写成：
command: server  http://10.10.239.66/data1 http://10.10.239.66/data2 http://10.10.239.68/data1  http://10.10.239.68/data2 http://10.10.239.69/data1 http://10.10.239.69/data2
network_mode: host
多机集群必须从host模式启动，否则磁盘会找不到。

2.【minio2】

docker-compose.yml

version: '3.7'
services:
  minio2:
    image: harbocto.xxx.com.cn/public/minio:RELEASE.2021-02-01T22-56-52Z
    volumes:
      - ./data2-1:/data1
      - ./data2-2:/data2
    environment:
      MINIO_ROOT_USER: minio
      MINIO_ROOT_PASSWORD: liubei@2021
    network_mode: host
    command: server http://minio{1...3}/data{1...2}
    extra_hosts:
      - "minio1:10.10.239.66"
      - "minio2:10.10.239.68"
      - "minio3:10.10.239.69"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3

3.【minio3】

docker-compose.yml

version: '3.7'
services:
  minio3:
    image: harbocto.xxx.com.cn/public/minio:RELEASE.2021-02-01T22-56-52Z
    volumes:
      - ./data3-1:/data1
      - ./data3-2:/data2
#    ports:
#      - "8000:9000"
    environment:
      MINIO_ROOT_USER: minio
      MINIO_ROOT_PASSWORD: liubei@2021
    network_mode: host
    command: server http://minio{1...3}/data{1...2}
    extra_hosts:
      - "minio1:10.10.239.66"
      - "minio2:10.10.239.68"
      - "minio3:10.10.239.69"
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3

4.【nginx】

做负载的nginx容器，我只在minio1 上启动了一个
如果要做高可用，可以在每台minio上启动一个nginx，然后用Keepalive+VIP 来完成。

docker-compose.yml

version: '3.7'
services:
  nginx:
    container_name: nginx
    image: harbocto.xxx.com.cn/public/nginx:1.19.2-alpine
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf:ro
    ports:
      - "80:9000"
    extra_hosts:
      - "minio1:10.10.239.66"
      - "minio2:10.10.239.68"
      - "minio3:10.10.239.69"

nginx.conf

                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;
