Docker下MinIO的使用

Docker下MinIO的使用

1. 镜像

我们可以去 Docker Hub (opens new window) 查询版本号，官网: https://docs.min.io/cn/minio-quickstart-guide.html (opens new window)，文档也很全，可以看到 Docker 的命令，这里我们下稳定版

然后直接启动 Docker，执行命令 docker pull minio/minio 下载稳定版本镜像，使用命令 docker images 查看下载的镜像

2. 启动

查看官网: https://docs.min.io/cn/minio-docker-quickstart-guide.html (opens new window)，直接有启动的命令

执行命令启动单点模式

docker run -p 9000:9000 --name minio minio/minio server /data

启动成功，可以访问后台界面: http://127.0.0.1:9000 (opens new window)，Access Key 和 Secret Key 在命令行那有显示，都是 minioadmin

单点模式的话所有的数据都会在容器退出时丢失，所以可以指定磁盘对应起来，注意文件夹需要自行提前建立好

docker run -p 9000:9000 --name minio1 -v D:\Tools\docker\minio:/data minio/minio server /data

还可以指定 Access Key 和 Secret Key

docker run -p 9000:9000 --name minio2 -e "MINIO_ACCESS_KEY=AKIAIOSFODNN7EXAMPLE" -e "MINIO_SECRET_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" -v D:\Tools\docker\minio:/data minio/minio server /data

只是启动容器命令不一样而且，启动后都是一样的，这里就不示例了

3. 集群

直接看官网: 在Docker Compose上运行分布式MinIO (opens new window)，贴下 docker-compose.yml (opens new window)

version: '3.7'

# starts 4 docker containers running minio server instances. Each
# minio server's web interface will be accessible on the host at port
# 9001 through 9004.

      - data3-2:/data2
    ports:
      - "9003:9000"
    environment:
      MINIO_ACCESS_KEY: minio
      MINIO_SECRET_KEY: minio123
    command: server http://minio{1...4}/data{1...2}
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3

  minio4:
    image: minio/minio:RELEASE.2020-01-16T22-40-29Z
    container_name: minio4
    volumes:
      - data4-1:/data1
      - data4-2:/data2
    ports:
      - "9004:9000"
    environment:
      MINIO_ACCESS_KEY: minio
      MINIO_SECRET_KEY: minio123
    command: server http://minio{1...4}/data{1...2}
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3

## By default this config uses default local driver,
## For custom volumes replace with volume driver configuration.
volumes:
  data1-1:
  data1-2:
  data2-1:
  data2-2:
  data3-1:
  data3-2:
  data4-1:
  data4-2:

执行

// 下载镜像
docker-compose pull
// 启动
docker-compose up

现在每个实例都可以访问，端口从9001到9004，请在浏览器中访问，而且4个端口的服务文件都是共享的，就不贴图了
