docker compose部署minio报错

背景

部分服务使用docker-compose单节点编排，其中对象存储服务使用minio，在minio中配置了aksk后报错
Error: IAM sub-system is partially initialized, unable to write the IAM forma

解决

minio如果配置了aksk等iam类的配置则需要持久化存储到etcd

在minio的部署文件中新增etcd配置。

  etcd:
    image: bitnami/etcd:3.5.18
    container_name: etcd
    environment:
      ALLOW_NONE_AUTHENTICATION: yes
      ETCD_ADVERTISE_CLIENT_URLS: http://etcd:2379
      ETCD_LISTEN_CLIENT_URLS: http://0.0.0.0:2379
    ports:
      - "2379:2379"
    networks:
      - net1
    volumes:
      - /data/etcd:/bitnami/etcd

  minio:
    image: minio/minio
    container_name: minio
    command: server /data --console-address :9001
    hostname: minio
    restart: always
    environment:
      MINIO_ROOT_USER: admin
      MINIO_ROOT_PASSWORD: admin123
      MINIO_IAM_STORAGE_BACKEND: etcd
      MINIO_ETCD_ENDPOINTS: http://etcd:2379
    volumes:
      - /data/minio:/data
    ports:
      - "9000:9000"
      - "9001:9001"
    networks:
      - net1
