MinIO 是一个基于 Apache License v2.0 开源协议的对象存储服务。它兼容亚马逊 S3 云存储服务接口,非常适合于存储大容量非结构化的数据,例如图片、视频、日志文件、备份数据和容器/虚拟机镜像等,而一个对象文件可以是任意大小,从几 kb 到最大 5T 不等。
这里采用docker-compose搭建
# 可参考 https://docs.min.io/docs/minio-docker-quickstart-guide.html
version: '3'
services:
minio:
image: minio/minio:latest # 原镜像`minio/minio:latest`
container_name: minio # 容器名为'minio'
restart: unless-stopped # 指定容器退出后的重启策略为始终重启,但是不考虑在Docker守护进程启动时就已经停止了的容器
volumes: # 数据卷挂载路径设置,将本机目录映射到容器目录
- "./minio/data:/data"
- "./minio/minio:/minio"
- "./minio/config:/root/.minio"
environment: # 设置环境变量,相当于docker run命令中的-e
TZ: Asia/Shanghai
LANG: en_US.UTF-8
MINIO_PROMETHEUS_AUTH_TYPE: "public"
MINIO_ACCESS_KEY: "root" # 登录账号
MINIO_SECRET_KEY: "password" # 登录密码
command: server /data --console-address ":9001"
logging:
driver: "json-file"
options:
max-size: "100m"
ports: # 映射端口
- "9000:9000" # 文件上传&预览端口
- "9001:9001" # 控制台访问端口
启动服务
docker-compose -f docker-compose-minio.yml -p minio up -d
