MinIO存储在docker安装及使用

MinIO

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。

MinIO是一个非常轻量的服务,可以很简单的和其他应用的结合，类似 NodeJS, Redis 或者 MySQL

docker 安装Minio

安装docker镜像

# docker安装镜像
docker pull minio/minio

容器运行方式① 和容器运行方式② 选择一种就好。

运行容器方式①

# 后台运行容器
docker run -p 9000:9000 --name storage -di -v /storage/data:/data -v /storage/config:/root/.minio --restart=always minio/minio server /data

1，进入容器
docker exec -it storage sh

2，查看配置文件中的key值
cat /data/.minio.sys/config/config.json |grep Key
“accessKey”: “507LX5P57F99DNEVF1GH”,
“secretKey”: “Kc2tllnd9FQrgTzu0RSohir4B4svh2cLiueGZR5x”,
“routingKey”: “”,

运行容器方式②

# 后台运行容器方式
docker run -p 9000:9000 --name storage -di --restart=always \
  -e "MINIO_ACCESS_KEY=superzheng" \
  -e "MINIO_SECRET_KEY=storage/File" \
  -v /storage/data:/data \
  -v /storage/config:/root/.minio \
  minio/minio server /data
  
# -p 端口映射  将外部端口 映射到 容器内部端口  
# --name 自定义容器名称
# -di 后台运行的方式运行
# --restart=always  一旦docker重启或者开启时，也自动启动镜像
# -e 设置系统变量  在这里是设置Minio的ACCESS_KEY和SECRET_KEY
# -v 挂载文件  将系统文件  映射到  容器内部对应的文件夹

这是安装成功的日志：

Docker-compose安装部署MinIO存储服务

环境准备

拉取minio的docker镜像：docker pull minio/minio

创建挂载目录：

[root@test data]# mkdir /mnt/data
[root@test data]# pwd
/mnt/data
[root@test data]# cd /home/app/minio/
[root@test minio]# ls
docker-compose.yaml  minio.tar.gz

编写docker-compose.yaml文件：

[root@test minio]# cat docker-compose.yaml
version: '3'
services:
  miniocheck:
    image: minio/minio:amd64
    command: server /data --console-address ":9001"
    volumes:
      - /mnt/data:/data # 持久化地址
    ports:
      - "9000:9000" # 绑定端口
      - "9001:9001"
    container_name: minio
    restart: always
    environment:
      MINIO_ROOT_USER: admin # 账号
      MINIO_ROOT_PASSWORD: gbase;123 #密码

command指令中添加--console-address参数，否则浏览器访问控制台自动跳转端口导致无法访问，查看日志可看到如下信息：

[root@test minio]# docker-compose logs -f

启动容器并访问

启动容器，查看容器状态：

[root@test minio]# docker-compose up -d
