shell脚本实现docker运行镜像挂载

news 2025/5/13 6:56:11

根据本文脚本展示内容可以实现多种容器挂载

演示nginx挂载

创建挂载目录
mkdir -p /data/nginx/{conf,html,logs}

参数含义：

docker run -d --name 给运行的镜像取名 -v /宿主机/目录:/容器内/目录镜像名

示例：

docker启动nginx（当前使用docker默认网络）

    docker run -d --name nginx \
        -p 80:80 \
        -v /data/nginx/conf:/etc/nginx/conf.d \
        -v /data/nginx/html:/usr/share/nginx/html \
        -v /data/nginx/logs:/var/log/nginx \
        --restart unless-stopped \
        nginx:latest

完整shell脚本（包含Redis，MySQL，es，nginx）

若有需要，可自行扩展
