如何修改Docker镜像的映射端口号

目录

点窜Docker镜像的映照端口号

先检察已存在的镜像的CONTAINER ID去 /var/lib/docker/containers/ 目录下eg. 将 3306 改成 3307重启 Docker

点窜Docker镜像的映照端口号


先检察已存在的镜像的CONTAINER ID

1. [root@192 mysql_geek]# docker ps
2. CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
3. 841d16cc9175        mysql:5.7.29        "docker-entrypoint.s…"   23 hours ago        Up 23 hours         0.0.0.0:3306->3306/tcp, 33060/tcp   mysql_geek

复制代码

去 /var/lib/docker/containers/ 目录下

点窜对应镜像的设置。
（镜像设置以 CONTAINER ID 作为文件夹名）。
