修改Docker镜像的映射端口号

先查看已存在的镜像的CONTAINER ID

[root@192 mysql_geek]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
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

去 /var/lib/docker/containers/ 目录下

修改对应镜像的配置。

（镜像配置以 CONTAINER ID 作为文件夹名）。

hostconfig.json

eg. 将 3306 改为 3307

    "NetworkMode": "default",
"PortBindings": {
"3306/tcp": [

"HostIp": "",
"HostPort": "3307"
