如何修改Docker镜像的映射端口号

修改Docker镜像的映射端口号


先查看已存在的镜像的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

修改对应镜像的配置。
（镜像配置以

1. CONTAINER ID

复制代码

作为文件夹名）。
hostconfig.json

eg. 将 3306 改为 3307

1.     "NetworkMode": "default",
   
2. "PortBindings": {
   
3. "3306/tcp": [
   
4. {
   
5. "HostIp": "",
   
6. "HostPort": "3307"
   
7. }
   
8. ]
   
9. },
