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
复制代码 去 /var/lib/docker/containers/ 目录下
修改对应镜像的配置。
(镜像配置以作为文件夹名)。
hostconfig.json
eg. 将 3306 改为 3307
- "NetworkMode": "default",
- "PortBindings": {
- "3306/tcp": [

- "HostIp": "",
