如何修改Docker镜像的映射端口号_云虚拟主机

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

"portbindings": {
"3306/tcp": [
{
"hostip": "",
"hostport": "3307"
