這篇文章主要介紹了如何修改Docker鏡像的映射端口號(hào)問(wèn)題,具有很好的參考價(jià)值,希望對(duì)大家有所幫助,如有錯(cuò)誤或未考慮完全的地方,望不吝賜教

修改Docker鏡像的映射端口號(hào)

先查看已存在的鏡像的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/ 目錄下

修改對(duì)應(yīng)鏡像的配置。

（鏡像配置以 CONTAINER ID 作為文件夾名）。

hostconfig.json

eg. 將 3306 改為 3307

"3306/tcp": [
