简书链接:docker修改现有镜像增加端口，增加调整卷映射
文章字数：879,阅读全文大约需要3分钟
简书出现了致命问题，我2台电脑都无法上传图片，所以。。

查看容器信息：
（在openwrt中无需操作，直接点开容器就能看到id）
docker ps -a
查看容器的端口映射情况
docker port 容器ID或者容器名称
docker inspect 容器Id | grep Id
cd /etc/docker/containers
就可以看到一系列以文件id命名的文件夹

打开文件夹

-rw-r--r--    1 root     root            71 Sep  5 10:32 resolv.conf.hash

需要修改的是config.v2.json和hostconfig.json
为了方便操作，使用MobaXterm连接终端，然后打开文件打开用vscode进行格式化json
【保存后自动上传】
config.v2.json
这里的Ports可能不需要改，似乎运行后自动会出现
