创建支持ssh服务的镜像

解决了，用命令docker run -it -p 80:80 --net="bridge" 来映射端口就行 原来之前映射端口都失败了，需要指定--net 收起

curl 宿主机ip:映射容器80端口，看看报什么错误 收起

回复 3# cherry4477


    尝试更换DNS地址 收起

Apache在容器中curl 127.0.0.1:80  显示index.html内容如下：

hello,docker!

这样我认为Apache服务就是起来了啊，可是问题是：
映射端口打开容器后，却提示域名无法解析是怎么回事啊？请教高手啊 收起

给你贴个SSH的Dockerfile 你参考下
