不能使用SSH连接到docker容器 [英] Not able to connect to docker containers using SSH

问题描述

我是Docker的新手，我从Dockerfile构建了容器，我可以看到容器的创建和运行，但是我无法使用ssh连接到该容器。

这是我的Docker文件：

  FROM ubuntu：12.04 
 
 RUN apt-get更新
运行apt-get install -y apache2& openssh-server 
 
 ENV APACHE_RUN_USER www-data 
 ENV APACHE_RUN_GROUP www-data 
 ENV APACHE_LOG_DIR / var / log / apache2 
 
 EXPOSE 80 
 EXPOSE 22 
 
 ENTRYPOINT [/ usr / sbin / apache2] 
 CMD [-D，FOREGROUND] 
  pre> 
 
 
然后我运行这个cmd：
  docker build -t =apache2。 
 $ docker run -d apache2 
  
当我做 docker ps ，我可以看到端口被分配，但是我无法使用ssh连接到该容器。
 
 
 
 $ docker ps 
  ID IMAGE COMMAND CREATED STATUS PORTS 
 5765535796f8 apache2：最新/ usr / sbin / apache2 -D大约一分钟前关于a分49154-> 80,49155-> 22 
  
 
 
解决方案
  
 
 
 运行apt-get install -y apache2& openssh-server  
 
 
 
应该是
 
 
 
  -get install -y apache2 openssh-server  
 
 
 
如果您更改此选项，以及添加步骤设置root密码，如运行ssh服务指南是否可以将ssh插入运行容器？

I am new to Docker, I built the container from a Dockerfile, and I can see the container creating and running, but I am not able to connect to that container using ssh.

Here is my Dockerfile:
FROM ubuntu:12.04

RUN apt-get update
RUN apt-get install -y apache2 & openssh-server

ENV APACHE_RUN_USER www-data
ENV APACHE_RUN_GROUP www-data
ENV APACHE_LOG_DIR /var/log/apache2

EXPOSE 80
EXPOSE 22

ENTRYPOINT ["/usr/sbin/apache2"]
CMD ["-D", "FOREGROUND"]
Then I ran this cmd:
docker build -t="apache2" .
$ docker run -d apache2
When I do docker ps, I can see the port is assigned, but I am not able to connect to that container using ssh.

$ docker ps
ID                  IMAGE               COMMAND                CREATED              STATUS              PORTS
5765535796f8        apache2:latest      /usr/sbin/apache2 -D   About a minute ago   Up About a minute   49154->80,49155->22

解决方案
It looks like there's a typo in your docker file.  Line:

RUN apt-get install -y apache2 & openssh-server

should be

RUN apt-get install -y apache2 openssh-server

If you change this as well as add the steps to setting the root password as shown in the "running an ssh service guide" are you able to ssh into your running container?
