在Docker容器中安装ssh [英] installing ssh in the docker containers
问题描述
我有一个托管docker容器的ubuntu机器。
，并且在docker容器中，我正在运行一个Web服务，该服务必须使用docker主机的/ etc / password验证
的用户密码。
i have a ubuntu machine that hosts a docker container. and in the docker container i am running a web service which must validate the user's password with the docker host's /etc/password.
my视图是从docker容器SSH到docker主机。
，所以当我在Docker容器中运行命令ssh时，找不到ssh。
因此，基本上ssh尚未安装在容器中。
我如何在容器中安装ssh。
有什么方法可以完成这种情况吗？。
my view is to ssh into docker host from the docker container. so when i run command ssh in the docker container its saying ssh not found. so,basically ssh is not installed in the container. how can i install ssh in the container. is there any way to accomplish this scenario?.
推荐答案
作为图像文件的一部分，您将只需安装openssh服务器：
Well, as part of the image file you'll simply have to install openssh-server:
sudo apt-get install openssh-server
然后的问题是，传统上，正在运行的docker容器将仅运行单个命令。您可以通过使用supervisor之类的方法来解决此问题。码头工人文档中有一个示例： https://docs.docker.com/engine/admin/ using_supervisord /
The problem then is that traditionally, a running docker container will only run a single command. You can get around this problem by using something like supervisord. There's an example in the docker docs: https://docs.docker.com/engine/admin/using_supervisord/
您的dockerfile可能看起来像这样：
Your dockerfile might look like this:
FROM ubuntu:16.04
MAINTAINER examples@docker.com
RUN apt-get update && apt-get install -y openssh-server apache2 supervisor
RUN mkdir -p /var/lock/apache2 /var/run/apache2 /var/run/sshd /var/log/supervisor
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
EXPOSE 22 80
CMD ["/usr/bin/supervisord"]
您的supervisord.conf可能看起来像这样：
Your supervisord.conf might look something like this:
[supervisord]
nodaemon=true
[program:sshd]
command=/usr/sbin/sshd -D
[program:apache2]
command=/bin/bash -c "source /etc/apache2/envvars && exec /usr/sbin/apache2 -DFOREGROUND"
