如何使用vnc在Ubuntu中运行docker image？ [英] How to run docker image in ubuntu with vnc?

问题描述

为了检查在docker映像中运行的硒测试，我试图设置一个VNC来验证测试过程中发生的事情。

In order to examine selenium tests running inside a docker image I am trying to set up a VNC to verify what is going on during the tests.

我正在遵循提出的建议此处，并在 Dockerfile 中用以下附加行创建了新的Docker映像：

I am following the suggestions made here and created a new docker image with the following additional lines in Dockerfile:

RUN     apt-get install -y x11vnc 
RUN     mkdir ~/.vnc
RUN     x11vnc -storepasswd 1234 ~/.vnc/passwd

然后我使用以下命令启动docker映像：

Then I started the docker image with the following command:

docker run -p 5900 --rm -it --entrypoint /bin/bash selenium-tests

并开始 krdc 作为我的VNC查看器。那么现在怎么办？

and started krdc as my VNC viewer. So now what?

我在 krdc 中看不到我的docker映像。也许我缺少什么？我是否必须在docker内部显式启动vnc代码？我是否需要将其他参数传递给 docker 命令？

I do not see my docker image in krdc. Maybe I am missing something? Do I have to start the vnc code inside docker explicitly? Do I need to pass additional arguments to the docker command?

• docker：1.13 .1


• ubuntu：16.4.03


• krdc：4.14.16

推荐答案

问题中有两个问题使您无法实现想要达到的目标：

There are two issues in the question that prevent you from the goal you want to achieve:

1。图像中缺少X服务器。

1. X server is missed in the image.

2。 VNC服务器应在容器中启动。

2. VNC server should be started in a container.

Dockerfile 的其他部分是：

RUN apt-get install -y x11vnc xvfb 
RUN mkdir ~/.vnc
RUN x11vnc -storepasswd 1234 ~/.vnc/passwd
COPY entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]

其中 entrypoint.sh 是：

#!/bin/bash
x11vnc -forever -usepw -create &
/bin/bash

现在我们可以使用以下命令启动容器：

Now we can start a container using the following command:

docker run --rm -ti -p 5900:5900 <image_name_or_id>

并通过 vncviewer 进行访问启动容器的主机：

and access it via vncviewer from the same host where container is started:

vncviewer localhost:5900
