如何在 docker 上运行电子应用程序

2022-01-10 00:00:00 docker node.js dockerfile electron javascript

我创建了一个托管电子应用程序的存储库的分支，该应用程序是一个聊天客户端:https://github.com/Serkan-devel/BetterDiscordApp-docker.

I've created a fork of a repository hosting an electron app which is a chat client: https://github.com/Serkan-devel/BetterDiscordApp-docker.

我要做的是创建一个 docker 容器，其 GUI 连接到自己的屏幕，例如 https://blog.jessfraz.com/post/docker-containers-on-the-desktop/ .

What I'm trying to do is to create a docker container with a GUI hooked to the own screen like at https://blog.jessfraz.com/post/docker-containers-on-the-desktop/ .

我创建的 dockerfile 如下:

The dockerfile I've created goes like:

FROM node:slim

COPY . /usr/scr/app

#RUN rm bdstart.sh

RUN npm install --save-dev electron

RUN npm install

#ENV FRESHINSTALL=true

CMD ["/usr/scr/app/start.sh"]

start.sh 文件如下:

The start.sh file goes like:

./node_modules/.bin/electron ./src

构建 docker 镜像并使用它执行后

After building the docker image and execute it with

docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=unix$DISPLAY --device /dev/snd dixord

我得到错误代码:

standard_init_linux.go:175: exec user process caused "exec format error"

虽然我使文件可执行并使用了正确的 amd64 架构.

although I made the file executable and used the right amd64 architecture.

有没有人想出如何让电子图形用户界面在 docker 工作上更加天真?

Has anyone figured it out how to make electron GUI's naitively over docker work?

推荐答案

我会尽力在这个答案中帮助你 - 太长了，无法评论.

I will try to help you here in this answer - too long for comment.

我在我的 Win10 上尝试了你的 Docker 文件，但遇到了同样的问题.但是我通过添加所需的包并成功创建了 docker 映像来解决这个问题.这里是 Dockerfile

I tried your Docker file on my Win10 and with the same problems. But I figured it out by adding required packages and successfully created docker image. Here is Dockerfile

   FROM node:slim

   COPY . /usr/scr/app

   #RUN rm bdstart.sh
   RUN apt-get update

   # I think you need to install following 
   RUN apt-get -y install libgtkextra-dev libgconf2-dev libnss3 libasound2 libxtst-dev libxss1
   RUN npm install --save-dev electron

   RUN npm install

   CMD ["/usr/scr/app/start.sh"]

这是你的 start.sh

   #!/bin/sh
   ./node_modules/.bin/electron ./src

实际上我无权访问您的文件等，但是有了这个 DockerFile 能够毫无问题地创建 docker 映像.我还进入了 docker 容器并检查是否可以运行电子 - 工作.

Actually I don't have access to your files and so on, but with this DockerFile was able to create docker image without problems. I also went inside docker container and check whether is possible to run electron - worked.

如果你想进入容器，你只需要构建 docker 镜像.我已经通过(最简单的方式)按照命令(打开控制台Dockerfile所在的位置并运行):

If you want to go into container, you just need to build docker image. I have done it by (simplest way) following command (open console where Dockerfile is located and run):

   docker build -t test-image .

成功构建镜像后，您可以运行容器.如果有任何问题，我建议您使用 bash 入口点运行容器并调试失败的内容 - bash 将在您键入以下脚本的同一控制台中打开)

After Successfully build of image you can run container. If any problems I recommend you to run container with bash entrypoint and debug what fails - bash will open in the same console where you type following script)

   docker run -it test-image bash
