Question

我从Dockerfile创建了一个Docker镜像来运行示例Meteor应用程序。我的Dockerfile如下。

FROM node:0.10.30

RUN curl https://install.meteor.com/ | sh
RUN npm install -g meteorite

RUN cd /tmp && npm install libxmljs exec-sync path
RUN mkdir -p /home/app && cp -a /tmp/node_modules /home/app/

ADD src/ /home/app/

WORKDIR /home/app

ENV PORT 3000
EXPOSE 3000

我的代码使用3 npm包libxmljs，exec-sync和path，这些都已成功安装。 Meteor应用程序代码和.meteor文件夹将复制到docker镜像内的/home/app。但是当我尝试运行Meteor应用程序时，我收到以下错误。

sudo docker run -t -i 46630d0dc02e meteor
[[[[[ ~home/app ]]]]]

如果有人能够解释错误的原因并建议在docker容器中运行meteor应用程序的解决方案或解决方法，我将不胜感激。

node图片没有ps命令。

$ docker run -t -i node:0.10.30 bash
root@1d5c5e3ec748:/# ps
bash: ps: command not found
root@f1d530730c37:/# find / -name ps -type f
root@f1d530730c37:/#

通过向您的Dockerfile添加ps command指令，在图像上使用另一个具有ps或安装RUN命令的基本映像。

FROM node:0.10.30

# Install ps command
RUN apt-get update
RUN apt-get install procps

RUN curl https://install.meteor.com/ | sh
RUN npm install -g meteorite

RUN cd /tmp && npm install libxmljs exec-sync path
RUN mkdir -p /home/app && cp -a /tmp/node_modules /home/app/

ADD src/ /home/app/

WORKDIR /home/app

ENV PORT 3000
EXPOSE 3000

我测试了它，它工作正常。

$ docker run -t -i nacyot/meteor bash
root@0b56bf009532:/home/app/test# meteor create test
root@0b56bf009532:/home/app/test# cd test
root@0b56bf009532:/home/app/test# meteor 
=> App running at: http://localhost:3000/
root@0b56bf009532:/home/app/test# meteor
[[[[[ ~home/app/test ]]]]]

=> Started proxy.
=> Started MongoDB.     
=> Started your app.   

=> App running at: http://localhost:3000/

尝试phusion/passenger-docker。它被宣传为Meteor应用程序的ready2use docker镜像。

由于无法运行ps ax错误，无法在Docker容器中运行Meteor应用程序
