I created a Docker image from a Dockerfile to run a sample Meteor application. My Dockerfile is as follows.
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
My code uses 3 npm packages libxmljs, exec-sync and path which all got installed successfully. The Meteor application code and .meteor folder are copied to /home/app inside the docker image. But when I try to run the Meteor application, I get the following error.
sudo docker run -t -i 46630d0dc02e meteor
[[[[[ ~home/app ]]]]]
=> Started proxy.

I would greatly appreciate if anybody could explain the reason for the error and suggest a solution or workaround for running meteor application in docker container.
node image dosen't have ps command.
$ 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:/#
Use another base image which have ps command or install ps command on your image by adding RUN directive to your Dockerfile like below.
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
I tested it, and it works fine.
$ 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 ]]]]]

Give a try to phusion/passenger-docker. It is advertised to be a ready2use docker image for Meteor apps.
