Error: listen EACCES 0.0.0.0:80

I'm getting the following error when launching the container with:

sudo docker run --rm   -e ROOT_URL=http://testsite.com   -v $(pwd):/home/meteor/src   -e MONGO_URL=mongodb://172.17.0.2:27017/appdb   ulexus/meteor

That is correct; now that Meteor does not allow running as root, you may not bind to port 80. With a container, that should not normally be a problem. Just set the PORT environment variable to some other port (>1024), and Meteor will bind to that port instead. If you wish Docker to expose that port as port 80 externally, you may do so easily, as well.

In your case, I would modify your execution thus:

docker run --rm \
  -e MONGO_URL=mongodb://172.17.0.2:27017/appdb \
  -e ROOT_URL=http://testsite.com \
  -e PORT=3000 \
  -p 80:3000 \
  -v $(pwd):/home/meteor/src \
  ulexus/meteor

I see. It worked like a charm!
