Thanks @FedeG.
Have you tested both dockerfile and the docker-compose file configuration to work well?

[lirantal]

I tested it, seems to be ok including live reload for dev environment.

Actually FYI I tested the dev docker updates, haven't yet tested the production one.

@FedeG can you outline the differences from the dev docker setup? is it just the NODE_ENV defaulting to production in the dockerfile?

[FedeG]

Differences:

• In Dockerfile:
  • Simplify some commands
  • Add --production to npm install
  • NODE_ENV defaulting to production
  • Remove expose for debug port (remove EXPOSE 5858:5858)
• In docker-compose.yml:
  • Change ports (remove 3000, 5858 and 35729 and add 8443)
  • NODE_ENV defaulting to production
  • Remove code volumes (change ./:/opt/mean.js to /opt/mean.js)
  • Remove expose db port (remove 27017 in mongo container)
• Update documentation for deployment in production

Sounds good.
Thanks @FedeG.
