Install additional apt-get packages in docker image if specified

[ckiely91]

Added additional option to mup.js to specify an array of apt-get package names. Based on this gist.

This will be a very useful feature to install packages such as graphicsmagick. Let me know if there are ways I can improve this!

We already have a proposal to add hooks, #65
Which seems like a more generic feature. @arunoda @mnmtanish what do you think?

This would be very useful to install packages like graphicsmagick

Just wondering the status for the PR, any update?

[madushan1000]

The recommended way to add new packages to the docker image is to build one of your own using meteorhacks/meteord base image and use that in the deployment.

[arunoda]

I hope we allow to change the docker image.
meteord is the base. But you could use any docker image with your own deps.
@madushan1000 I think we need to document it if it's not done.

[jbg77]

Yes that I've done and many other people did, two methods:
-by cloning repo, then upload your image on docker hub
-by fork meteord repo, then link you github account to your docker account, and active autobuild

@ckiely91 Thanks for working on this. Some base images use a different package manager, such as the alpine image. I would prefer a more general purpose solution where there is an array of commands in the config to run when building the docker image.

I am currently using a manual "post deploy" thing to add my packages:

docker exec -it myapp bash
apt install pdftk

I have been searching for ways to do it automatically using configuration options in MUP and ended up here. Is there a way to automate that process?

[zodern]

@stefanve the best way right now is to create a custom docker image with pdftk already installed.

@stefanve an easier way will be available in the next version: #362.
