Hi guys, So I've spent a few days reading tutorials and posts and watching videos on Docker. It looks amazing. I'm not currently using it, but I want to. I have a NodeJS app with a MongoDB instance that I want to: - Deploy - Have CI deploy it - Use docker for both local and production instance (i.e. the same). I want to use DigitalOcean droplets. However, reading their tutorials, I keep running into Dokku, which is a small Heroku clone. How does Dokku fit into Docker? Dokku seems to rely on Heroku-buildpacks for extra features. I.e. you want a Mongo instance, just install this plugin. Is this what I want? I want to install some other stuff on the container (Imagemagick, libvips etc), but there are no buildpacks for that. Can't I just write my own handwritten Dockerfile? I'm unsure where to start. Can anyone point me in the right direction?
