sansarip/phoenix-builder repository overview

⁠About

At this point in time - Aug. 8, 2019 - the majority of the Phoenix s2i builder images I've seen around on Dockerhub are either really out-dated OR (inclusive or btw) just plain don't work. So, I decided to make my own.

This image is pretty simple, and uses the official Elixir Alpine docker image as its base rather than the openshift/base-centos7 image. As a result, it's actually much smaller than the aforementioned OpenShift base image.

Source:

https://github.com/sansarip/phoenix-builder⁠

⁠Usage

1. Pull the image docker pull sansarip/phoenix-builder

2. Given you have the s2i executable available to you which you can find here⁠, then you can simply run s2i build <your phoenix app dir> sansarip/phoenix-builder <app name>

3. All set! You've now generated a new Docker image with your src code embedded in it, and you can run it with docker run -it -p 4000:4000 <app name>

Your application should be listening on port 4000 now. Go get 'em, champ!

⁠Runtime Env Vars

If you expect your final application to accept runtime env vars, then you should pull the image with theruntime-env tag; this version of the builder image will recompile your app on each run, thereby accepting Docker runtime env vars.
