Elixir
For packaging elixir we depend on elixir mix releases
These releases take an erlang distribution, dependencies, and erlang code as input. From the input mix release will create a unified directory with everything needed to run the application. Including flags for VM tuning and bash startup scripts.
Releases are listed in the platform_umbrella/mix.exs in the &releases/0 method. There we specify overrides for configs to use in the release, dependencies, and steps of creating the release.
To run a release you choose the build profile you want (likely prod if this is for real use). Then we need to compile and release.
MIX_ENV= <<YOUR_ENV>> mix do clean, compile, release <<REL_NAME>> --overwrite
Docker Based
Control server and HomeBase also include CSS and JS that need to be packaged up for use on the browser. Those static files then get compressed and digested. All of this gets handled in the Dockerfile in platform_umbrella. That takes in arguments for what binary to run and what release to build like this:
docker build --build-arg RELEASE=home_base \
--build-arg BINARY=bin/home_base \
-t battery/home:MY_TEST_TAG \
platform_umbrella
This will need to all be pushed to a publicly accessible but authenticated docker container host. However that is not yet ready.
