# elixir-buildpacks
A collection of buildpacks to build images of elixir projects
1. `erlang-runtime`
1. `elixir-runtime`
1. `mix-release` download project dependencies and create an [Elixir Release](https://elixir-lang.org/blog/2019/06/24/elixir-v1-9-0-released/#releases)
1. `elixir` meta buildpack that define the order in which buildpack run
In addition `rg.nl-ams.scw.cloud/carlo-colombo/elixir-builder` is a builder based on `ubuntu:bionic` including the 4 buildpacks.
This stack support `org.cloudfoundry.stacks.cflinuxfs3` (`cloudfoundry/cnb:cflinuxfs3`) and `io.github.carlo-colombo.elixir-builder`
### Umbrella applications
To create a release from an umbrella application run from the root of the application defining the release to build with the `RELEASE` env variable
```bash
pack build dashboard \
--path . \
--builder rg.nl-ams.scw.cloud/carlo-colombo/elixir-builder \
-e RELEASE=dashboard -e SECRET_KEY_BASE=asdadasdasd
```
Note: is not supported to build individual release from the app folder, as in app dependency and configuration would be outside of the directory passed to `pack`.
### Know limitations
- It at least partially support `phoenix`, it requires to pass in `SECRET_KEY_BASE` as environment variable. For example
```bash
pack build dashboard \
--path . \
--builder rg.nl-ams.scw.cloud/carlo-colombo/elixir-builder \
-e DEBUG=1 \
-e SECRET_KEY_BASE="$(mix phx.gen.secret)"
```
## How to build an image with pack
### Using the builder image
```bash
pack build \
--path \
--builder rg.nl-ams.scw.cloud/carlo-colombo/elixir-builder
```
### Using individual buildpacks
```bash
pack build \
--path \
--buildpack ./elixir/ \
-b ./elixir-runtime/ \
-b ./erlang-runtime/ \
-b ./mix-release/ \
--builder rg.nl-ams.scw.cloud/carlo-colombo/elixir-builder
```
## How to create the builder image
```bash
cd elixir-builder
./build.sh
```
It create an image on the local docker named `rg.nl-ams.scw.cloud/carlo-colombo/elixir-builder`
