# Mandrag

Deploy Elixir releases to [Kubernetes](https://kubernetes.io/) via [Distilerry](https://github.com/bitwalker/distillery) and [Helm](https://helm.sh/)

## Requirements
Mandrag expects that you have docker, kubectl and helm binaries installed and configured.  It also expects to you have a helm chart in the `chart` directory.

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `mandrag` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:mandrag, "~> 0.5.1"}
  ]
end
```

## Configure

Mandrag doesn't require configuation, it'll introspect the parent mix config to derive configuration, but you can override those values as seen below.

```elixir
config :mandrag,
  # Defaults to the name of the mix project app
  app: :app_name,
  # You can also specify a docker repo, it defaults to the value speficied to `docker/app_name`
  docker_repo: docker/app_name
```

TODO:
- Add default Dockerfile and Helm chart for zero conifg standup.  (or mabye just create a [draft](https://draft.sh/) pack?)
