# 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, "~> 0.6.0"}

  ]

end

```



## Configure



Mandrag doesn't require configuation, it'll introspect the parent mix config to derive configuration, and use it's own built-in [Dockerfile](tk), but you can override those values as seen below.



```elixir

config :mandrag,

  # The name of the app and release. Defaults to the :app key in the parent mix project.

  app: :app_name,

  # The docker repo to push to. Defaults to `docker/app_name`.

  docker_repo: docker/another_name,

  # The path to the Dockerfile to be used.  Defaults to the Dockerfile inside this package.

  dockerfile_path: Dockerfile,

  # A map of values that are translated to `--build-arg` arguments.

  docker_build_args: %{key: "value"}

```



TODO:

- Add dockerfile export

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