# Draft: Streamlined Kubernetes Development

[![Build Status](https://ci.deis.io/buildStatus/icon?job=Azure/draft/master)](https://ci.deis.io/job/Azure/job/draft/job/master/)

_NOTE: Draft is experimental and does not have a stable release yet._

Draft handles the heavy lifting involved in taking source code and deploying it to Kubernetes:

- Builds a container image from application source code
- Pushes the image to a registry
- Packages a [Helm][] chart from application source code
- Installs the chart to Kubernetes, deploying the application

## Usage

### Dependencies

- Draft will need a running Kubernetes cluster to deploy your app. [Minikube](https://github.com/kubernetes/minikube) is a great free option.
- Draft expects [Helm](https://github.com/kubernetes/helm) to be installed on your Kubernetes cluster. Download [`helm` v2.4.x](https://github.com/kubernetes/helm/releases) and
do a `helm init` first, as described in [Installing Helm][].
- Draft needs to push images to a Docker registry, so you'll need to configure Draft with your Docker registry credentials. If don't already have one, you can create a Docker registry for free on either [Dockerhub.com](https://dockerhub.com) or [Quay.io](https://quay.io).

### Install Draft

Because Draft is currently experimental, there is no stable release out yet and users are expected
to be using the latest build of Draft for testing. Canary releases of the Draft client can be found
at the following links:

 - [Linux amd64](https://azuredraft.blob.core.windows.net/draft/draft-canary-linux-amd64.tar.gz)
 - [macOS amd64](https://azuredraft.blob.core.windows.net/draft/draft-canary-darwin-amd64.tar.gz)
 - [Windows amd64](https://azuredraft.blob.core.windows.net/draft/draft-canary-windows-amd64.tar.gz)

Unpack the Draft binary and add it to your PATH and you are good to go!


### Configure Draft

To install the server-side of Draft, use `draft init` with your credentials to let Draft communicate
with a Docker registry by using the following command:

```
$ draft init --set registry.url=docker.io,registry.org=changeme,registry.authtoken=changeme
```

The auth token field follows the format of Docker's X-Registry-Auth header.
For credential-based logins such as Docker Hub and Quay, use:

```
$ echo '{"username":"jdoe","password":"secret","email":"jdoe@acme.com"}' | base64
```

For token-based logins such as Google Container Registry and Amazon ECR, use:

```
$ echo '{"registrytoken":"9cbaf023786cd7"}' | base64
```
