# APPR Command Line Tool
[CLI commands overview](Documentation/quick-start.md)

## Install the Helm Registry Plugin

First, Install the latest [Helm release](https://github.com/kubernetes/helm#install).

If you are an OSX user, quickstart with brew: `brew install kubernetes-helm`

Next download and install the registry plugin for Helm.

### OSX

```
wget https://github.com/cn-app-registry/appr-cli/releases/download/v0.3.7-dev/registry-appr-v0.3.7-dev-osx-x64-helm-plugin.tar.gz
mkdir -p ~/.helm/plugins/
tar xzvf registry-appr-v0.3.7-dev-osx-x64-helm-plugin.tar.gz -C ~/.helm/plugins/
```

### Linux

```
wget https://github.com/cn-app-registry/appr-cli/releases/download/v0.3.7-dev/registry-appr-v0.3.7-dev-linux-x64-helm-plugin.tar.gz
mkdir -p ~/.helm/plugins/
tar xzvf registry-appr-v0.3.7-dev-linux-x64-helm-plugin.tar.gz -C ~/.helm/plugins/
```

### Windows

```
wget https://github.com/cn-app-registry/appr-cli/releases/download/v0.3.7-dev/registry-appr-v0.3.7-dev-win-x64-helm-plugin.tar.gz
mkdir -p ~/.helm/plugins/
tar xzvf registry-appr-v0.3.7-dev-linux-x64-helm-plugin.tar.gz -C ~/.helm/plugins/
```

Note: You must have bash in your path and change the `registry/plugin.yaml` execution to call `bash -c $HELM_PLUGIN_DIR/appr.sh`


## Deploy Jenkins Using Helm from the Quay Registry


```
helm registry version app.quay.io
```

Output should be:
```
Api-version: {u'appr-api': u'0.X.Y'}
Client-version: 0.X.Y
```

### Install Jenkins

```
helm init
helm registry list app.quay.io
helm registry install app.quay.io/helm/jenkins
```

## Create and Push Your Own Chart

First, create an account on https://app.quay.io (staging server) and login to the CLI using the username and password

Set an environment for the username created at Quay to use through the rest of these instructions.

```
export USERNAME=philips
```

Login to Quay with the Helm registry plugin:

```
helm registry login -u $USERNAME app.quay.io
```

Create a new Helm chart, the default will create a sample nginx application:

```
helm create nginx
```

Push this new chart to Quay and then deploy it from Quay.

```
cd nginx
helm registry push --namespace $USERNAME app.quay.io
helm registry install app.quay.io/$USERNAME/nginx
```


# appr-server

APPR implements a registry for storing Kubernetes application manifests that attempts to reuse as much knowledge from the rest of the Linux container ecosystem as possible.

Differentiating features include:

- A protocol and data model that can more easily be implemented by pre-existing container registries
- This includes a common API for uploading, downloading, and searching for applications
- The reuse and integration with many elements from [OCI](https://www.opencontainers.org)
- Content addressable manifest scheme for security, signing, and non-trusted mirroring
- Reuse of common data structures such as Descriptors
- Unification of Manifest Lists as the means of content negoitation for both Images and Applications

## Getting started

1. git clone https://github.com/cn-app-registry/appr-server.git && cd appr-server
2. pip install -e . && pip install gunicorn
3. Run the appr-server on port 5000 `gunicorn appr.api.wsgi:app -b :5000`
or "./run-server"
4. See the [curl-based examples](Documentation/test.sh)

## Architecture at a glance

There are two top-level objects:

- Package: metadata describing an application
- Blob: a gzipped tarball of the package encoded in base64

Packages are primarily indexed by 3 notable fields:

- package-name: it follows container-image format: `namespace/name`.
- release: it's the version of the package, immutable it can be viewed as an alias to a digest
- mediaType: the format of the package formats (eg: docker-compose, dab, helm, kpm)

Data storage is specified by the `STORAGE` environment variable. The following are supported:

- `filesystem` (default)
- [`etcd`](https://github.com/coreos/etcd)
- [`redis`](https://github.com/antirez/redis)

## Demo using using [Helm](https://github.com/kubernetes/helm) charts

### Publish a chart

Create and encode the chart tarball

```
~/charts/elasticsearch $
tar czvf ../elastichart.tar.gz Chart.yaml manifests README.md
cat ../elastichart.tar.gz | base64 -w 0

```

POST the chart to APPR

```
curl -XPOST http://localhost:5000/api/v1/packages/myname/elasticsearch -d '
{
"blob": "H4sIAP3mAFgAA....",
"release": "2.2.1",
"media_type": "helm"
}'
```

### Pull the chart

Find the digest from the package-name/release/media-type

```
curl -XGET http://localhost:5000/api/v1/packages/myname/elasticsearch/2.2.1/helm
{
"channels": [],
"content": {
"digest": "72ed15c9a65961ecd034cca098ec18eb99002cd402824aae8a674a8ae41bd0ef",
"mediaType": "application/vnd.appr.package.helm.v1.tar+gzip",
"size": 583,
"urls": []
},
"created_at": "2016-11-16T17:13:07.806579",
"mediaType": "application/vnd.appr.package-manifest.helm.v1.json",
"package": "myname/elasticsearch",
"release": "2.2.1"
}

```

Fetch the blob

```
curl -XGET \
http://localhost:5000/api/v1/packages/myname/elasticsearch/blobs/sha256/72ed15c9a65961ecd034cca098ec18eb99002cd402824aae8a674a8ae41bd0ef \
