## Integration with Kubernetes
This Document decribes how to deploy Harbor on Kubernetes.
This Document decribes how to deploy Harbor on Kubernetes. It has been verified on **Kubernetes v1.6.5** and **Harbor v1.2.0**
### Prerequisite
* You need to download docker images of Harbor.
* Download the offline installer of Harbor from the [release](https://github.com/vmware/harbor/releases) page.
* Download the offline installer of Harbor v1.2.0 from the [release](https://github.com/vmware/harbor/releases) page.
* Uncompress the offline installer and get the images tgz file harbor.*.tgz.
* Load the images into docker:

Also the script need `openssl` to generate private key and certification, make sure you have a workable `openssl`.
There are some args of the python script:
- -f: Default Value is `../harbor.cfg`. You can specify other config file of Harbor.
- -k: Path to https private key. This arg can overwrite the value of `ssl_cert_key` in `harbor.cfg`.
- -c: Path to https certification. This arg can overwrite the value of `ssl_cert` in `harbor.cfg`.

These Basic Configuration must be set. Otherwise you can't deploy Harbor on Kubernetes.
- `make/harbor.cfg`: Basic config of Harbor. Please refer to `harbor.cfg`.
```
#Hostname is the endpoint for accessing Harbor,
#To accept access from outside of Kubernetes cluster, it should be set to a worker node.
hostname = 10.192.168.5

- `make/kubernetes/**/*.svc.yaml`: Specify the service of pods. In particular, the externalIP should be set in `make/kubernetes/nginx/nginx.svc.yaml`:

- `make/kubernetes/**/*.rc.yaml`: Specify configs of containers.
You need to specify the path to your images in all `*.rc.yaml`. example:
```
containers:
- name: nginx-app
# it's very importent that you need modify the path of image.
image: harbor/nginx

#### Advanced Configuration
If Basic Configuration was not covering your requirements, you can read this section for more details.
`./prepare` has a specify format of placeholder:
- `{{key}}`: It means we should replace the placeholder with the value in `config.cfg` which name is `key`.
- `{{num key}}`: It's used for multiple lines text. It will add `num` spaces to the leading of every line in text.
You can find all configs of Harbor in `make/kubernetes/templates/`. There are specifications of these files:
- `jobservice.cm.yaml`: ENV and web config of jobservice
- `mysql.cm.yaml`: Root passowrd of MySQL
- `nginx.cm.yaml`: Https certification and nginx config. If you are fimiliar with nginx, you can modify it.
