Using a BuildConfig to build Hive

When deployed to an OpenShift server, Hive can be automatically built and deployed using a BuildConfig and a GitHub Webhook.

To setup the BuildConfig:

Modify the config/builconfig/hive-buildconfig.yaml manifest by adding a secret string in the placeholder for a webhook secret. If setting up for your own fork, replace the git repository URL with your own fork's URL.
Apply the manifests in config/buildconfig/ to the namespace where the Hive operator is installed (typically the hive namespace).

Setup a deployment trigger using the oc set triggers command:

oc project hive
oc set triggers deployment/hive-operator --from-image=hive:latest --containers hive-operator

Obtain the webhook URL for the BuildConfig by using oc describe
```
oc project hive
oc describe buildconfig/hive
```
The description will contain a Webhook GitHub URL, copy that URL and replace the <secret> placeholder with the secret string you entered in the buildconfig manifest.
Go to the GitHub repository, click on Settings and navigate to Webhooks.
Click on Add Webhook
Enter the URL from the webconfig in the Payload URL field
Select application/json in Content Type
Leave Secret blank
If not using valid certificates for your cluster, select to Disable SSL Verification
Click on Add webhook
