Upload Components/Application templates from Ystia Forge

The Ystia Forge at https://github.com/ystia/forge provides components and application templates that can be uploaded in Alien4Cloud, to be deployed by Yorc.

For example, it provides:

• Cloudera,
• Log analysis applications based on Elastic Search
• Kafka
• Kubernetes allowing you to create a Kubernetes cluster in your datacenter.
• etc...

See the list of available components and application templates at https://github.com/ystia/forge/tree/v3.0.0-milestone.1/org/ystia.

Here, we will upload a sample application template, Welcome, deploying an HTTP server.

To upload this application template in Alien4Cloud, you could generate zip archives and upload these archives in Alien4Cloud.
