Setup Openshift Environment with XL Release

One of the important things when starting to work in an OpenShift environment is to setup Domains, Applications and Gears. OpenShift provides a set of REST services that can be used to setup domains, applications, gears, etc and also deploy, configure applications. A lot of companies are now moving ahead on the path of using software on the cloud solutions and OpenShift is a popular one among developers who want to quickly deploy applications in lower environments for testing /showcase and tear down after use. XL Release is used for an overall release management and automation of all those activities that can truly be a machine interaction. This article shows XL Release's Webhook capability to interact with OpenShift APIs to create a domain and setup gears. Here's how you can go about it

• Open a browser and login into you XL Release instance.
• Create a new template
• Create a new phase
• You can create the first task as JSON Webhook
  • Task Name : Create Domain
  • URL : Openshift API
  • Method : POST
  • HTTP Body : contains domain name as JSON string
  • JSON Path Expression 1 : JSON Expression to parse the response from
  • Result 1 : ${appcreate_url} to Capture the JSON Expression 1 Value from captured response

• Create the second step as another JSON Webhook
  • Task Name : Create Application and Cartridges
  • URL : ${appcreate_url} is the value captured for the domain created from previous step
  • Method : POST
  • HTTP Body : contains application name and cartridges as JSON string
  • JSON Path Expression 1 : JSON Expression to parse the response from
  • Result 1 : ${app_url} to Capture the JSON Expression 1 Value from captured response

• Create a final third step as Script Step
  • Simple python code to print the captured value of ${app_url} pointing to the newly setup containers

• This is how it should look after all three have been created

• Now we can create a new Release from this Template and start the release
• This is how it looks after a successful run

•  Looking into the output of each of the steps
  • Step 1 - Create Domain -  Output shows the new domain created under open shift rhcloud

• • Step 2 - Create Application - Output shows the new application created under domain

• • Step 3 - Print Information - Finally printing the URL

    This is how you can make use of the XL Release web hook capability to connect and create a workflow for setting up your OpenShift cloud environment and do much more. Enjoy!!
