Module 1 - Review the setup

In this module, we will show you how to do a demo of IaC (Infrastructure as Code) with F5 solutions:

  • We will use GitLab to host our application definition and also services tied to it : ADC and Web Application Firewall services
  • We will trigger our CI/CD pipeline by updating our Gitlab repo
  • We will monitor how our application is deployed.
  • We will ensure that the relevant ADC services are deployed on our BIG-IP

To do this demo, we need to get a proper understanding of the setup.

Through Module1, you’ll review the overall setup and be able to trigger a demo of IaC

You have a preso you can use/review to see the overall workflow, Here is the Preso.

Here is the workflow of the solution:

  1. We leverage a GitLab repo called my-webapp-ci-cd-demo that contains our app definition and the ADC Services tied to it.
  2. We update this repo to trigger a WebHook that will ask our CI Server to retrieve this repo and process its jenkinsFile
  3. Our CI server will do the following:
  • retrieve the repo
  • deploy the app based on its definition
  • test that the app is up and running based on the tests defined in the repo
  • review the ADC services definition in the repo and ensure its fine.
  • Update another repo called ADC-Services to add its ADC service definition and the tests to validate its proper deployment
  1. Since we updated our ADC-Services repo on GitLab, it will also send a WebHook to Jenkins to trigger another pipeline
  2. Our CI server will execute the relevant pipeline that will do the following:
  • review the commit log to know which app has been added
  • find in which cluster this app has been added
  • review and put all the app services for this cluster in a single AS3 declaration
  • Test this tenant definition against the relevant cluster
  • Deploy this declaration
  • Trigger the tests tied to this app through BIG-IP to make sure it is still successfull
