New Approach
Pros:
All components can be installed - LP, DP and Core service's
Easy customization of all components by forking the desired repository
Spin up a Jenkins instance and start building on your own
Everything is a Jenkinsfile
Version control of build and deploy process using Jenkinsfile
Visibility on how Sunbird does build and deploy by just looking at the Jenkinsfiles
Docker images can be stored in any registry and artifacts in azure blobs or locally on Jenkins
Seamless and quick rollbacks
All features, updates and process of Sunbird available to end users
85% of ansible variables refactored
Only about 100 odd variables need to initialized for entire setup
600 variables refactored to about 100 odd variables
Every comfiguratuok can be overridden based on requirements
Easy upgrades by just using the latest GA certified tag by one click build and deploy.
Total control and content and frameworks
Minimal hardware - Just 10 servers for entire setup
Easy scaling of infrastructure - All through ansible inventory and Jenkinsfiles
Production ready setup and easy promotion of code from dev to production
Anyone can run a full stack sunbird with home brewed customizations
Cons:
Takes a day's effort
Medium level technical skills required to setup
Only azure blobs supported to store artifacts at this point of time (can be skipped if stored locally on Jenkins)
How this was done?
Converted every freestyle Jenkins job to a Jenkinsfile
Published every Jenkinsfile along with ready to use job configurations
Constant and non mandatory variables were set to its default which is as per standards
Setting up Jenkins and all required jobs using 3 scripts.
Mandatory variables provided in a standard template along with detailed descriptions which needs to be filled
Detailed documentation on how to setup
How will an adopter run this process?
Clone sunbird-devops
Run jenkins server, plugins and jobs script
Fill mandatory ansible variables
Start building the jobs and deploy to servers
Create a framework and start using Sunbird
How will an adopter upgrade?
Clone sunbird-devops
Run the same jenkins scripts which will upgrade existing jobs and create new jobs as per release
Add / remove variables as per changelog provided with every release
