CI Workflow and Architecture

Central Build-box Architecture:

• Repositories on https://git.randomhouse.com

• Runners installed on Build Boxes

• Build boxes watch for changes, and executes build instructions as needed

• Builds occur within temporary directory on build box

• Resulting "Productionalized" code remotely deployed onto destination servers

• Destination Servers serves application

This is the preferred architecture

• Increased security

• Decreased runner maintenance

• Build processing load on dedicated resources

• Promotes 'clean deploy' on destination servers

Local Runner Architecture:

• Repositories on https://git.randomhouse.com

• Runners installed on destination servers

• Build occurs locally in temp directory on destination server

• "Productionalized" code moved locally into proper location on server

!!! Not the preferred approach !!!

• Less Secure

• Must maintain each destination runner

• Destination servers "get dirty" during build

• Improper separation of automated tools

  • Red Hat Satellite Server for Software package dependencies

  • Server configuration managed via SaltStack

• Does not promote proper separation of Application from Operating System

• Troubleshooting more complex
