Ciinabox2 EC2 Agent Build Caching

Jenkins Agent Build Caching

With the latest ciinabox2 0.8.0 and the latest ciinabox Jenkins agent AMIs releases Jenkins agents can now mount a EFS volume to cache build data. This can provide a performance boost with builds pulling in large amount of dependencies or cloning large repositories.

To setup the cache volume on the EC2 agent follow these steps:

1. add the initScript key to your EC2 plugin configuration with the mount command using the new cache EFS access point to the /efs/cache directory

   jenkins:
   clouds:
   - amazonEC2:
       cloudName: "linux"
       templates:
       - ami: "${/ciinabox/ci2/agent/linux/ami}"
           initScript: |
               sudo mount -t efs -o tls,accesspoint=${/ciinabox/ci2/agent/cache-ap} ${/ciinabox/ci2/agent/efs} /efs/cache
   

2. setup your pipeline to utilise the cache directory

   pipeline {
       agent {
           label 'linux'
       }
       stages {
           stage('build') {
               steps {
                   dir('/efs/cache') {
                       sh 'pwd'
                   }
               }
           }
       }
   }
