避免在 Jenkins Job DSL API 上重复

Question

I´m configuring a couple Jenkins jobs using Jenkins Job DSL Plugin , and in the steps section for my two jobs it´s almost the same, just has to change one value " builder " by " couchbase ".

For now seems like I´m breaking DRY and I´m duplicating a lot of code. Since I´m pretty newby on DSL I´m not quite sure if the API allow create a sort of generic code to avoid duplicate steps as I´m doing.

job("images/builder") {
   concurrentBuild()
   triggers {
      githubPush()
 }

scm {
    git {
        remote {
            github("aws", "https", "github.dev.global.com")
            credentials('***********')
        }
    }
}
steps {
    shell('export AWS_DEFAULT_REGION=eu-west-1')
    shell('$(aws ecr get-login --region eu-west-1)')
    shell('docker build -t builder -f ./images/builder/Dockerfile .')
    shell('docker tag -f builder:latest **********.dkr.ecr.eu-west-1.amazonaws.com/builder:latest')
    shell('docker push **********.dkr.ecr.eu-west-1.amazonaws.com/builder:latest)')
}

}

job("images/couchbase") {
   concurrentBuild()
    triggers {
    githubPush()
   }

scm {
    git {
        remote {
               github("aws2", "https", "github.dev.global.com")

            credentials('****************')
        }
    }
}
steps {
    shell('export AWS_DEFAULT_REGION=eu-west-1')
    shell('$(aws ecr get-login --region eu-west-1)')
    shell('docker build -t builder -f ./images/couchbase/Dockerfile .')
    shell('docker tag -f builder:latest ********.dkr.ecr.eu-west-1.amazonaws.com/couchbase:latest')
    shell('docker push **********.dkr.ecr.eu-west-1.amazonaws.com/couchbase:latest)')
}

}

If it's as simple as the same steps for two named projects, a loop would suffice:

String[] names = ["builder", "couchbase"]

names.each {
  job("images/" + it) {
    concurrentBuild()
    triggers {
      githubPush()
    }

    scm {
      git {
        remote {
          github("aws2", "https", "github.dev.global.com")

          credentials('****************')
        }
      }
    }
    steps {
      shell('export AWS_DEFAULT_REGION=eu-west-1')
      shell('$(aws ecr get-login --region eu-west-1)')
      shell('docker build -t builder -f ./images/' + it + '/Dockerfile .')
      shell('docker tag -f builder:latest ********.dkr.ecr.eu-west-1.amazonaws.com/' + it + ':latest')
      shell('docker push **********.dkr.ecr.eu-west-1.amazonaws.com/' + it + ':latest)')
    }

  }
}

If you want something more complex, take a look at these examples , specifically the job builder class and usage of it
