Example Jenkins pipeline that harden a Docker Image

ise-hardened-docker-example ======

This is an example repo of docker image hardening Jenkins Pipeline.

How to setup a new CICD Pipeline for new Docker Image ------

Step1, Prepare git repo to host jenkins scripts:

1. Duplicate this GitHub Repo, give it a name like ise-hardened-${your-docker-image-descriptor}
2. Update Dockerfile, put your source docker image at FROM, update other metadata.

Step2, Setup Jenkins pipeline in Consol

1. Go to Jenkins Console -> New Item -> Choose Pipeline or Multibranch Pipeline project.

2. Configure Parameters:

   • Click This Project is parameterized
   • Add artifactoryURL, artifactoryRegistry, ... parameters. Basically these parameters are the arguments defined in our jenkins shared library - hardenDockerImage.groovy. For full list of parameters, please check https://github.com/GSA/ise-jenkins-shared-library/blob/main/vars/hardenDockerImage.groovy

3. Configure SCM:

   • Pipeline -> Pipeline script from SCM -> Git, fill in Git URL, credentials, branch. You can define a parameter gitBranch and use */${gitBranch} in Branch Specifier input box -> set Script Path Jenkinsfile -> Uncheck Lightweight Checkout (otherwise you cannot use gitBranch parameter to control what branch you want to build from.

Step3, Import Jenkins Shared Library into Jenkins System

Jenkins -> Manage Jenkins -> Configure System -> Search: Global Pipeline Libraries

Fill in https://github.com/GSA/ise-jenkins-shared-library url, it will load the latest jenkins shared library into the runtime, so you can start using those libraries in Jenkinsfile. Check "Load Implicitly" (if not check, you need to manually declare @Library("${LibraryName}") at begin of your Jenkinsfile).
