Jenkinsfile

/*
 * This is a vanilla Jenkins pipeline that relies on the Jenkins kubernetes plugin to dynamically provision agents for
 * the build containers.
 *
 * The individual containers are defined in the `jenkins-pod-template.yaml` and the containers are referenced by name
 * in the `container()` blocks. The underlying pod definition expects certain kube Secrets and ConfigMap objects to
 * have been created in order for the Pod to run. See `jenkins-pod-template.yaml` for more information.
 *
 * The cloudName variable is set dynamically based on the existance/value of env.CLOUD_NAME which allows this pipeline
 * to run in both Kubernetes and OpenShift environments.
