If I need to restart Jenkins due to installing a plugin for instance the slaves are never turned on. I am using Google Compute Engine. I followed this tutorial:
https://cloud.google.com/tools/repo/push-to-deploy
Using this to create the Jenkins server:
export PASSWORD=<password>export PROJECT_ID=<project-id>gcloud compute \ instances create bitnami-jenkins \ --project ${PROJECT_ID} \ --image-project bitnami-launchpad \ --image bitnami-jenkins-1-587-0-linux-debian-7-x86-64-image \ --zone us-central1-a \ --machine-type n1-standard-1 \ --metadata "bitnami-base-password=${PASSWORD}" \"bitnami-default-user=user" \"bitnami-key=jenkins" \"bitnami-name=Jenkins" \"bitnami-version=1-587-0" \"bitnami-url=//bitnami.com/stack/jenkins" \"bitnami-description=Jenkins." \"startup-script-url=https://dl.google.com/dl/jenkins/p2dsetup/setup-script.sh" \ --scopes "https://www.googleapis.com/auth/userinfo.email" \"https://www.googleapis.com/auth/devstorage.full_control" \"https://www.googleapis.com/auth/projecthosting" \"https://www.googleapis.com/auth/appengine.admin" \ --tags "bitnami-launchpad"Here is an image of how Jenkins look after restart:
