This is unnecessary when the Jenkins controller runs in the same Kubernetes cluster, but can greatly simplify setup when agents are in an external cluster and the Jenkins controller is not directly accessible (for example, it is behind a reverse proxy or a ingress resource). If you check WebSocket then agents will connect over HTTP(S) rather than the Jenkins service TCP port. Google Service Account from private key (GKE authentication).Secret text (Token-based authentication) (OpenShift).In order to do that, you will open the Jenkins UI and navigate to Manage Jenkins -> Manage Nodes and Clouds -> Configure Clouds -> Add a new cloud -> Kubernetes and enter the Kubernetes URL and Jenkins URL appropriately, unless Jenkins is running in Kubernetes in which case the defaults work.

A running Kubernetes cluster 1.14 or later.Configuration on Google Container Engine.Features controlled using system properties.It is not required to run the Jenkins controller inside Kubernetes. Tested with jenkins/inbound-agent, see the Docker image source code.

JENKINS_URL : Jenkins web interface url.

For that some environment variables are automatically injected: The plugin creates a Kubernetes Pod for each agent started, and stops it after each build.Īgents are launched as inbound agents, so it is expected that the container connects automatically to the Jenkins controller.
