Introduction

A common Jenkins and Kubernetes integration pattern is to run Jenkins on Kubernetes and manage its installation with Helm. Helm handles the Kubernetes resource packaging, while Jenkins handles the CI/CD workflows, agents, and deployment logic.

Use Helm to Install or Upgrade Jenkins

Helm is useful here because Jenkins requires several Kubernetes resources such as deployments, services, persistence configuration, and plugins or values-based customization.

A Helm-based workflow usually looks like this:

helm repo add jenkins https://charts.jenkins.io
helm repo update
helm install my-jenkins jenkins/jenkins

That gives you a Kubernetes-managed Jenkins deployment that you can version and reconfigure through Helm values.

Let Jenkins Use Kubernetes for Dynamic Agents

Once Jenkins is running on Kubernetes, the next integration step is usually dynamic build agents. Jenkins can request ephemeral agent pods for builds instead of relying only on static workers.

That pairing is one of the main reasons Jenkins and Kubernetes work well together:

• Jenkins coordinates the jobs
• Kubernetes supplies elastic execution environments

Keep Helm and Jenkins Responsibilities Separate

Helm is for packaging and managing the Jenkins deployment in Kubernetes. Jenkins is for orchestrating builds and delivery workflows. Confusing those responsibilities leads to messy automation.

A clean design is:

• Helm manages Jenkins itself as an application on the cluster
• Jenkins jobs may later deploy other applications, possibly with Helm too

Common Pitfalls

• Treating Helm as the CI engine instead of as the Kubernetes package manager.
• Running Jenkins on Kubernetes without planning for persistence and plugin configuration.
• Forgetting that dynamic agents need correct Kubernetes access and pod templates.
• Mixing Jenkins deployment management with application deployment logic in one unclear layer.
• Installing Jenkins successfully but never validating how builds actually run on the cluster.

Summary

• Helm is a practical way to install and manage Jenkins on Kubernetes.
• Jenkins and Kubernetes integrate well when Jenkins uses Kubernetes-backed dynamic agents.
• Helm manages the Jenkins deployment; Jenkins manages CI/CD workflows.
• Keep infrastructure packaging and build orchestration responsibilities distinct.
• A successful integration is more than installation; it includes verified build execution on the cluster.
