On Premise Kubernetes
If you are using kubernetes we highly recommend you use one of the managed cloud providers as this comes with lots of additional features like:
- container registries and bucket storage
- IAM and workload identity (e.g. so kubernetes Service Accounts can be assigned roles to be able to read/write to certain buckets or container registries)
However sometimes you need to run kubernetes on your premise. Longer term we hope the cloud providers can run their managed kubernetes and associated infrastructure on your premise too so you get to reuse the same storage + IAM anywhere. But until then, this guide is intended to get you started installing Jenkins X on a vanilla kubernetes cluster on premise.
Here are some detailed instructions on getting JX running in a Lab Environment.
The following are the prerequisites of your on-premise kubernetes cluster:
If you are going the bare metal route you could try these instructions
You need to be able to connect to your kubernetes cluster via kubectl so that you can run commands like:
kubectl get ns kubectl get node
To view the namespaces and nodes respectively.
To use Jenkins X we need ingress to work. This means being able to create a kubernetes
Ingress resource with a domain name which can be resolved outside of kubernetes to network into kubernetes services.
Jenkins X installs
nginx which has a
Service to implement ingress. But the underlying kubernetes platform needs to implement the load balancing network and infrastructure. This comes out of the box on all public clouds.
With an on-premise kubernetes cluster you need to install something like MetalLB
If you are on bare metal you could try these instructions
We need your kubernetes cluster to have a default storage class so that
PersistentVolumeClaim resources in helm charts get resolved to
PersistentVolume resources so that persistent disks can be used.

This is our current recommended quickstart for on premise kubernetes:
- if the above button does not work then please Login to GitHub first and then retry the button
git clonethe new repository via HTTPS and
cdinto the git clone directory
find out what your ingress domain is for your cluster then modify the
jx-requirements.ymlfile and modify the
cluster: ... ingress: domain: mydomain.com ...
verify your cluster does not already have an nginx installation. If it does then please remove the
nginxline from your
helmfile.yamlfile and remove the
helmfiles/nginxfiles. If you are using a custom nginx installation then you will need to figure out your domain by hand and won’t be able to let Jenkins X detect the load balancer IP from its included nginx installation.
git add, commit and push your changes:
git add * git commit -a -m "fix: added domain" git push origin main
- ensure you are connected to your cluster so you can run the following kubectl commands
kubectl get ns kubectl get node
Install the git operator from inside a git clone of the git repository you created above.
switch to the
jx ns jx
