# Deploy Jenkins in the Kubernetes cluster
## Deploy Jenkins in the Kubernetes cluster
Deploying **Jenkins** on a Kubernetes cluster can be quite beneficial for managing CI/CD pipelines efficiently. Here's a general guide to get you started:
## **Prerequisites**:
* You should have a running Kubernetes cluster.
* **kubectl** should be configured to connect to your cluster.
### Check Kubernetes cluster and nodes
```
kubectl get nodes
```
## Setup Jenkins deployment
### Create the Jenkins directory and navigate the directory
```
mkdir jenkins
cd jenkins
```
### Create a Jenkins deployment YAML file
Create a YAML file called jenkins-deployment.yaml with the following content
```
vi jenkins-deployment.yaml
```
```
apiVersion: apps/v1
kind: Deployment
metadata:
name: jenkins
spec:
replicas: 1
selector:
matchLabels:
app: jenkins
template:
metadata:
labels:
app: jenkins
spec:
containers:
- name: jenkins
image: jenkins/jenkins:lts
ports:
- name: http-port
containerPort: 8080
- name: jnlp-port
containerPort: 50000
volumeMounts:
- name: jenkins-vol
mountPath: /var/jenkins_home
volumes:
- name: jenkins-vol
emptyDir: {}
```
### Create a Jenkins service YAML file
Expose the Jenkins deployment using a **NodePort** service:
```
vi jenkins-service.yaml
```
```
apiVersion: v1
kind: Service
metadata:
name: jenkins
spec:
selector:
app: jenkins
ports:
- name: http-port
port: 8080
targetPort: 8080
nodePort: 30000
type: NodePort
```
### Apply the YAML file to create the Jenkins service:
```
kubectl apply -f jenkins-deployment.yaml
```
```
kubectl apply -f jenkins-service.yaml
```
Check the service's
```
kubectl get all
```
To verify if the Jenkins service is running from your terminal, execute the following command:
### **Access Jenkins:**
Access Jenkins using the external IP and NodePort:
**Navigate to the NeevCloud panel > Server > Select your node > copy Public\_IP**
Check Node Port
**: Nodeport**
Run this path on your terminal using the sudo (root user)
