How to integrate Jenkins deploy to Kubernetes ?
I have a plugin Kubernetes Continuous Deploy.
But I have a error. ERROR: ERROR: java.lang.IllegalStateException: Kubernetes config files are not specified.
I don't know what need to past on Kubeconfig file ?

I installed Jenkins on my -AWS EC2 Ubuntu- and on the same server I'm running Docker. what I'm trying to do is to build a pipeline via Jenkins on that EC2 Instance. my jenkinsfile stored on Github
When I run the pipeline I get the following error:
Jenkins’ doesn’t have label ‘docker'
How to solve this problem?
I went to manage Jenkins -> global tools and also to configure system
but non of these solve the problem.
Any suggestions?
I have my on premise kubernetes cluster.
I want to setup CD with jenkins.
I have tried two plugins which are available for kubernetes deployment.
Kubernetes Continuous Deploy Plugin
Kubernetes plugin
The question here is, jenkins master will require the .kube/config
file to connect to the kubernetes cluster for doing deployments.
Is this the best practice to copy the .kube/config file of your kubernetes master to jenkins master to provide full acesss of your kubernetes cluster for deployment purpose.
Please do let me know if you have any other suggestions for my ON-PREM kubernetes cluster CD.
you have two options
1. put all kubeconfig files in a separate git repo, say, kubeVault .git, and name the files using cluster name. Accept cluster as build paramter in jenkins. Lookup the respective kubeconfig from kubeVault repo and use it as target platform and deploy the container. We have used this approach in one of the project. you need to build some logic in the pipeline groovy code
define build parameters and set them using the fields from kubeconfig file. post build generate actual kubeconfig file from build params and keep it in /tmp directory. pass the kubeconfig location to kubectl to deploy the k8s obejects/pod
I am trying to create a Jenkins pipeline on Openshift, that automatically runs a Jenkins service when we start the pipeline build. I referred few templates online and created a Jenkins pod and a pipeline. But whenever I try to run the pipeline, It shows build status as "not started.
Later, I created a standalone Jenkins service in Openshift, created a Jenkins file in open shift and tried executing it. I encountered authentication issues while connecting with Openshift from Jenkins.
Can anyone guide me, if I am missing something or any other working templates for a pipeline?
Thanks
It’s because of permissions
Jenkins runs with Jenkins user and openshift doesn’t know how to connect to it
Create a new service account in openshift jenkins
I am trying to create a jenkins job that will build a github project inside a docker container that shall be generated from the Dockerfile contained in the github project itself. To do so, I am using docker slaves plugin but I am running into an issue when I run the jenkins job.
Error during container provisioning
The configuration I am using for the jenkins job is the following:
jenkins job config
So the job right now should only clone the repo and build the image. Any suggestions?
The solution to the problem was to set the remoting image to jenkinsci/slave in the global configuration of jenkins
Jenkins global config
As part of a Jenkins pipeline to build and deploy an app to Google's Kubernetes service (GKE), I've created a script to carry out the following deployment to GKE:
checkout code
setup authentication to gcloud and
create the deployment and service using kubectl:
Detailed steps implemented by the script are as follows:
a) Create the docker registry authentication file (.json)
b) login to the google docker registry using the authentication file
c) initialise a git repo in the current directory
d) add the remote origin in prep for code pull
e) pull the source code for the microservice container
f) Create a kubectl configurtion file and directory to authenticate to the kubernetes cluster in Gcloud
g) Create a keyfile for a Gcloud service account that needs to authenticate to the container service
h) Activate the service account
i) Get the credentials for the container cluster from Gcloud
j) Run kubectl apply to create the kubernetes services
Full, tested, script at: https://pastebin.com/sZPrQuzD
If I put this sequence of steps in a scripts on an AWS EC2 instance and run it manually it works. However,the Jenkins build step fails at the the point kubectl is invoked to run the service, with the following error:
gcloud container clusters get-credentials jenkins-cd --zone europe-west1-b --project noon-prod
Fetching cluster endpoint and auth data.
ERROR: (gcloud.container.clusters.get-credentials) ResponseError: code=403, message=Request had insufficient authentication scopes.
Build step 'Execute shell' marked build as failure
The full error dump from the Jenkins run is as follows:
https://pastebin.com/pSWPQ5Ei
My questions:
a) How to fix this? Surely it can't be that difficult to get authentication running from Jenkins?
b) Is this the correct way to authenticate to the gcloud container service from a Jenkins system which is not on Gcloud infrastructure at all?
Many thanks in advance for any help!

We're working on an open source project called Jenkins X which is a proposed sub project of the Jenkins foundation aimed at automating CI/CD on Kubernetes using Jenkins and GitOps for promotion.
We worked around some of the issues you've been having by running the Jenkins pipelines inside the kubernetes cluster; so there's no need to authenticate with GKE.
When you merge a change to the master branch, Jenkins X creates a new semantically versioned distribution of your app (pom.xml, jar, docker image, helm chart). The pipeline then automates the generation of Pull Requests to promote your application through all of the Environments via GitOps.
Here's a demo of how to automate CI/CD with multiple environments on Kubernetes using GitOps for promotion between environments and Preview Environments on Pull Requests - using Spring Boot and nodejs apps (but we support many languages + frameworks).
