Create first pipeline

DevSecOps
#1

I am on the Section 2-10:Pipeline.
I have configure jenkins, minikube, docker on my windows 11 using WSL2.
However while trying the first pipeline which find the versions of docker, maven and kubernetes,
even after configuring the authenticaion for kubernetes, i receive the following error:

  • docker -v
    Docker version 24.0.7, build afdd53b
    [Pipeline] }
    [Pipeline] // stage
    [Pipeline] stage
    [Pipeline] { (kubernetes version)
    [Pipeline] withKubeConfig
    [Pipeline] {
    [Pipeline] sh
  • kubectl version
    error: error loading config file “/var/lib/jenkins/workspace/Verions/.kube17806414685342613723config”: illegal base64 data at input byte 64
    [Pipeline] }
    [kubernetes-cli] kubectl configuration cleaned up
    [Pipeline] // withKubeConfig
    [Pipeline] }
    [Pipeline] // stage
    [Pipeline] }
    [Pipeline] // node
    [Pipeline] End of Pipeline
    ERROR: script returned exit code 1

Hi al1,
I have follow the lecture to copy the content of /.kube/config.
However, the difference is mine refer to other file for the ca-cert, client-key and client-cert,
if i continue to use them, my error is permission to open these 3 files denied.
so i copy and paste them in the config just like the one in lecture, and got this error,
this file .kube17806414685342613723config is not there in /var/lib/jenkins/workspace/Verions/

here is the kubeconfig file:

Hi there, i have solved the issue with coding base64 of the data before copy and paste. Thanks.

#6

@kel_line How to do encoding with base 64?

#7

use this command: cat /home/…/client.crt | base64 -w 0 ; echo
replace the path with yours, what file to decode can be found from the /.kube/config
