how to deploy project with jenkins pipeline script on kubernetes1.19

1. install pipeline plugin, git parameter plugin

2. get credentialsId from manage credentials

3. add docker repository in maven settings.xml

   <server>
       <id>docker-repo</id>
       <username>user</username>
       <password>password</password>
       <configuration>
           <email>eamil</email>
       </configuration>
   </server>
   

4. create image pull secret in kubernetes, add imagePullSecrets in k8s yaml

   kubectl create secret docker-registry chenshi --docker-username=user --docker-password=password --docker-email=email
   

   spec:
     containers:
     - name: nginx
     imagePullSecrets:
     - name: myregistrykey
   

5. pipeline script

   pipeline {
   
       agent any
   
       stages {
           stage('checkout') {
               steps {
                   dir('/projects/project1/') {
                       git branch: "${branch}",
                       credentialsId: 'from manage credentials',
                       url: 'https://chenshi.net/projects/project1/'
                   }
               }
           }
           stage('build') {
               steps {
                   dir('/projects/project1/') {
                       sh'''
                       mvn clean package -Ddocker-image.tag=${dockerTag} -DpushImage
                       #rm -rf /projects/project1/dist/ && yarn && yarn build && docker build -t chenshi.net/project:${tag} . && docker push chenshi.net/project:${tag}
                       '''
                   }
               }
           }
           stage('deploy') {
               steps {
                   sh '''
                   /scrips/project1.sh ${tag}
                   '''
                   }
               }
           }
