- CloudBees AWS Credentials
- Kubernetes Credentials
- Kubernetes Continuous Deploy

Create Credentials

- docker credentials
         (credentialsId: 'docker_credentials',  username: 'username', password: 'password')
- kubernetes config credentials
         (credentialsId: 'kube_config', variable: 'KUBECONFIG')
- aws configure credentials
         (accessKeyVariable: 'AWS_ACCESS_KEY_ID', credentialsId: 'aws_configure', secretKeyVariable: 'AWS_SECRET_ACCESS_KEY')

And one more step we need to do in Github

Add JenkinsFile Content inside pipeline section

Now we can try by change anything inside Github
