Using Jenkins Template Folder:

Jenkins template folder is there to help you get started with Declarative Jenkins pipeline with a kubernetes agent. To use the template folder, follow the following steps:

1. Copy jenkins-template folder to your repository and rename it to a more appropriate name, maybe jenkins.
2. Open up Jenkinsfile and change label-name (on line 4) to an appropraite label-name that would suit your project.
3. Navigate to agent.yaml file and change container-name (on line 8) to an appropriate value, you would be using this value under your steps to let Jenkins know on which container you would like to carry out your commands in.
4. While on agent.yaml file, change image-name (on line 9) to an image you would like to use for the particular container.
5. If you would like to alter resources block, feel free to do so, just make sure you do not allocate more resources than a node can sustain.
