Template​

A template for creating Kubernetes manifests is available in the repo app-template-libsonnet.

Structure​

It is good practice to have all your application manifests in a common repository. Here is a recommended directory structure for your Jsonnet files. 

team-kubernetes-manifests
├── apps                          # Put all your k8s applications under /apps
│   ├── myApp1                    # 1 folder pr. application
│   │   ├── test                  # 1 folder pr. environment
│   │   │   ├── app.jsonnet
│   │   │   └── params.json
│   │   ├── dev
│   │   │   ├── app.jsonnet
│   │   │   └── params.json
│   │   ├── common.jsonnet
│   │   └── README.md             # In README put the link to source repo
│   ├── myApp2
