title: Kubes YAML
---

You can write your Kubernetes resources in YAML format.

    .kubes
    └── resources
        └── web
            ├── deployment.yaml
            └── service.yaml

## YAML and Templating

Kubes provides a little extra power for the YAML format. The YAML files are processed through an ERB templating language.  So you have dynamic control. Here's an example with `Kubes.env` and the `built_image` helper.

.kubes/resources/web/deployment.yaml

```yaml
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: demo-web
  labels:
    app: demo
  namespace: default
spec:
  replicas: <%= Kubes.env == "prod" ? 2 : 1 %>
  selector:
    matchLabels:
      app: demo
  template:
    metadata:
      labels:
        app: demo
    spec:
      containers:
      - name: demo-web
        image: <%= built_image %>
```
