title: Custom Helpers
---
Kubes ships with several built-in helpers. On top of this, you can define your own custom helpers. This allows you to define new methods and customize Kubes further.
## Example
You define custom helpers in the `.kubes/helpers` folder.
.kubes/helpers/my_helpers.rb
```ruby
module MyHelpers
def database_endpoint
case Kubes.env
when "dev"
"dev-db.cbuqdmc3nqvb.us-west-2.rds.amazonaws.com"
when "prod"
"prod-db.cbuqdmc3nqvb.us-west-2.rds.amazonaws.com"
end
end
end
```
The `database_endpoint` will be available to use in the `.kubes/resources` YAML files. IE:
.kubes/helpers/resources/shared/config_map.yaml
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: demo
labels:
app: demo
data:
DATABASE_ENDPOINT: <%= database_endpoint %>
```
{% include helpers/generator.md %}
