Custom NGINX template ΒΆ

The NGINX template is located in the file /etc/nginx/template/nginx.tmpl.

Using a Volume it is possible to use a custom template. This includes using a Configmap as source of the template

          - mountPath: /etc/nginx/template
            name: nginx-template-volume
            readOnly: true
        - name: nginx-template-volume
            name: nginx-template
            - key: nginx.tmpl
              path: nginx.tmpl

Please note the template is tied to the Go code. Do not change names in the variable $cfg.
