I'm using Helm and for nginx-ingress I need to add some annotations.
Inside the chart's values.yaml file, the podAnnotations is empty ({}).
The question I have is: what is the right way to add these annotations?
The annotations are a child of controller which is the root element of the values.yaml
controller:
...
podAnnotations:
...
Now, I get the feeling that I have to copy the whole values.yaml file into my custom-values.yaml in which I added the annotations.
gt; heml install -f ./custom-values.yaml stable/nginx-ingressBut if I copy the whole values file I get the feeling that I can run into trouble if stable/nginx-ingress changes values inside values.yaml over time
You do not have to copy all values as you can use your own and override only the values you need
The values.yaml file is also important to templates. This file contains the default values for a chart. These values may be overridden by users during helm install or helm upgrade
See https://helm.sh/docs/chart_template_guide/
Thus just add the annotations to custom-values.yaml - plus other default values you want to change - and then run
helm install -f ./custom-values.yaml stable/nginx-ingressHere an example of my custom-values.yaml
controller:
service:
annotations:
field.cattle.io/projectId: c-xxxxx:p-xxxxxand the important part of the result:
...
# Source: nginx-ingress/templates/controller-service.yaml
apiVersion: v1
kind: Service
metadata:
annotations:
field.cattle.io/projectId: "c-xxxxx:p-xxxxx"
labels:
app: nginx-ingress
chart: nginx-ingress-1.20.0
component: "controller"
