Testing

Ran tests to print out the helm chart for 3 different passed in values using the command:

helm template litellm-helm deploy/charts/litellm-helm -n litellm --values ~/scratchpad/litellm.yaml | yq 'select(.kind == "Deployment") | .metadata'

Where ~/scratchpad/litellm.yaml is a local helm values file and I filter the output to the Deployment metadata.

1. Deployment annotations defined

   deploymentAnnotations:
     "reloader.stakater.com/auto": "true"
     something: else

   ➜ helm template litellm-helm deploy/charts/litellm-helm -n litellm --values ~/scratchpad/litellm.yaml | yq 'select(.kind == "Deployment") | .metadata'
   annotations:
     reloader.stakater.com/auto: "true"
     something: else
   name: litellm-helm
   labels:
     helm.sh/chart: litellm-helm-0.4.4
     app.kubernetes.io/name: litellm
     app.kubernetes.io/instance: litellm-helm
     app.kubernetes.io/version: "v1.50.2"
     app.kubernetes.io/managed-by: Helm

2. Deployment annotations defined as empty dict

   deploymentAnnotations: {}

   ➜ helm template litellm-helm deploy/charts/litellm-helm -n litellm --values ~/scratchpad/litellm.yaml | yq 'select(.kind == "Deployment") | .metadata'
   annotations: {}
   name: litellm-helm
   labels:
     helm.sh/chart: litellm-helm-0.4.4
     app.kubernetes.io/name: litellm
     app.kubernetes.io/instance: litellm-helm
     app.kubernetes.io/version: "v1.50.2"
     app.kubernetes.io/managed-by: Helm

3. Deployment annotations not defined

   ➜ helm template litellm-helm deploy/charts/litellm-helm -n litellm --values ~/scratchpad/litellm.yaml | yq 'select(.kind == "Deployment") | .metadata'
   annotations: {}
   name: litellm-helm
   labels:
     helm.sh/chart: litellm-helm-0.4.4
     app.kubernetes.io/name: litellm
     app.kubernetes.io/instance: litellm-helm
     app.kubernetes.io/version: "v1.50.2"
     app.kubernetes.io/managed-by: Helm
