5.5.2.4. Enabling proxy support

Procedure

1. Edit the watches.yaml file to include overrides based on an environment variable by adding the overrideValues field:

   ...
   - group: demo.example.com
     version: v1alpha1
     kind: Nginx
     chart: helm-charts/nginx
     overrideValues:
       proxy.http: $HTTP_PROXY
   ...

2. Add the proxy.http value in the helm-charts/nginx/values.yaml file:

   ...
   proxy:
     http: ""
     https: ""
     no_proxy: ""

3. To make sure the chart template supports using the variables, edit the chart template in the helm-charts/nginx/templates/deployment.yaml file to contain the following:

   containers:
     - name: {{ .Chart.Name }}
       securityContext:
         - toYaml {{ .Values.securityContext | nindent 12 }}
       image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}"
       imagePullPolicy: {{ .Values.image.pullPolicy }}
       env:
         - name: http_proxy
           value: "{{ .Values.proxy.http }}"

4. Set the environment variable on the Operator deployment by adding the following to the config/manager/manager.yaml file:

   containers:
    - args:
      - --leader-elect
      - --leader-election-id=ansible-proxy-demo
      image: controller:latest
      name: manager
      env:
        - name: "HTTP_PROXY"
          value: "http_proxy_test"
