Chapter 6. Running the RHDH application behind a corporate proxy

Procedure

1. Set the proxy information in your Helm configuration file:

   upstream:
     backstage:
       extraEnvVars:
         - name: HTTP_PROXY
           value: '<http_proxy_url>'
         - name: HTTPS_PROXY
           value: '<https_proxy_url>'
         - name: NO_PROXY
           value: '<no_proxy_settings>'

   Where,

   <http_proxy_url>

   Denotes a variable that you must replace with the HTTP proxy URL.

   <https_proxy_url>

   Denotes a variable that you must replace with the HTTPS proxy URL.

   <no_proxy_settings>

   Denotes a variable that you must replace with comma-separated URLs, which you want to exclude from proxying, for example, foo.com,baz.com.

   Example: Setting proxy variables using Helm Chart

   upstream:
     backstage:
       extraEnvVars:
         - name: HTTP_PROXY
           value: 'http://10.10.10.105:3128'
         - name: HTTPS_PROXY
           value: 'http://10.10.10.106:3128'
         - name: NO_PROXY
           value: 'localhost,example.org'

2. Save the configuration changes.

Procedure

1. Perform one of the following steps based on your role:

   • As an administrator, set the proxy information in the Operator’s default ConfigMap file:

     1. Search for a ConfigMap file named backstage-default-config in the default namespace rhdh-operator and open it.
     2. Find the deployment.yaml key.

     3. Set the value of the HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables in the Deployment spec as shown in the following example:

        Example: Setting proxy variables in a ConfigMap file

        # Other fields omitted
          deployment.yaml: |-
            apiVersion: apps/v1
            kind: Deployment
            spec:
              template:
                spec:
                  # Other fields omitted
                  initContainers:
                    - name: install-dynamic-plugins
                      # command omitted
                      env:
                        - name: NPM_CONFIG_USERCONFIG
                          value: /opt/app-root/src/.npmrc.dynamic-plugins
                        - name: HTTP_PROXY
                          value: 'http://10.10.10.105:3128'
                        - name: HTTPS_PROXY
                          value: 'http://10.10.10.106:3128'
                        - name: NO_PROXY
                          value: 'localhost,example.org'
                      # Other fields omitted
                  containers:
                    - name: backstage-backend
                      # Other fields omitted
                      env:
                        - name: APP_CONFIG_backend_listen_port
                          value: "7007"
                        - name: HTTP_PROXY
                          value: 'http://10.10.10.105:3128'
                        - name: HTTPS_PROXY
                          value: 'http://10.10.10.106:3128'
                        - name: NO_PROXY
                          value: 'localhost,example.org'

   • As a developer, set the proxy information in your custom resource (CR) file as shown in the following example:

     Example: Setting proxy variables in a CR file

     spec:
       # Other fields omitted
       application:
         extraEnvs:
           envs:
             - name: HTTP_PROXY
               value: 'http://10.10.10.105:3128'
             - name: HTTPS_PROXY
               value: 'http://10.10.10.106:3128'
             - name: NO_PROXY
               value: 'localhost,example.org'
