# Configuring the cluster-wide proxy on the External DNS Operator {#external-dns-operator-cluster-wide-proxy}

To propagate proxy settings to your deployed Operators, configure the cluster-wide proxy. The Operator Lifecycle Manager (OLM) automatically updates these Operators with the new `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY` environment variables.

## Trusting the certificate authority of the cluster-wide proxy {#nw-configuring-cluster-wide-proxy_external-dns-operator-cluster-wide-proxy}

You can configure the External DNS Operator to trust the certificate authority of the cluster-wide proxy.

**Procedure**

1. Create the config map to contain the CA bundle in the `external-dns-operator` namespace by running the following command:

   ```terminal
   $ oc -n external-dns-operator create configmap trusted-ca
   ```
2. To inject the trusted CA bundle into the config map, add the `config.openshift.io/inject-trusted-cabundle=true` label to the config map by running the following command:

   ```terminal
   $ oc -n external-dns-operator label cm trusted-ca config.openshift.io/inject-trusted-cabundle=true
   ```
3. Update the subscription of the External DNS Operator by running the following command:

   ```terminal
   $ oc -n external-dns-operator patch subscription external-dns-operator --type='json' -p='[{"op": "add", "path": "/spec/config", "value":{"env":[{"name":"TRUSTED_CA_CONFIGMAP_NAME","value":"trusted-ca"}]}}]'
   ```

**Verification**

- After deploying the External DNS Operator, verify that the trusted CA environment variable is added by running the following command. The output must show `trusted-ca` for the `external-dns-operator` deployment.

  ```terminal
  $ oc -n external-dns-operator exec deploy/external-dns-operator -c external-dns-operator -- printenv TRUSTED_CA_CONFIGMAP_NAME
  ```
