In diesem Thema wird erläutert, wie Sie einen benutzerdefinierten Kubernetes-Namespace für cert-manager angeben.
In den meisten Fällen wird cert-manager im Namespace cert-manager ausgeführt. Bei einigen Nutzern können Unternehmensrichtlinien die Erstellung neuer Kubernetes-Namespaces einschränken oder es kann erforderlich sein, dass cert-manager in einem anderen Namespace ausgeführt wird, zum Beispiel kube-system.
Benutzerdefinierten Namespace für cert-manager angeben
Wenden Sie die Namespace-Änderung mit apigeectl init an:
apigeectl init -f path-to-overrides.yaml
Prüfen Sie mit dem Befehl kubectl get pods, ob cert-manager im neuen Namespace korrekt installiert wurde:
kubectl get pods -n new-cert-manager-namespace
NAME READY STATUS RESTARTS AGE
cert-manager-1234567-abcde 1/1 Running 0 21s
cert-manager-cainjector-23456789a-bcdef 1/1 Running 0 22s
cert-manager-webhook-3456789ab-cdef0 1/1 Running 0 20s
Wenn cert-manager bereits ausgeführt wurde, löschen Sie die cert-manager-Instanz im cert-manager-Namespace. Folgen Sie dazu der Anleitung unter Dokumentation zur Deinstallation im Cert-Manager.

For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\nThis topic explains how to specify a custom Kubernetes namespace for\n[cert-manager](https://cert-manager.io/).\n\nIn most cases, cert-manager runs in the `cert-manager` namespace. Some users may have\ncompany policies restricting the creation of new Kubernetes namespaces or have policies requiring\ncert-manager to be run in a different namespace, for example `kube-system`.\n\n\nSpecify a custom namespace for cert-manager\n-------------------------------------------\n\n1. Create the namespace if needed: \n\n ```\n kubectl create namespace new-cert-manager-namespace\n ```\n2. Install cert-manager following the instructions in [Installation:\n Introduction](https://cert-manager.io/v1.10-docs/installation/) in the cert-manager documentation. **Note:** You will have to edit the installation manifests to install cert-manager in a custom namespace.\n3. Add a [`certManager`](/apigee/docs/hybrid/v1.10/config-prop-ref#certmanager) stanza to your overrides file. \n\n ```\n certManager:\n namespace: new-cert-manager-namespace\n \n ```\n4. Apply the namespace change with `apigeectl init`: \n\n ```\n apigeectl init -f path-to-overrides.yaml\n ```\n5. Verify that cert-manager installed correctly in the new namespace with the `kubectl get pods` command: \n\n ```\n kubectl get pods -n new-cert-manager-namespace\n ``` \n\n ```\n NAME READY STATUS RESTARTS AGE\n cert-manager-1234567-abcde 1/1 Running 0 21s\n cert-manager-cainjector-23456789a-bcdef 1/1 Running 0 22s\n cert-manager-webhook-3456789ab-cdef0 1/1 Running 0 20s\n ```\n6. If cert manager had previoiusly been running, delete the `cert-manager` instance in the `cert-manager` namespace by following the instructions in [Uninstall\n in the cert-manager documentation](https://cert-manager.io/docs/installation/kubectl/#uninstalling)."]]
