Configura le risorse e le repliche dei contenitori
Questa pagina descrive come configurare le risorse e le repliche dei contenitori per i controller in Config Connector.
Configurare l'allocazione delle risorse per un contenitore del controller Config Connector
In Config Connector versione 1.106 e successive, puoi configurare le risorse CPU e memoria (RAM) allocate a un contenitore in un pod del controller Config Connector. Puoi configurare i seguenti controller:
cnrm-webhook-manager
cnrm-controller-manager
cnrm-deletiondefender
cnrm-resource-stats-recorder
cnrm-unmanaged-detector (Config Connector versione 1.108 e successive)
Ad esempio, puoi configurare la richiesta e il limite di memoria del contenitore webhook del controller cnrm-webhook-manager creando e applicando il seguente file YAML di esempio.
Crea un file denominato configure-webhook-manager.yaml e copia al suo interno il seguente codice YAML:
Utilizza kubectl apply
per applicare la configurazione della risorsa contenitore al cluster:
kubectl apply -f configure-webhook-manager.yaml
Verifica la corretta configurazione eseguendo il seguente comando:
kubectl get controllerresource cnrm-webhook-manager -o jsonpath='{.status.healthy}'
Dovrebbe essere visualizzato il campo status.healthy impostato su true.
Verifica che la nuova configurazione della risorsa personalizzata sia stata applicata al contenitorewebhook.
kubectl get deployment cnrm-webhook-manager -n cnrm-system -o jsonpath='{.spec.template.spec.containers[?(@.name=="webhook")].resources}'
La creazione e la ricreazione dei pod potrebbe richiedere alcuni minuti.
Se Config Connector è configurato per funzionare in modalità con spazio dei nomi, devi utilizzare la risorsa personalizzata NamespacedControllerResource per configurare le risorse dei contenitori per il controller cnrm-controller-manager nello spazio dei nomi designato. La configurazione delle risorse dei contenitori per un controller con nome nello spazio dei nomi è abilitata in Config Connector versione 1.108 e successive. Il seguente file YAML
mostra un esempio di configurazione:
apiVersion:customize.core.cnrm.cloud.google.com/v1beta1kind:NamespacedControllerResourcemetadata:name:cnrm-controller-manager# name should not contain the namespace ID suffixnamespace:NAMESPACEspec:containers:-name:managerresources:limits:cpu:200mmemory:512Mirequests:cpu:100mmemory:256Mi
Sostituisci NAMESPACE con il nome dello spazio dei nomi.
Configura le repliche per un pod del controller Config Connector
In Config Connector versione 1.107 e successive, puoi configurare il numero di repliche per un controller Config Connector. Puoi configurare solo il
cnrm-webhook-manager.
Ad esempio, i passaggi riportati di seguito mostrano come configurare il numero di repliche per il controller cnrm-webhook-manager su 3.
Crea un file denominato configure-webhook-manager.yaml e copia al suo interno il seguente
codice YAML:
Utilizza kubectl apply
per applicare la configurazione modificata al cluster:
kubectl apply -f configure-webhook-manager.yaml
Verifica la corretta configurazione eseguendo il seguente comando.
kubectl get controllerresource cnrm-webhook-manager -o jsonpath='{.status.healthy}'
Dovrebbe essere visualizzato il campo status.healthy impostato su true.
Verifica la presenza di tre pod webhook nel cluster.
kubectl get pods -n cnrm-system -l cnrm.cloud.google.com/component=cnrm-webhook-manager
La creazione e la ricreazione dei pod potrebbe richiedere alcuni minuti.
Ripristinare le modifiche alla configurazione nelle risorse e nelle repliche dei contenitori
Utilizza kubectl
delete
per eliminare le risorse personalizzate ControllerResource che hai configurato. Dopo l'eliminazione, l'operatore di Config Connector ricrea i controller con le risorse e le repliche dei contenitori predefinite.

You can configure the following controllers:\n\n- `cnrm-webhook-manager`\n- `cnrm-controller-manager`\n- `cnrm-deletiondefender`\n- `cnrm-resource-stats-recorder`\n- `cnrm-unmanaged-detector` (Config Connector version 1.108 and later)\n\nFor example, you can configure the memory request and limit of the `webhook`\ncontainer of the `cnrm-webhook-manager` controller by creating and applying\nthe following example YAML file.\n\n1. Create a file named `configure-webhook-manager.yaml` and copy the\n following YAML into it:\n\n apiVersion: customize.core.cnrm.cloud.google.com/v1beta1\n kind: ControllerResource\n metadata:\n name: cnrm-webhook-manager\n spec:\n containers:\n - name: webhook\n resources:\n limits:\n memory: 512Mi\n requests:\n memory: 256Mi\n\n2. Use [`kubectl apply`](https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#apply)\n to apply the container resource configuration to your cluster:\n\n ```\n kubectl apply -f configure-webhook-manager.yaml\n ```\n3. Verify the successful configuration by running the following command:\n\n ```\n kubectl get controllerresource cnrm-webhook-manager -o jsonpath='{.status.healthy}'\n ```\n\n It should display `status.healthy` field set to `true`.\n4. Verify that the new custom resource configuration has been applied to the\n `webhook` container.\n\n ```\n kubectl get deployment cnrm-webhook-manager -n cnrm-system -o jsonpath='{.spec.template.spec.containers[?(@.name==\"webhook\")].resources}'\n ```\n\n Creating and recreating the Pods could take a few minutes.\n\n| **Note:** Some containers have a default value set for the container environment variable `GOMEMLIMIT`. If you configure the memory request value for these containers, the Config Connector operator automatically adjusts the `GOMEMLIMIT` value to 85% of the specified memory request.\n\nIf Config Connector is configured to run in\n[namespaced mode](/config-connector/docs/how-to/install-namespaced), you must\nuse the `NamespacedControllerResource` custom resource to configure container\nresources for the `cnrm-controller-manager` controller within your designated\nnamespace. The configuration of container resources for a namespaced controller\nis enabled in Config Connector version 1.108 and later. The following YAML file\nshows an example configuration: \n\n apiVersion: customize.core.cnrm.cloud.google.com/v1beta1\n kind: NamespacedControllerResource\n metadata:\n name: cnrm-controller-manager # name should not contain the namespace ID suffix\n namespace: \u003cvar translate=\"no\"\u003e\u003cspan class=\"devsite-syntax-l devsite-syntax-l-Scalar devsite-syntax-l-Scalar-Plain\"\u003eNAMESPACE\u003c/span\u003e\u003c/var\u003e\n spec:\n containers:\n - name: manager\n resources:\n limits:\n cpu: 200m\n memory: 512Mi\n requests:\n cpu: 100m\n memory: 256Mi\n\nReplace \u003cvar translate=\"no\"\u003eNAMESPACE\u003c/var\u003e with the name of your namespace.\n\nConfigure replicas for a Config Connector controller Pod\n--------------------------------------------------------\n\nIn Config Connector version 1.107 and later, you can configure the number of\nreplicas for a Config Connector controller. You can only configure the\n`cnrm-webhook-manager`.\n\nFor example, the following steps show how to configure the number of replicas\nfor the `cnrm-webhook-manager` controller to `3`.\n\n1. Create a file named `configure-webhook-manager.yaml` and copy the following\n YAML into it:\n\n apiVersion: customize.core.cnrm.cloud.google.com/v1beta1\n kind: ControllerResource\n metadata:\n name: cnrm-webhook-manager\n spec:\n replicas: 3\n containers:\n - name: webhook\n resources:\n limits:\n memory: 512Mi\n requests:\n memory: 256Mi\n\n2. Use [`kubectl apply`](https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#apply)\n to apply the modified configuration to your cluster:\n\n ```\n kubectl apply -f configure-webhook-manager.yaml\n ```\n3. Verify the successful configuration by running the following command.\n\n ```\n kubectl get controllerresource cnrm-webhook-manager -o jsonpath='{.status.healthy}'\n ```\n\n It should display `status.healthy` field set to `true`.\n4. Verify the presence of 3 webhook Pods within your cluster.\n\n ```\n kubectl get pods -n cnrm-system -l cnrm.cloud.google.com/component=cnrm-webhook-manager\n ```\n\n Creating and recreating the Pods could take a few minutes.\n\n| **Note:** Config Connector includes a [`HorizontalPodAutoscaler`](/kubernetes-engine/docs/concepts/horizontalpodautoscaler) that periodically adjusts the appropriate replicas for the `cnrm-webhook-manager` controller. If you manually configure the replicas using the configuration YAML, the Config Connector operator automatically adjusts the `minReplicas` and `maxReplicas` of the `HorizontalPodAutoscaler` to ensure the cluster maintains at least the specified number of replicas in the configuration YAML.\n\nRevert configuration changes in container resources and replicas\n----------------------------------------------------------------\n\nUse [`kubectl\ndelete`](https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#delete)\nto delete the `ControllerResource` custom resources that you configured. After\ndeletion, the Config Connector operator recreates the controllers with the\ndefault container resources and replicas. \n\n```\nkubectl delete -f configure-webhook-manager.yaml\n```"]]
