Gestionar HPAs con kubectl

Esta sección describe la gestión de HPA con kubectl. Este documento tiene instrucciones sobre cómo:

  • Crear un HPA

  • Obtener información sobre HPAs

  • Suprimir un HPA

  • Configurar tus HPAs para escalar con la utilización de CPU o memoria

  • Configurar tus HPAs para escalar utilizando métricas personalizadas, si usas una herramienta de terceros como Prometheus para métricas

Puedes crear, ver y eliminar HPAs desde la GUI de Rancher. También puedes configurarlos para escalar en función del uso de CPU o memoria desde la GUI de Rancher. Para más información, consulta Gestionar HPAs con la GUI de Rancher. Para escalar HPAs basados en otras métricas que no sean CPU o memoria, aún necesitas kubectl.

Comando básico de kubectl para gestionar HPAs

Si tienes un archivo de manifiesto de HPA, puedes crear, gestionar y suprimir HPAs utilizando kubectl:

  • Creando HPA

    • Con manifiesto: kubectl create -f <HPA_MANIFEST>

    • Sin manifiesto (Solo soporte para CPU): kubectl autoscale deployment hello-world --min=2 --max=5 --cpu-percent=50

  • Obteniendo información de HPA

    • Básica: kubectl get hpa hello-world

    • Descripción detallada: kubectl describe hpa hello-world

  • Eliminando HPA

    • kubectl delete hpa hello-world

Ejemplo de definición de manifiesto HPA

El manifiesto HPA es el archivo de configuración utilizado para gestionar un HPA con kubectl.

El siguiente fragmento demuestra el uso de diferentes directivas en un manifiesto HPA. Consulta la lista debajo del ejemplo para entender el propósito de cada directiva.

apiVersion: autoscaling/v2beta1
kind: HorizontalPodAutoscaler
metadata:
  name: hello-world
spec:
  scaleTargetRef:
    apiVersion: extensions/v1beta1
    kind: Deployment
    name: hello-world
  minReplicas: 1
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      targetAverageUtilization: 50
  - type: Resource
    resource:
      name: memory
      targetAverageValue: 100Mi
Directiva Descripción

apiVersion: autoscaling/v2beta1

La versión del grupo de API de Kubernetes autoscaling en uso. Este manifiesto de ejemplo utiliza la versión beta, por lo que el escalado por CPU y memoria está habilitado.

name: hello-world

Indica que HPA está realizando escalado automático para el despliegue hello-word.

minReplicas: 1

Indica que el número mínimo de réplicas en ejecución no puede bajar de 1.

maxReplicas: 10

Indica que el número máximo de réplicas en el despliegue no puede superar 10.

targetAverageUtilization: 50

Indica que el despliegue escalará los pods cuando el promedio de los pods en ejecución utilice más del 50% de su CPU solicitada.

targetAverageValue: 100Mi

Indica que el despliegue escalará los pods cuando el promedio de los pods en ejecución utilice más de 100Mi de memoria.

Configurando HPA para escalar utilizando métricas de recursos (CPU y memoria)

Los clústeres creados en Rancher v2.0.7 y superiores tienen todos los requisitos necesarios (metrics-server y configuración del clúster de Kubernetes) para utilizar el Horizontal Pod Autoscaler.

Ejecuta los siguientes comandos para comprobar si las métricas están disponibles en tu instalación:

$ kubectl top nodes
NAME                              CPU(cores)   CPU%      MEMORY(bytes)   MEMORY%

Configurando HPA para escalar utilizando métricas personalizadas con Prometheus

Puedes configurar HPA para escalar automáticamente en función de métricas personalizadas proporcionadas por software de terceros. El caso de uso más común para el escalado automático utilizando software de terceros se basa en métricas a nivel de aplicación (es decir, solicitudes HTTP por segundo). HPA utiliza la custom.metrics.k8s.io API para consumir estas métricas. Esta API se habilita desplegando un adaptador de métricas personalizado para la solución de recolección de métricas.

Para este ejemplo, vamos a utilizar Prometheus. Comenzamos con las siguientes suposiciones:

  • Prometheus está desplegado en el clúster.

  • Prometheus está configurado correctamente y recolectando métricas adecuadas de pods, nodos, namespaces, etc.

  • Prometheus está expuesto en la siguiente URL y puerto: http://prometheus.mycompany.io:80

Prometheus está disponible para su despliegue en el catálogo de Rancher v2.0. Despliega desde el catálogo de Rancher si no está ya en funcionamiento en tu clúster.

Para que HPA utilice métricas personalizadas de Prometheus, se requiere el paquete k8s-prometheus-adapter en el espacio de nombres kube-system de tu clúster. Para instalar k8s-prometheus-adapter, estamos utilizando el gráfico de Helm disponible en banzai-charts.

  1. Inicializa Helm en tu clúster.

      # kubectl -n kube-system create serviceaccount tiller
  kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
  helm init --service-account tiller

  2. Clona el repositorio banzai-charts de GitHub:

      # git clone https://github.com/banzaicloud/banzai-charts

  3. Instala el gráfico prometheus-adapter, especificando la URL y el número de puerto de Prometheus.

      # helm install --name prometheus-adapter banzai-charts/prometheus-adapter --set prometheus.url="http://prometheus.mycompany.io",prometheus.port="80" --namespace kube-system

  4. Verifica que prometheus-adapter esté funcionando correctamente. Revisa el pod del servicio y los logs en el espacio de nombres kube-system.

  5. Verifica que el pod del servicio esté Running. Introduce el siguiente comando. ` # kubectl get pods -n kube-system ` En la salida resultante, busca un estado de Running. + NOMBRE LISTO ESTADO REINICIOS EDAD …​ prometheus-adapter-prometheus-adapter-568674d97f-hbzfx 1/1 En ejecución 0 7h …​ +

  6. Revisa los logs del servicio para asegurarte de que el servicio esté funcionando correctamente introduciendo el comando que sigue. ` # kubectl logs prometheus-adapter-prometheus-adapter-568674d97f-hbzfx -n kube-system ` Luego revisa la salida del log para confirmar que el servicio está en funcionamiento.

  7. Verifica que la API de métricas sea accesible desde kubectl.

    • Si accedes al clúster directamente, introduce la URL de tu servidor en la configuración de kubectl en el siguiente formato: https://<Kubernetes_URL>:6443.

      # kubectl get --raw /apis/custom.metrics.k8s.io/v1beta1

      Si la API es accesible, deberíais recibir una salida similar a la que sigue.
