Scalare i carichi di lavoro stateful in base ai requisiti in evoluzione dei carichi di lavoro containerizzati.
Prima di iniziare
Per eseguire comandi su un
cluster Kubernetes,
assicurati di disporre delle seguenti risorse:
Individua il nome del cluster Kubernetes o chiedi all'amministratore della piattaforma qual è il nome del cluster.
Accedi e genera
il file kubeconfig per il cluster Kubernetes se non ne hai uno.
Utilizza il percorso kubeconfig del cluster Kubernetes per sostituire
KUBERNETES_CLUSTER_KUBECONFIG in queste istruzioni.
Per ottenere le autorizzazioni necessarie per scalare i carichi di lavoro stateful, chiedi all'amministratore IAM dell'organizzazione di concederti il ruolo Amministratore spazio dei nomi (namespace-admin) nello spazio dei nomi del progetto.
Scalare una risorsa StatefulSet
Sfrutta la funzionalità di scalabilità di Kubernetes per scalare in modo appropriato la quantità di pod in esecuzione nella risorsa StatefulSet.
Scalare manualmente i pod di una risorsa StatefulSet
Per scalare manualmente la risorsa StatefulSet, esegui:
