Fare riferimento a questo argomento per conoscere le varie tecniche di controllo dell'integrità di Supervisore in relazione ai componenti di TKG.
Controllo dello stato dei pod Supervisore
I pod Supervisore eseguono i componenti dell'infrastruttura TKG.
Controllare se tutti i pod in
Supervisore sono in stato In esecuzione.
kubectl get pods -A | grep "Running"
Nota: In alternativa, è possibile utilizzare
grep -v "Running" per restituire i pod che non sono in esecuzione.
Ad esempio:

Se uno qualsiasi dei pod in
Supervisore non è in stato In esecuzione, esaminare tale pod utilizzando il comando seguente.
kubectl describe pod <POD Name> -n <Namespace>
Controllare lo stato delle risorse di Supervisore
Risorse del controller TKG:
kubectl get tkc
Risorse API del cluster (CAPI, CABPK, CAPW, CAPV):
kubectl get cluster-api
Risorse operatore macchina virtuale:
kubectl get virtualmachines,virtualmachineservices,virtualmachinesetresourcepolicies
Risorsa operatore macchina virtuale con ambito cluster e sincronizzata dalla libreria di contenuti:
kubectl get virtualmachineimages
Risorse di storage:
kubectl get persistentvolumeclaims,cnsnodevmattachment,cnsvolumemetadatas
Risorse di rete (specifiche per NSX):
kubectl get service,lb,lbm,vnet,vnetif,nsxerrors,nsxnetworkinterfaces
Recuperare tutte le risorse
Supervisore e scriverle in un file:
kubectl api-resources --namespaced -o name | paste -d',' -s | xargs kubectl get -n <namespace> > resources_in_namespace.txt
Verifica della presenza di distribuzioni di API del cluster
Verificare che siano presenti distribuzioni CAPI, CAPW e CAPV.

L'operatore macchina virtuale crea l'istanza di VirtualNetworkInterface e ne verifica lo stato. Se una macchina virtuale del nodo non ottiene un IP, questa è la prima area da controllare. La creazione della macchina virtuale ha superato questa fase?
L'operatore macchina virtuale è inoltre responsabile della riconciliazione di VirtualMachineService e dell'aggiornamento del relativo stato. Se un'API Kubernetes del cluster TKG non è accessibile tramite il relativo IP esterno, controllare il registro dell'operatore macchina virtuale.
Ad esempio, scegliere uno dei pod operatore macchina virtuale, specificare lo spazio dei nomi e il container di gestione. (Il comando
logs è per un container. All'interno di qualsiasi pod di controller è presente un container di gestione di cui è possibile controllare i registri).
kubectl logs -f vmware-system-vmop-controller-manager-c8499b9df-5h6f9 -n vmware-system-vmop manager
