Visualizzazione dei log di ripristino

In questa pagina viene descritto come controllare i log del job di ripristino e utilizzare grep per cercare un errore e assicurarsi che il log di ripristino non contenga errori.

Verifica del completamento in corso...

Utilizza il seguente comando per verificare se l'operazione di ripristino è stata completata: 

kubectl get pods -n apigee

L'output è simile al seguente: 

NAME                           READY     STATUS      RESTARTS   AGE
apigee-cassandra-default-0     1/1       Running     0          1h
apigee-cassandra-default-1     1/1       Running     0          1h
apigee-cassandra-default-2     1/1       Running     0          59m
apigee-cassandra-restore-b4lgf 0/1       Completed   0          51m

Visualizzazione dei log di ripristino

Per visualizzare i log di ripristino di un pod Kubernetes, esegui il comando kubectl logs -f <pod_name> -n <namespace>. Ad esempio:

kubectl logs -f apigee-cassandra-restore-b4lgf -n apigee

L'output è simile al seguente:

Convalida in corso del ripristino

Convalida il ripristino testando l'indirizzo IP del tuo traffico in entrata e testandolo con del traffico.

  1. Ottieni EXTERNAL-IP con il seguente comando: 
    kubectl get svc -n istio-system
     
    NAME                       TYPE           CLUSTER-IP     EXTERNAL-IP    PORT(S)                                                                      AGE
istio-ingressgateway       LoadBalancer   10.11.123.45   34.56.78.90   15021:32225/TCP,80:32208/TCP,443:31942/TCP,15012:32689/TCP,15443:31936/TCP   1d

  2. Dalla riga di comando, recupera o aggiorna le credenziali di autenticazione gcloud, come illustrato nell'esempio seguente: 

    TOKEN=$(gcloud auth print-access-token)
  3. Testa l'ingress tramite un apiproxy esistente nel tuo ambiente Apigee insieme alla chiave API o al token di accesso: 
    Curl -v https://EXTERNAL-IP/basepath -H 'envgroup hostalias'

    Ad esempio: 

    curl -v 'https://example.com/oauth/client_credential' \
  --resolve edgehybrid-staging-func-runtime-wf.hybrid.e2e.apigeeks.net:443:34.56.78.90 \
  -H 'Authorization: Bearer ${TOKEN}'

Configurazione DNS per il nuovo cluster e la migrazione del traffico

Quando la convalida ti soddisfa, reindirizza il traffico al nuovo cluster e modifica la voce DNS in un nuovo indirizzo EXTERNAL-IP in entrata.
