Sintomi

La procedura di verifica del certificato TLS nei pod Cassandra potrebbe non riuscire con un errore simile al seguente:

Possibili cause

Causa Descrizione Istruzioni per la risoluzione dei problemi applicabili a
Il certificato CA Apigee non corrisponde nei cluster Apigee Se il certificato CA Apigee non corrisponde tra i cluster, la verifica del certificato TLS in Cassandra potrebbe non riuscire. Apigee hybrid

Prerequisiti

  • kubectl deve essere installato e configurato per accedere ai cluster Apigee.
  • jq è necessario per formattare i contenuti JSON.
  • keytool è necessario per stampare i certificati TLS.
  • cmctl è necessario per riemettere i certificati utilizzando Cert Manager.

Causa: il certificato CA di Apigee non corrisponde tra i cluster Apigee

Diagnosi

  1. Leggi il secret apigee-ca e stampa il certificato CA Apigee di tutti i cluster utilizzando il seguente comando: 
    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d | keytool -printcert | grep Version -B 10

    Un esempio di output:

    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d | keytool -printcert | grep Version -B 10

  2. Leggi il segreto apigee-cassandra-default-tls e verifica se il certificato CA Apigee riportato sopra è stato utilizzato durante la generazione del certificato Cassandra. Il segreto apigee-cassandra-default-tls contiene il certificato CA Apigee in ca.crt: 
    kubectl -n apigee get secret apigee-cassandra-default-tls -o json | jq -r '.data["ca.crt"]' | base64 -d | keytool -printcert | grep Version -B 10

    Un esempio di output:

    kubectl -n apigee get secret apigee-cassandra-default-tls -o json | jq -r '.data["ca.crt"]' | base64 -d | keytool -printcert | grep Version -B 10

  3. Nell'esempio riportato sopra, il numero di serie del certificato CA Apigee trovato nel segreto apigee-ca corrisponde al certificato CA Apigee trovato nel segreto apigee-cassandra-default-tls: afcc2ef957cebfd52b118b0b1622021. Ciò conferma che il certificato Cassandra è stato firmato dallo stesso certificato CA Apigee. Possiamo verificare ulteriormente la situazione seguendo i passaggi riportati di seguito.
  4. Estrai il file PEM del certificato CA Apigee: 
    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d > apigee-ca.crt

    Un esempio di output:

    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d > apigee-ca.crt
cat apigee-ca.crt

  6. Verifica il certificato Cassandra utilizzando il certificato CA Apigee: 
    openssl verify -CAfile apigee-ca.crt apigee-cassandra-default-tls.crt

    Un output di esempio riuscito:

    openssl verify -CAfile apigee-ca.crt apigee-cassandra-default-tls.crt
apigee-cassandra-default-tls.crt: OK

    Un esempio di output di errore:

    openssl verify -CAfile apigee-ca.crt apigee-cassandra-default-tls.crt
CN = apigee-cassandra-default.apigee.svc.cluster.local
error 20 at 0 depth lookup: unable to get local issuer certificate
error apigee-cassandra-default-tls.crt: verification failed

Risoluzione

  1. Seleziona un cluster Apigee con il certificato CA Apigee corretto.
  2. Esporta il secret del certificato CA Apigee dal cluster in un file: 
    kubectl -n cert-manager get secret apigee-ca -o yaml > apigee-ca.yaml
  3. Applica il segreto del certificato CA Apigee a tutti gli altri cluster selezionando un cluster alla volta, poi esegui tutti i passaggi rimanenti in tutti i cluster: 
    kubectl -n cert-manager apply -f apigee-ca.yaml
  4. Esporta tutti i certificati esistenti disponibili nello spazio dei nomi apigee in un file di backup: 
    kubectl -n apigee get certificates --all -o yaml > all-certificates.yaml
  5. Esegui il seguente comando cmctl per riemettere tutti i certificati trovati nello spazio dei nomi apigee: 
    cmctl renew --namespace=apigee --all

    Un esempio di output:

    cmctl renew --namespace=apigee --all

  Manually triggered issuance of Certificate apigee/apigee-udca-demo-hybrid-de-5fdc6d2
  Manually triggered issuance of Certificate apigee/apigee-watcher-demo-hybrid-de-5fdc6d2

    Questo passaggio dovrebbe emettere nuovamente tutti i certificati di runtime Apigee utilizzando il certificato CA Apigee appena importato e dovrebbe risolvere il problema.

  6. Controlla la data di emissione di tutti i certificati rispetto all'ora UTC e verifica se sono stati emessi di nuovo: 
    kubectl get certificates -n apigee -o json | jq -r '.items[] | "\(.metadata.name): \(.status.notBefore)"'
date -u

    Un esempio di output:

    kubectl get certificates -n apigee -o json | jq -r '.items[] | "\(.metadata.name): \(.status.notBefore)"'
