Falha na validação do certificado TLS do Cassandra

Está a ver a documentação do Apigee e do Apigee Hybrid.
Ver documentação do Apigee Edge.

Sintomas

O processo de validação do certificado TLS nos pods do Cassandra pode falhar com um erro semelhante ao seguinte:

Causas possíveis

Causa Descrição Instruções de resolução de problemas aplicáveis a
O certificado da CA do Apigee não corresponde nos clusters do Apigee Se o certificado da AC do Apigee não corresponder entre clusters, a validação do certificado TLS no Cassandra pode falhar. Apigee Hybrid

Pré-requisitos

  • Okubectl tem de estar instalado e configurado para aceder aos clusters do Apigee.
  • Ojq é necessário para formatar conteúdo JSON.
  • Okeytool é necessário para imprimir certificados TLS.
  • Ocmctl é necessário para reemitir certificados através do Cert Manager.

Causa: o certificado da AC do Apigee não corresponde nos clusters do Apigee

Diagnóstico

  1. Leia o segredo apigee-ca e imprima o certificado da AC do Apigee de todos os clusters com o seguinte comando: 
    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d | keytool -printcert | grep Version -B 10

    Exemplo de resultado:

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

  2. Leia o segredo do apigee-cassandra-default-tls e verifique se o certificado de AC do Apigee acima foi usado ao gerar o certificado do Cassandra. O segredo apigee-cassandra-default-tls contém o certificado da AC do Apigee em 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

    Exemplo de resultado:

    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. No exemplo acima, o número de série do certificado da AC do Apigee encontrado no segredo apigee-ca corresponde ao certificado da AC do Apigee encontrado no segredo apigee-cassandra-default-tls: afcc2ef957cebfd52b118b0b1622021. Isto confirma que o certificado do Cassandra foi assinado pelo mesmo certificado da CA do Apigee. Podemos validar esta situação mais detalhadamente seguindo os passos abaixo.
  4. Extraia o ficheiro PEM do certificado da AC do Apigee: 
    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d > apigee-ca.crt

    Exemplo de resultado:

    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. Valide o certificado do Cassandra com o certificado da AC do Apigee: 
    openssl verify -CAfile apigee-ca.crt apigee-cassandra-default-tls.crt

    Um exemplo de resultado com êxito:

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

    Um exemplo de saída de falha:

    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

Resolução

  1. Selecione um cluster do Apigee que tenha o certificado de CA do Apigee correto.
  2. Exporte o segredo do certificado da AC do Apigee desse cluster para um ficheiro: 
    kubectl -n cert-manager get secret apigee-ca -o yaml > apigee-ca.yaml
  3. Aplique o segredo do certificado da AC do Apigee acima a todos os outros clusters: selecione um cluster de cada vez e execute todos os passos restantes em todos os clusters: 
    kubectl -n cert-manager apply -f apigee-ca.yaml
  4. Exporte todos os certificados existentes disponíveis no espaço de nomes apigee para um ficheiro de cópia de segurança: 
    kubectl -n apigee get certificates --all -o yaml > all-certificates.yaml
  5. Execute o seguinte comando cmctl para reemitir todos os certificados encontrados no espaço de nomes apigee: 
    cmctl renew --namespace=apigee --all

    Exemplo de resultado:

    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

    Este passo deve reemitir todos os certificados de tempo de execução do Apigee com o certificado da AC do Apigee importado recentemente e isso deve resolver este problema.

  6. Verifique a data de emissão de todos os certificados em relação à hora UTC e confirme se foram reemitidos: 
    kubectl get certificates -n apigee -o json | jq -r '.items[] | "\(.metadata.name): \(.status.notBefore)"'
date -u

    Exemplo de resultado:

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