가능한 원인

원인 설명 다음에 관한 문제 해결 안내
Apigee CA 인증서가 Apigee 클러스터 간에 일치하지 않음 클러스터 간에 Apigee CA 인증서가 일치하지 않으면 Cassandra의 TLS 인증서 확인에 실패할 수 있습니다. Apigee Hybrid

기본 요건

  • Apigee 클러스터에 액세스하려면 kubectl을 설치하고 구성해야 합니다.
  • JSON 콘텐츠의 형식을 지정하려면 jq가 필요합니다.
  • TLS 인증서를 인쇄하려면 keytool이 필요합니다.
  • Cert Manager를 사용하여 인증서를 재발급하려면 cmctl이 필요합니다.

원인: Apigee 클러스터 간에 Apigee CA 인증서가 일치하지 않음

진단

  1. 다음 명령어를 사용하여 apigee-ca 보안 비밀을 읽고 모든 클러스터의 Apigee CA 인증서를 출력합니다. 
    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d | keytool -printcert | grep Version -B 10

    출력 예시는 다음과 같습니다.

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

  2. apigee-cassandra-default-tls 보안 비밀을 읽고 Cassandra 인증서를 생성할 때 위의 Apigee CA 인증서가 사용되었는지 확인합니다. apigee-cassandra-default-tls 보안 비밀에는 ca.crt 아래에 Apigee CA 인증서가 포함되어 있습니다. 
    kubectl -n apigee get secret apigee-cassandra-default-tls -o json | jq -r '.data["ca.crt"]' | base64 -d | keytool -printcert | grep Version -B 10

    출력 예시는 다음과 같습니다.

  3. 위 예에서 apigee-ca 보안 비밀에 있는 Apigee CA 인증서의 일련번호는 apigee-cassandra-default-tls 보안 비밀(afcc2ef957cebfd52b118b0b1622021)에 있는 Apigee CA 인증서와 일치합니다. 이는 Cassandra 인증서가 동일한 Apigee CA 인증서로 서명되었음을 확인합니다. 아래 단계에 따라 이를 추가로 확인할 수 있습니다.
  4. Apigee CA 인증서 pem 파일을 추출합니다. 
    kubectl -n cert-manager get secret apigee-ca -o json | jq -r '.data["tls.crt"]' | base64 -d > apigee-ca.crt

    출력 예시는 다음과 같습니다.

    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. Apigee CA 인증서를 사용하여 Cassandra 인증서를 확인합니다. 
    openssl verify -CAfile apigee-ca.crt apigee-cassandra-default-tls.crt

    성공적인 출력 예시:

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

    실패 출력 예시:

    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

해결 방법

  1. 올바른 Apigee CA 인증서가 있는 Apigee 클러스터를 선택합니다.
  2. 해당 클러스터에서 Apigee CA 인증서 보안 비밀을 파일로 내보냅니다. 
    kubectl -n cert-manager get secret apigee-ca -o yaml > apigee-ca.yaml
  3. 한 번에 하나씩 클러스터를 선택하여 위의 Apigee CA 인증서 보안 비밀을 다른 모든 클러스터에 적용하고 모든 클러스터에서 나머지 모든 단계를 실행합니다. 
    kubectl -n cert-manager apply -f apigee-ca.yaml
  4. apigee 네임스페이스에서 사용 가능한 모든 기존 인증서를 백업 파일로 내보냅니다. 
    kubectl -n apigee get certificates --all -o yaml > all-certificates.yaml
  5. 다음 cmctl 명령어를 실행하여 apigee 네임스페이스에 있는 모든 인증서를 재발급합니다. 
    cmctl renew --namespace=apigee --all

    출력 예시는 다음과 같습니다.

    cmctl renew --namespace=apigee --all

    이 단계에서는 새로 가져온 Apigee CA 인증서를 사용하여 모든 Apigee 런타임 인증서를 재발급해야 하며, 그러면 이 문제가 해결됩니다.

  6. 모든 인증서의 발급 날짜를 UTC 시간과 비교하여 재발급되었는지 확인합니다. 
    kubectl get certificates -n apigee -o json | jq -r '.items[] | "\(.metadata.name): \(.status.notBefore)"'
date -u

    출력 예시는 다음과 같습니다.

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

    출력 예시는 다음과 같습니다.
