4.2. 監査ログの表示

それぞれのマスターノードについて OpenShift Container Platform API サーバーまたは Kubernetes API サーバーのログを表示することができます。

手順

監査ログを表示するには、以下を実行します。

  1. OpenShift Container Platform API サーバーログを表示します。

    1. 必要に応じて、表示する必要のあるログのノード名を取得します。

      $ oc adm node-logs --role=master --path=openshift-apiserver/
      
      ip-10-0-140-97.ec2.internal audit-2019-04-09T00-12-19.834.log
      ip-10-0-140-97.ec2.internal audit-2019-04-09T11-13-00.469.log
      ip-10-0-140-97.ec2.internal audit.log
      ip-10-0-153-35.ec2.internal audit-2019-04-09T00-11-49.835.log
      ip-10-0-153-35.ec2.internal audit-2019-04-09T11-08-30.469.log
      ip-10-0-153-35.ec2.internal audit.log
      ip-10-0-170-165.ec2.internal audit-2019-04-09T00-13-00.128.log
      ip-10-0-170-165.ec2.internal audit-2019-04-09T11-10-04.082.log
      ip-10-0-170-165.ec2.internal audit.log
    2. 特定のマスターノードとタイムスタンプの OpenShift Container Platform API サーバーのログを表示したり、そのマスターのすべてのログを表示します。

      $ oc adm node-logs <node-name> --path=openshift-apiserver/<log-name>

      以下は例になります。

      $ oc adm node-logs ip-10-0-140-97.ec2.internal --path=openshift-apiserver/audit-2019-04-08T13-09-01.227.log
      $ oc adm node-logs ip-10-0-140-97.ec2.internal --path=openshift-apiserver/audit.log

      以下のような出力が表示されます。

      {"kind":"Event","apiVersion":"audit.k8s.io/v1","level":"Metadata","auditID":"ad209ce1-fec7-4130-8192-c4cc63f1d8cd","stage":"ResponseComplete","requestURI":"/api/v1/namespaces/openshift-kube-controller-manager/configmaps/cert-recovery-controller-lock?timeout=35s","verb":"update","user":{"username":"system:serviceaccount:openshift-kube-controller-manager:localhost-recovery-client","uid":"dd4997e3-d565-4e37-80f8-7fc122ccd785","groups":["system:serviceaccounts","system:serviceaccounts:openshift-kube-controller-manager","system:authenticated"]},"sourceIPs":["::1"],"userAgent":"cluster-kube-controller-manager-operator/v0.0.0 (linux/amd64) kubernetes/$Format","objectRef":{"resource":"configmaps","namespace":"openshift-kube-controller-manager","name":"cert-recovery-controller-lock","uid":"5c57190b-6993-425d-8101-8337e48c7548","apiVersion":"v1","resourceVersion":"574307"},"responseStatus":{"metadata":{},"code":200},"requestReceivedTimestamp":"2020-04-02T08:27:20.200962Z","stageTimestamp":"2020-04-02T08:27:20.206710Z","annotations":{"authorization.k8s.io/decision":"allow","authorization.k8s.io/reason":"RBAC: allowed by ClusterRoleBinding \"system:openshift:operator:kube-controller-manager-recovery\" of ClusterRole \"cluster-admin\" to ServiceAccount \"localhost-recovery-client/openshift-kube-controller-manager\""}}
  2. Kubernetes API サーバーログを表示します。

    1. 必要に応じて、表示する必要のあるログのノード名を取得します。

      $ oc adm node-logs --role=master --path=kube-apiserver/
      
      ip-10-0-140-97.ec2.internal audit-2019-04-09T14-07-27.129.log
      ip-10-0-140-97.ec2.internal audit-2019-04-09T19-18-32.542.log
      ip-10-0-140-97.ec2.internal audit.log
      ip-10-0-153-35.ec2.internal audit-2019-04-09T19-24-22.620.log
      ip-10-0-153-35.ec2.internal audit-2019-04-09T19-51-30.905.log
      ip-10-0-153-35.ec2.internal audit.log
      ip-10-0-170-165.ec2.internal audit-2019-04-09T18-37-07.511.log
      ip-10-0-170-165.ec2.internal audit-2019-04-09T19-21-14.371.log
      ip-10-0-170-165.ec2.internal audit.log
    2. 特定のマスターノードとタイムスタンプの Kubernetes API サーバーログを表示したり、そのマスターのすべてのログを表示します。

      $ oc adm node-logs <node-name> --path=kube-apiserver/<log-name>

      以下は例になります。

      $ oc adm node-logs ip-10-0-140-97.ec2.internal --path=kube-apiserver/audit-2019-04-09T14-07-27.129.log
      $ oc adm node-logs ip-10-0-170-165.ec2.internal --path=kube-apiserver/audit.log

      以下のような出力が表示されます。

      {"kind":"Event","apiVersion":"audit.k8s.io/v1","level":"Metadata","auditID":"ad209ce1-fec7-4130-8192-c4cc63f1d8cd","stage":"ResponseComplete","requestURI":"/api/v1/namespaces/openshift-kube-controller-manager/configmaps/cert-recovery-controller-lock?timeout=35s","verb":"update","user":{"username":"system:serviceaccount:openshift-kube-controller-manager:localhost-recovery-client","uid":"dd4997e3-d565-4e37-80f8-7fc122ccd785","groups":["system:serviceaccounts","system:serviceaccounts:openshift-kube-controller-manager","system:authenticated"]},"sourceIPs":["::1"],"userAgent":"cluster-kube-controller-manager-operator/v0.0.0 (linux/amd64) kubernetes/$Format","objectRef":{"resource":"configmaps","namespace":"openshift-kube-controller-manager","name":"cert-recovery-controller-lock","uid":"5c57190b-6993-425d-8101-8337e48c7548","apiVersion":"v1","resourceVersion":"574307"},"responseStatus":{"metadata":{},"code":200},"requestReceivedTimestamp":"2020-04-02T08:27:20.200962Z","stageTimestamp":"2020-04-02T08:27:20.206710Z","annotations":{"authorization.k8s.io/decision":"allow","authorization.k8s.io/reason":"RBAC: allowed by ClusterRoleBinding \"system:openshift:operator:kube-controller-manager-recovery\" of ClusterRole \"cluster-admin\" to ServiceAccount \"localhost-recovery-client/openshift-kube-controller-manager\""}}
