Tingjie, It looks like you are missing the --kubeconfig parameter for kubectl, which should point to the /etc/kubernetes/admin.conf file which contains the authentication credentials. However, it is better to use the python-kubernetes API instead of kubectl - take a look at the KubeOperator class in sysinv/common/kubernetes.py - that is our preferred way to communicate with the kubernetes API.

But I tried on my local Ubuntu environment, the result is OK. Is there any audit or privilege or some audit in Sysinv Service? Piece of code: execute_process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=sys.stderr) objects = yaml.safe_load(execute_process.stdout) if execute_process.wait() != 0: raise ApiError return objects Following is the output: ----------------------------------------------------- sysinv 2020-01-14 10:31:20.038 1172858 INFO sysinv.common.ceph [-] ceph osd crush rule ls sysinv 2020-01-14 10:31:20.038 1172858 ERROR rook_client_kubeapi [-] ['/usr/bin/kubectl', 'get', '--namespace', 'kube-system', 'pod', '-l', 'app=rook-ceph-tools', '-o', 'jsonpath="{.items[0].metadata.name}"'] sysinv 2020-01-14 10:31:20.038 1172858 INFO rook_client_kubeapi [-] Get pod command: ['/usr/bin/kubectl', 'get', '--namespace', 'kube-system', 'pod', '-l', 'app=rook-ceph-tools', '-o', 'jsonpath="{.items[0].metadata.name}"'] sysinv 2020-01-14 10:31:45.026 1172858 ERROR sysinv.common.ceph [-] Exception in ls crush rule: Command '['/usr/bin/kubectl', 'get', '--namespace', 'kube-system', 'pod', '-l', 'app=rook-ceph-tools', '-o', 'jsonpath="{.items[0].metadata.name}"']' returned non-zero exit status 1: CalledProcessError: Command '['/usr/bin/kubectl', 'get', '--namespace', 'kube-system', 'pod', '-l', 'app=rook-ceph-tools', '-o', 'jsonpath="{.items[0].metadata.name}"']' returned non-zero exit status 1 sysinv 2020-01-14 10:31:45.027 1172858 ERROR sysinv.openstack.common.rpc.amqp [-] Exception during message handling: CephFailure: OSD crush rule ls failed.
