Hi,
I'm trying to follow the tutorial at
cloudcore component init fine on the cloud machine, however, when trying to setup the edge machine by executing keadm join --cloudcore-ipport=..... command, the command executed successfully but the edge node does not join the cluster.
By looking into the logs, it seems the error is caused by following failed environment check:
Failed to check the running environment: lstat /proc/kmsg: permission denied
Any idea how to solve this issue?
OS: CentOS 8 Core
keadm built from latest code at https://github.com/kubeedge/kubeedge
Golang version: 1.14.4.linux-amd64

Does the edgenode run with root user?

Yes fisher, the "keadm init ..." commad was executed with root user login and with "[root@kubeedge-edge1 ~]#" bash prompt.
