Hello

error: error loading config file "/home/cloud_user/.kube/config": open /home/cloud_user/.kube/config: permission denied

each kubectl command is giving this error. i installed with sudo on system based on new labs.

i ran the sh scripts on both master and worker node as per labs.

please advise.

Thanks
Santosh

    Hi @santoshsub123,

    ... i installed with sudo on system based on new labs. ...

    You may have applied restrictive root permissions on resources required by cloud_user.

    What is the output of the following command?

    ls -la /home/cloud_user

    Regards,

    Hi @santoshsub123,

    It seems you ran the k8sMaster.sh script as root or with sudo, and in the process the .kube directory and possibly its contents are now owned by root instead of cloud_user, producing the permission error you posted earlier.

    You would need to change the ownership of the .kube directory and its content from root to cloud_user to fix the access permission issue.

    Regards,
    -Chris
