Key Commands of Nodes

Check Items

Whether some key commands that the node upgrade depends on are working

Solution

• Scenario 1: Executing the package manager command failed.

  Executing the rpm or dpkg command failed. In this case, log in to the affected node and check whether the following commands are available:

  • rpm:

    rpm -qa

  • dpkg:

    dpkg -l

• Scenario 2: The systemctl status command fails to be executed.

  If the systemctl status command on a node is unavailable, many check items will be affected. Log in to the node and check the availability of the following commands:

  systemctl status kubelet
