Node CCE Agent Versions

Check Item

Check whether cce-agent on the current node is of the latest version.

Solution

• Scenario 1: The error message "you cce-agent no update, please restart it" is displayed.

  cce-agent does not need to be updated but is not restarted. In this case, log in to the node and manually restart cce-agent.

  Solution: Log in to the node and run the following command:

  systemctl restart cce-agent

  Perform the pre-upgrade check again.

• Scenario 2: The error message "your cce-agent is not the latest version" is displayed.

  cce-agent is not of the latest version, and the automatic update failed. This issue is typically caused by an invalid OBS path or the component version is outdated.

  Solution

  1. Log in to a node where the check succeeded, obtain the path of the cce-agent configuration file, and obtain the OBS address.

     cat `ps aux | grep cce-agent | grep -v grep | awk -F '-f ' '{print $2}'`

     The OBS configuration address field in the configuration file is packageFrom.addr.

  2. Log in to a where the check failed, obtain the OBS address again by referring to the previous step, and check whether the OBS addresses are the same. If they are different, change the OBS address of the abnormal node to the correct address.
  3. Run the following commands to download the latest binary file:
     • x86

       curl -k "https://{OBS address you have obtained}/cluster-versions/base/cce-agent" > /tmp/cce-agent

     • Arm

       curl -k "https://{OBS address you have obtained}/cluster-versions/base/cce-agent-arm" > /tmp/cce-agent-arm

  4. Replace the original cce-agent binary file.
     • x86

       mv -f /tmp/cce-agent /usr/local/bin/cce-agent
       chmod 750 /usr/local/bin/cce-agent
       chown root:root /usr/local/bin/cce-agent

     • Arm

       mv -f /tmp/cce-agent-arm /usr/local/bin/cce-agent-arm
       chmod 750 /usr/local/bin/cce-agent-arm
       chown root:root /usr/local/bin/cce-agent-arm

  5. Restart cce-agent.

     systemctl restart cce-agent
