What Should I Do If Sandbox-Related Errors Are Reported When the Pod Remains in the Creating State?

Symptom

The pod remains in the creating state for a long time, and the sandbox-related errors are reported.

Solution

Select a troubleshooting method for your cluster:

Clusters of V1.13 or later

  1. Sandbox errors are generally caused by the abnormal startup of the container component on the node. You can run the systemctl status canal command to check the container component and run the systemctl restart canal command to restart the component.
  2. All container components on the node are normal, but the loopback file of the CNI is missing. The error is as follows: network: failed to find plugin "loopback" in path [/opt/cni/bin]. You can copy a complete version of the loopback file from the current region or other regions which share the same cluster versions (minor releases can be ignored), and put the loopback file in the path /opt/cni/bin/. Then, restart the canal component.

Clusters earlier than V1.13

  1. Sandbox errors are generally caused by the abnormal startup of the container components on the node. You can run the su paas -c '/var/paas/monit/bin/monit summary' command to check the container component and run the su paas -c '/var/paas/monit/bin/monit restart canal' command to restart the component.
  2. All container components on the node are normal, but the loopback file of the CNI is missing. The error is as follows: network: failed to find plugin "loopback" in path [/opt/cni/bin]. You can copy a complete version of the loopback file from the current region or other regions which share the same cluster versions (minor releases can be ignored), and put the loopback file in the path /opt/cni/bin/. Then, restart the canal component.
