What Can I Do If the Container Network Becomes Unavailable After yum update Is Used to Upgrade the OS?

The CCE console does not support OS upgrades on a node. You are advised not to upgrade the OS using the yum update command.

If you upgrade the OS using yum update, the container networking will be unavailable.

Perform the following operations to restore the container network:

This restoration method is valid only for EulerOS 2.2.

1. Run the following script as user root:

   #!/bin/bash
   function upgrade_kmod()
   {
       openvswicth_mod_path=$(rpm -qal openvswitch-kmod)
       rpm_version=$(rpm -qal openvswitch-kmod|grep -w openvswitch|head -1|awk -F "/" '{print $4}')
       sys_version=`cat /boot/grub2/grub.cfg | grep EulerOS|awk 'NR==1{print $3}' | sed 's/[()]//g'`
   
       if [[ "${rpm_version}" != "${sys_version}" ]];then
           mkdir -p /lib/modules/"${sys_version}"/extra/openvswitch
           for path in ${openvswicth_mod_path[@]};do
               name=$(echo "$path" | awk -F "/" '{print $NF}')
               rm -f /lib/modules/"${sys_version}"/updates/"${name}"
   			rm -f /lib/modules/"${sys_version}"/extra/openvswitch/"${name}"
               ln -s "${path}" /lib/modules/"${sys_version}"/extra/openvswitch/"${name}"
           done
       fi
   	depmod ${sys_version}
   }
   upgrade_kmod
   

2. Restart the VM.
