Creating (SST) backups seem to fail on example configuration

Description

When I try to run a (manual) backup my backup job seems to fail to perform the SST.

I can't seem to find out why, but I have one hunch: I have IPv6 enabled in my cluster (dual stack). Maybe something is going wrong there.

I have attached:

  • My cr.yaml

  • My backup.yaml

  • The logs of the backup job

  • The (hopefully) relevant logs of the PXC pod that was responding to the SST

This is the error from that last file that pointed me towards IPv6:

If any more info is needed, please let me know!

I am using PXC image 8.0.26-16.1 and backup image 1.10.0-pxc8.0.25-backup.

Environment

I have created PR https://github.com/percona/percona-docker/pull/803 we have a plan to include it in our next PXCO release. You can review/test it as well.

I was facing the same issue with version 1.11.0 on dual stack kubernetes 1.24.

I found the script /usr/bin/backup.sh in image percona-xtradb-cluster-operator:1.11.0-pxc8.0-backup using $(hostname -i) to retrieve the pod's ip, which would be something like 

 

 

My workaround is using  $(hostname -i | sed 's/.* //') instead and making my own operator backup image.

The fixed

is attached. The only difference with the origin file is the $(hostname -i | sed 's/.* //') part.

Then make a workaround operator backup image with dockerfile like below:

Change the image of the backup section to your own one and the backup would be running smoothly again
