There are two issues fixed here:
1) The "backoffLimit" and "activeDeadlineSeconds" are attributes of
Job, not CronJob. Therefore, they should be placed in the Job template
part of the cron-job-backup-mariadb.yaml
2) The backup cronjob had two names in the values.yaml
"backup_mariadb" and "mariadb_backup" in various places.
3) When empty table is used, the get_rows function of
restore_mariadb.sh exit with a code of 1, which causes the invoking
function to error out.
