• dump multiple databases
• dump each database into a different file
• Kubernetes scheduled jobs examples for automatic backup of databases

Notes:

• Edit ConfigMaps and Secrets according to your environment. Values in secrets have to be base64 encoded.
• Edit the scheduledjobs definitions to set backup location or change the linux user:

1. To dump all databases use "mysqldump.scheduledjob.all.yaml" example. Also has an option to exclude one database from backup.

2. Create secret, configmap and job(s)

         kubectl create -f mysqldump/mysqldump.configmap.yaml
         kubectl create -f mysqldump/mysqldump.secret.yaml
         kubectl create -f mysqldump/mysqldump.scheduledjob.all.yaml
