- Create a new namespace for the backup system - Implement a cron job for scheduled backups - Add a daemon set to handle backup tasks across nodes - Introduce necessary service accounts, roles, and role bindings - Include environment variable handling and configuration via secrets and config maps - Ensure triggering and execution workflow for backups is efficient This commit establishes a new backup system that utilizes both a cron job and a daemon set to automate backups. It organizes the configurations and credentials needed for S3-compatible storage, allowing for seamless backup management across the specified nodes in the Kubernetes cluster.
