- Implement node affinity to prevent scheduling on vkvm-us2
- Update affinity section in daemonset.yaml
- Ensure that the DaemonSet runs only on specific nodes
This change introduces a node affinity rule to the DaemonSet configuration,
allowing it to avoid scheduling on nodes labeled with `kubernetes.io/hostname`
set to `vkvm-us2`. This helps to ensure resource allocation and performance
by restricting the DaemonSet to the desired nodes.
- Change TEMP_DIR to use a more structured temporary path
- Adjust rsync command to reflect the new directory structure
- Improve MSG_TEXT formatting for better clarity
- Add 'jq' to the dependencies for JSON processing
These changes address issues with the previous temporary directory location and enhance the output messages for a more informative backup success notification.
- Include a webhook URL to send notifications after backups.
- Capture and log the duration and size of the backups.
- Create a new Kubernetes secret for storing the Feishu webhook URL.
- Enhance the backup script to notify users of backup success with details.
This change improves monitoring and user notification of backup events,
allowing for better awareness and response times in case of failure or
success of the backup processes.
- 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.
- Create a cronjob to back up node1 data to node8
- Define schedule for daily backups at 3:00 AM
- Include error handling and notifications via Feishu
- Use SSH and rsync for secure and efficient data transfer
This commit introduces a new cronjob that automates the backup process
for node1 to node8, enabling easier management and recovery of data.
The setup includes necessary security measures and proper logging of backups,
ensuring smoother operation and notifications in case of failures.
