Kubernetes Controller Cleaner
What is k8s-cleaner?
The Kubernetes controller Cleaner (k8s-cleaner) identifies, removes, or updates stale/orphaned or unhealthy resources to maintain a clean and efficient Kubernetes cluster.
It is designed to handle any Kubernetes resource types (including custom Kubernetes resources) and provides sophisticated filtering capabilities, including label-based selection and custom Lua-based criteria.
Features and Capabilities
1️⃣ Schedule: Specify the frequency at which the k8s-cleaner should scan the cluster and identify stale resources. Utilise the Cron syntax to define recurring schedules.
2️⃣ DryRun: Enable safe testing of the k8s-cleaner filtering logic without affecting actual resource configurations. Resources matching the criteria will get identified, but no changes will get applied.
3️⃣ Label Filtering: Select resources based on user-defined labels, filtering out unwanted or outdated components. Refine the selection based on label key, operation (equal, different, etc.), and value.
4️⃣ Lua-based Selection Criteria: Leverage the Lua scripting language to create complex and dynamic selection criteria, catering to specific resource management needs. Define custom logic to identify and handle stale resources.
5️⃣ Notifications: Stay informed! The k8s-cleaner keeps users in the loop about every cleaned-up resource, whether removed or optimized. Get detailed notification lists and pick your preferred channel: Slack, Webex, Discord, Teams or reports.
Benefits
💪 Resource Removal: Efficiently remove stale resources from your cluster, reclaiming unused resources and improving resource utilisation.
💪 Resource Updates: Update outdated resources to ensure they align with the latest configurations and maintain consistent functionality.
💪 Reduced Resource Bloat: Minimize resource bloat and maintain a clean and organized cluster, improving overall performance and stability.
By combining the flexibility of scheduling, the accuracy of label filtering, the power of Lua-based criteria, and the ability to remove or update stale resources, the k8s-cleaner empowers users to effectively manage Kubernetes environments and optimise resource usage.
Contribute
We encourage everyone to contribute to the example directory by adding new Cleaner configurations 💡. This will help the community benefit from different expertise and build a stronger knowledge base of the Cleaner use cases.
🤝 Together we can expand the range of Cleaner applications and make it an even more valuable tool for managing Kubernetes resources efficiently.
