Cluster Operations

Update Planning: Plan OpenShift cluster updates including scheduling, testing, and rollback strategies

Pre-update Validation: Verify cluster health, node readiness, and workload compatibility before updates

Rolling Updates: Execute cluster updates using machine config pools and staged rollouts

Update Channels: Manage update channels (stable, fast, candidate) and version targeting

Post-update Verification: Validate cluster functionality and workload health after updates

Update Rollbacks: Execute rollback procedures when updates fail or cause issues

Node Scaling: Add worker nodes to increase cluster capacity based on resource demands

Infrastructure Nodes: Add dedicated infrastructure nodes for OpenShift components (registry, monitoring, logging)

Node Draining: Safely drain nodes before removal to migrate workloads without disruption

Node Cordoning: Cordon nodes to prevent new pod scheduling during maintenance or removal

Machine Sets: Manage machine sets to automate node provisioning and replacement

Node Decommissioning: Properly remove nodes from the cluster and clean up associated resources

Operating System Updates: Apply RHEL CoreOS updates through machine config operators

Base Image Rotation: Manage base node image updates and security patches

Machine Config Pools: Configure and manage machine config pools for different node types

Image Validation: Test new node images in development before production deployment

Rollback Procedures: Maintain ability to rollback to previous node images when issues occur

Custom Machine Configs: Create and manage custom machine configurations for specific requirements

GPU Resources: Configure and manage GPU nodes using NVIDIA GPU Operator or AMD GPU drivers

Device Plugins: Deploy and maintain Kubernetes device plugins for specialized hardware

Network Interfaces: Manage SR-IOV network devices and high-performance networking configurations

Resource Allocation: Configure device resource limits and scheduling for GPU/FPGA workloads

Driver Management: Maintain device drivers through machine configs and operator deployments

Device Monitoring: Monitor device utilization, temperature, and health status across nodes

Hardware Compatibility: Validate hardware compatibility and manage device firmware updates
