This chapter includes common concepts on working with CaaS Infrastructure. What to read next MachineHealthChecksMachineHealthCheck is a controller that provides health monitoring and auto-repair facilities for machines. It is automatically deactivated in all management and workload clusters, for both control plane and worker nodes. You can specify conditions for determining when machines in a cluster are considered unhealthy using a MachineHealthCheck resource. Machines that meet these conditions are automatically remediated. Topology Variable ReferenceThis section lists variables that are common to all target platforms. These variables may apply to workload clusters, node pools, or both. Anti-affinity RulesAnti-affinity rule for K8s worker nodes is enabled in VMware Telco Cloud Automation by default. Anti-affinity is specific to workload clusters and ensures that the nodes deployed are spread across different hosts. Parent topic: Working with CaaS Infrastructure
