Taints and tolerations, pod and node affinities demystified
Enterprises often use multi-tenant and heterogenous clusters to deploy their applications to Kubernetes. These applications usually have needs which require special scheduling constraints. Pods may require nodes with special hardware, isolation, or colocation with other pods running in the system.
The Pipeline platform allows users to express their constraints in terms of resources (CPU, memory, network, IO, etc.). These requirements are turned into infrastructure specifications using Telescopes. Once the cluster nodes are created and properly labeled by Pipeline, deployments are run with the specified constraints automatically on top of Kubernetes.
