node-selectors.yaml

# This YAML file defines node selectors, tolerations, and affinities for deploying SystemLink Enterprise.
# The global section specifies selectors for different types of services (e.g., systemlink services, Jupyter, Dremio)
# and includes tolerations for handling tainted nodes. Each service-specific configuration section utilizes
# these global values through anchors (*), ensuring consistency and reducing duplication.
#
# When deploying the application, this file should be combined with other values.yaml files that may define
# additional configurations specific to each service, such as resource requests, limits, or environment variables.
# The node selectors ensure that pods are scheduled on the appropriate nodes, while tolerations allow for
# flexibility with node taints, and affinities enforce specific node requirements.
#
# Default values are provided here for node selectors and tolerations.  Change them if needed to match the
# node labels and taints for your kubernetes cluster.
