# Example values.yaml:
# resources:
# %{camelName}:
# replicas: 2 # Note: 2 replicas will also add a small third tiebreaker node
# # Instead of using just a number to specify the number of replicas, we use
# # a list of names. This allows controlling exactly which replica gets shut down
# # when scaling down, which is useful when eg. decommissioning a node.
# # Note: 2 replicas will also add a small third tiebreaker node
# namedReplicas:
# - replica1
# - replica2
# memory: 1Gi # Provide at least 1Gi of RAM to avoid OOM kills
# cpu: 1
# disk: 10Gi
