+# # StarRocks on Minikube
+# The yaml deploys a pair of starrocks `fe` and `be` services on k8s cluster. 
+# 
+# Prerequisites:
+# - valid minikube cluster
+# 
+# Deploy hints:
+# - it's OK to use host names of services in http api calls
+# - only fully qualified domain names (FQDNs) or IP addresses are reliable for interactions between starrocks 'fe' and 'be'
+# - the `fe` and `be` communicate with each other in both directions, so their FQDNs should be valid and resolvable
+# 
+# Topology:
+# ```mermaid
+# stateDiagram
+#   state MiniKubeCluster {
+#       fe_deployment --> fe_service
+#       be_deployment --> be_service
+#       be_deployment --> fe_deployment
+#       fe_deployment --> be_deployment
+#     }
+#   fe_service --> ExternalApp
+#  ```
+# 
+# ## Usage
+# 
+# Create resources labeled with "demo=starrocks-pair":
+# ```shell
+# kubectl apply -f minikube-starrocks-fe-be-pair-fqdn.yaml
+# ```
+#
+# Check status of the deployments:
+# (The `fe` sql service is ready for data loading once all deployments are available.)
+# ```shell
+# kubectl get deployment.apps --selector=demo=starrocks-pair
+# ```
+#
+# Get external ips of the services, which could be used to access the services:
+# ```shell
+# kubectl get service --selector=demo=starrocks-pair
+# ```
+#
+# Delete all resources created by this yaml:
+# ```shell
+# kubectl delete -f minikube-starrocks-fe-be-pair-fqdn.yaml
+# ```
+# Or:
+# ```shell
+# kubectl delete all --selector=demo=starrocks-pair
+# kubectl delete configmap --selector=demo=starrocks-pair
+# ```
+#
+# Software versions:
+# - minikube v1.30.1(Kubernetes v1.26.3, Docker 20.10.23_
+# - starrocks v2.5.4
