Kubernetes 之 ConfigMap

语法规范

create

#  kubectl create -f spark-configMap.yaml
The ConfigMap "spark-configMap" is invalid: metadata.name: Invalid value: "spark-configMap": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

metadata 里 的value值都调整成小写

describe

# kubectl describe configmaps  spark-configmap
Name:         spark-configmap
