Products

• VMware vSphere Kubernetes Service

Issue/Introduction

• When creating a new namespace and and entering a name for the namespace, it throws an error: "Input does not match the requirements"
• Checking the info option near the "Name" field shows the below requirements:
  • Alphanumeric (a-z and 0-9) string with maximum length of 63 characters
  • '-' character allowed anywhere except the first or last character
  • Must be unique across all Supervisors within a vCenter Server

Environment

vSphere Kubernetes Service

Resolution

• The namespace name should be a DNS-compliant name, which means it should meet the below requirements and must be in lower case:
  
  • Alphanumeric (a-z and 0-9) string with maximum length of 63 characters
  • '-' character allowed anywhere except the first or last character
  • Must be unique across all Supervisors within a vCenter Server

          Example: my-dev-namespace is valid; MyDevNamespace or my_dev_namespace are invalid
