Use valid registry names#

Operational Excellence · Container Registry · 2020_06

Container registry names should meet naming requirements.


When naming Azure resources, resource names must meet service requirements. The requirements for container registry names are:

  • Between 5 and 50 characters long.
  • Alphanumerics.
  • Container registry names must be globally unique.


Consider using names that meet container registry naming requirements. Additionally consider naming resources with a standard naming convention.


This rule does not check if container registry names are unique.
