docker network name validation is not so strict #27449
Description
Description
As container name and volume name must be strict with regex [a-zA-Z0-9][a-zA-Z0-9_.-]. While network name is so casual that just not be empty. I think it is not so reasonable.
In addition, One confusion that why one character name for a container or volume is invalid. ping @vdemeester @vdemeester
Steps to reproduce the issue:
docker network create ^, it works
Describe the results you received:
It works.
root@ubuntu:~# docker network create ^
eb995b6be7ef87ce0ed14c6a8143e7bef1aa7627ab027475df304ec96588f0fd
Describe the results you expected:
docker: Error response from daemon: Invalid network name (^), only [a-zA-Z0-9][a-zA-Z0-9_.-] are allowed.
