Error creating new Container App

[BigMorty]

Repro Steps

• Right clicked on my new CA env I just created and selected 'Create Container App...'
• Name - 'first-app'
• Cont Reg - ACR - 'mikemortACR'
• Repository - 'orderproc'
• Tag = '3.0'
• HTTP endpoint - 'Enable'
• Traffic - 'External'
• Port - '80'

Received the following error...
Error: The following field(s) are either invalid or missing. Invalid value: "orderproc-3.0": Invalid Name: Per RFC 1123 name must consist of lower case alphanumeric characters or '-', and must start and end with an alphanumeric character (e.g. 'my-name', or '123-abc', regex used for validation is 'a-z0-9?'): template.containers.

I tried a few other attempts, the pattern I see is it fails if the tag I select is something like 3.0 or 2.2. If I select a tag without a period in it, it works.

Likely because the . creates an invalid hostname.

Also need to verify other name requirements. For instance, there's a limit of 2–20 characters enforced in VS Code but longer names are allowed.
