port label validation doesn't filter invalid characters

[deepbluemussel]

Nomad version

Nomad v1.2.6 (a6c6b475db5073e33885377b4a5c733e1161020c)

Issue

Any character is accepted in the name parameter of the stanza network. The job is applied without syntax errors and Nomad's GUI even displays the name with special characters.

However, this should not be possible if we refer to the control here.

On the other hand, Levant applies the check correctly and raises the syntax error.

Expected Result

Port label does not conform to naming requirements ^[a-zA-Z0-9_]+$

Actual Result

No issue is raised. Job is applied without errors.

Job file (if appropriate)

    network {
      port "myport,#!)'8" {
         to     = 8080
       } 
    }

Hi @deepbluemussel. I suspect that particular regex validation may no longer be used with the move to HCL2. But that's certainly a bug to fix.

@tgross we also are seeing this error in Levant. Can you advise on this thread as well?

Additionally, in general, - We also have a large community of people waiting for an answer on this thread. Can you advise?

Thank you!!!

@brettplarson my colleague James has responded on hashicorp/levant#448. The discuss thread seems to be unrelated to this issue entirely. Unfortunately I don't have an official answer for you, either. But let's try to keep issues on topic please.
