[Feature] Customize prefix of name of the ephemeral generated namespace

[ChrisV404]

Problem Statement

Currently I have a need to run tests in a namespace with a certain prefix in the name. I'd still want to maintain the random name generated by Chainsaw as the suffix. The tests require certain Roles that exist in my cluster. The prefix will enforce isolation to block access of the namespace to anyone (or anything) that don't possess the valid Role.

Solution Description

I'd like to configure the prefix of the namespace at the Test spec level and in the Configuration file.

Potential solution at the Test spec level:

apiVersion: chainsaw.kyverno.io/v1alpha1
kind: Test
metadata:
  name: my-test
  labels:
    group: basic
spec:
  description: "First Test"
  namespace-prefix: "my-test"   # The namespace would look like: my-test-<random-string>-<random-string>

Potential solution in Configuration:

apiVersion: chainsaw.kyverno.io/v1alpha2
kind: Configuration
metadata:
  name: tests-config
spec:
  namespace-prefix: "my-test"

Alternatives

As of right now, I couldn't find any workaround for this.

Great idea, this would allow the user to override the default prefix of chainsaw.

Minor suggestion: maybe the new property name should be namespacePrefix instead of namespace-prefix to follow the convention of the other properties.

You can configure it in the config:

  namespace:
    template:
      metadata:
        name: (join('-', ['prefix', $namespace]))

Would this work ?
