[RC2] [Functest K8s] sig-network TC set external access required

[sultetveny]

Hi,

it's not an issue, just a note/question. On air gapped environment (test labs, or customer site) where no direct access is available from the cluster, these tests failed. While proxy is available to connect to the outside world, unable to add it as a parameter.

Failed TCs:

• [Fail] [sig-network] Networking [It] should provide Internet connection for containers [Feature:Networking-IPv4]
  • nc -vz -w 30 8.8.8.8 53
• [Fail] [sig-network] Networking [It] should provider Internet connection for containers using DNS [Feature:Networking-DNS]
  • nc -vz -w 30 google.com 80

Maybe, with the same way as we add the mirror repository and other variables, we can add the proxy too? then netcat can use it too?

# content of the env file
...
QUAY_REPO=
https_proxy=
no_proxy=
...

Or we can say it's not applicable on air gapped environment. What do you think?
