How to test

[fharper]

@Seven45 Thanks for the PR, I'll test it today and get back to you.

FYI, @jokestax is fixing something else for Vultr that need to be fixed before we can test this PR. Once it's done, he will also test this one.

[fharper]

His PR was merged, so I'll be able to test this one.

I'll need to give it another try tomorrow. I had an issue that isn't related to this PR.

[jokestax]

@fharper @Seven45 the issue is fixed in #794

[fharper]

@jokestax: let us know when it's merged so we can test this PR again. Sorry for the delay @Seven45

[jokestax]

@fharper that pr solves the issue,i have upgraded it to 1.30,so you can test that branch itself:)

@Seven45 so sorry but someone else on the team updated the Kubernetes version by fixing another issue, which mean this PR has now no changes, or would have been a version lower than what we decided to use.

I'm so sorry, would have love to merge your commit as a contributor. With that said, thanks a lot for this PR as it helped us find that Vultr wasn't working anymore. We are implementing better daily testing to ensure this does not happen anymore.

Even if I need to close this PR, I consider you a contributor, and would love to send you some swag as a token of our appreciation. Can you ping me on our Slack community (I'm @fred) or by email at fred@kubefirst.io.
