Thanks for this contribution! Please also update to 2 the integer here https://github.com/k3s-io/k3s/blob/master/tests/e2e/tailscale/tailscale_test.go#L17

I can confirm that the file is correctly copied to the guest machine, however the tailscale key is not picked up from the env

did you run the test passing the tailscale key?

E2E_TAILSCALE_KEY=xxxxxx go test -v ./test/e2e/tailscale

[npitsillos]

no I just exported it as an environment variable

[manuelbuil]

Are you testing this? Is it working for you?

[npitsillos]

I just managed to run the tests I had issues with running vagrant without sudo. The tests fail but I should rebase my branch with the latest changes that have your code for it right?

What's the error you get?

[manuelbuil]

Could you please rebase? That will include my fix :)

[npitsillos]

Just rebased from master and pushed the changes

[manuelbuil]

I have just tested and works :). Thanks again @npitsillos
