@mfojtik you like --follow on deploy and you bringed this in, all yours : )

[mfojtik]

@Kargakis what other options we have to verify that the environment variables were expanded? Any method I can think of assumes that the container is/was running which might suffer with timeouts. But I think I'm slowly inclining to say that --follow is not a good idea for tests.

Also bumping this to P1 as we now track all flakes as P1.
