I shall not be dismissed like this! 😂 (or at least my approval shall not be dismissed :P)

[mfelsche]

it is not working yet anyways. For some reason on CI the elasticsearch docker image is not coming up properly with http ssl settings :( Still investigating with some heavy printf debugging

Oh no 😭 I'll just keep approving so you're not blocked on that.
