These little tweaks are little saviours when scalling up, if only a bit. That example above should be most telling – with no need to “fix” it in the yaml each time I build in different env / different host. I sroogled and I see examples which claim that such simple substitution should work for YAM…

I don’t believe that launcher will replace those ENV variables. It’s possible to build an image and then launch the same image multiple times with different domain names. You can ./launcher start-cmd app To see what ENV is needed to launch. To do it with a host that hasn’t bootstrapped, you’ll ne…
