backend="[varnish]:8443" fails

[sudazzle]

with docker-compose varnish and hitch as a service. configuring backend="[varnish]:8443" exits hitch with following error:
hitch_1 | 20210818T221921.192188 [ 1] {getaddrinfo-backend}: Name or service not known.

hum, so I would expect hitch to resolve the address as it needs to open the connection, so that shouldn't prevent it from starting. But if it does, you should report it to https://github.com/varnish/hitch

But anyway, it seems that the varnish container isn't up yet, so the hostname resolution fails, can you try using depends_on to tell the hitch container to wait on the varnish one (same way it's done here) If it solves it, please consider sending a PR to https://github.com/varnish/toolbox

[gquintard]

after testing I can confirm this, and it's not a docker-compose issue, it's that hitch really wants the address to be resolved to be resolved before starting.

Can you open a hitch issue please? For the container use-case, depends_on should work, but I'll wait for your confirmation before closing this

depends_on works.

thanks @sudazzle !
