$CurrentContainer cannot be initialized when `-only-exposed` is used

If using docker-gen
and nginx
separately instead of nginx-proxy
, the official template does not work when -only-exposed
(or -only-published
) is used.
After debugging, I found out that the root cause is $CurrentContainer
is not initialized properly. This is expected because the docker-gen
container does not expose any ports. So
{{ $CurrentContainer := where $ "ID" .Docker.CurrentContainerID | first }}
cannot find the docker-gen
container inside $
(the list of all containers)
A possible solution is to explicitly expose .CurrentContainer
as a top-level argument to the template.
