connection problem to openeocubes container

[Edzer Pebesma]

I was testing https://hub.docker.com/r/brianpondi/openeocubes - it runs remotely, but not locally; when the container runs locally, I run

docker run -p 8000:8000  --rm brianpondi/openeocubes

in one terminal, in another R:

> library(openeo)

I remember having problems with plumbeR in this regard. I could not use multiple endpoints at one service. Ideally you would have "http://127.0.0.1:8000" handle the service capabilities and then you have other endpoints like /processes, /jobs and so. And if I recall correctly, then I needed to end the capabilities query with /. But I need to run the container first to check, then I will report back.

See Open-EO/openeo-r-backend#17 for more

But the same container works on the AWS instance, right?

... and with the R client in version 1.1-0!

I found out that there was an issue with the capabilities request, which not only affected the openeocubes container, but also openeo.cloud. However, on the latter it did not result in an error. The fix for this was already contained in Matthias' PR.
