What user are you running ebuildtester as? Can you run

docker run hello-world

as that user?

[RafaelPalomar]

docker run hello-world works fine as the same user invoking ebuildtester

[RafaelPalomar]

@nicolasbock, I think it is the configuration on my machine. I'll do some more testing and close the issue if it is related to my configuration.

[nicolasbock]

Ok, thanks. Let me know how it goes.

[RafaelPalomar]

Totally my setup. Sorry for the noise

[nicolasbock]

No worries 😄
