R-base for PowerPC? #409

Closed Someone894 closed 4 years ago

Someone894 commented 4 years ago

Hello everyone,

for some time now I'm using your R-base image on my amd64 server. For about the same time I use your code as a basis for my own r-base image on an PowerPC 8 machine. But lately this approach got more and more troublesome.

This leads me to the question: Is it possible for you to supply the R-Base image for the PowerPC architecture as well?

This would be great. Thank you for your time :-)

Does Docker Hub support builds for the cpu used on your PowerPC? I.e. what Debian calls ppc64el?

Otherwise there is always a direct installation of Debian on ppc64el. Gets you exactly the same R packages as I maintain those in Debian where they are built for 20 or so architectures.

Sorry, but I don't really understand your question.

At the moment I am taking this file and change the FROM debian:testing line to FROM ppc64le/debian. Then I hope, that it completes without any errors.

And now I was wondering if you could add a ppc66le version of your R-Base package to Dockerhub. This way it would be tested and work more stable then my version. In addition to that other people could use it as well.

No because I cannot have two versions of the same file.

What I can do is turn on two or more architectures to build from the same file. That is how we support standard Intel x64 (called, confusingly, amd64) plus and arm variant arm64v8:

Architectures: amd64, arm64v8

My question to you was (and still is) whether ppc64le is supported by Docker Hub? If so I can add it. If not, there is little I can do for you.

The ppc64le/debian base image I use is from dockerhub, so I think it is possible to deploy ppc64le via dockerhub.

I also found some documentation here which suggests that ppc64le is part of "Other architectures built by official images: (but not officially supported by Docker, Inc.)".

Therefore I think that ppc64le is supported by Docker Hub.

Thanks for the documentation pointer -- that was exactly what I needed.

PR filed, if and when it is merged by the Docker maintainers you will get r-base for ppc64le.

This has been merged upstream so you should have r-base for pp64le now, or "very soon".
