Hah, turns out I was comparing with the compressed size shown on Docker Hub. Before: 902MB |
|
Okay, a lot of this is down to me adding |
|
Thanks for digging into this. I will try to pick work back up on this soon. |

I've tried to take the same approach for Ubuntu, but APT is not playing ball at all. This doesn't surprise me much, to be honest. |

I don't think it's as critical for Ubuntu/Debian... "Build and push" is the install sunshine step... you can see here it's rather quick even with qemu. https://github.com/LizardByte/Sunshine/actions/runs/7664452338/job/20888787801 |

* Does not require QEMU at all! * Caches dnf metadata and downloads between rebuilds. * Respects TARGETARCH as a Docker variable, adding DNF_ARCH instead. * Reduces downloads and image size by ignoring weak dependencies. CUDA almost works. We borrow RHEL 8 packages for cross-compiling because this is the only distro with NVIDIA packages for ppc64le. Unfortunately, the toolkit doesn't support GCC 13, and forcing it leads to errors.

Works for amd64, arm64, and ppc64le. Unlike Fedora, this does require QEMU because APT seems incapable of operating on a different root directory for a different architecture. As with Fedora, cross-compiling CUDA works by borrowing the RHEL 8 packages because this is the only distro with NVIDIA packages for ppc64le.

Okay, think I'm about done now. |

Sorry, I just can't follow this diff. Half of items marked as new were already in the target branch. We also can't cache all the dependencies... we only get 10GB of cache, and regularly far exceed this as is.
I think I would rather just discuss what needs to change in #2020, rather than having a PR into it. |

Improvements to #2020 so that Fedora 39 now works.
The image is still a little large at 591MB, twice what you have now. I'm not sure why, but I don't think you were doingdnf updatebefore? That can bloat it quite a bit.I think you may need
setcapto give Sunshine the correct permissions, but you didn't seem to have this before?
