• RISC-V

  • We worked on supplying a RISC-V64 recent dockerd, docker, containerd, runc, docker compose set of Debian Trixie packages so anyone can have an up to date docker experience for Jenkins
  • RPM are now available, even if we know that Fedora and others do prefer podman. We need docker compose for our quickstart tutorials, though
  • Most of the existing RISC-V64 machines use derivatives of Debian or Fedora
  • We also supply ebuilds for Gentoo users
