perivarlura / gentoo-containers

Containerfiles (or Dockerfiles) for building Gentoo and applications with ~amd64, different micro architecture levels and added useful utilities

Gentoo for GenZ

This is based on official Gentoo stage3 of amd64-nomultilib-systemd-mergedusr

Features

• Keyword updated to ~amd64
• Ready-made directory structure for /etc/portage
• Optimized for x86-64-v2 and x86-64-v3 microarchitectures
• Globally compiled with lto, pgo, graphite USE flags
• Recompiled whole stage3 from scratch so that every package is optimized.
• Essential utilities added (htop, tmux, bash-completion..etc)

Usage

• Mandatory flags: --mount type=tmpfs,tmpfs-size=75%,destination=/tmp --mount type=tmpfs,tmpfs-size=75%,destination=/var/tmp
• Optional but recommended flags: --volume gentoo_repos:/var/db/repos --volume gentoo_distfiles:/var/cache/distfiles --volume gentoo_binpkgs:/var/cache/binpkgs
• Which image tag to use depends on microarchitecture level of CPU. Run this command to know. /lib*/ld-linux-x86-64.so* --help | grep -i supported, if that doesn't work for some reason, use curl -sL https://raw.githubusercontent.com/HenrikBengtsson/x86-64-level/develop/x86-64-level | bash -s - --verbose
