Mocaccino OS Luet Tree for Gentoo Portage

Development notes

Generate provides for a package:

First be sure to have yq, jq and pkgs-checker installed ( luet install repository/mocaccino-extra-stable and luet install -y utils/yq utils/jq dev-util/pkgs-checker-minimal )

$ DOCKER_HOST=ssh://10.16.0.51 PACK=layers/X make gen-provides

Inspect docker images from packages

To retrieve the docker images hashes of the packages, you can run:

$ luet tree images --image-repository quay.io/mocaccinocache/portage-amd64-cache --tree amd64 --tree multi-arch layers/system-x

layer/gentoo-stage3-0.20201125: quay.io/mocaccinocache/portage-amd64-cache:e1eb7be13068a1fb7956b4b68d20e74f9033956b453a2fbc7436e0dab28e50c2

To run a container for debugging, then you can :

DOCKER_HOST=ssh://10.16.0.51 docker run --rm -ti quay.io/mocaccinocache/portage-amd64-cache:14ecb8f06592144484d3a103002894c36c115dd372953399d7afa0ecb05a1f82

Retrieve the list of files owned by a package

$> yq r /var/cache/luet/repos/mocaccino-portage/metafs/repository.meta.yaml 'index' -j | jq '.[] | select(.compilationspec.package.name=="system-core" and .compilationspec.package.category=="layers") | .files[]' -r

Best practices for layers packages

To trace correctly what are the packages created inside a layer, it's a good practice is to add inside the layer data the list of the installed packages:

• /usr/share/mocaccino/layer/<layer-name>.prelude.pkglist: This file contains the list of the packages list before the build.

• /usr/share/mocaccino/layer/<layer-name>.pkglist: This file contains the list of the packages list after the build.
