That was not true! Here the situation: https://gitlab.com/debdistutils/guix/container/-/pipelines/1600726433 Debian fails on these two GitLab .gitlab-ci.yml variants: image: name: debian:stable entrypoint: ["/bin/sh"] image: name: debian:stable entrypoint: ["/bin/sh", "-c"] And works on these two variants: image: name: debian:stable entrypoint: [""] image: debian:stable The last one is what I suppose most people want to use. One shouldn't have to specify entrypoint's when using GitLab CI/CD images. My Guix container:latest works on these three variants: image: name: debian:stable entrypoint: ["/bin/sh", "-c"] image: name: debian:stable entrypoint: [""] image: debian:stable And fail on this variant: image: name: debian:stable entrypoint: ["/bin/sh"] At least we are not worse than Debian here. However there is another difference, local run of Debian images handle both these variants: jas@kaka:~/src/guix-container$ podman run -it --rm debian:trixie-slim root@f9634c8d6b63:/# exit jas@kaka:~/src/guix-container$ podman run --entrypoint /bin/sh -it --rm debian:trixie-slim # jas@kaka:~/src/guix-container$ But my Guix images doesn't: jas@kaka:~/src/guix-container$ podman run -it --rm registry.gitlab.com/debdistutils/guix/container:latest Error: no command or entrypoint provided, and no CMD or ENTRYPOINT from image jas@kaka:~/src/guix-container$ podman run --entrypoint /bin/sh -it --rm registry.gitlab.com/debdistutils/guix/container:latest sh-5.1# exit jas@kaka:~/src/guix-container$ Presumably because of a missing '--entry-point=/bin/sh' when building the images using 'guix pack'. So let's add it! Yes this now works: jas@kaka:~/src/guix-container$ podman run -it --rm registry.gitlab.com/debdistutils/guix/container:latest2 sh-5.1# exit jas@kaka:~/src/guix-container$ podman run --entrypoint /bin/sh -it --rm registry.gitlab.com/debdistutils/guix/container:latest2 sh-5.1# exit jas@kaka:~/src/guix-container$ However this breaks GitLab CI/CD usage: image: $CI_REGISTRY_IMAGE:latest2 https://gitlab.com/debdistutils/guix/container/-/jobs/8713593164 Ouch, that is the primary use-case we want to support! So until someone figures this one out, I've opted that the default images require --entrypoint when invoked local on laptops with podman but work without any configuration from GitLab shared runners and normal .gitlab-ci.yml usage. /Simon
