Currently, the CI system may pick the wrong (non-native) architecture due to the missing prefix.
For example, assuming the CI_IMAGE_NAME_TAG is debian:bookworm
and the user has previously pulled an s390x image:
0$ podman run --rm 'docker.io/s390x/debian:bookworm' dpkg --print-architecture
1exec /usr/bin/dpkg: exec format error
Now, debian:bookworm
will refer to the same image:
0$ podman run --rm 'debian:bookworm' dpkg --print-architecture
1exec /usr/bin/dpkg: exec format error
However, docker.io/debian:bookworm
works fine:
0 $ podman run --rm 'docker.io/debian:bookworm' dpkg --print-architecture
