Hi @developer-guy , thanks for reaching out!

FATA[0002] no image found in manifest list for architecture amd64, OS darwin

Are you executing skopeo on Mac OS? As Fedora only supports Linux, the error looks correct to me as multi-arch manifests will be selected based on the host's platform.

You can use the --raw flag to list the platform-specific manifests and use the digest notation to inspect the manifest you're looking for, e.g.:

$ skopeo inspect --raw docker://docker.io/fedora:rawhide

thank you for your quick response, it works @vrothberg 👍

Maybe more practically, skopeo --override-os linux … will work with the Linux version of the image, without otherwise affecting the semantics; e.g. skopeo --override-os linux copy … copies the Linux image just like running skopeo on Linux would..

[cmoulliard]

since latest version of skopeo, adding the parameter --raw don't resolve the problem anymore on MacOS

VERSION:
   0.1.37-dev commit: b1377413855cfe601d83c8c653ce6b629e41fb98

 ./skopeo inspect --raw --creds username:pwd docker://registry.redhat.io/openjdk/openjdk-8-rhel8

And using --override-os generates a very strange result

NAME:
   skopeo inspect - Inspect image IMAGE-NAME

USAGE:
   skopeo inspect [command options] IMAGE-NAME

DESCRIPTION:

  Return low-level information about "IMAGE-NAME" in a registry/transport

  Supported transports:
  containers-storage, dir, docker, docker-archive, docker-daemon, oci, oci-archive, ostree, tarball

  See skopeo(1) section "IMAGE NAMES" for the expected format

OPTIONS:
   --raw                        output raw manifest or configuration
   --config                     output configuration
   --authfile value             path of the authentication file. Default is ${XDG_RUNTIME_DIR}/containers/auth.json
   --creds USERNAME[:PASSWORD]  Use USERNAME[:PASSWORD] for accessing the registry
   --cert-dir PATH              use certificates at PATH (*.crt, *.cert, *.key) to connect to the registry or daemon
   --tls-verify value           require HTTPS and verify certificates when talking to the container registry or daemon (defaults to true)
   --shared-blob-dir DIRECTORY  DIRECTORY to use to share blobs across OCI repositories
   --daemon-host HOST           use docker daemon host at HOST (docker-daemon: only)
   --no-creds                   Access the registry anonymously

Hum, did it ever work on macOS for Linux Images? AFAICS --raw never turned off parsing of the image and the like, it only affected the output. (I realize that a comment above recommends --raw, so I might have missed something.)

And using --override-os generates a very strange result

./skopeo inspect --override-os linux --creds user:pwd docker://registry.redhat.io/openjdk/openjdk-8-rhel8

--override-os is a global option, so, skopeo --override-os linux inspect ….

[cmoulliard]

global option

Great to know. That works ! Many thanks

On mac M1
