docker-export's Issues

Better error message if platform is not available

I have experimented two kinds of failures which, at the first sight, were a bit puzzling to me:

is single platform and mismatches
v1 single platform and mismatches #3

I finally have understood what goes wrong, but I believe we could easier help the user to understand the problem.

I propose to add a line after the error(s) stating the requested platform and (if possible) the list of possible platforms provided. It could look like: Requested platform is "linux/arm/v7', but available paltform(s) is/are: "linux/arm/...", "linux/x86/..."

Implement -v|--version

There is not easy way (outside pip) to know the docker-export version.

Unable to export openzim/gutenberg (v1 single platform and mismatches)

ValueError: index.docker.io/openzim/gutenberg:latest is v1 single platform and mismatches

Improve the usage()

I believe the usage() would benefit of a one line per option.

It would be good as well to give "as example", the 2 or 3 most commons platforms.

Indicating that linux/arm/v7 is the default one would be useful as well.

Add Changelog

V0.3 is in preparation, it is time to add a Changelog file

image name and tag seem to vanish

Once I have exported a Docker image from a repository to a tarball, then I tried to import them with docker import.

It seems the images are imported, but tagging and naming have vanished:

$ docker images
REPOSITORY                            TAG                IMAGE ID       CREATED              SIZE

invalid character 'p' after top-level value

I have exported an image:

invalid character 'p' after top-level value

But if I try to load it, I get:

$ docker load < youtube.image.tar 
invalid character 'p' after top-level value
