cli/command/image: remove special handling for plugin errors on pull - #6374
Merged
Conversation
This special handling was added in [moby@9b6dcc8], and later updated in [moby@c127d96], but it fully depended on string-matching, which is brittle. Testing the original ticket that lead to this handling, it looks like the string matching no longer works, and the daemon error is returned as-is: With graphdrivers: docker pull tiborvass/no-remove Using default tag: latest Error response from daemon: Encountered remote "application/vnd.docker.plugin.v0+json"(unknown) when fetching With containerd snapshotters enabled: docker pull tiborvass/no-remove Using default tag: latest latest: Pulling from tiborvass/no-remove cf635291f7c9: Download complete failed to unpack image on snapshotter overlayfs: mismatched image rootfs and manifest layers The error-message for containerd can probably be improved, but as the special handling in the CLI no longer works, we can remove it. [moby@9b6dcc8]: moby/moby@9b6dcc8 [moby@c127d96]: moby/moby@c127d96 Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
