[BUG] actionable error message after buildkit endpoint checks are exhausted #977
Description
Version of copa
copa version 0.10.0
Expected Behavior
Copa runs without containerd snapshotter.
Actual Behavior
I am running Copa on a MacOS Sequoia 15.3.2 with Docker Desktop Version 4.39.0 (184744) installed. Trying to run Copa with the default configuration of Docker Desktop results in the following error:
$ copa patch -i alpine:3.20.0 -t 3.20.0-patched
Error: could not use docker driver: failed to solve: requested experimental feature mergeop has been disabled on the build server: only enabled with containerd image store backend
requested experimental feature diffop has been disabled on the build server: only enabled with containerd image store backend
missing required buildkit functionality
could not use buildx driver: listing workers for Build: failed to list workers: Unavailable: connection error: desc = "transport: Error while dialing: read /Users/toddysm/.docker/buildx/instances: is a directory"
could not use buildkitd driver: %!w(<nil>)
Configuring Docker Desktop with the containerd snapshotter (https://docs.docker.com/engine/storage/containerd/) fixes the issue. Reverting back the configuration reproduces the issue.
