Description

Buiding an image from another image from an insecure registry results in error.

Just did a fresh install of docker in a new machine and configured the "insecure-registries" in /etc/docker/daemon.json.

Expected behaviour

That the image is built

Actual behaviour

ERROR: failed to solve: my.registry:8082/image:latest: failed to resolve source metadata for my.registry:8082/image:latest: failed to do request: Head "https://my.registry:8082/image/manifests/8": remote error: tls: unrecognized name

Reproduce the issue with the shown Dockerfile, docker build command, and /etc/docker/daemon.json configuration, comparing it with the working docker pull. Trace how the default builder resolves the FROM image and whether the insecure registry setting is honored; done means the build uses the configured registry protocol and completes successfully.
