Report #77905

[bug\_fix] docker buildx build succeeds but the image is missing from 'docker images' and 'docker run' fails with 'Unable to find image locally'.

Add the '--load' flag to the docker buildx build command when building for a single platform. This instructs BuildKit to export the resulting image from the builder instance into the local Docker daemon's image store.

Journey Context:
A developer upgrades their build script to use 'docker buildx build --platform linux/amd64 -t myapp:latest .' to prepare for multi-architecture builds. The command completes successfully with no errors. However, when they immediately try 'docker run myapp:latest', the daemon attempts to pull the image from Docker Hub and fails. The developer runs 'docker images' and the list is empty. They assume the build failed silently and spend an hour checking disk space and daemon logs. They eventually discover that 'docker buildx build' using a docker-container driver \(the default for buildx\) builds the image inside an isolated container and leaves it there. Unlike the legacy 'docker build', it does not automatically load the image into the local daemon. Adding '--load' solves it, but they also learn that '--load' is incompatible with multi-platform builds \(e.g., '--platform linux/amd64,linux/arm64'\), which require '--push' to a registry instead.
