Docker: ERROR [internal] load metadata for docker.io

Question

On Windows 10, Docker Desktop (Docker Engine v20.10.17, WSL enabled and running properly) fails to docker build an image (that, btw, works properly on Debian 11) throwing following error:

docker build -t <image-name> .
[+] Building 2.3s (3/3) FINISHED
 => [internal] load build definition from Dockerfile                                0.1s

A similar case was answered here, although the solution doesn't apply in my case. Searching the web yielded several similar (but not identical) cases with different solutions (including a reinstall), which all failed to solve this.

Answer 1

In the end I found a (or the) solution in the Docker forum: in Docker Desktop, navigate to Settings > Docker Engine, change buildkit to false in the Docker daemon configuration file and then click "Apply & Restart".

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "features": {
    "buildkit": false
  }
}

I have a similar error: ERROR [internal] load metadata for docker.io/library/ubuntu:latest – Winch

Works but loses all the buildkit avantages. – Nucleolar

NOTE: daemon config file at C:\Users\<USER>\.docker\daemon.json – Interested

Solution
sudo rm ~/.docker/config.json
Rerun restart

this gets the job done, things go back to normal with docker compose working again. – Yeo

This works for me, running on MacBook Pro M3 Max – Tipster

Hey, your answer seems to be more a comment. You might want to adjust accordingly... – Kerosene

@Kerosene Thank you for the reminder. I have already added the code. – Draconic

Works for me though – Photomap

Answer 4

In Linux, the solution above didn't work for me but the following did:

docker pull <image-name>

Answer 5

docker pull [image-name] docker build [...]

On windows, I pulled the image first, then ran the build.

Answer 6

This can sometimes happen if you have a momentary network blip. Sometimes the solution is just to run the Docker command again.
