failed to solve with frontend dockerfile.v0: failed to create LLB definition: the Dockerfile cannot be empty

What does that last sentence mean? And how do I solve it? Also it says the build is finished does that this worked??? Let me know if I need to provide anymore details. Thanks!

Docker throws error failed to solve with frontend dockerfile.v0: failed to build LLB due to a number of reasons –

  • Using Virtual Private Network (VPN)
  • Some file might not exist but used in Dockerfile
  • Wrong file permissions. This could happen due to copying of files from windows directory to Docker linux container. Check for -rwxr-xr-x permission on all files.
  • Wrong case or filename of Dockerfile. It should be capital D and then all lowercase without any space.
  • Extension in Dockerfile. Some text editors add .txt to the file. Check if it is in your Dockerfile. There should not be any extension.
  • Some folder you are copying in Dockerfile but prevented through .dockerignore.
  • Some invalid character in docker build command like NO-BREAK-SPACE, Hair Space, EM Space etc. These are undetectable and can lead to invalid command
  • Typo in Dockerfile content like FROM apline.

Solution with Code Example

1. If you are using VPN, set proxy manually. Go to settings -> Resources -> proxies -> select manual proxy configuration.

2. Make sure that all the files should exists that you are using in your Dockerfile.

3. If you are copying files from windows to linux directory, then check the file permission. Sometimes they become ---- ---- ----. Use chmod and chown commands to change file permission.

4. Set Buildkit=0 to get enhanced errors for better debugging –

DOCKER_BUILDKIT=0 docker build ...

Or, you can set it using command line as export variable. If you are using Linux or Mac, you can use –

export DOCKER_BUILDKIT=0 export COMPOSE_DOCKER_CLI_BUILD=0

On windows docker desktop, Go to Settings -> Docker Engine. You will find a JSON. Change buildkit to false. Check out this image –

5. Dockerfile should not have any extension. You should enable extensions in file explorer and check if Dockerfile is with or without extension. Also, make sure that it is name correctly – Dockerfile.

6. You may also try restarting the docker desktop and command line. This resolves any broken run time bug.
