I'm trying to build a docker image for a software using docker build -t cytools .

Here is the output that I'm confused about:

[+] Building 0.0s (1/2)                                                         
 => [internal] load build definition from Dockerfile                       0.0s
 => => transferring dockerfile: 2B                                         0.0s
failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount346931491/Dockerfile: no such file or directory

Does anyone know what this means? I am new to all this, so sorry if I didn't use the correct terminology or give the full picture!

  • Hello! Can you update your question with a few more details please? For example can you show the dockerfile you are using? Mar 26 '21 at 16:39
  • From the command prompt, please perform an ls or dir in that same directory to show that Dockerfile exists, has a capital D and no extension.

  • Thank you, I think your comments resolved the issue! The dockerfile wasn't in the same directory.

Looks like the Dockerfile is not in the path, '.' means the current directory you are in.
