How do I force Docker for a clean build of an image

Question

I’m rebuilding a Docker image, but it keeps using cached layers from the previous build. As a result, updates or new configurations are not reflected. I want Docker to ignore the cache and rebuild everything from scratch.

What command or option should I use to force a clean build?

Thanks in advance!

Answer 1

You can try the following step:

You have an option i.e.;  --no-cache option:

docker build --no-cache -t u12_core -f u12_core .

In older versions of Docker you needed to pass --no-cache=true, but this is no longer the case.

I hope the above information will be helpful for you.

Answer 2

You could try this inorder to clean up the build cache:

docker builder prune --filter type=exec.cachemount

This command would delete the cache mount. 

Then you could try building the image.
