When I rebuild my Docker image, it reuses cached layers, but I want to ensure a clean build, especially since some files like Aerospike aren’t appearing in the container.
What’s the right way to do a docker clear cache and force Docker to ignore the existing build cache completely?
Yeah, I’ve had this issue too, especially when adding files like binaries or configs that don’t seem to make it into the image.
The easiest fix is to use the --no-cache flag:
bash
Copy
Edit
docker build --no-cache -t my-image.
That tells Docker to skip all cached layers and rebuild each step.
It’s a lifesaver when you’re not sure which step went wrong.
@Ariyaskumar Been there! Sometimes Docker just gets too smart for its own good. I use --no-cache, but if I want to really start fresh, I also remove the old image first:
bash
Copy
Edit
docker image rm my-image
docker build --no-cache -t my-image .
That way you’re sure there’s no leftover image data hanging around messing things up.
Helps a lot with tricky setups like Aerospike or Redis config files.
I usually pass --no-cache during build when things start acting weird:
bash
Copy
Edit
docker build --no-cache -t clean-build .
But I also learned that if you’re copying a file into the image and it’s not showing up, make sure Docker isn’t skipping that COPY step because the source file didn’t change.
Even tiny edits or renaming the file can help force the rebuild of that layer.
