Multi-stage docker build support (using --target in build) does not appear to work

Jason Ryan December 21, 2021
docker build --target build_stage_target -t build_name . 


Running the above command in my pipelines does not produce the desired results. The --target flag is apparently ignored, and the build runs all stages before and after the specified stage.


Is this indeed not supported or could I be doing something wrong?

This is really an issue 😭
@Jason Ryandid you solve the problem?

Jason Ryan March 15, 2023

Sadly I did not :(

Ok, thanks!

Hi @Jason Ryan 👋

In our team we found the answer. This is not a Bitbucket issue, but the Docker itself. BuildKit fixes this bug in multi-stage builds in the legacy docker build engine.

So, just enable the BuildKit by inserting the line


before the docker build command and the image will be built with the specified target.

So simple, bro))
