ulimit argument has no effect on buildkit #1665
Description
Test case, Dockerfile:
FROM alpine
RUN ulimit -n > /tmp/ulimit.txt
Then I build this image with docker build --ulimit nofile=1024:1024 . -t test. After building, command docker run -it test cat /tmp/ulimit.txt prints 1073741816, which means infinity.
After turning off DOCKER_BUILDKIT, the command will print 1024 as expected. Issue may be connected with this problem, but it was marked as fixed 😠
