docker build this image https://github.com/lineageos4microg/docker-lineage-cicd

create a folder somewhere where all your lineageos stuff goes.
Then run the container as follows (you might need to create those other directories first):
docker run -e "SIGN_BUILDS=true" -e "SIGNATURE_SPOOFING=restricted" -e "BRANCH_NAME=lineage-16.0" -e "DEVICE_LIST=pro1" -v "/mylocaldir/repo:/srv/src" -v "/mylocaldir/zips:/srv/zips" -v "/mylocaldir/logs:/srv/logs" -v "/mylocaldir/cache:/srv/ccache" -v "/mylocaldir/local_manifests:/srv/local_manifests" -v "/mylocaldir/keys:/srv/keys" lineageos4microg

Or you can have the container add additional useful prebuild software to the image.
add local_manifests/prebuilds.xml:

<?xml version="1.0" encoding="UTF-8"?>
