The nugulinux/buildenv docker image contains a sbuild.sh script that makes it easier the build. The script is a simple sbuild wrapper that automatically puts --chroot, --host and -j{n} options for the image.

$ git clone {url}/myrepo
$ docker run -t --rm --privileged -v $PWD:$PWD -w $PWD/myrepo \
    -v /var/lib/schroot/chroots nugulinux/buildenv:focal_x64 sbuild.sh
$ ls
myrepo/
myrepo_amd64.deb

You can use the parameters used in the sbuild command in sbuild.sh as well.

$ git clone {url}/myrepo
$ docker run -t --rm --privileged -v $PWD:$PWD -w $PWD/myrepo \
    -v /var/lib/schroot/chroots nugulinux/buildenv:focal_x64 \
    sbuild.sh --extra-repository="deb [trusted=yes] http://ppa.launchpad.net/nugulinux/sdk/ubuntu focal main"

$ ls
myrepo/
myrepo_amd64.deb

The nugulinux/buildenv already has preconfigured images for arm64 and armhf. So simply specify the desired target in the tag of the docker image.

$ git clone {url}/myrepo
$ docker run -t --rm --privileged -v $PWD:$PWD -w $PWD/myrepo \
    -v /var/lib/schroot/chroots nugulinux/buildenv:bionic_armhf sbuild.sh
$ ls
myrepo/
myrepo_amd64.deb

You can create your own sbuild image using mk-sbuild tool and base image.
