Docker runner chroot does not work within gitlab-ci-docker-runner -


i automating process of creating sd-image embedded platform. using gitlab ci in particular docker runner. works on system locally, when runs in gitlab ci, there strange errors.

here process:

  • i start docker container, runs build.sh.
  • build.sh chroot on mounted image , runs provision.sh.

details

i first run docker this:

docker run --rm -it --privileged=true -v `pwd`:"/wd" -w="/wd" ubuntu:xenial-20170710 /bin/bash build.sh

the file build.sh looks this:

apt-get update apt-get install qemu-user-static pixz -y pixz -d ubuntu-16.04.2-minimal-odroid-xu4-20170516.img.xz ubuntu-    16.04.2-minimal-odroid-xu4-20170516.img md5sum -c ubuntu-16.04.2-minimal-odroid-xu4-20170516.img.md5 limits=$(sfdisk -l --bytes ubuntu-16.04.2-minimal-odroid-xu4-20170516.img | tail -n 1) loopdev=$(losetup -f --show -o $((512 * $(awk '{print $2}' <<< "$limits"))) --sizelimit $(awk '{print $5}' <<< "$limits") ubuntu-16.04.2-minimal-odroid-xu4-20170516.img)  mkdir /mnt/rna mount $loopdev /mnt/rna mount -t proc proc /mnt/rna/proc/ mount -t sysfs sys /mnt/rna/sys/ mount -o bind /dev /mnt/rna/dev/ echo 'nameserver 8.8.4.4' >> /mnt/rna/etc/resolv.conf  cp $(which qemu-arm-static) /mnt/rna/usr/bin cp provision.sh /mnt/rna/root chroot /mnt/rna qemu-arm-static /bin/bash -l /root/provision.sh  mv ubuntu-16.04.2-minimal-odroid-xu4-20170516.img rna.img pixz rna.img rna.img.xz  losetup -d $loopdev

in case interested in image, can found here: https://odroid.in/ubuntu_16.04lts/ubuntu-16.04.2-minimal-odroid-xu4-20170516.img.xz

the provision.sh following:

pwd env ls -la  apt-get update apt-get install tmux -y

problem

locally, works fine , apt-get installs run inside image.

the .gitlab-ci.yml looks follows:

image: ubuntu:xenial-20170710  build:   tags:     - privileged   artifacts:     expire_in: "1h"     paths:       - rna.img.xz   script:     - ./build.sh

but when run gitlab ci, following messages (the start md5sum check inside build.sh:

ubuntu-16.04.2-minimal-odroid-xu4-20170516.img: ok ubuntu-16.04.2-minimal-odroid-xu4-20170516.img.xz: ok /root/.profile: line 9: /usr/bin/mesg: no such file or directory / /root/provision.sh: line 2: /usr/bin/env: no such file or directory /root/provision.sh: line 3: /bin/ls: no such file or directory /root/provision.sh: line 5: /usr/bin/apt-get: no such file or directory /root/provision.sh: line 6: /usr/bin/apt-get: no such file or directory

the docker-runner runs in privileged mode ensure chroot , mount working.

i got working now. seems has been caching problem within gitlab-runner.
