Docker based workflow for working on restraint - Beaker-devel - Fedora mailing-lists

15 Dec 2014


      In case you don't want a few additional packages on your system, here is a
script which will build a docker image installing all dependencies needed to run restraint's tests:
#!/bin/bash
# ./restraint.sh <image_name> <docker_base_image>
uid=`id -u`
user=`id -un`
cat <<EOF > Dockerfile
FROM $2
RUN yum -y install make glib2 glib2-devel glibc-devel libarchive-devel libsoup-devel gcc pkgconfig gettext libselinux-devel openssl-devel perl-XML-Parser selinux-policy-devel zlib-devel git git-daemon tar thttpd
RUN yum -y install emacs-nox
RUN useradd -u $uid $user
USER $uid
EOF
docker build -t $1 .
mv Dockerfile Dockerfile.$1
echo "$1 created. Entering: /home/$user"
docker run -v /home/$user:/home/$user -ti $1 bash
Assuming you have docker setup:
./restraint.sh fedora21_restraint fedora:21
Will build the docker image and also start the container:
Successfully built a8f0f98cb2f2
fedora21_restraint created. Entering: /home/asaha
Couple of things are worth noting:
1. It creates a user of the same username, uid and gid of the user you execute docker as
2. Assuming you are *not* using docker as root/sudo, this means, an user of the same uid/gid is created in
the container. Hence, since /home/$user is volume mounted, you should have r+w access to your host's
home directory (only if you turn off selinux or may be set it to permissive).
If you have a clone of restraint already in your home, you can directly start working on it, or just clone it 
and run "make check".
You will need http://gerrit.beaker-project.org/#/c/3869/ for all the tests to pass.
