Create a Docker container based on a repo from RDO Trunk

gistfile1.txt

1. Create a Dockerfile with the following contents:

FROM centos:7
LABEL maintainer=jpena name=DLRN-current
# Install Apache and rsync
RUN yum -y install httpd rsync && yum clean all
# Sync trunk.rdo contents
RUN rsync -avL trunk.rdoproject.org::centos7/current/ /var/www/html/repos
# Run command when container is started
CMD /usr/sbin/httpd $OPTIONS -DFOREGROUND

2. Build the container image

$ docker build -t dlrn/current:$(date --utc "+%Y%m%d%H%M%S") .

Using a date for the tag allows you to create multiple builds.

Note: rsync access is not enabled for all, we need to allow it case by case.

3. Run it

$ docker run -p 8080:80 dlrn/current:20170517104848 

4. Now, you can create a .repo file pointing to http://localhost:8080/repos, which will use the RDO Trunk repo you synced.
