Install ginatra by git clone and not gem install

It seems that the HTW occasionally restarts the server. When the day the revealjs, nginx and postgres-service do not restart with the server. Probably the systemd unit-file needs some tweaking.

Problem
Currently everything is an app. So the app-folder gets bloated over time and the jenkins ui is hard to navigate, too. There is no feasible way to distinguish from the os perspective which app or jenkins job relates to which student.

Solution
One solution would be to introduce a student model that represents the credentials on the aris server, e.g. git-ssh access, file permissions and could be used to organize the files into student directories:

• /var/apps/s0001/ which contains alls the students apps
• /var/lib/jenkins/jobs/s0001/ which contains all the students jobs

As a result I can also create a finer grained ansible aris-cron which only checks for the necessary changes. E.g. a change on the app does not imply checking the os-users ssh configuration.

• aris-user-cron
• aris-app-cron
• aris-jenkins-cron

Migration
I need to migrate the current system since many things may be leaking outside:

• The git-ssh access leaks the app-name and needs to be updated by each student
• Also I would remove all app folders including the students code. Therefore each student would have to push his code again to the new bare repository

The welcome/default page contains actually much more than the slides, e.g:

• exercises
• setup hints
• timetable (tbd)
• and ofc slides

I think the name portal.htw-webtech.com or something similar would be more approriate than slides.htw-webtech.com

Problem
Right now the jenkins service is configured via systemd unit file. Access to ruby is configured via Environment-Declaration. This seems like a brittle solution when upgrading ruby versions.

Solution

Problem
Wenn Ansible bei einem Task abstuerzt kuemmert es sich nicht mehr darum hinter sich aufzuraeumen. Bspw. die processing.yml zu entfernen. Das sieht dann fuer den crojob so aus, als wuerde der Task noch laufen.

Solution
Einen wrapper fuer aris/jenkins-cronjobs bauen der sich um das aufraeumen kuemmert.
