Preview Repository

_PAGE WORK IN PROGRESS_

Overview

The aim of Preview is making available in a single point the updates of the middleware products as soon as they are released by the product teams. The same updates will also undego to the usual UMD verification and staged rollout processes, which requires several weeks to be completed; instead, through the Preview repository the resource centres administrators can avoid this wait and can apply the updates on their machines as soon as they are announced. Our plan is to release the Preview updates on a monthly basis, after having gathered the relevant information by the product teams.

Release process

The product teams usually announce a new version of their product by a GGUS ticket or email to URT team. In the announcement it is reported all the relevant information about the update: description of new features and bugfixes, installation and configuration details. The new packages are downloaded and signed, then it is created a new release of the Preview middleware uploading the new packages into the repository. After preparing the release notes, the Preview update is announced.

Starting point: Preview 1.0.0 series

The first Preview release is a mirror of the EMI3 repository, containing the Update 29 (11.11.2015) - v. 3.17.1-1 http://www.eu-emi.eu/releases/emi-3-monte-bianco/updates

All the 62 products making part of EMI-3 are included in this first release.

The operative systems supported are:

• Scientific Linux 6 /64 bit
• Debian squeeze 6 /64 bit

There is a single repository for all the components and for each OS.

Repository configuration

In order to configure the Preview repository, download it from the EGI Community Repository:

• SL6: http://repository.egi.eu/community/software/preview.repository/1.0/releases/repofiles/sl-6-x86_64.repo
• Debian squeeze: http://repository.egi.eu/community/software/preview.repository/1.0/releases/repofiles/debian-squeeze-amd64.list

In case of SL6, you should give this repository a higher priority than the EPEL one (install yum-priorities for this purpose). Please add also the protect option. For instance, the reopository file should look like the following one:

# EGI Applications Database (http://appdb.egi.eu/)
# EGI Community repository (http://repository.egi.eu/community/)
# POA ID:327
# Created: 2016-02-23 12:01:50 EEST
[preview.repository-sl-6-x86_64]
name=Repository for preview.repository (o/s: sl6 arch: x86_64)
baseurl=http://repository.egi.eu/community/software/preview.repository/1.0/releases/sl/6/x86_64/RPMS/
protect=1
enabled=1
# To use priorities you must have yum-priorities installed
priority=40
gpgcheck=0

Then you have to disable/comment/delete the EMI or UMD repositories (if installed) on your machines in order to avoid any mismatch.
