WE NEED TO DEFINE WORKFLOWS AND PROCEDURES WELL... Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 9. What can we do...? Software Factory in a Box! - a Virtual Machine with an OSS OS (Ubuntu Server 10.04 LTS) - built on OSS tools - implementing a software factory - for Maven/Java projects (mostly...) - we can experiment best practices with Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 10. What’s inside the Software Factory in a Box... The VM contents: - redmine (issue tracker & wiki) - subversion edge (scm + management tools) - jenkins (continuous integration) - artifactory (maven repository) - sonar (source code reporting) with the same identity across all systems provided by OpenLDAP (directory server) Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 11. Redmine http://www.redmine.org/ - wiki with markdown syntax - multi-project issue tracker with customizable workflow - milestone planning - integration with subversion and many more SCM... - notifications - GPLv3 license, built on Ruby and Rails Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011

Jenkins http://jenkins-ci.org/ - possibly the most widely used OSS continuous integration server - can ran as job scripts, ant/maven builds triggered on specific conditions - integration with subversion and many more SCM... - extensible via plugins with rich directory: - sonar plugin - promotion plugin - artifactory plugin - MIT licensed, built on Java Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 13.

- 14. Artifactory http://www.jfrog.com/products.php - a generic repository manager can host artifacts and dependencies - built for Maven but supporting also Ivy and Gradle - remote REST APIs supports publishing via POST of generic files - cache for external repositories, pre-configured with most used ones: (Maven Central, Codehaus, JBoss, Spring...) - LDAP support - LGPLv3 licensed, built on Java Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011

OpenLDAP + web management provided by Zentyal http://www.zentyal.org/ - web interface for Small Business Server - based on Ubuntu Server 10.04 LTS - all the configuration is on OpenLDAP http://www.openldap.org/ - we’re using just its user and group module - can sync to external LDAP server even Active Directory with password sync! - provides self-service change password web Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 17. Let’s experiment with some best practices... ...and check if they’re fit for us! Let’s see some possible examples... - use a wiki as project knowledge base - slice requirement documents in issues and track them - avoid “downloading the internet” with maven - build project with dedicated maven repository - one repository per project with standard trunk/tags/branches layout on subversion - promote and release projects from the CI server - share common project properties using a parent POM - publish a documentation site for a project with maven - monitor health state of source code through static analysis - create our custom maven archetypes and publish them on artifactory Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 18. What’s next... We can move our Software Factory in a Box VM in the virtualized infrastructure of our company datacenter! Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 19. What’s next too... If we don’t want to host some of these tools... many of them offer a cloud service version... - DEV@cloud by CloudBees for Jenkins - Artifactory Online by JFrog - many more for Redmine and Subversion ...but don’t forget to manage identityacross all services! Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
- 20. Or yet what’s next again... We can switch from Subversion to a more advanced SCM... ..like Git for example! And use instead of Subversion Edge as a distribution of Git with web management for user, repositories and permissions available as service and packaged... http://www.gitenterprise.com Marcello Teodori - marcello.teodori@gmail.com – JUG Milano sabato 5 marzo 2011
