2 What is OpenShift? Red Hat s free platform as a service for applications in the cloud. 2

3 Flavors Open Source Project origin Public Cloud Service Onpremise or Private Cloud Software 3

4 Terminology Broker Management host, orchestration of Nodes Node Compute host containing Gears Gear Allocation of fixed memory, compute, and storage resources for running applications Cartridge A technology/framework (PHP, Perl, Java/JEE, Ruby, Python, MySQL, etc.) to build applications Application Instantiation of a Cartridge Client Tools CLI, Eclipse, Web Console for creating and managing applications 4

5 5 Architecture

6 History Cartridge V1.0 Opensource, but not easy to implement or customize Overly large number of files/scripts Blurred Node vs Cartridge responsibility (e.g. root access required by Cartridge) Each version required a new Cartridge Difficult to maintain APIs not versioned 6

7 History Cartridge V2.0 Eased implementation, customization, and maintenance Greatly reduced number of files/scripts Well-defined Cartridge vs Node responsibility (e.g. root access not required by Cartridge) Well-defined and versioned API Multiple versions supported in single Cartridge Documentation: 7

8 Requirements The OpenShift Cartridge API consists of: Executable files stdout/stderr Environment variables You can use any language but we find bash the fastest Bash SDK provided, other languages planned The software you are packaging either needs to be on the system or included in your cartridge 8

9 Minimal Cartridge +- bin +- setup +- control +- env +- metadata +- manifest.yml *Assumes packaged software already installed on system *Most cartridges will have more files 9

10 metadata/manifest.yml Elements Name Version Cartridge-Version Cartridge-Vendor Endpoints *Other elements for defining features of your cartridge and it's packaged software 10

11 Downloadable Cartridges Implement your own cartridges (e.g. as github project) No need for RPMs, installation ZIP, tarball also supported rhc app create app-name url-to-raw-manifest End of When will OpenShift support??? Infinispan, ActiveMQ, Torquebox, Ceylon, CapeDwarf, etc. Vertx, RHQ, etc. coming! 11

12 Middleware Projects ActiveMQ ActiveMQ is the most popular and powerful open source messaging and Integration Patterns server. Infinispan Infinispan is an extremely scalable, highly available key/value NoSQL datastore and distributed data grid platform Torquebox TorqueBox is a new kind of Ruby application platform that supports popular technologies such as Ruby on Rails and Sinatra, while extending the footprint of Ruby applications to include built-in support for services such as messaging, scheduling, caching, and daemons. 12

13 Full Disclosure Development Environment EC2 m3.xlarge Medium Gears SSH Tunnel for JON Access Code Changes Required JGroups (released, upstream) ActiveMQ, Vertx Hazelcast Spring, Apache Commons 13

14 New Downloadable Cartridges Infinispan & ActiveMQ Embedded DEMO Servlet ActiveMQ Infinispan ActiveMQ Framework DEMO Torquebox Framework DEMO 14

15 Management & Monitoring Ops/SysAdmin Use-Case Install JON/RHQ Agent on Node Node Scope Available now! DEMO Developer Use-Case RHQ/JON Cartridge Embed Agent into other applications (think Jenkins) Embedded/Account Scope RHQ Cartridge Coming Soon! 15
