Dynamic Deployment with Marcel Offermans luminis

Introduction • Marcel Offermans • software architect Arnhem Apeldoorn De Steeg • Apache Felix and ACE • marcel.offermans@luminis.nl • Luminis • IT solutions from idea to implementation • experts in Java, OSGi, .NET, Agile/Scrum, Mobile luminis image © 2008 Google Earth

Status? • april 2009: proposal to the incubator mailing list • may 2009: started setting up project, IP clearance • june 2009: (almost) done with IP clearance :) luminis

Topology target provisioning management network server agent component repository luminis

Management Agent • manages life cycle of bundles BundleContext !"#$%"&'($)&%*+,-./'0 1/'&%"2&)$.$),-$/3 45&%!"#$%6++$,3)& 7&+&,8&%9:%;&'8$/3%9<= 62'$+%>??@ • controls package sharing policies PackageAdmin • controls relative starting/stopping order Digitally signed by OSGi OSGi Alliance DN: cn=OSGi Alliance, c=US Alliance Date: 2007.02.22 Signatur 14:45:47 + e Not 01'00' Verified Start Level Service • implements a security policy Conditional Permission Admin luminis

Management Agent • identification, uniquely identifies a target • discovery, provides mechanism to find server • scheduler, periodically triggers updates • deployment, downloads and installs updates • audit log, tracks all life cycle changes luminis

Deployment Admin • versioned set of artifacts • transactional install/update • fix packages provide deltas • signing makes them secure • extensible through resource processors luminis

Provisioning Server store deployment Store License Deployment Repository Repository Repository luminis

Deployment Repository Deployment Repository • has a collection of targets Target Component • with different versions for each target • with a set of components for each version targets versions components 1 Component A Component B 2 Component A Component B Component C Target A 3 Component A Component C Component D 4 Component C Component D luminis

Store and License Repository Store Repository License Repository Deployment Repository Component License + License Target = Target Component • store and license map components to targets • store groups components, license associates these with targets • these are all extensible objects • on every update, the consequences for the targets are calculated luminis

Metadata vs content • server repositories only store metadata • this avoids having IP in these repositories • it also allows integration with different component repositories (OBR, Maven, anything reachable via a URL) luminis

Scaling the server • repositories can be replicated • there is always one master (holding a copy that can be modified) Repository replication Repository master luminis

Manipulating data • client and server use a checkout / commit model with optimistic locking • client is responsible for “merging” if there are concurrent changes store version retrieve version Repository list versions luminis

The audit trail • management agent stores all life cycle related events in an audit log • this log gets synchronized back to the server server internet target Audit Audit Log Log 17:34 Checked for updates, none found 13:23 Target started 18:34 Bundle 23 stopped 23:20 13:24 Starting update from version 5 to 8 19:34 23:25 Target started 13:23 13:24 Bundle 37 updated 20:34 23:45 Starting update from version 5 to 8 13:24 13:25 Update to version 8 succeeded 21:34 02:22 Bundle 37 updated 13:24 14:25 Target stopped 05:22 Update to version 8 succeeded 13:25 14:25 Target stopped luminis

Summing it up • We’ve looked at dynamic deployment • the management agent on the target • the repositories on the server • ...which hopefully gives you a high level overview luminis
