Java DSL
public class OrderProcessorRouteBuilder extends RouteBuilder {
@Override
public void configure() throws Exception {
from(“activemq:orders”)
.choice()
.when(header(“customer-rating”).isEqualTo(“gold”))
.to(“ibmmq:topic:specialCustomer”)
.otherwise()
.to(“ftp://user@host/orders/regularCustomers”)
.end()
.log(“received new order ${body.orderId}”)
.to(“ibatis:storeOrder?statementType=Insert”);
}
}

15. RED HAT | ADD NAME15
Spring XML DSL
<route id=“processOrders”>
<from uri=“activemq:orders”/>
<choice>
<when>
<simple>${header.customer-rating} == ‘gold’</simple>
<to uri=“ibmmq:topic:specialCustomer”>
</when>
<otherwise>
<to uri=“ftp://user@host/orders/regularCustomers” />
</otherwise>
</choice>
<log message=“received new order ${body.orderId}”/>
<to uri=“ibatis:storeOrder?statementType=Insert”/>
</route>

29. RED HAT | ADD NAME29
Current issues with deployments
• Installation
• SSH, download, unpack, install, permissions, ENV var
• Configuration
• Container, individual apps/services, brokers, security
• Upgrading
• Install, configure, rollback
• Introspection
• Big picture statistics (JVM/OS memory usage, CPU)
• JMX (jconsole, visualVM)

30. RED HAT | ADD NAME30
Clients aware of Topology
• Brokers
• failover:(tcp://host1:port1,tcp://host2:port2)
• Camel endpoints
• from(“jetty:http://22.33.44.55:8080/endpoint”)
• to(“http4://11.22.33.44:9000/endpoint”)
• Web service endpoints
• Access a specific endpoint: http://22.33.44.55:9091/endpoint

31. RED HAT | ADD NAME31
Current best practices
• Use templates for configuration w/ template engine
• Puppet/Chef and/or Capistrano/Ansible
• Store configuration (templates + values) in SCM
• Separate configuration from binary deployments
• Verifiable build and release process

32. RED HAT | ADD NAME32
• Simplifies deployments
• Provides management tools for centralized
configuration
• Visualize your middleware with HawtIO
• Polycontainer
• Blurs the line of PaaS
http://fabric8.io

33. RED HAT | ADD NAME33
• Provides cluster capabilities, coordination
• Service discovery, load balancing, failover
• Deploy to cloud (IaaS, PaaS)
• Supported as JBoss Fuse (managed)
• fabric8 1.0 is in Fuse 6.1
• 1.1 about to be released
• RC1 released 6/10
http://fabric8.io

34. RED HAT | ADD NAME34
fabric8 1.1 release
• Java Container
• Tomcat, TomEE, Jetty
• Spring Boot
• fabric:watch * with various containers
• Profile import/export
• fabric8 maven plugin enhancements

Core concepts
• Fabric registry
• Holds all configuration data
• Runtime registry for looking up distributed services
• Profile
• Describes the container set up
• Features, Bundles, ConfigAdmin PIDs, system properties
• Hierarchical structure
• Container versioning
• Agent
• Runs on each container
• Communicates with registry to make sure container provisioned
correctly

37. RED HAT | ADD NAME37
How’s fabric8 different than Puppet/Chef?
• Middleware centric
• Container agnostic
• Deep knowledge about the running processes
• Consistent configuration
• Visualizations
• Versioning built in, upgrades, rollbacks, selective
upgrade, etc
• Use puppet/chef to provision your machines, use
fabric8 to provision and manage your middleware/
apps

43. Continuous Delivery

44. RED HAT | ADD NAME44
Continuous Delivery
• Builds on continuous integration
• Establish a concrete pipeline to production
• Build/Test/Release often!
• Bottlenecks?
• Involves Dev and Ops to be successful
• Every build is a “release candidate”

45. RED HAT | ADD NAME45
Automate everything!
• Developers
• Unit tests
• Integration tests
• Builds
• Deployments in dev
• Operations
• VMs
• Provisioning software
• Deployments in QA/UAT/PROD

46. RED HAT | ADD NAME46
Tools for a CD pipeline
• Puppet/Chef to provision VMs
• Git for SCM
• Gerrit/Gitlab for code reviews
• Maven
• Jenkins + plugins
• and of course… Fabric8!
• What’s this Docker thingy?

47. RED HAT | ADD NAME47
Fabric8 maven plugin
• fabric8:deploy
• fabric8:zip
• fabric8:aggregate-zip
• fabric8:branch
• fabric8:script (for karaf only)
• http://fabric8.io/gitbook/mavenPlugin.html

48. RED HAT | ADD NAME48
Sample flow
• Check your code in
• Gerrit for code reviews
• Jenkins for build + CD pipeline
• Use fabric8:zip to deploy profiles to Maven repo
• Use fabric8:branch to automate deploying multiple
profiles to QA/UAT/PROD
• Can use profile-import to manually import zips
• Build the binary once!
