Fuse Integration Services Demo

This demo is based on quickstart archetype project and the aim is to explain how to reproduce a small demo on each of the two build workflos available for now in Fuse Integration Services:

• Build the image outside Openshift then push it
• Push the code then let Openshift build the image Fuse Integration Services is a collection of tools shipped by Red Hat to develop and run JBoss Fuse application on Openshift.

What you need

To be able to demo the 2 scenarios an Openshift environment is needed, one of the easies way to achive that is by using a virtual machine provisioned via vagrant; there are many option to do so and many kind of images (demobuilder, fabric8v2 etc.) here are some caveats for the CDK environment by Red Hat:

• Be sure to install virtualbox and vagrantand be able to run vagrant without root access (if on linux)
• Download virtualbox vm image and cdkv2 from https://access.redhat.com/downloads/content/293/ver=2/rhel---7/2.0.0/x86_64/product-software
• Unzip cdk-2.0.0-beta4.zip and go to cdk/components/rhel/rhel-ose
• Modify Vagrant file replacing OPTINS variable with:
  • OPTIONS='--selinux-enabled -H tcp://0.0.0.0:2376 -H unix:///var/run/docker.sock --tlscacert=/etc/docker/ca.pem --tlscert=/etc/docker/server-cert.pem --tlskey=/etc/docker/server-key.pem --tlsverify --storage-opt dm.no_warn_on_loop_devices=true'
  • Set memory and cpu to something reasonable for your hardware a minimum would be v.memory = 4096 and v.cpus = 2
  • Configure landrush plugin for DNS: config.landrush.enabled = true, config.landrush.tld = 'cdk.vm', config.landrush.host 'cdk.vm', "#{PUBLIC_ADDRESS}"
• vagrant plugin install vagrant-registration vagrant-service-manager landrush
• vagrant box add --name cdkv2 path/to/rhel-cdk-kubernetes-7.2-19.x86_64.vagrant-virtualbox.box
• Configure dnsmasq:
  • Be sure to turn off libvirt and kill dnsmasq
  • configure dnsmasd by creating ``/etc/dnsmasq.d/vagrant-landrushwith this contentserver=/.vm/127.0.0.1#10053`
  • change your /etc/resolv.conf to contain as first line nameserver 127.0.0.1
  • more info and full explanation here: http://nts.strzibny.name/dns-for-your-vagrant-needs-with-landrush-libvirt-and-dnsmasq/
• vagrant up (fill in the required username and password with a valid RH account)

To run command as system:admin in cdk once you have sshed in to it with vagrant ssh you can do sudo oc get nodes --config=/var/lib/origin/openshift.local.config/master/openshift-master.kubeconfig

Build then push demo

To showcase this scenario you can follow these steps:

• Get an example project by cloning this one git clone https://github.com/valdar/fis-example or by using a maven artifact mvn archetype:generate -DarchetypeCatalog=https://repo.fusesource.com/nexus/content/groups/public/io/fabric8/archetypes/archetypes-catalog/2.2.0.redhat-079/archetypes-catalog-2.2.0.redhat-079-archetype-catalog.xml
• export KUBERNETES_MASTER=https://10.1.2.2:8443
• export KUBERNETES_DOMAIN=cdk.vm
• log in to Openshift cluster from your machine oc login test-admin
• create a new project (namespace), oc new-project buildpush
• import s2i images in the project: oc create -n buildpush -f https://raw.githubusercontent.com/jboss-fuse/application-templates/master/fis-image-streams.json
• build the code, build doker image put it in Openshift docker registry, generate .json Openshift configuration files, push (apply) them to Openshift: mvn -Pf8-local-deploy

Be sure to have these repo configured in your maven setting.xml:

Push then build demo

To showcase this scenario you can follow these steps:

• export KUBERNETES_MASTER=https://10.1.2.2:8443
• export KUBERNETES_DOMAIN=cdk.vm
• log in to Openshift cluster from your machine oc login test-admin
• create a new project (namespace), oc new-project pushbuild
• import s2i images in the project: oc create -n pushbuild -f https://raw.githubusercontent.com/jboss-fuse/application-templates/master/fis-image-streams.json
• import this example application template in the project: oc create -n pushbuild -f https://raw.githubusercontent.com/valdar/fis-example/master/quickstart-template.json
• use the just created template to instantiate an application pointing it to the git sourcecode repo https://github.com/valdar/fis-example

Now Openshift should grab the code for you, build the docker image containing your code and spin the application up.
