Slides

This demo was presented at DevopsDday in the Velodrome, Marseilles' famous stadium. Here are the slides, in French. Or a similar English version.

Step-by-step

For a step-by-step walk-through, read this.

Pre-requisite

• Kubernetes or OpenShift cluster running (ex: minikube 0.27+ / minishift)
• Istio with Kiali installed
• Repo cloned locally (actually, only YML files are necessary)

Below instructions are given for OpenShift, but this is almost the same with standard Kubernetes. Just replace oc with kubectl, ignore oc expose, ignore the oc adm policy stuff.

OpenShift

For OpenShift users, you may have to grant extended permissions for Istio, logged as admin:

oc new-project mesh-arena
oc adm policy add-scc-to-user privileged -z default

Deploy all

Without runtimes metrics & tracing:

oc apply -f <(istioctl kube-inject -f full.yml)

With runtimes metrics:

oc apply -f <(istioctl kube-inject -f full-metrics.yml)

With tracing:

oc apply -f <(istioctl kube-inject -f full-tracing.yml)

With everything:

oc apply -f <(istioctl kube-inject -f full-metrics-tracing.yml)

Expose route

oc expose service ui

Clean up everything

oc delete deployments -l project=mesh-arena
oc delete svc -l project=mesh-arena
oc delete virtualservices -l project=mesh-arena
oc delete destinationrules -l project=mesh-arena

Build the demo

For the first build, it is necessary to get the JS dependencies on your filesystem:

cd services/ui/src/main/resources/webroot/
npm install
# back to project root
cd -

Then build everything:

# Trigger maven build + docker builds
# Ex: for docker namespace "myname" and tag "dev"
./buildall.sh myname dev

Then update all the deployment YAML to have the correct docker tag on images

Generate the full-* templates

./gentemplate.sh
