This sample deploys the Bookinfo services across Kubernetes and a set of Virtual Machines, and illustrates how to use Istio service mesh to control this infrastructure as a single mesh.
Overview
Provide a high level overview of what users can expect to learn, why these features are important, and so on. This is not a task, but a feature of Istio.
Before you begin
-
Setup Istio by following the instructions in the [Installation guide](({{home}}/docs/setup/).
-
Deploy the BookInfo sample application.
-
Create a VM named 'db' in the same project as Istio cluster, and Join the Mesh.
Running mysql on the VM
We will first install mysql on the VM, and configure it as a backend for the ratings service.
On the VM:
sudo apt-get update && apt-get install ...
# TODO copy or link the istio/istio test script
Registering the mysql service with the mesh
Machine admin
First step is to configure the VM sidecar, by adding the service port and restarting the sidecar.
On the DB machine:
sudo echo "ISTIO_INBOUND_PORTS=..." > /var/lib/istio/envoy/sidecar.env
sudo chown istio-proxy /var/lib/istio/envoy/sidecar.env
sudo systemctl restart istio
# Or
db$ sudo istio-pilot vi /var/lib/istio/envoy/sidecar.env
# add mysql port to the "ISTIO_INBOUND_PORTS" config
Cluster admin
If you previously run the mysql bookinfo on kubernetes, you need to remove the k8s mysql service:
kubectl delete service mysql
Run istioctl to configure the service (on your admin machine):
istioctl register mysql PORT IP
Note that the 'db' machine does not need and should not have special kubernetes priviledges.
Registering the mongodb service with the Mesh
In progress...
Using the mysql service
The ratings service in bookinfo will use the DB on the machine. To verify it works, you can modify the ratings value on the database.
