This repository includes the instructions and scripts for running and understanding Istio Service Mesh.

• GCP Free Trial Account
• Apigee Trial Account
• Knowledge on Docker, Microservice Architecture and PaaS platforms

1. After creating an GCP Account,create a new VM in Compute Engine. I have used this config,n1-highcpu-8 - CentOS7 Compute Engine - 8vCPU, 7GB memory, 100GB storage.
2. By default Openshift'spods-per-core is set to10. So in my case I could deploy a total of 80 pods.
3. Reserve aStatic Internal IP Address andStatic External IP Address for the VM Instance.
4. Create a Firewall Rule to allow access to all ports exposed by the VM Instance.
5. Add the above created Rule as aNetwork tag to VM Instance.

• We will installDocker and use it to run Openshift PaaS platform as a Docker container.
• Within scripts folder run all the commands indocker-installation.sh

• We will download Openshift Client and use it to run aoc cluster up command to install Openshift.
• Within scripts folder run all the commands inopenshift-installation.sh

• Within scripts folder go toistio-apigee-installation.sh and edit line 10 to replace yourApigee - organization, environment & credentials.
• We will useApigee Istio Mixer Adapter to setup Istio in Openshift.
• Run all the commands inistio-apigee-installation.sh
• Wait till all thepods are up and running fromistio-system namespace -oc get pods -n istio-system

• All the services are deployed using pre-built docker images fromsiddharth67 Docker repo.
• Within scripts folder run all the commands indeploying-services.sh
• Wait till all thepods are up and running fromaio namespace -oc get pods -n aio

• Runoc get routes -n aio and copy any one of the route and test them in Browser or use a cURL Command,
