3 | # Istio is not just for microservices
4 |
5 | Secure Kubernetes platform services by using Istio Service Mesh. Typically seeing live running code helps users understand how to apply concepts to their own use cases. This project centers around a basic Node.js application demonstrating the power of Istio Service Mesh for persistence datastores such as etcd.
6 |
7 | ## Background on Istio
8 | Istio is an open platform to connect, manage, and secure microservices. To learn more about Istio, please visit the [Intro page]( https://istio.io/about/intro.html).
9 |
10 | ## Setup
11 | Getting started assumes an elementary understanding of Kubernetes. In this project, there are a set of scripts that assume the prior installation of Docker, the Kubernetes CLI as well as jq for manipulating JSON objects returned from the various Kubernetes commands. There is also the assumption around some level of Node.js knowledge.
12 |
13 | **Here are some quick links to the various tools.**
14 | **Docker Install:** https://docs.docker.com/install/
15 | **Kubernetes Install:** https://kubernetes.io/docs/tasks/tools/install-kubectl/
16 | **jq Download:** https://stedolan.github.io/jq/download/
17 | **Node.js Download:** https://nodejs.org/en/download/
18 |
19 | ## Kubernetes Providers
20 | The code below should run on any Kubernetes compliant provider and has been tested on both Minikube and IBM Cloud Private. Depending upon which provider chosen, the instructions will vary slightly.
21 |
22 | ### Minikube
23 | Minikube is available for download and installation instructions are located [here](https://kubernetes.io/docs/tasks/tools/install-minikube/). Minikube provides a simple and easy to use developer environment for learning about Kubernetes.
24 |
25 | ### IBM Cloud Private
26 | IBM provides a Community Edition of their Kubernetes runtime free for development purposes and includes most of the same feature functions as their production version, Enterprise Edition, with the one exception being High Availability. To install IBM Cloud Private, please refer to the [Installation Guide for 2.1.0](https://www.ibm.com/support/knowledgecenter/en/SSBS6K_2.1.0/installing/install_containers_CE.html)
27 |
28 | ## Istio Index Conference 2018 Application
29 | To get started with the code, clone the repo ```git clone git@github.com:todkap/istio-index-conf2018.git```
30 |
31 | ### Kubernetes Setup
32 | - **Minikube:** Prior to deploying to Minikube, Minikube first needs to be started. In the root directory of this project, there is a script ```createMinikubeEnv.sh``` that tears down the previous Minikube environment and initializes a new environment with the appropriate Kubernetes context.
33 |
34 | - **IBM Cloud Private:** IBM Cloud Private has a [configure client](https://www.ibm.com/support/knowledgecenter/en/SSBS6K_2.1.0/manage_cluster/cfc_cli.html) step that will configure the Kubernetes CLI to point to a given IBM Cloud Private installation. This context will be used each time the Kubectl CLI executes commands.
35 |
36 | ### Deploy
37 | #### Kubernetes Installation
38 | This project contains a script that will deploy Istio and the application to Kubernetes called ```deploy.sh```. The script provides verbose output as it progresses through the various steps waiting for the entire system to be in ```Running``` state prior to exiting.
39 |
40 | #### Helm Installation
41 | Starting with IBM Cloud Private version 2.1.0.3, the Istio Control Plane can be installed via a Helm chart as part of the initial install or via the Catalog post installation. Included in this project is an additional script called ```icp-helm-deploy``` that leverages a combination of the IBM Cloud Private CLI, Helm CLI and Kubernetes CLI to install the Istio Index application. In an effort to simplify the deployment process and promote some of the latest features of Istio, I have enabled [automatic sidecar injection](https://istio.io/docs/setup/kubernetes/sidecar-injection.html#automatic-sidecar-injection) for this application.
42 |
43 | ### Testing
44 | This project contains two scripts for testing depending upon which Kubernetes provider that is used. The only difference in the two scripts is the setting of the ingress IP address for IBM Cloud Private. To test choose either ```testICPEnv.sh``` or ```testMinikubeEnv.sh``` based upon your provider.
45 |
46 | In addition to the scripts, there is a lightweight web interface for interacting with the REST APIs.
47 | ![alt text][ui]
48 |
49 | ### Verification
50 | To verify the success of the Istio integration, the script executes a set of tests.
51 |
52 | - The first test verifies a simple put test to the etcd service NodePort to validate connectivity to etcd.
53 | **Example output**
54 | ```

82 |
83 | - The second test verifies that the Node application can handle a simply ping request as well as proxy requests to etcd using the Node applications NodePort.

228 | ### Istio Metrics
229 | Istio provides native enablement for capturimg metrics for network activity. To drive some additional metrics, a simple test script can be run to populate the charts for both Grafana and Promotheus similar to the code below.
230 |
231 | **Test Script**
232 | ```
233 | ## Simple load test using loadtest (https://www.npmjs.com/package/loadtest)
234 | if [ -x "$(command -v loadtest)" ]; then
235 | loadtest -n 400 -c 10 --rps 20 http://$ingressIP:$ingressPort/storage/istioTest
236 | loadtest -n 400 -c 10 --rps 10 http://$ingressIP:$ingressPort/storage/istioTest
237 | loadtest -n 400 -c 10 --rps 40 http://$ingressIP:$ingressPort/storage/istioTest
238 | fi
239 | ```
240 |
241 | #### Grafana
242 | In your Kubernetes environment, execute the following command:
243 | ```
244 | kubectl -n istio-system port-forward $(kubectl -n istio-system get \
245 | pod -l app=grafana -o jsonpath='{.items[0].metadata.name}') 3000:3000 &
246 | ```
247 | Visit http://localhost:3000/dashboard/db/istio-dashboard in your web browser. The Istio Dashboard will look similar to:
248 |
249 | ![alt text][grafana]
250 |
251 | #### Prometheus
252 | In your Kubernetes environment, execute the following command:
253 | ```
254 | kubectl -n istio-system port-forward $(kubectl -n istio-system get \
255 | pod -l app=prometheus -o jsonpath='{.items[0].metadata.name}') 9090:9090 &
256 | ```
257 | Visit http://localhost:9090/graph in your web browser. The Istio Dashboard will look similar to:
258 |
259 | ![alt text][prometheus]
260 |
261 | #### Weave Scope
262 | During the deploy script, Weave Scope was also deployed to the environment. In the console, the port for Weave Scope is logged but is also available using the command.
263 | ```
264 | kubectl get service weave-scope-app --namespace=weave -o 'jsonpath={.spec.ports[0].nodePort}'; echo ''
265 | ```
266 | Weave Scope provides a Service Graph which will display the request flow for the tests executed in the test process. The Weave Scope Dashboard will look similar to:
267 |
268 | ![alt text][weavescope]
269 |
270 | #### Kiali
271 | Kiali is a relatively new project focused on Service Mesh Observability and supports Istio 0.7.1 or later. Inside of this project is a separate script ```setupKiali.s``` that will build and install Kiali as well as apply the appropriate ClusterRole required to run on IBM Cloud Private. To view the console in your environemnt, you will need the NodePort for the servivce. To retrieve the port for Kiali use the following command.
272 | ```
273 | kubectl get service kiali --namespace=istio-system -o 'jsonpath={.spec.ports[0].nodePort}'; echo ''
274 | ```
275 | Kiali provides a Service Graph similar to Weave Scope capable of showing historical view of the request flow as well as other interesting views of your K8 environment such as Services and Tracing. To see this capability in action, the service graph should be viewed after the load test scripts are executed. The Kiali Dashboard will look similar to:
276 |
277 | ![alt text][kiali]

282 | **Istio is not just for microservices on Slideshare:** https://www.slideshare.net/ToddKaplinger/istio-is-not-just-for-microservices
283 |
284 |
285 | ### Notes
286 | - This project is based upon a Medium Article [Istio is not just for microservices](https://medium.com/ibm-cloud/istio-is-not-just-for-microservices-4ed199322bf4) written in 2017 and updated to support the latest version of Istio and Kubernetes. Since most of the content was embedded within the original Medium article, this project was created to encourage developers to clone this repository and modify it to learn more about Kubernetes, Istio and etcd.
287 | - The Node.js application source code is included in the nodejs subdirectory of the project and also includes the Dockerfile and build script for deploying to a Docker registry. Some modifications would be required to publish the image to your own Docker registry and to have the deployment yaml reference the new image but should be relatively easy to figure out if necessary.
