Istio in Docker

About this Hands-on Lab

In this hands-on lab, we will be installing Istio into a Docker environment. We’ll deploy an application and using routing rules to version it.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install Istio and Its Dependencies for Docker, Then Deploy the bookinfo Application

Add current user to docker group:

sudo usermod -aG docker cloud_user

Install docker-compose and make it executable:

[cloud_user@host]$ sudo curl -L "" -o /usr/local/bin/docker-compose  
[cloud_user@host]$ sudo chmod +x /usr/local/bin/docker-compose

We’ll run docker-compose real quick, just to make sure it works before we proceed. We’ll see its help output if all is well.

Now we can download Istio and unpack it:

[cloud_user@host]$ wget
[cloud_user@host]$ tar -xvf istio-1.0.6-linux.tar.gz

Pre-configure kubectl for pilot:

[cloud_user@host]$ kubectl config set-context istio --cluster=istio
[cloud_user@host]$ kubectl config set-cluster istio --server=http://localhost:8080
[cloud_user@host]$ kubectl config use-context istio

Create a DOCKER_GATEWAY environment variable:

[cloud_user@host]$ export DOCKER_GATEWAY=

Bring up Istio’s control plane:

[cloud_user@host]$ docker-compose -f ./istio-1.0.6/install/consul/istio.yaml up -d

Remember that this may need to be repeated to ensure the pilot container starts.

Change bookinfo.yaml, and set port 30080 instead of port 9081:

[cloud_user@host]$ sed -i 's/9081/30080/' ./istio-1.0.6/samples/bookinfo/platform/consul/bookinfo.yaml

Bring up the application:

[cloud_user@host]$ docker-compose -f ./istio-1.0.6/samples/bookinfo/platform/consul/bookinfo.yaml up -d

Bring up the sidecars:

[cloud_user@host]$ docker-compose -f ./istio-1.0.6/samples/bookinfo/platform/consul/bookinfo.sidecars.yaml up -d

Point a browser at the public IP address of the server, on the correct port: _http://<PUBLIC_SERVERIP>:30080/productpage.

Route Application Traffic to reviews Version 1 and Confirm that Version 1 (with No Stars) is Loading

Route traffic to version 1

kubectl apply -f ./istio-1.0.6/samples/bookinfo/platform/consul/destination-rule-all.yaml
kubectl apply -f ./istio-1.0.6/samples/bookinfo/platform/consul/virtual-service-all-v1.yaml
Route the Traffic to Version 3 of the reviews Service (with Red Stars)

We need to modify the routing service subsets to read the labels for Version 3. Edit istio-1.0.6/samples/bookinfo/platform/consul/virtual-service-all-v1.yaml (using whatever text editor you like) and change the subset to V3 in the reviews section. Then apply the changes with:

[cloud_user@host]$ kubectl apply -f ./istio-1.0.6/samples/bookinfo/platform/consul/virtual-service-all-v1.yaml

Additional Resources

Our organization has determined that we need to provide application versioning for our Docker-deployed application. We will need to install Istio and deploy the bookinfo application. Then we'll need to verify that it is loading only version 1 of the application (which has no review stars). Afterward, we'll need to route traffic to version 3 of the application (which has red stars).
