1. Challenge

   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 "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-Linux-x86_64" -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 https://github.com/istio/istio/releases/download/1.0.6/istio-1.0.6-linux.tar.gz
   [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=172.28.0.1:
   

   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_SERVER_IP>:30080/productpage.

2. Challenge

   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
   

3. Challenge

   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
