This tour guide uses the istio authentication policy and identity platform to display the end users in the applications published in the cloud run of gke. For authentication, the validation logic does not need to belong to the application if istio is used. In this way, you can be responsible for applying application applications and authentication policies in different groups, and apply them to all of multiple application applications or services.

introduce

Gke's cloud run provides a developer center environment for the applications and functions gke runs. This is to provide the development team with a server RIS environment, automatic expansion of requirements, blue green deployment, and Internet management. Gke's cloud run is based on istio and knight and is connected with Google cloud platform (GCP) products.

The next chart shows the basis of this guide.

This guide uses the identity platform to support end-user login, but supports direct debugging of other openid connect providers (such as Google login, firebase authentication, other services (such as auth 0, gluu, OKTA, Ping identity), and openct connect.

Open Cloud shell

Move to cloud sell

Use the cloud shell to execute all the instructions of the tour guide.

The environment variable and gcloud default values for the compute engine area and the name gke claster used in this guide.

gcloud gcloud ZONE=us-central1-c CLUSTER=cloud-run-gke-auth-tutorial gcloud config set compute/zone $ZONE gcloud config set run/cluster $CLUSTER gcloud config set run/cluster_location $ZONE

You can change the zone and client names.

Gke claster used to create cloud run

Create the gke closer for cloud run and istio attachments.

Find public IP address

Gke's cloud run exposes external services to istio ingress gaeway's public IP address.

The istio ingresgateway kubernetes service generates state with an external IP address.

istio-ingressgateway kubectl get services istio-ingressgateway -n istio-system --watch

The external-ip value is converted from pending to IP address. If a notfound error occurs, the command will be rerun after waiting for 1 minute. If you want to interrupt standby, press control + C.

EXTERNAL-IP pending NotFound export EXTERNAL_IP=$(kubectl get services istio-ingressgateway \ --namespace istio-system \ --output jsonpath='{.status.loadBalancer.ingress[0].ip}')

Displays the public IP address of istio ingress gaeway. I need this address in the future.

echo $EXTERNAL_IP

The istio ingresgateway kubernetes service generates state with an external IP address.

istio-ingressgateway istio-ingressgateway kubectl get services istio-ingressgateway -n istio-system --watch

The external-ip value is converted from pending to IP address. If a notfound error occurs, the command will be rerun after waiting for 1 minute. If you want to interrupt standby, press control + C.

EXTERNAL-IP pending NotFound EXTERNAL-IP pending NotFound

An environment variable is created to hold the public IP address of istio ingress gaeway.

export EXTERNAL_IP=$(kubectl get services istio-ingressgateway \ --namespace istio-system \ --output jsonpath='{.status.loadBalancer.ingress[0].ip}')

Displays the public IP address of istio ingress gaeway. I need this address in the future.

echo $EXTERNAL_IP $EXTERNAL_IP

Set up identity platform

Open the cloud shell, access the GCP marketplace, and use the identity platform in a new web browser window.

Move from GCP marketplace to identity platform

Select the GCP project of identity platform in the project location. Gke claster and identity platform can be set in another GCP project. For simplicity, the tour guide uses the same project.

Click identity platform to use the settings.

The current location is the GCP console identity platform vendor page.

Click Add supplier on the supplier page.

Move down from vendor selection and select email / password. The native application can choose the configured vendor.

Confirm that use is selected.

Allow login without password.

Click save.

Move to the identity platform settings page.

Click domain name add. Opening the winning Domain Name dialog.

The public IP address ($external & up IP) of istio ingress gateway searched in the domain name box.

$EXTERNAL_IP

Click mark up. The dialog box closes. The IP address entered is on the winning domain table.

Click Save identity platform configuration page.

Open the cloud shell, access the GCP marketplace, and use the identity platform in a new web browser window.

Move from GCP marketplace to identity platform

Select the GCP project of identity platform in the project location. Gke claster and identity platform can be set in another GCP project. For simplicity, the tour guide uses the same project.

Click identity platform to use the settings.

The current location is the GCP console identity platform vendor page.

Create test user

Create sample application

Sample application for two services issued. One service is to expose the service back-end user interface, and the other service is the back-end API.

Click the application settings details link on the right side of the window. Open the application configuration dialog box.

Display the value of apikey and copy it to the clipboard (Chrome OS / Linux / Windows Control + C, Mac OS CMD + C).

Click close to close the application configuration dialog box.

Cloud shell creates environment variables and saves apikey. Here API key is API key in the application composition dialog box

api-key api-key export AUTH_APIKEY=api-key

Create an environment variable for authdomain.

export AUTH_DOMAIN=$GOOGLE_CLOUD_PROJECT.firebaseapp.com

Clone GitHub's cloud run sample repository.

Switch to a directory of tour guide files.

cd cloud-run-samples/identity-platform/gke

Change the identity platform variable in the foreground JavaScript file.

envsubst frontend/index.template.js frontend/index.js

Sample application distribution

Use cloud build to create the container image of the sample application. One is the front end, the other is the back end.

gcloud builds submit -t gcr.io/$GOOGLE_CLOUD_PROJECT/cloud-run-gke-auth-frontend frontend gcloud builds submit -t gcr.io/$GOOGLE_CLOUD_PROJECT/cloud-run-gke-auth-backend backend

Cloud build saves the image in the container registry.

Create 2 public and API namespaces in gke closer.

public api public api kubectl create namespace public kubectl create namespace api

Distribute the image of the front-end container to the public namespace service and send it to the cloud run of gke.

public public gcloud beta run deploy frontend \ --namespace public \ --image gcr.io/$GOOGLE_CLOUD_PROJECT/cloud-run-gke-auth-frontend \ --platform gke

Send the back-end container image to the service in the API namespace.

api api gcloud beta run deploy backend \ --namespace api \ --image gcr.io/$GOOGLE_CLOUD_PROJECT/cloud-run-gke-auth-backend \ --platform gke

Create a requested istio virtual service with a URI path.

kubectl apply -f istio/virtualservice.yaml

This virtual service will take the request initiated by URI path / API / as the back-end API browsing, and other requests are front-end user interfaces.

/api/ /api/

Verify that the non authentication request for the backend API is successful.

curl -si $EXTERNAL_IP/api/secure.json | head -n1

Add istio certification policy

Create istio certification policy.

envsubst istio/authenticationpolicy.template.yaml | kubectl apply -f -

This policy authenticates URI paths with the exception of / API / API / healtz paths. Istio virtual services rule published in the previous section, which certifies requests from back-end APIs.

/api/ /api/healthz /api/ /api/healthz while sleep 2; do curl -si $EXTERNAL_IP/api/secure.json | head -n1 done

Solution test

$EXTERNAL_IP

This is a direct requirement for back-end APIs The request does not contain enough user authentication information, so origin authentication failed is displayed in the browser window.

Use the external IP address to open the browser window. To display the login form.

$EXTERNAL_IP $EXTERNAL_IP

The test user login used to create the test user.

The test user email address and the secret message is: Hello world are displayed on the web page. It will take some time to display the information.

/api/secure.json frontend/index.js
