Deploy sample apps

These sample apps are used throughout the documentation to help test connectivity, such as in the traffic management, security, and resiliency policy guides.

Bookinfo link

1. Create the bookinfo namespace.

     kubectl create ns bookinfo
     

   For more information, see the Istio on OpenShift documentation.

   1. Create the bookinfo project.

        kubectl create ns bookinfo
        

   2. Create a NetworkAttachmentDefinition custom resource for the bookinfo project.

        cat <<EOF | oc -n bookinfo create -f -
      apiVersion: "k8s.cni.cncf.io/v1"
      kind: NetworkAttachmentDefinition
      metadata:
        name: istio-cni
      EOF
        

   3. Elevate the permissions of the bookinfo service account to allow the Istio sidecars to make use of a user ID that is normally restricted by OpenShift.

        oc adm policy add-scc-to-group anyuid system:serviceaccounts:bookinfo
        

2. Deploy the Bookinfo app.

     # deploy bookinfo application components for all versions less than v3
   kubectl -n bookinfo apply -f https://raw.githubusercontent.com/istio/istio/1.18.7/samples/bookinfo/platform/kube/bookinfo.yaml -l 'app,version notin (v3)'
   # deploy an updated product page with extra container utilities such as 'curl' and 'netcat'
   kubectl -n bookinfo apply -f https://raw.githubusercontent.com/solo-io/gloo-mesh-use-cases/main/policy-demo/productpage-with-curl.yaml
   # deploy all bookinfo service accounts
   kubectl -n bookinfo apply -f https://raw.githubusercontent.com/istio/istio/1.18.7/samples/bookinfo/platform/kube/bookinfo.yaml -l 'account'
     

3. Verify that the Bookinfo app is deployed successfully.

     kubectl get pods -n bookinfo
   kubectl get svc -n bookinfo
     

httpbin link

The httpbin sample app is a simple tool to test HTTP requests and responses. Unlike curl, you can see not only the response headers, but also the request headers.

1. Create an httpbin namespace.

     kubectl create ns httpbin
     

   1. Create the httpbin project.

        kubectl create ns httpbin
        

   2. Create a NetworkAttachmentDefinition custom resource for the httpbin project.

        cat <<EOF | oc -n httpbin create -f -
      apiVersion: "k8s.cni.cncf.io/v1"
      kind: NetworkAttachmentDefinition
      metadata:
        name: istio-cni
      EOF
        

   3. Elevate the permissions of the httpbin service account to allow the Istio sidecars to make use of a user ID that is normally restricted by OpenShift.

        oc adm policy add-scc-to-group anyuid system:serviceaccounts:httpbin
        

2. Deploy the httpbin app.

     kubectl -n httpbin apply -f https://raw.githubusercontent.com/solo-io/gloo-mesh-use-cases/main/policy-demo/httpbin.yaml
     

3. Verify that the httpbin app is running.

     kubectl -n httpbin get pods
     

Optional: Install Keycloak link

You might want to test how to restrict access to your applications to authenticated users, such as with external auth or JWT policies. You can install Keycloak in your cluster as an OpenID Connect (OIDC) provider.

The following steps install Keycloak in your cluster, and configure two user credentials as follows.

• Username: user1, password: password, email: user1@example.com
• Username: user2, password: password, email: user2@solo.io

Install and configure Keycloak:

1. Create a namespace for your Keycloak deployment.

     kubectl create namespace keycloak
     

2. Create the Keycloak deployment.

     kubectl -n keycloak apply -f https://raw.githubusercontent.com/solo-io/workshops/master/gloo-mesh-2-3/all/data/steps/deploy-keycloak/keycloak.yaml
     

3. Wait for the Keycloak rollout to finish.

     kubectl -n keycloak rollout status deploy/keycloak
     

4. Set the Keycloak endpoint details from the load balancer service.

     export ENDPOINT_KEYCLOAK=$(kubectl -n keycloak get service keycloak -o jsonpath='{.status.loadBalancer.ingress[0].*}'):8080
   export HOST_KEYCLOAK=$(echo ${ENDPOINT_KEYCLOAK} | cut -d: -f1)
   export PORT_KEYCLOAK=$(echo ${ENDPOINT_KEYCLOAK} | cut -d: -f2)
   export KEYCLOAK_URL=http://${ENDPOINT_KEYCLOAK}/auth
   echo $KEYCLOAK_URL
     

5. Set the Keycloak admin token. If you see a parsing error, try running the curl command by itself. You might notice that your internet provider or network rules are blocking the requests. If so, you can update your security settings or change the network so that the request can be processed.

     export KEYCLOAK_TOKEN=$(curl -d "client_id=admin-cli" -d "username=admin" -d "password=admin" -d "grant_type=password" "$KEYCLOAK_URL/realms/master/protocol/openid-connect/token" | jq -r .access_token)
   echo $KEYCLOAK_TOKEN
     

6. Use the admin token to configure Keycloak with the two users for testing purposes. If you get a 401 Unauthorized error, run the previous command and try again.

     # Create initial token to register the client
   read -r client token <<<$(curl -H "Authorization: Bearer ${KEYCLOAK_TOKEN}" -X POST -H "Content-Type: application/json" -d '{"expiration": 0, "count": 1}' $KEYCLOAK_URL/admin/realms/master/clients-initial-access | jq -r '[.id, .token] | @tsv')
   export KEYCLOAK_CLIENT=${client}
   
   # Register the client
   read -r id secret <<<$(curl -X POST -d "{ \"clientId\": \"${KEYCLOAK_CLIENT}\" }" -H "Content-Type:application/json" -H "Authorization: bearer ${token}" ${KEYCLOAK_URL}/realms/master/clients-registrations/default| jq -r '[.id, .secret] | @tsv')
   export KEYCLOAK_SECRET=${secret}
   
   # Add allowed redirect URIs
   curl -H "Authorization: Bearer ${KEYCLOAK_TOKEN}" -X PUT -H "Content-Type: application/json" -d '{"serviceAccountsEnabled": true, "directAccessGrantsEnabled": true, "authorizationServicesEnabled": true, "redirectUris": ["'https://${ENDPOINT_HTTPS_GW_CLUSTER1}'/callback"]}' $KEYCLOAK_URL/admin/realms/master/clients/${id}
   
   # Add the group attribute in the JWT token returned by Keycloak
   curl -H "Authorization: Bearer ${KEYCLOAK_TOKEN}" -X POST -H "Content-Type: application/json" -d '{"name": "group", "protocol": "openid-connect", "protocolMapper": "oidc-usermodel-attribute-mapper", "config": {"claim.name": "group", "jsonType.label": "String", "user.attribute": "group", "id.token.claim": "true", "access.token.claim": "true"}}' $KEYCLOAK_URL/admin/realms/master/clients/${id}/protocol-mappers/models
   
   # Create first user
   curl -H "Authorization: Bearer ${KEYCLOAK_TOKEN}" -X POST -H "Content-Type: application/json" -d '{"username": "user1", "email": "user1@example.com", "enabled": true, "attributes": {"group": "users"}, "credentials": [{"type": "password", "value": "password", "temporary": false}]}' $KEYCLOAK_URL/admin/realms/master/users
   
   # Create second user
   curl -H "Authorization: Bearer ${KEYCLOAK_TOKEN}" -X POST -H "Content-Type: application/json" -d '{"username": "user2", "email": "user2@solo.io", "enabled": true, "attributes": {"group": "users"}, "credentials": [{"type": "password", "value": "password", "temporary": false}]}' $KEYCLOAK_URL/admin/realms/master/users
