IBM Cloud App ID

Node Sample Template App for the IBM Cloud App ID service. The App ID Dashboard overwrites the manifest.yml and localdev-config.json files with the user's information when they download a Node sample app. When downloaded, you can either run the application locally or in IBM Cloud.

Contents

app.js Uses Express to set the routes.

public/index.html The application landing page. Click Login to start.

protected/protected.html The application's protected page. After clicking the Login button, the user is redirected here. This is where we check whether the user is authorized or not. In the case where the user is not authorized, we send a request to the authentication server to start the OAuth flow. If the user is authorized, we show the protected data.

Requirements

• Node 6.0.0 or higher

Running Locally

Run the following commands:

npm install
npm start

Use the link http://localhost:3000 to load the web application in browser.

Running in Kubernetes

Prerequisites

Before you begin make sure that IBM Cloud CLI, docker and kubectl installed and that you have a running kubernetes cluster. You also need an IBM Cloud container registry namespace (see https://cloud.ibm.com/kubernetes/registry/main/start). You can find your registry domain and repository namespace using ibmcloud cr namespaces.

Deployment

Note: Your App ID instance name must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character. You can visit the App ID dashboard to change your instance name.

1. Login to IBM Cloud.

   ibmcloud login -a https://api.{{domain}}

2. Run the following command, it will output an export command.

   ibmcloud ks cluster-config {CLUSTER_NAME}

3. Set the KUBECONFIG environment variable. Copy the output from the previous command and paste it in your terminal. The command output looks similar to the following example:

   export KUBECONFIG=/Users/$USER/.bluemix/plugins/container-service/clusters/mycluster/kube-config-hou02-mycluster.yml

4. Bind the instance of App ID to your cluster.

   ibmcloud ks cluster service bind -c {CLUSTER_NAME} -n default --service {APP_ID_INSTANCE_NAME}

5. Find your cluster's public endpoint {CLUSTER_ENDPOINT}.

   Note: If you are using the free version of kubernetes (with only 1 worker node) you can use your node's public IP instead, which you can find using:

   ibmcloud ks workers {CLUSTER_NAME}

6. Edit the kube_deployment.yml file.

   1. Edit the image field of the deployment section to match your image name. The name of your image should be {REGISTRY_DOMAIN}/{REPOSITORY_NAMESPACE}/appid-node-sample:{APP_VERSION}).
   2. Edit the Binding name field to match yours. It should be binding-{APP_ID_INSTANCE_NAME}.
   3. Edit redirectUri's value to include your cluster's IP. The value should be http://{CLUSTER_ENDPOINT}/ibm/cloud/appid/callback
   4. Optional: Change the value of metadata.namespace from default to your cluster namespace if you’re using a different namespace.

7. Build your Docker image.

   docker build -t {REGISTRY_DOMAIN}/{REPOSITORY_NAMESPACE}/appid-node-sample:{APP_VERSION} .

8. Push the image.

   docker push {REGISTRY_DOMAIN}/{REPOSITORY_NAMESPACE}/appid-node-sample:{APP_VERSION}

   kubectl apply -f kube_deployment.yml

9. Now configure the OAuth redirect URL at the App ID dashboard so it will approve redirecting to your cluster. Go to your App ID instance at IBM Cloud console and under Manage Authentication->Authentication Settings->Add web redirect URLs add the following URL:

   https://{CLUSTER_ENDPOINT}:30000/ibm/cloud/appid/callback

10. You can see your sample running on Kubernetes in IBM Cloud.

    open http://{CLUSTER_ENDPOINT}:30000

Clarification

This sample runs on one instance and uses the session to store the authorization data. In order to run it in production mode, use services such as Redis to store the relevant data.
