Kubernetes

Install and attach K2's Node.js Language Agent with your Node.js application hosted on Kubernetes for Runtime Self Application Protection.

We assume here you are able to successfully install our K2 agents in your infrastructure.

Steps to protect Node.js Web Application

There are following options you can select at your convenience for protecting your application workloads

Option 1: (Recommended)

• This assumes you are using one of the Kubernetes’ Volumes/CSI as described in https://kubernetes.io/docs/concepts/storage/volumes/

  • Perform Kubernetes Volume/CSI setup as mentioned here .

  • Mount the created ‘k2-volume-1-10-16-PRODUCTION’ volume at /opt/k2-ic inside your application pod/container using Kubernetes’ volumeMounts like below in your pod spec:

    apiVersion: v1
    kind: Pod 
    metadata:
     name: application-pod
    spec:
     containers:
     - image: k8s.gcr.io/test-webserver
       name: app-container
       volumeMounts:
       - mountPath: /opt/k2-ic
         name: k2-volume-1-10-16-PRODUCTION
     volumes:
     - name: k2-volume-1-10-16-PRODUCTION
     # Your Volume Config here										

  • For Node JS applications, make sure you have Node (version 8.2 and later) installed.

  • The K2-NodeAgent can be statically attached to your application in the following ways:

    • Explicitly running the application with K2-NodeAgent:

      node --require /opt/k2-ic/k2-njs-agent/ <main-module>

    OR

    • Add the following code as the first line of your app's main module:

      require('/opt/k2-ic/k2-njs-agent/k2');

  • To verify if the given application is protected by K2 Prevent-Web, refer to the "Protected processes" subsection of the "Applications" page and locate the application based on name and node IP. The host namespace PID(in case of a host application) and container namespace PID(in case of a containerised application) can also be used to locate the protected application.

  • You can check your application in Protected processes View under applications on K2 Portal. Alternatively go to Applications | K2 Portal

Option 2:

• This method is ideal for a scenario when you don’t have a storage delivery mechanism in your Kubernetes cluster and hence this method requires you to bake-in K2’s Language Collector into your application image via your CI/CD system.

  • For this, please download corresponding Language collector with the following command :

    sudo wget -O k2-njs-agent.tar 'k2io.net/centralmanager/api/v1/help/installers/1.10.16/download/900/96034619811149418751983254798275494295/vm-all.zip?agent_name=node&groupName=PRODUCTION&agentDeploymentEnvironment=PRODUCTION&pullPolicyRequired=true' 

  • Untar contents using the following command:

    sudo tar xf k2-njs-agent.tar

  • Once done, place the extracted contents inside your application’s image at /opt/k2-ic location.

  • For Node JS applications, make sure you have Node (version 8.2 and later) installed.

  • With this modified image of your application, create a pod & attach the K2-NodeAgent using the following ways:

    • Explicitly running the application with K2-NodeAgent:

      node --require /opt/k2-ic/k2-njs-agent/ <main-module>

    OR

    • Add the following code as the first line of your app's main module:

      require('/opt/k2-ic/k2-njs-agent/k2');

  • To verify if the given application is protected by K2 Prevent-Web, refer to the "Protected processes" subsection of the "Applications" page and locate the application based on name and node IP. The host namespace PID(in case of a host application) and container namespace PID(in case of a containerised application) can also be used to locate the protected application.

  • You can check your application in Protected processes View under applications on K2 Portal. Alternatively go to Applications | K2 Portal
