Twingate tryout to access private IP from K8s cluster
3 min read
Twingate is Secure access to private data for your distributed workforce. It provides a simple, modern approach to securing online work Twingate enables organisations to rapidly implement a modern zero-trust network that is more secure and maintainable than VPNs. Delivered as a cloud-based service, Twingate empowers IT teams to easily configure a software-defined perimeter without changing infrastructure, and centrally manage user access to internal apps, whether they are on-prem or in the cloud.
In this guide we will see:
How to deploy Twingate connector on Civo Kubernetes via Marketplace
How to setup twingate account
How to install Twingate client application and access private IP's from the cluster
Deploy Twingate Connector on Civo Kubernetes via marketplace
We'll use Civo Kubernetes, which is based on K3s, to experiment with this quickly. If you don’t yet have an account, sign up here. You could also use any other Kubernetes cluster you have access to.
Create a new cluster from the UI (you can also use Civo CLI) and select Twingate app from the marketplace
Once ready you should see the cluster with ready nodes.
Make sure you have kubectl installed, and the kubeconfig file for your cluster downloaded so that you can run kubectl get nodes and get details of the cluster you just created:
kubectl get nodes NAME STATUS ROLES AGE VERSION k3s-twingate-fc341107-node-4c50 Ready <none> 68s v1.20.2+k3s1 k3s-twingate-fc341107-master-eeb3 Ready control-plane,master 78s v1.20.2+k3s1 k3s-twingate-fc341107-node-3fa2 Ready <none> 67s v1.20.2+k3s1
Check the Twingate connector installation
kubectl get pods NAME READY STATUS RESTARTS AGE twingate-connector-7d77f45b9b-g5g5r 0/1 CreateContainerConfigError 0 117s
It will be in
CreateContainerConfigError as we need to create a configmap and secret that will be done in the next step.
Twingate setup walkthrough
In this we will setup Twin gate account and get the tokens for creating configmap and secret
Go to twingate.com to create a trial account and get Started
Signup with your preferred method and enter the team
Select the private resources that you want to access
Add Team members
Select a plan to try out For this demo we just choose Twingate teams
Setup the connector
Add a connector
Generate the tokens
Create following secret with the tokens from above
apiVersion: v1 kind: Secret type: Opaque metadata: name: connector stringData: accessToken: "Access Token" refreshToken: "Refresh Token"
Also create a config map as below Here th eurl will be the once you chose during setup.
apiVersion: v1 kind: ConfigMap metadata: name: connector data: url: https://civo.twingate.com
After creating the configmap and secret you should see the status as connected
Create a deployment
apiVersion: apps/v1 kind: Deployment metadata: name: demo spec: replicas: 1 selector: matchLabels: app: demo template: metadata: labels: app: demo spec: containers: - name: demo image: nginxdemos/hello:latest
Go to the Network and add resource
Add resource with the IP of the pod
kubectl get pods -owide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES demo-58f4cb989b-jzm68 1/1 Running 0 14s 10.42.1.7 k3s-linkerd-60ab3687-node-dcfa <none> <none>
Twingate client application and connecting to the resource created
In this section we will install the Twingate client application on MacOS and then connect to the resource created in above step via the browser.
Now install twingate locally on Mac -> docs.twingate.com/docs/macos
Configure the client app
You will be able to see the network connected and open the deployed application in browser
In this way you can connect the resources within the network from anywhere. These are the private ip's assigned to the pods that you are able to access directly from the browser even without exposing the services!! Let me know on Twitter @SaiyamPathak if you try Twingate out on Civo Kubernetes!
