Make k8s services available globally

 Solution from cloudflare

Create account 

https://www.cloudflare.com/ 

Create a web application and set up your domain. 

Update the nameservers by logging domain registration page. (register.com.np) 

It will take about 24 hours to update your nameserver records until you can start further testing. 

Create tunnel

Zero Trust => Access=> Tunnel and click create tunnel. Provide the tunnel name. 

Then select docker and copy the docker command to run on your server.  The recommended way is to create compose file and set the token as an environmental variable because the token should be very secure.  (.bashrc is one of the places where environmental variables are stored)

docker-compose.yaml

ersion: '3.0'

networks:

minikube:

external: true

services:

cloudflaretunnel:

container_name: cloudflaretunnel-demo-1

image: cloudflare/cloudflared:latest

restart: unless-stopped

environment:

- TUNNEL_TOKEN=$CLOUDFLARE_TUNNEL_TOKEN

command: tunnel --no-autoupdate run

networks:

- minikube

Run this with "docker compose up", and that's it, tunnel creation is done. Now, Cloudflare can forward the traffic from this container to the services running on the server. 

Now, check the created tunnel, if it is shown as "Healthy", we are sure that everything is working so far. 

Now we configure the tunnel. We define the public hostnames and map the services in the local server. 

We provide the ingress ip address in Service URL, with type HTTP. 

In ingress ruleset, this hostname should be configured. And clicking "save hostname", we see the magic, the public hostname "subdomain.domain" will access the service running in your local network. 

So, you don't need to configure anything, no port forwarding, no router settings, no static ip adress. This solution I was looking for 7 years, now I have got it.
