node.js - Kubernetes + consul: kv.get: connect ETIMEDOUT

Question

I have deployed consul using hashicorp-consul-helm-chart now, I want to connect to the consul from my Node.js project.

Therefore, I created an object like this : (using 'consul' npm package)

import consul from 'consul';

var consulObj = new consul({
  host: 'xxx.xxx.xxx.xxx',
  promisify: true
});

var watch = consulObj.watch({
  method: consulObj.kv.get,
  options: { key: 'config' },
  backoffFactor: 1000,
});

I have got the host value from kubectl get endpoints used the value opposite to consul-server

still, i get consul: kv.get: connect ETIMEDOUT when I run the code. what could be the reason? Thanks in advance!

Answer 1

You should be accessing the Consul client which is running on the node where your app is located instead of directly accessing the server.
