QUESTION
I have installed devstack in my server as per this steps and I was looking for some updated instructions to install kubernates cluster in it. Even though my question is on kubernetes I would like to clarify few points.
- Is Openstack opensource ? or the opensource version is called devstack. Because I was trying to install a production ready environment but everywhere I see examples to install devstack or the one is few years old.
- How to Install Openstack not Devstack
And finally can someone please help me with instruction to install kubernetes on devstack as thats the one I could install now and I guess the instructions would be almost similar.
I know there are posts but almost all of them are few years old so a help would be greatly appreciated.

Answered 2021-May-09 at 04:35Hoping that it is allowed to reference my own work: I wrote a short series of articles about Kubernetes on Devstack, both Kubernetes from scratch and using OpenStack Magnum.
The document that you used to install OpenStack describes not Devstack, but Microstack.
OpenStack is 100% open-source, yes. See https://www.openstack.org/.
Devstack is one of the many ways to deploy an OpenStack cloud. Its original purpose is to set up a test environment for OpenStack developers, and not so much to be user-friendly, but it is often used for training or proof-of-concept.
There are many other deployment methods: Microstack (easy but not very flexible), Packstack (requires RHEL or Centos), Tripleo (also requires RHEL or Centos and a bit more powerful hardware), Kolla-Ansible, and the best method for learners in my opinion: Manual setup. This list is far from complete.

I have been working on a simple Node.js application that SETs and GETs a key from etcd using Istio to connect the two services together. I have tried a few variations but keep seeing the same error returned.

Looking at the proxy logs, I can see that client and server proxies are involved in the communication (and this is verified I think in seeing envoy in the server header).

but it looks like your application isn't up - can you check
kubectl get pods
and see nothing is still pending ?

...ANSWER
Answered 2018-Apr-11 at 14:52I guess you want to use nginx as a reverse proxy to your Node.js app. If it is the case, you can use one of the following ways to achieve it.
Option 1
Build nginx and your node.js app into one Docker image. In this image, configure nginx as a reverse proxy and forward the request to your node.js app. For example, the following nginx configure forwards the request to port 3000 in the same container.
