Can new Rancher version be used for local cluster only?

Question

I have been working with kubernetes in a staging environment for a couple of month and want to switch to production, I came across a tool called Rancher almost 2 weeks ago and since then am going through their documents.

It was recommended by the developers and also in the community not to use rancher in production kubernete and preferably create a separated cluster for that and add an agent to your main production cluster from that one.

However in the latest stable version, there is actually an option you can tick to use the rancher only for local cluster so this question came to my mind that:

If the latest stable version of rancher is modified to be deployed on production cluster itself rather than having dedicated cluster? and if there is any security or restarting issues can happen that deletes all the configurations for other components on cluster

Note: on another staging environment I installed on the local clustor an instance of wordpress and ghost and both were working fine.

Answer 1

I still think the best option for you would be to have fully accessible own cluster and you wont be dependent to rancher cloud solutions. I am not saying Rancher is bad - no. Just If you are talking about PRODUCTION environment - my personal opinion cluster should be own. Sure arguable topic.

What I can mention also here - you can use any of Useful Interactive Terminal and Graphical UI Tools for Kubernetes . for example Octant

Octant is a browser-based UI aimed at application developers giving them visibility into how their application is running. I also think this tool can really benefit anyone using K8s, especially if you forget the various options to kubectl to inspect your K8s Cluster and/or workloads. Octant is also a VMware Open Source project and it is supported on Windows, Mac and Linux (including ARM) and runs locally on a system that has access to a K8S Cluster. After installing Octant, just type octant and it will start listening on localhost:7777 and you just launch your web browser to access the UI.
