Hi everyone.

I was trying to research about how to implement SSL on the traffic between my clients and the containers that I host on my server.

Basically, my plan was to use upstream SSL in HAProxy to attempt to achieve this, but in order for that to work, each individual container on my server needs to be able to decrypt SSL. I do not think that is possible and that every container has the necessary libraries for it. This puts a halt on my idea for upstream encryption of traffic from my reverse-proxy to my containers.

With that said, ChatGPT suggested I use Kubernetes with a service mesh like Istio. The idea was intriguing so I started to read about it; but before I dive head-first into using k3s (TBH it’s overkill for my setup), is there any way to implement server-side encryption with podman containers and a reverse-proxy?

After writing all of this, I think I’m missing the point about a reverse-proxy being an SSL termination endpoint, but if my question makes sense to you, please let me know your thoughts!

Thanks!

    Thank you, I do realise that each pod uses its own namespace. I was talking about if containers part of a different network namespace (outside of their pods) could also reach out to each other via the loopback address.

      No, they can’t, that’s the point of namespaces.

        Even if containers from different pods are put in an arbitrary namespace?

        Ex:

        • pod 1 - network: pod1
        • pod 2 - network: pod2
        • Container1 and Container2 are spun up within these pods respectively, whilst also being attached to network: pod3

        Will they be able to connect via loopback?
