Support wanted for running a registry on localhost about faas HOT 7 CLOSED

Hi @brianjenkins94

I haven't seen anything in your issue that makes it seem like OpenFaaS or K8s wouldn't work in a devcontainer specifically. I think a better title for this issue would be: "How do I use a local registry with OpenFaaS?"

There are some instructions that were contributed based upon a KinD (not an OpenFaaS) guide on how to use a registry on the same machine - https://docs.openfaas.com/tutorials/local-kind-registry/

Setting up a registry on localhost is a bit advanced, perhaps you'd prefer to use a short-lived registry instead like ttl.sh?

We use it a lot for local development and testing.

I'll get this closed, and let us know how you get on with ttl.sh or the KinD project's instructions for local registries.

Delete everything that you have and only run the commands from the tutorial. The port is 5001 and you need to use localhost not the IP.

No problem.

If you'd like to help support the time we spend maintaining OpenFaaS and supporting users via GitHub, please consider setting up a GitHub Sponsorship with a set or custom tier. We want the Community Edition to continue to be available for free users 🙂

Okay, I am now reasonably certain that the problems I am encountering are because I haven't set up a self-signed certificate.

It still seems weird to me that I was able to push the image to the registry without issue, but retrieving it is the problem.

There's something wrong with the volume mount currently. It's getting mounted as an empty folder.

I had absolutely no issues running KinD and OpenFaaS in a devcontainer, and by following the tutorial in the openfaas docs (referenced above), I was also able to use a local registry.

Let me know if this helped 🙂

Hey Alex, I hugely appreciate you taking a look.

You were able to get everything working just by following the KinD guide?

You didn't have to do anything extra with htaccess, certificates, or setting imagePullSecrets?

Weird that I've been running into so many issues. I'll start again from scratch and see if I can make sense of how I got here.

Thanks!

from faas.

It worked 🤦‍♂️

I've updated my previous comment to reflect what worked in the end.

Basically I thought myself smarter than the tutorial and thought I could expose the registry on the host and then get rid of what I had thought would be unnecessary redirection.

Rest assured I feel very silly now 🙂
