[ENH] - Add local support for Mac

[iameskild]

Feature description

It would be nice, as developers, to develop on Mac (and Windows) using a local (kind) deployment.

Value and/or benefit

Currently local deployments are only available for Linux. Adding this would allow those with Macs to develop and prototype more quickly the current workarounds (see dev docs).

Anything else?

Affects all Macs (Apple Silicon + Intel).

[iameskild]

I am currently able to partially deploy on Mac (see branch kind_on_mac). Unfortunately this solution is only partially and quite "hacky". More work will be needed before this is fully usable.

[iameskild]

So far I have tried (or researched) the following with no success:

• UTM virtual machine
• virtualbox virtual machine
  • last time I was reading about this, it wasn't possible to run on Apple Silicon (M1/M2) macs but this might have changed and I will need to give this another try.

@aktech Is your M1 a laptop or a mini/server? How stable is it when you're running it? Is it useable at all? I have a 10-core M1 laptop with 32 gigs of RAM. Using the new docs/config above, I managed to deploy it by putting the domain in the hosts file (172.18.1.100 nebari.example.com) and installing/enabling docker-mac-net-connect. Then the laptop fans started spinning very fast and the cluster crashed and never recovered, which was after starting JupyterLab and attempting to build a single empty conda-store env. So it looks like it has limited usefulness on a laptop unless there's a way to reduce resource usage of the K8s cluster. Thoughts?

[marcelovilla]

@nkaretnikov I just tried Amit's config now on a 8-core M1 with 32GB and was able to spin a small Jupyter server up and create a simple conda environment with numpy on it. I think the local cluster has already some memory restrictions because I was not able to spin a medium size server up.

[nkaretnikov]

OK, turns out there are a bunch of issues on Mac with Docker. So I think the stability/crashes/disconnects were solved by me updating everything to latest, but I also didn't test extensively:

• I had to update Docker Desktop
• I had to install K8s via Docker Desktop instead of using minikube with brew (it can be done via the settings in the UI)
• I had to update macOS to latest because there were crashes in Virtual Machine Service, which are related to Linux kernel support. Before that, I also saw high CPU usage by this service when running Docker
• I had to create this symlink because Docker no longer creates it and terraform cannot find the socket otherwise:

sudo ln -s "$HOME/.docker/run/docker.sock" /var/run/docker.sock

However, I still cannot get argo workflows working. These are disabled in the config provided by Amit. I needed them for my work, so I set them to true, but then I saw that the nebari-workflow-controller was in the failed state trying to pull the image, so I attempted to do (this image is available on quay):

default_images:
...
  nebari_workflow_controller: quay.io/nebari/nebari-workflow-controller:m1-image

But it's not possible to set this image via the config because the key is not supported. So I patched this Python file instead:

./lib/python3.10/site-packages/_nebari/constants.py:

DEFAULT_NEBARI_WORKFLOW_CONTROLLER_IMAGE_TAG = "m1-image"

This seemed to solve the problem with the image pull, but the workflows still immediately fail. I did check a bunch of logs in various pods, but I didn't find anything. Not sure where it's supposed to be logged if at all. It's still possible that the change above is not sufficient to use this image correctly. And yes, I did add relevant permissions for my user to be able to use argo in Keycloak.

If someone can get argo workflows working (scheduling a notebook via the JLab UI), let me know. But for now, I'm going to use the cloud again because it's not clear how much more work is needed here.

@aktech Is your M1 a laptop or a mini/server? How stable is it when you're running it? Is it useable at all? I have a 10-core M1 laptop with 32 gigs of RAM.

I have a M1 Pro laptop (32GB, 10 cores). It is very stable for me. I have conda environment built with packages required create apps. I never had a cluster crash. Do you have anything else running other than kind cluster?

I am using docker desktop 4.30.0 (149282)

[nkaretnikov]

@aktech Yeah, ignore the crash issue. I think it was resolved by updating everything to latest. I'm now more interested in how to get argo-workflows working locally. Have you tried that? They are disabled in your original config.

I should have mentioned that, I didn't needed argo, so didn't bothered adding it to config.

I can give it a try, let me try the m1-image you shared above.

Also, apologies for the late reply.

[aktech]

I deployed argo with the latest image 2024.6.1rc3, it deployed successfully. The notebook scheduling didn't wor. Looks like TLS verification failed while connecting to the API, which is expected as I am running it locally without proper certs. We would probably need to toggle TLS verification to avoid this. Is this what you saw as well?

[nkaretnikov]

I cannot recall at this point, but I agree that fixing the cert issue would be a good first step to resolving this.

[krassowski]

I see the exact same certificate error, c-f nebari-dev/argo-jupyter-scheduler#10 (comment). I tried to disable SSL verification but only got me half way thought (the error message changed but did not disappear)

If anyone wants to pick up: nebari-dev/argo-jupyter-scheduler@main...krassowski:argo-jupyter-scheduler:km-papermill-error-2

[aktech]

That's a good starting point, thanks @krassowski do you recall what was the new error message?

[krassowski]

See nebari-dev/argo-jupyter-scheduler#10 (comment) (but maybe it is me issue and I have something misconfigured - so maybe the changes linked above are sufficient - though we need to ensure to only apply them when running a local deployment, so possibly something controlled by an environment variable)

[aktech]

I have got the notebook scheduler working after setting up real valid certs in my local deployment. I can confirm it's certainly an ssl issue.

Completed Pods

Completed Job

[aktech]

I shared this in slack, I think it might be useful for others as well:

Local deployment with lets encrypt certs: (without certs some things do not work out of the box, like argo notebook scheduler, etc)

For anyone interested: . You can setup let's encrypt certs with DNS challenge locally (if you have a domain or can use a subdomain in quansight domains), this basically verifies that you control the domain, by using domain provider's API token, provided by you to let's encrypt. I think its definitely worth setting it up to get a full production environment locally. Here is the branch for setting it up, if anyone want to try: https://github.com/nebari-dev/nebari/compare/dns-challenge?expand=1 (You need to create an API token from cloudflare for the domain you're using)

We should consider adding the support natively. It's specially useful for Nebari deployments with non-public IP addresses (like inside a private network).

[marcelovilla]

Thanks to @aktech we can now deploy on Mac! Should we keep this issue open or close it for now and open a specific one for windows?

[kcpevey]

@marcelovilla at this point, is there any special setup required to deploy locally on mac?

[marcelovilla]

@kcpevey there are two things that need to be configured:

1. We need to use a specific ARM image for Keycloack
2. We need to setup https://github.com/chipmk/docker-mac-net-connect so the container IPs are exposed.

There's a PR outlining these two steps.

I'm happy to help you deploy it locally if you ever need to.

[marcelovilla]

I edited the title of this issue so it's only about local support for Mac. We can open another specific issue for Windows when/if we think it's relevant.

[kcpevey]

Thanks @marcelovilla I was just wanting to make sure we had documentation on the "how", so it looks like that's all taken care of :)

The docs are now published here.
