Context

I am encountering issues connecting to the Kubernetes ingress host (172.18.1.100:80) after successfully deploying Nebari locally using the "kind" Kubernetes setup. This issue occurs despite the Terraform apply completing without errors.

Error Messages

After deployment, I attempted to connect to the ingress host and received the following error messages:

[terraform]: 
[terraform]: Outputs:
[terraform]: 
[terraform]: load_balancer_address = {
[terraform]:   "hostname" = ""
[terraform]:   "ip" = "172.18.1.100"
[terraform]: }

Attempt 9 failed to connect to tcp tcp://172.18.1.100:80
Attempt 10 failed to connect to tcp tcp://172.18.1.100:80
ERROR: After stage=04-kubernetes-ingress unable to connect to ingress host=172.18.1.100 port=80

Steps to Reproduce

Initialize Nebari in local mode with the following command:

nebari init local  --project localnebari  --domain localhost  --auth-provider password  --terraform-state=local

Deploy Nebari using the generated nebari-config.yaml file:

nebari deploy -c nebari-config.yaml --disable-prompt

Value and/or benefit

Streamlined local deployment process.

Anything else?

Environment Details

Nebari Version: built from source
Kubernetes Version: v0.18.0
Operating System: Ubuntu 22.04 on WSL2
Docker Engine Version: 26.1.4

After the community meeting on Tuesday, I've been trying to locally deploy nebari while following https://www.nebari.dev/docs/how-tos/nebari-local/

There is a strong possibility that i might have been doing something wrong, hence happy to get your help here. Thanks 💐

Hey @arjxn-py

One reason you might be seeing this is because:

Docker containers cannot be executed natively on macOS and Windows, therefore Docker Desktop runs them in a Linux VM. As a consequence, the container networks are not exposed to the host and you cannot reach the kind nodes via IP.

See: https://kind.sigs.k8s.io/docs/user/known-issues/#docker-desktop-for-macos-and-windows

I'm not sure whether this would happen on WSL2 but it's the same error we were getting before on MacOS because the nodes were not being exposed. For Mac, we solved this using https://github.com/chipmk/docker-mac-net-connect

Are you using Docker or Docker Desktop on WSL2? I haven't see anyone deploy Nebari locally on WSL2 but in theory it should be possible as long as the nodes are being exposed.

also, how was your docker installed, are you using the docker desktop?

Thanks for your response @marcelovilla @viniciusdc & apologies for the delay as I am also looking into the same to fix it locally and then report.

Yes I'm using Docker Desktop with WSL2 on windows.

Hi, I was able to get over the above error by uninstalling docker desktop and switching to docker engine natively installed on WSL. Should we also add a note in the docs about this so that other users or contributors do not run in the same issue?

But deploy is still not being able to complete as it's being stuck & timed-out with these logs:

I'd be more than happy to try things you'd suggest further. Thanks 💐

@arjxn-py Try deleting and recreating the test cluster.

Something like kind cluster delete -n test-cluster, and then kind create cluster -n test-cluster.

But deploy is still not being able to complete as it's being stuck & timed-out with these logs:

I confirmed & this was the error because previous resources while trying to deploy were not deleted.
nebari destroy does the work, should we also include this as a note in local deployment docs?

However after this error got resolved, I got this another error which is every time coming just after complete creation of nebari-conda-store-server saying :

FWIW, the first attempt I used demo.com rather than localhost, and encountered similar issues. I used localhost to match original bug report. (I did make sure that the kind cluster was deleted before trying again)

I even tried messing with coredns

  • Is localhost and acceptable domain?
  • Do we need to modify CoreDNS (and add that to the docs?)

If anyone can help me get this set up, I'm happy to update the docs!

Hi @asmacdo @arjxn-py sorry for the delay on following back, let's go in by parts:

This does not directly interfere in your problem but helps as a general service dependency context, if any of these resource get in a crashloop, the usual order of inner dependency between the resources will be:

graph TB
   A[keycloak-postgresql]
   B[keycloak]
   C[jupyterhub]
   D[argo]
   E[conda-store]
   F[conda-store-worker]
   G[jupyterlab-user-pod]
   H(shared-efs-pvc)
   I(conda-store-pvc)
   A --> B
   B --> E
   E --> C
   E --> D
   E --> F
   F -->|volumeMount|I
   C --> G
   G -->|volumeMount|H
   G -->|volumeMount| I

But deploy is still not being able to complete as it's being stuck & timed-out with these logs:

I confirmed & this was the error because previous resources while trying to deploy were not deleted. nebari destroy does the work, should we also include this as a note in local deployment docs?

However after this error got resolved, I got this another error which is every time coming just after complete creation of nebari-conda-store-server saying :

[terraform]: │ Error: client rate limiter Wait returned an error: context deadline exceeded
[terraform]: │
[terraform]: │   with module.kubernetes-conda-store-server.kubernetes_persistent_volume_claim.main,
[terraform]: │   on modules/kubernetes/services/conda-store/worker.tf line 30, in resource "kubernetes_persistent_volume_claim" "main":
[terraform]: │   30: resource "kubernetes_persistent_volume_claim" "main" {

Full Logs
I'm really sorry to be bothering you again as local deployment is something that not many people from the community have been doing. Thanks a lot for your help 💐

There are two things here that could lead to this. Next time this happens, I ask you if you could check for:

  • if there is a user pod running, sometimes that hides the shared and conda-store PVs, blocking it from deletion.
    • So as best practice, always make sure no user is currently running any instances before deletion of the cluster.
  • Now, on another note (and this is a bug I am looking into), when deleting resources, sometimes the conda-store-worker pod stays alive while the PVC and PVC for conda-store are trying to be removed, leading to a timeout as neither of the resources is terminated in time.
    • In such cases, if you see the PV been stuck for a while being terminated, just delete the codna-store-worker, and it should auto-resolve (due to precedence in the requests)

All the problem comes from this:

Is localhost and acceptable domain?

It is unfortunately not accepted, and the reason is while you can expose traefik to this, the other pods, when receiving the domain name (because each process/service runs on a Linux container) will try to reach their internal localhost endpoints, which will cause confusion, as you can see from argo logs for example:

tornado.curl_httpclient.CurlError: HTTP 599: Failed to connect to localhost port 443 after 0 ms: Connection refused

It's trying to request locahost:443 internally within the pod network.

The domain (which needs to be unique*) should act as a mask for an external IP and it's the job of Traefik to forward/proxy that. That said, for a local deployment though, if the purpose is only testing out things, I would recommend just leaving the domain empty, i.e remove it from your nebari-config.yaml file, and you will end up with an address as such:

https://172.18.1.100/hub

which works just fine (except for dask dashboard and the notebook scheduler extension), if you really need a working DNS you can check https://www.nebari.dev/docs/how-tos/domain-registry#what-is-a-dns for some examples on how to set that with CloudFlare. It might also work with you add a subdomain to localhost e.g nebari.localhost but that can also end up being caught by the linux internal hosts for each pod, but its worth trying out.

I would love it if this could be added to our docs, https://github.com/nebari-dev/nebari-docs

Additionally, add missing login info for accessing the newly deployed cluster.

@viniciusdc thank you, dropping the domain worked, I've updated the docs from your comments :)

@arjxn-py I suspect using localhost may have contributed to your problem. I marked this issue as related to this issue (not fixes) since I'm not sure if it will fix things for you.
