Adding Conda-Store to QHub #967

costrouc · 2021-12-09T21:36:25Z

Changes:

This PR bring the new Conda-Store to QHub. In the process of adding Conda-Store we needed a database along with s3 storage. This requires adding the minio and postgres helm charts included in this PR.

Hello @costrouc, I will have a look and review this

viniciusdc

There is just one thing I could find and I noticed that you used, var.conda-store-image I couldn't spot its reference anywhere, and you seem to use that to retrieve the tag and name components from it

docs/source/dev_guide/minikube.md

docs/source/installation/existing.md

qhub/template/{{ cookiecutter.repo_directory }}/infrastructure/kubernetes.tf

+ external-url = var.endpoint
+
+{% if cookiecutter.certificate.type == "existing" %}
+ certificate-secret-name = "{{ cookiecutter.certificate.secret_name }}"


This will follow the same approach we did for clearml right? when using a provisioned certificate

Service Unavailable when deploying on GCP, hub is on CrashLoop caused by... qhub-jupyterhub-theme

This must be because you are using an older Docker image for hub. It needs to include qhub-jupyterhub-theme v0.3.3 as is specified on main here.

So you need to work out which tag of quansight/qhub-jupyterhub is needed to pick this up. In theory this is quansight/qhub-jupyterhub:fix-798 to pick up the images based on the PR. But it is possible that the PR needs to be rebased - the strange thing is that it has picked up the commit to jupyterhub_config.py.j2 that attempts import theme_extra_handlers from qhub_jupyterhub_theme but does not have the correct version built into the image. Or it's possible you just have an older tag left in your qhub-config.yaml that picks up an older Docker image.

That might be the case Dan, thanks for the pointer

Hi @costrouc , I just tested the deployment for this PR it seems that there might be some changes with the Jupyterhub docker image as the following error showed up during deployment:

│ Loading /usr/local/etc/jupyterhub/secret/values.yaml
│ No config at /usr/local/etc/jupyterhub/existing-secret/values.yaml
│ Loading extra config: jupyterhub_extra_config 
│ [C 2022-01-13 17:15:39.728 JupyterHub application:90] Bad config encountered during initialization: 
The 'spawner_class' trait of <jupyterhub.app.JupyterHub object at 0x7fd9af233110> instance must be a type, but 
cdsdashboards.hubextension.spawners.variablekube.VariableKubeSpawner' could not be imported

Using the main one instead resulted in any issues.

Hi @costrouc, by some reason the icons for some buttons are not showing up correctly

viniciusdc · 2022-01-14T21:05:06Z

Just finished testing, all seems fine with conda-store. I will proceed to test the minio port changes, then will test on GCP as well to confirm. My only concern is within the issue with the main jupyterhub image..

ps. Also, not sure about this one, but there might be a duplicate constraint somewhere in the postsql config:
ERROR: duplicate key value violates unique constraint "_conda_package_uc"

* FEAT: Add additional port to handle Minio object storage * Add missing vars * Update minio entrypoint and disable tls * Exclude traitlets config from pre-commit * Update conda-store minio service eternal endpoint Co-authored-by: viniciusdc <vinivdc2009@hotmail.com>

Per #987

minio is AGPLv3 which means might we can't include it.
