Hello,

sorry for such a newbie question, can you please advise how to customize JupyterHub Login page when using Kubernetes.

It is easy to edit login.html directly in JupyterHub installation, however when using Kubernetes (and helm chart) I am not sure how to do this?

What is the right approach from your point of view?

Thank you very much for any idea or advice that would help move into right direction.

Regards,  
Peter

I’m having trouble with this too. Have you had any luck?

Hi,

You have to put the path, where your custom template takes place, into [template\_paths](https://github.com/jupyterhub/jupyterhub/blob/915664ede2081838ae18f19806d7b8ecc422eae6/jupyterhub/app.py#L361) config of jupyterhub (see [custom templates documentation](https://jupyterhub.readthedocs.io/en/stable/reference/templates.html?highlight=template_paths#custom-templates)):

```auto
jupyterhub:
  hub:
    extraConfig:
      templates: |
        c.JupyterHub.template_paths = ['/path/to/custom/templates']

```

And this path and templates must exist in jupyterhub container. There are 2 ways (that I am aware of) to do this. First you can extend the jupyterhub image by copying the templates and use this image in your config. But this means that you have to create a new image everytime you upgrade your jupyterhub. Second way, which I prefer, you can use `initContainers`, by which you can clone/download your custom templates into a volume and then you can mount this volume into the hub container. Here is an example config for that:

```auto
jupyterhub:
  hub:
    # clone custom JupyterHub templates into a volume
    initContainers:
      - name: git-clone-templates
        image: alpine/git
        args:
          - clone
          - --single-branch
          - --branch=master
          - --depth=1
          - --
          - https://github.com/your/repo.git
          - /etc/jupyterhub/custom
        securityContext:
          runAsUser: 0
        volumeMounts:
          - name: custom-templates
            mountPath: /etc/jupyterhub/custom
    extraVolumes:
      - name: custom-templates
        emptyDir: {}
    extraVolumeMounts:
      - name: custom-templates
        mountPath: /etc/jupyterhub/custom

    extraConfig:
      templates: |
        c.JupyterHub.template_paths = ['/etc/jupyterhub/custom/jupyterhub/templates']

```

This config clones the repo ([https://github.com/your/repo.git](https://github.com/your/repo.git), you have to change this with the url of repo where your custom templates are) into `/etc/jupyterhub/custom` folder, to where the `custom-templates` volume is mounted. The same volume will be mounted into hub container too (see `extraVolumeMounts` config). Finally we have to tell jupyterhub where to find custom templates, for that we have to set `c.JupyterHub.template_paths` as mentioned before. For example if your templates exist in `jupyterhub/templates` folder in your repo, then set it to `['/etc/jupyterhub/custom/jupyterhub/templates']` as I did in the example config.

I hope this helps 🙂

❤ @bitnik for your example!

Another perhaps more complicated option is to mount configmaps with the template files, the benefit is that you don’t need to have an init container do stuff but instead mounts things directly assuming you have these files available on `helm upgrade` etc and some additional configuration work.

To use this approach, do something like below. Note that this is a WIKI post allowing you to edit it if you find something to correct or add, please feel free to do so!

1. use a custom helm chart that requires the jupyterhub helm chart

2. add some template files in a local folder alongside helm chart configuration files

3. make a configmap helm template add these files to itself

4. and then mount that configmap to the hub pod

Thank you @consideRatio and @bitnik for your detailed examples and explanations! I will try them out.

Could I ask how you knew what values to put under `extraVolumes` or `extraVolumeMounts`? I looked over [values.yaml](https://github.com/jupyterhub/zero-to-jupyterhub-k8s/blob/154913a496b6f8fbaa20f3a3e641c548832ddafa/jupyterhub/values.yaml) but didn’t know what parameters to put (e.g.`name` and `configMap` under `extraVolumes`).

Another quick question:

```auto
extraConfig:
      templates: |
        c.JupyterHub.template_paths = ['/etc/jupyterhub/custom/jupyterhub/templates']

```

I’ve seen in the documentation where `templates` is replaced with other keywords, such as `myConfig.py`. Does the keyword chosen matter?

I had to depended on previous knowledge about Kubernetes, Helm, and inspiration from [mybinder.org’s configuration](https://github.com/jupyterhub/mybinder.org-deploy/blob/72509b4c8e274c0d8b3a2f1503110637c3e2ed31/mybinder/values.yaml#L222-L233). It took quite a while to get this right for me.

One challenge that I struggled with was referencing images from my template:

```
<img src="/hub/static/external/my-custom-image.svg" height="80px" />

```

The question I asked myself was what content would the webserver that JupyterHub use try to serve if we wrote that? I figured out by some testing and source code inspection, that something within a HTML reference to `/hub` will map to content on a hard drive where JupyterHub’s [`data_files_path`](https://jupyterhub.readthedocs.io/en/stable/api/app.html) is configured to point to. I did not reconfigure this location but instead used the default value, which was `/usr/local/share/jupyterhub/`, and placed a folder of stuff within it using a ConfigMap.

I’m not 100% that you mean this, but…

```yaml
extraConfig:
  whateverYouWantItDoesntMatter: |
    c.JupyterHub.template_paths = ['/etc/jupyterhub/custom/jupyterhub/templates']

```

Making extraConfig a dictionary of key value pairs allows extraConfig information from one file to be merged with another better. This could be useful if you have two config.yaml files, one for example being secret-config.yaml, and one being non-secret-config.yaml, and both wanted to add some extraConfig. If both these files had written a string value to extraConfig like we actually do using the `|` symbol in the YAML syntax, they would override instead of merge in a meaningful way. By introducing a key/value pair in between we can avoid this. That is the only purpose it serves though, so you can name it whatever you like. When the configuration snippets is executed listed under `extraConfig`, it will be done so in an alphabetical order based on the key name.

```yaml
extraConfig:
  config1: |
    print("will execute first")
    print("PS: this is Python")
  config2: |
    print("will execute second")

```

I tried using an init container as you said. I can tell that `/etc/jupyterhub custom` is created, nothing is inside it. Maybe it cloned the files incorrectly?

The more relevant part of `config.yaml`:

```auto
hub:
  # Clone custom JupyterHub templates into a volume
  initContainers:
    - name: git-clone-templates
      image: alpine/git
      args:
        - clone
          - --single-branch
          - --branch=master
          - --depth=1
          - --
        - https://github.com/LibreTexts/jupyterhub-templates.git
        - /etc/jupyterhub/custom
      securityContext:
        runAsUser: 0
      volumeMounts:
        - name: custom-templates
          mountPath: /etc/jupyterhub/custom
  extraVolumes:
    - name: custom-templates
      emptyDir: {}
  extraVolumeMounts:
    - name: custom-templates
      mountPath: /etc/jupyterhub/custom

  extraConfig:
    templates: |
      c.JupyterHub.template_paths = ['/etc/jupyterhub/custom/jupyterhub/templates']
    jupyterlab: |
      c.Spawner.cmd = ['jupyter-labhub']

```

Here’s the rest of it, if it’s applicable:

```auto
proxy:
  secretToken: <token>

    letsencrypt:

```

I also tried @consideRatio’s solution with slightly different folder paths and reached a similar problem (although I may have botched the `helm install` of the chart, will try again soon). So it’s most likely a problem on my end?

There are some extra spaces in `hub.initContainers.args` (after clone command). Actually this should make `git-clone-templates` container fail and hub shouldn’t start at all. And also with that config you should set `c.JupyterHub.template_paths` to `['/etc/jupyterhub/custom']`. Here is updated version of your config:

```auto
hub:
  # Clone custom JupyterHub templates into a volume
  initContainers:
    - name: git-clone-templates
      image: alpine/git
      args:
        - clone
        - --single-branch
        - --branch=master
        - --depth=1
        - --
        - https://github.com/LibreTexts/jupyterhub-templates.git
        - /etc/jupyterhub/custom
      securityContext:
        runAsUser: 0
      volumeMounts:
        - name: custom-templates
          mountPath: /etc/jupyterhub/custom
  extraVolumes:
    - name: custom-templates
      emptyDir: {}
  extraVolumeMounts:
    - name: custom-templates
      mountPath: /etc/jupyterhub/custom

  extraConfig:
    templates: |
      c.JupyterHub.template_paths = ['/etc/jupyterhub/custom']

```

Can you try this?

My bad, I initially wrote `c.JupyterHub.template_paths = ['/etc/jupyterhub/custom']`; I changed it to `c.JupyterHub.template_paths = ['/etc/jupyterhub/custom/jupyterhub/templates']` while trying to debug. The extra spaces might have come from me copying from a backup file that wasn’t `.yaml`.

I tried using your config, nothing seems to be in `/etc/jupyterhub/custom` in the `hub-` pod still.

The `custom` folder seems to be mounted (although I’m not sure if that’s the right location):

```auto
$ kubectl exec hub-<name> -n jhub -ti bash
$ $ cat /etc/mtab | grep "custom"
/dev/mapper/VGsys-main /etc/jupyterhub/custom ext4 rw,relatime,errors=remount-ro,data=ordered 0 0

```

The `hub` pod is definitely running and I can access JupyterHub. So I do think that the initContainers did run or they somehow weren’t recognized.

I also tried disabling the firewall via `sudo ufw disable`, files still didn’t appear.

Yes it looks like `initContainers` were not started at all. Which version of JupyterHub chart are you using? Version 0.8.2 as from documentation? `initContainers` config is added into hub at version 0.9-38e1b89 ([https://github.com/jupyterhub/zero-to-jupyterhub-k8s/pull/1274/](https://github.com/jupyterhub/zero-to-jupyterhub-k8s/pull/1274/)). Sorry that I didn’t think about this before. Probably this is the issue. Can you try with latest development release (0.9-b63f5c9) of JupyterHub? Here you can find the all releases: [https://jupyterhub.github.io/helm-chart/#development-releases-jupyterhub](https://jupyterhub.github.io/helm-chart/#development-releases-jupyterhub)

But you have to also go through what is changed from 0.8.2 to 0.9-b63f5c9 (e.g. JupyterHub version is upgraded from 0.9.4 to 1.0.0) and update your configuration.

hey bro, I am following the discussion you guys had above but still do no get that working and the folder /etc/jupyterhub/custom does not appear…Would you mind telling me what command do you use to activate the modified config.yaml? Is it something like this:

$ helm upgrade jhub jupyterhub/jupyterhub --version=0.9-38e1b89 -f config.yaml

Yeah, I used this command with a later version of JupyterHub. I think your version should work though since initContainers were added to that release?

```auto
RELEASE=jhub

helm upgrade $RELEASE jupyterhub/jupyterhub \
  --version=0.9-2d435d6 \
  --values config.yaml

Thank you for your reply! I was using the same config file as yours shown below and in order to simplify, I only define two keys, proxy and hub. Then I was using the command `helm upgrade --install jhub jupyterhub/jupyterhub --namespace jhub --version 0.9-2d435d6 --values config.yaml` to activate this config file.

```auto
proxy:
  secretToken: "5799c72021f34facdf8c09c2f5def77f3117c9edd74d02b6cc04517829fbe878"

hub:
  # Clone custom JupyterHub templates into a volume
  initContainers:
    - name: git-clone-templates
      image: alpine/git
      args:
        - clone
        - --single-branch
        - --branch=master
        - --depth=1
        - --
        - https://github.com/LibreTexts/jupyterhub-templates.git
        - /home/test-templates/
      securityContext:
        runAsUser: 0
      volumeMounts:
        - name: custom-templates
          mountPath: /home/test-templates/
  extraVolumes:
    - name: custom-templates
      emptyDir: {}
  extraVolumeMounts:
    - name: custom-templates
      mountPath: /home/test-templates/

  extraConfig:
    templates: |
      c.JupyterHub.template_paths = ['/home/test-templates/']

```

NOTES:
Thank you for installing JupyterHub!

Your release is named jhub and installed into the namespace jhub.

You can find if the hub and proxy is ready by doing:

 kubectl --namespace=jhub get pod

and watching for both those pods to be in status 'Running'.

You can find the public IP of the JupyterHub by doing:

 kubectl --namespace=jhub get svc proxy-public

It might take a few minutes for it to appear!

Note that this is still an alpha release! If you have questions, feel free to
  1. Read the guide at https://z2jh.jupyter.org
  2. Chat with us at https://gitter.im/jupyterhub/jupyterhub
  3. File issues at https://github.com/jupyterhub/zero-to-jupyterhub-k8s/issues

```

Unfortunately, there is still nothing in `/home/test-templates/` and there is nothing change with login page. BTW, I was using google cloud kubernetes. Any kind suggestions?

Hi everyone,  
I am new to configuring Jhub. I am looking to customize Jhub login on a Kubernetes cluster. I have followed the method described by @bitnik. When I check the hub I see my templates directory with all the files but when I check in jupyterhub\_config.py, I see the template\_paths is not set which may explain why I am not seeing any changes to my login? This is a snippet from the config.py on the hub pod

```auto
 for trait, cfg_key in (
    # Max number of servers that can be spawning at any one time
    ('concurrent_spawn_limit', None),
    # Max number of servers to be running at one time
    ('active_server_limit', None),
    # base url prefix
    ('base_url', None),
    ('allow_named_servers', None),
    ('named_server_limit_per_user', None),
    ('authenticate_prometheus', None),
    ('redirect_to_server', None),
    ('shutdown_on_logout', None),
    *('template_paths', None),*
    ('template_vars', None),
):

```

and this a snippet of my yaml file

```auto
hub:
  initContainers:
    - name: git-clone-templates
      image: alpine/git
      args:
        - clone
        - --single-branch
        - --branch=master
        - --depth=1
        - --
        - https://github.com/me/jupyterhub.git
        - /etc/jupyterhub/custom
      securityContext:
        runAsUser: 0
      volumeMounts:
        - name: custom-templates
          mountPath: /etc/jupyterhub/custom
  extraVolumes:
    - name: custom-templates
      emptyDir: {}
  extraVolumeMounts:
    - name: custom-templates
      mountPath: /etc/jupyterhub/custom
  extraConfig:
    templates: |
      c.JupyterHub.template_paths = ['/etc/jupyterhub/custom']
    jupyterlab: |
      c.Spawner.cmd = ['jupyter-labhub']

```

I greatly appreciate any information that will help me resolve this. Thank you

Hi @LeBoss, do your templates at the root of your repo? I mean the repo that you use in `initContainers`.

> and this a snippet of my yaml file

and could you format the snippets in your post (by adding ````` around them)? so it would be easier to check it.

@bitnik thank you for taking a look. If I understand well, you are asking whether my templates are at the root of my repo? The answer is no, they are one level from the root i.e /jupyterhub/templates/ and my files , including the edited login.html are in the templates sub directory
