Jupyter Lab application features nice Terminas with in-browser terminal shell that support colours, navigation keys, and pretty much all standard features of a terminal application. In this question I mean /lab app, not classic Notebook (/tree) app.

If I launch Jupyter server using this Docker image it works great. I need to build my own image, and preferably not based on that. I do it simply as documented:

I'm running a Kubernetes cluster on AWS using kops. I've mounted an EBS volume onto a container and it is visible from my application but it's read only because my application does not run as root. How can I mount a PersistentVolumeClaim as a user other than root? The VolumeMount does not seem to have any options to control the user, group or file permissions of the mounted path.

Here is my Deployment yaml file:

I want to start a Jupyter notebook in a container. The requirement is that the notebooks that are created in the container should be also available on the host machine. For this I do volume mapping:

We are trying to run a docker entrypoint as root in a docker image used by our jupyterhub for the single user servers. We need root to add a host to access an internal git registry from within a single user jupyter notebook server on a jupyterhub running on K8S by it's domain.

We already tried adding the domain to the /etc/hosts file in the docker image which is loaded for the single user servers by our jupyterhub in a docker-entrypoint script (code can be seen at the bottom).

However we get a permission denied when trying to add the host. The printouts also show why:

Locally, the first whoami shows root , as we expected. On the jupyter notebook started in a pod by our jupyterhub (running on K8s) however, the first printout already shows jovyan.

The same effect can be seen when directly printing out whoami in the entrypoint in the Dockerfile like this:

I am subclassing ContentsManger to create a package to save Notebook data to an OpenStack Swift Store.

I have the basics working - as in I can connect, and starting up a notebook will create a root container in the SwiftStore.

What I need to do now is get the ContentsManager tests to not ERROR, but to Fail (and then, eventually, pass)

Currently I'm getting a No such entity: [Untitled.ipynb] error.... which I kinda half understand - as in there is no such file in my code-base.... but half don't understand - as I can find no reference for it using google-foo!

My test environment

I'm testing my code in a stand-alone environment.

I'm building a Docker image (based on jupyter/base-notebook - so Notebook 5):

FROM jupyter/base-notebook USER root RUN apt-get update && apt-get install -yq --no-install-recommends \ vim \ build-essential \ python3-dev \ less \ && apt-get clean && \ rm -rf /var/lib/apt/lists/* RUN pip install nose pytest pytest-cov python-coveralls COPY . SwiftContentsManager/ WORKDIR SwiftContentsManager RUN pip install -r requirements.txt RUN pip install .

(this creates the docker image, giving me all the stuff a Notebook should have, and then installs my current code into it.)

I start the Docker:
