Image, is a working environment for an instance, we could have pre-built suitable images from public/private registries. We could even build our own images with customization and push to our registry by Image Builder feature. Here is a reference, Custom Image Guideline, describing which official registries we can pull images from and how we build our own ones.
This quickstart shows how we add an pre-built image on PrimeHub for users who can choose it for launching an instance on PrimeHub. If you haven't built any custom image, here is the [quickstart] build image. Here we are going to add that custom image which is installed with
fastai v1 library on PrimeHub.
Let's Add Image
Log in as an administrator and switch to Admin Portal.
Imagesmanagement and click
+ Addfor adding an image spec.
Container image urlwith the url of our custom image. E.g.
Since we put our image on
Google Container Registry(It varies according to your real circumstance.), it requires a pull-secret to pull down the image, we check off
Usage Image Pull Secretand select the right
Globalto make it available to all of users.
Confirmto save the setting.
Now users can select this custom image when launching an JupyterHub instance, once the jupyterhub is launched, we can check the
fastai library version in a notebook.
We, of course, can add an image which is located on public registry without a pull-secret; using url
jupyter/tensorflow-notebook at step 5 instead and leave
Use Image Pull Secret unchecked.
By far, we have created users, groups, instance types and added images, users are ready to launch a JupyterHub instance. Next, we can go further to try custom build images.
