  • AI Meets Kubernetes: Install JupyterHub with Rancher
  • By their nature, AI and ML are computation hungry workloads. They require best-in-class distributed computing environments to thrive. AI and ML present a perfect use case for Kubernetes, the distributed computing platform engineered at Google to run their massive workloads.

    What is JupyterHub? JupyterHub is a multi-user data exploration tool that is often key for data science and machine learning research and development. It provides engineers, scientists, researchers and students the computational power of a cloud or data center while still being as easy to use as a local development environment. Essentially, JupyterHub gives users access to computational environments and resources without burdening them with installation and maintenance tasks.

    Users can work in their workspaces on shared resources, which can be managed efficiently by system administrators. Applying computing resources to a workload is easy because of its declarative as opposed to imperative design and its discovery-based approach to addressing servers.

    Kubernetes makes migrating that workload between physical infrastructure more feasible. At the time of publication, the stable release of Kubernetes is 1. For purposes of demonstration, we can use the experimental NFS provisioner included in our catalog to provide persistent storage.

    Navigate to the App Catalog and select Launch. Then search for NFS provisioner. Leave the defaults as they are and click Launch at the bottom of the screen. If you already have a persistent storage solution, you can use that as well. Navigating to the Rancher App Catalog Searching for the NFS provisioner for persistent storage Launching the NFS provisioner Now that we have a storage provisioner and a default storage class defined, we can move on to deploying the application components.

    See the helm docs for installing the helm 3 client on your computer. Be sure to add the repo to the Rancher catalog. Before we use helm, we need to create a namespace for this application.

    There you can create a new namespace for JupyterHub. Note of this name as we are going to use it in a bit. Creating a namespace Next, we can add the Helm repo for the JupyterHub chart we are going to use. It will take some time, but eventually you should be able to access the UI via the hostname you set earlier.

    You can check the status by going to the workloads tab in the Rancher UI as well. When we try the hostname we set in a browser, it should show the following login screen: Hostname login screen One issue at the time of this writing is a change made in Kubernetes 1. There is an issue tracking this. So, to log in, any valid Linux user on your systems will work.

    When we login, we should be able to start creating new notebooks: Jupyter login screen Creating new notebooks Alternatively, you can check out the other auth options you might want to configure.

    For instance, you could use GitHub auth to allow users to login and create notebooks based on their Github ID. Once you choose an auth provider, update the config.

    Conclusion In this article, we showed you how you can create scalable workspaces for data science and machine learning development by installing JupyterHub using Rancher. Enjoy the journey and let us know how it goes!

    They also shipped with Android 12 out-of-the-box, and if you take a look at the kernel sources, you can find Linux kernel 5. But even on small teams, it is possible to compete with big players and attract and hire top talent. These days, employees are prioritizing flexibility.

    Having proven that they are just as productive if not more working from home, many folks are unwilling to go back to in-person full-time. Building out flexible work policies, focusing on upskilling, and offering competitive benefits should be a part of your plan to create a work environment tailored to the employee.

    But how do you get the right candidates in the door? Here are five ways to attract top talent that might also land your organization on the Best Places to Work list! Normalize web services with Camel K and AtlasMap, Part 1 This two-part series walks through a simple way to normalize and connect services through Camel K, a part of the Apache Camel project.

    The scenario in this article addresses a common problem today: Organizations find themselves with a menagerie of different services using different APIs, perhaps because of partnerships or acquisitions. Apache Camel makes it easy to harmonize and normalize the APIs, and its Camel K extension brings Apache Camel's operations to Kubernetes, allowing containers to expose these endpoints.

    In this article, we will focus on the benefits of choosing this framework and provide an overview of our base integration flow using Camel K to normalize a backend API. Part 2 will show you how to implement the integration flow step-by-step. We'll also cover how to simplify data mapping with AtlasMap. Change deployments on the fly in OpenShift 4. In OpenShift 4. The form can also prompt you with existing values where appropriate. Keep reading to learn why the new form-based editor is both an exciting feature and a double-edged sword.

    This article highlights some of the great efforts undertaken in the community around creating interesting applications for PipeWire in an interview with the maintainers of two of the most popular applications built with PipeWire. The distribution has now integrated Keylime, an open source project for doing remote attestation with TPMs. If you follow the news about Windows 11, you are aware of what is a TPM. You can find the TPM already soldered in the mainboard of your computer, but they can also be found as a service in the firmware, or inside your CPU.

    This co-processor can be used for many tasks related with security. For example, we can use it to generate symmetric and asymmetric keys, encrypt some memory blocks not too big, as they are a bit slow , or to as storage for keys that can be used only for us or applications that have permissions.

Played on Linux with the Steam Play Proton compatibility layer, it's mostly smooth Warhammer melee action. Currently with Proton Experimental Proton GE did not work at all the main issue is small videos not loading, like the tutorial videos but it doesn't really detract from the overall experience, thankfully as the developer also explains with text below each video.

    As with any newer game running through Proton, there was some stuttering while building up a shader cache too, hopefully as more people play it this will be less of an issue for Linux VR gamers since there will be shaders to download from Steam. There are no goodies in the Warhammer 40, universe. Diving Into China's Draconian Video Game Regulations Even if you're against these particular regulations what are you, in favor of fun, you monster? For instance, banning games that are entirely about simulated sexual assault, or calling out tech and gaming companies for infringing on users' rights and preventing them from building monopolies.

    This year he has taken to getting that code cleaned up and working against the latest upstream state of the kernel and other basic changes. While Xen is not as popular as it once was, there still are users interested in seeing this USB device support for Xen para-virtualized use-cases. A Baidu engineer posted a set of patches implementing the Zhouyi AI accelerator support in a new "zynpu" driver for the kernel.

    The more than five thousand lines of code provide this initial support. Dave Airlie: video decode: crossing the streams I was interested in how much work a vaapi on top of vulkan video proof of concept would be. My main reason for being interested is actually video encoding, there is no good vulkan video encoding demo yet, and I'm not experienced enough in the area to write one, but I can hack stuff. I think it is probably easier to hack a vaapi encode to vulkan video encode than write a demo app myself.

    With that in mind I decided to see what decode would look like first. I talked to Mike B most famous zink author before he left for holidays, then I ignored everything he told me and wrote a super hack. Airlie explained today that he has been investigating the possibility of VA-API on top of Vulkan Video, namely on the video encode side for not having any good software out there at the moment exercising the Vulkan Video encode extensions.

    Android Leftovers.

    This level of flexibility enables you to use the tools of your choice, including Jupyter Notebooks and a python stack, and control access to resources and the environment. What are the Use Cases of JupyterHub? There is a wide range of applications for JupyterHub. It is used by large data centers providing computing resources to data scientists, major research labs, large universities serving data science students and researchers, companies with extensive data science operations, and online communities that promote collaborative data science and machine learning.

    JupyterHub is usually used to enable collaboration between small and large teams: Small teams—use JupyterHub to enable sharing interactive computing resources and analytics. Small teams include research labs, data science teams, or any collaborative project. Large teams—use JupyterHub for providing multiple users with access to corporate resources like data, hardware, and analytics programs.

    Lard teams include any large group of remote users like departments and large classes.

    JupyterHub

    JupyterHub Features and Capabilities JupyterHub provides the following key capabilities: Sets up a Jupyter Notebook or JupyterLab environment for up to tens of thousands of users—supports Kubernetes for large-scale deployments. Supports many different languages, environments, and user interfaces, with a variety of Jupyter kernels developed by the community see the list of available kerners.

    You can deliver one or more existing kernels to JupyterHub users, or develop your own. Provides pluggable authentication, enabling flexible authentication for some or all users, using several authentication protocols including OAuth and GitHub.

    Scales up by sharing the same server with multiple users, or running multiple isolated containers. Can be deployed on any infrastructure, including public cloud providers, virtual machines, or locally on an on-premise laptop or server. To achieve this, the architecture uses the following three main subsystems: Hub—designed to manage user accounts and authentication.

    The hub uses a Spawner when coordinating single-user notebook servers. Proxy—serves as the public-facing component. Single-user notebook server—an object called Spawner starts a single-user notebook when a user logs in.

    Install Jupyter Notebook 4 or higher. The Hub and the proxy The Hub is responsible for handling logins and spawning single-user notebooks servers.

    When a user attempts to gain access, the Hub spawns a proxy based on the JupyterHub configuration.

    The proxy can then forward all requests to the Hub. Only the proxy is allowed to listen on a public interface. Types of authenticators There are several authenticators available for controlling access to JupyterHub. PAM is the default authenticator. It uses the user accounts that are located on the same server running JupyterHub. PAM requires creating a user account per each user. Other authenticators can enable users to log in using single-sign-on.

    Spawners A spawner creates a notebook server for each user, and defines how that notebook will be configured. By default, a spawner starts a server on the machine currently running the system username. Alternatively, you can start the notebook server within a separate container. You can use orchestrators like Docker when you opt to use containers.

    Note that if you want to allow multiple users to log in to the Hub Server, you need to start JupyterHub with root privileges, as follows: sudo jupyterhub JupyterHub Tutorial 2: Deploying Using Kubernetes For larger deployments, you can deploy JupyterHub via Kubernetes, the popular container orchestrator. The instructions and code below are abbreviated from the full Zero to JupyterHub Kubernetes tutorial.

    Related content: read our guide to Kubernetes architecture for machine learning Prepare Configuration File Start by preparing a configuration file called config.

    This includes several values used to configure the JupyterHub Helm chart. You can use this chart to deploy a working version of JupyterHub to Kubernetes. You can keep the Helm values as default, but there is one value that is mandatory to set—the secretToken value which is used as your security token.
