New Open Source Project at the Linux Foundation brings Cloud, Telecom and Network functions providers together in a Kubernetes world

San Francisco—April 12, 2022 Today, the Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced the formation of project Nephio in partnership with Google Cloud and leaders across the telecommunications industry. The Linux Foundation provides a venue for continued ecosystem, developer growth and diversity, as well as collaboration across the open source ecosystems.

Building, managing and deploying scalable 5G networks across multiple edge locations is complex. The Telco industry needs true cloud-native automation to be faster, simpler and easier, while achieving agility and optimization in cloud based deployments. To address these challenges, Google Cloud and the Linux Foundation have founded “Nephio.” The project has support from several founding organizations including Service providers: Airtel, Bell Canada, Elisa, Equinix, Jio, Orange, Rakuten Mobile, TIM, TELUS, Vapor IO, Virgin Media O2, WINDTRE as well as Network Function, Service and Infrastructure Vendors: Aarna Networks, ARM, Casa-systems, DZS, Ericsson, F5, Intel, Juniper, Mavenir, Nokia, Parallel Wireless, VMware.

Cloud Native Principles have come a long way and as we see Cloud Service Providers collaborating with Telecom Service Providers and Enterprises, a new way of simplifying automation of network functions is emerging.

Nephio aims to deliver carrier-grade, simple, open, Kubernetes-based cloud native intent automation and common automation templates that materially simplify the deployment and management of multi-vendor cloud infrastructure and network functions across large scale edge deployments.

Additionally, Nephio will enable faster onboarding of network functions to production including provisioning of underlying cloud infrastructure with a true cloud native approach, and reduce costs of adoption of cloud and network infrastructure.

Classic SysAdmin: Linux 101: Updating Your System

By

-

April 9, 2022

This is a classic article written by Jack Wallen from the Linux.com archives. For more great SysAdmin tips and techniques check out our free intro to Linux course.

Many years ago, when I first began with Linux, installing applications and keeping a system up to date was not an easy feat. In fact, if you wanted to tackle either task you were bound for the command line. For some new users this left their machines outdated or without applications they needed. Of course, at the time, most everyone trying their hand at Linux knew they were getting into something that would require some work. That was simply the way it was. Fortunately times and Linux have changed. Now Linux is exponentially more user friendly – to the point where so much is automatic and point and click – that today’s Linux hardly resembles yesterday’s Linux.

But even though Linux has evolved into the user-friendly operating system it is, there are still some systems that are fundamentally different than their Windows counterparts. So it is always best to understand those systems in order to be able to properly use those system. Within the confines of this article you will learn how to keep your Linux system up to date. In the process you might also learn how to install an application or two.

There is one thing to understand about updating Linux: Not every distribution handles this process in the same fashion. In fact, some distributions are distinctly different down to the type of file types they use for package management.

Ubuntu and Debian use .deb
Fedora, SuSE, and Mandriva use .rpm
Slackware uses .tgz archives which contain pre-built binaries
And of course there is also installing from source or pre-compiled .bin or .package files.

As you can see there are number of possible systems (and the above list is not even close to being all-inclusive). So to make the task of covering this topic less epic, I will cover the Ubuntu and Fedora systems. I will touch on both the GUI as well as the command line tools for handling system updates.

Ubuntu Linux

Ubuntu Linux has become one of the most popular of all the Linux distributions. And through the process of updating a system, you should be able to tell exactly why this is the case. Ubuntu is very user friendly. Ubuntu uses two different tools for system update:

apt-get: Command line tool.
Update Manager: GUI tool.

The Update Manger is a nearly 100% automatic tool. With this tool you will not have to routinely check to see if there are updates available. Instead you will know updates are available because the Update Manager will open on your desktop (see Figure 1) as soon as the updates depending upon their type:

Security updates: Daily
Non-security updates: Weekly

If you want to manually check for updates, you can do this by clicking the Administration sub-menu of the System menu and then selecting the Update Manager entry. When the Update Manager opens click the Check button to see if there are updates available.

Figure 1 shows a listing of updates for a Ubuntu 9.10 installation. As you can see there are both Important Security Updates as well as Recommended Update. If you want to get information about a particular update you can select the update and then click on the Description of update dropdown.

In order to update the packages follow these steps:

Check the updates you want to install. By default all updates are selected.
Click the Install Updates button.
Enter your user (sudo) password.
Click OK.

The updates will proceed and you can continue on with¬† your work. Now some updates may require either you to log out of your desktop and log back in, or to reboot the machine. There are is a new tool in development (Ksplice) that allow even the update of a kernel to not require a reboot.
Once all of the updates are complete the Update Manage main window will return reporting that Your system is up to date.

Now let’s take a look at the command line tools for updating your system. The Ubuntu package management system is called apt. Apt is a very powerful tool that can completely manage your systems packages via command line. Using the command line tool has one drawback – in order to check to see if you have updates, you have to run it manually. Let’s take a look at how to update your system with the help of Apt. Follow these steps:

Open up a terminal window.
Issue the command sudo apt-get upgrade.
Enter your user’s password.
Look over the list of available updates (see Figure 2) and decide if you want to go through with the entire upgrade.
To accept all updates click the ‘y’ key (no quotes) and hit Enter.
Watch as the update happens.

That’s it. Your system is now up to date. Let’s take a look at how the same process happens on Fedora (Fedora 12 to be exact).

Fedora Linux

Fedora is a direct descendant of Red Hat Linux, so it is the beneficiary of the Red Hat Package Management system (rpm). Like Ubuntu, Fedora can be upgraded by:

yum: Command line tool.
GNOME (or KDE) PackageKit: GUI tool.

Depending upon your desktop, you will either use the GNOME or the KDE front-end for PackageKit. In order to open up this tool you simply go to the Administration sub-menu of the System menu and select the Software Update entry.¬† When the tool opens (see Figure 3) you will see the list of updates. To get information about a particular update all you need to do is to select a specific package and the information will be displayed in the bottom pane.

To go ahead with the update click the Install Updates button. As the process happens a progress bar will indicate where GNOME (or KDE) PackageKit is in the steps. The steps are:

Resolving dependencies.
Downloading packages.
Testing changes.
Installing updates.

When the process is complete, GNOME (or KDE) PackageKit will report that your system is update. Click the OK button when prompted.

Now let’s take a look at upgrading Fedora via the command line. As stated earlier, this is done with the help of the yum command. In order to take care of this, follow these steps:

Open up a terminal window (Do this by going to the System Tools sub-menu of the Applications menu and select Terminal).
Enter the su command to change to the super user.
Type your super user password and hit Enter.
Issue the command yum update and yum will check to see what packages are available for update.
Look through the listing of updates (see Figure 4).

Final Thoughts

Granted only two distributions were touched on here, but this should illustrate how easily a Linux installation is updated. Although the tools might not be universal, the concepts are. Whether you are using Ubuntu, OpenSuSE, Slackware, Fedora, Mandriva, or anything in-between, the above illustrations should help you through updating just about any Linux distribution. And hopefully this tutorial helps to show you just how user-friendly the Linux operating system has become.

Here at The Linux Foundation’s blog, we share content from our projects, such as this article by Joel Hans from the Cloud Native Computing Foundation’s blog.

The telecommunications industry is the backbone of today’s increasingly-digital economies, but it faces a difficult new challenge in evolving to meet modern infrastructure practices. How did telecommunications get itself into this situation? Because the risks of incidents or downtime are so severe, the industry has focused almost exclusively on system designs that minimize risk and maximize reliability. That’s fantastic for mission-critical services, whether public air traffic control or private high-speed banking, but it emphasizes stability over productivity and the adoption of new technologies that might make their operations more resilient and performant.

Telecommunications is playing catch-up on cloud native technology, and the downstream effects are starting to show. These organizations are now behind the times on the de facto choices for enterprise and IT, which means they’re less likely to recruit the top-tier engineering talent they need. In increasingly competitive landscapes, they need to escalate productivity and deploy new telephony platforms to market faster, not get quagmired in old custom solutions built in-house.

To make that leap from internally-trusted to industry-trusted tooling, telecommunications organizations need confidence that they’re on track to properly evolve their virtual network function (VNF) infrastructure to enable cloud native functions using Kubernetes. That’s where CNCF aims to help.

Enter the CNF Test Suite for telecommunications

A cloud native network function (CNF) is an application that implements or facilitates network functionality in a cloud native way, developed using standardized principles and consisting of at least one microservice.

And the CNF Test Suite (cncf/cnf-testsuite) is an open source test suite for telcos to know exactly how cloud native their CNFs are. It’s designed for telecommunications developers and network operators, building with Kubernetes and other cloud native technology, to validate how well they’re following cloud native principles and best practices, like immutable infrastructure, declarative APIs, and a “repeatable deployment process.”

The CNCF is bringing together the Telecom User Group (TUG) and the Cloud Native Network Function Working Group (CNF WG) to implement the CNF Test Suite, which helps telco developers and ops teams build faster feedback loops thanks to the suite’s flexible testing and optimized execution time. Because it can be integrated into any CI/CD pipeline, whether in development or pre-production checks, or run as a standalone test for a single CNF, telecommunications development teams get at-a-glance understanding of how their new deployments align with the cloud native ecosystem, including CNCF-hosted projects, technologies, and concepts.

It’s a powerful answer to a difficult question: How cloud native are we?

The CNF Test Suite leverages 10 CNCF-hosted projects and several open source tools. A modified version of CoreDNS is used as an example CNF for end users to get familiar with the test suite in five steps, and Prometheus is utilized in an observability test to check the best practice for CNFs to actively expose metrics. And it packages other upstream tools, like OPA Gatekeeper, Helm linter, and Promtool to make installation, configuration, and versioning repeatable. The CNF Test Suite team is also grateful to contributions from Kyverno on security tests, LitmusChaos for resilience tests, and Kubescope for security policies.

The minimal install for the CNF Test Suite requires only a running Kubernetes cluster, kubectl, curl, and helm, and even supports running CNF tests on air-gapped machines or those who might need to self-host the image repositories. Once installed, you can use an example CNF or bring your own—all you need is to supply the .yml file and run `cnf-testsuite all` to run all the available tests. There’s even a quick five-step process for deploying the suite and getting recommendations in less than 15 minutes.

What the CNF Test Suite covers and why

At the start of 2022, the CNF Test Suite can run approximately 60 workload tests, which are segmented into 7 different categories.

Compatibility, Installability & Upgradability: CNFs should work with any Certified Kubernetes product and any CNI-compatible network that meet their functionality requirements while using standard, in-band deployment tools such as Helm (version 3) charts. The CNF Test Suite checks whether the CNF can be horizontally and vertically scaled using `kubectl` to ensure it can leverage Kubernetes’ built-in functionality.

Microservice: The CNF should be developed and delivered as a microservice for improved agility, or the development time required between deployments. Agile organizations can deploy new features more frequently or allow multiple teams to safely deploy patches based on their functional area, like fixing security vulnerabilities, without having to sync with other teams first.

State: A cloud native infrastructure should be immutable, environmentally-agnostic, and resilient to node failure, which means properly managing configuration, persistent data, and state. A CNF’s configuration should be stateless, stored in a custom resource definition or a separate database over local storage, with any persistent data managed by StatefulSets. Separate stateful and stateless information makes for infrastructure that’s easily reproduced, consistent, disposable, and always deployed in a repeatable way.

Reliability, Resilience & Availability: Reliability in telco infrastructure is the same as standard IT—it needs to be highly secure and reliable and support ultra-low latencies. Cloud native best practices try to reduce mean time between failure (MTBF) by relying on redundant subcomponents with higher serviceability (mean time to recover (MTTR)), and then testing those assumptions through chaos engineering and self-healing configurations. The Test Suite uses a type of chaos testing to ensure CNFs are resilient to the inevitable failures of public cloud environments or issues on an orchestrator level, such as what happens when pods are unexpectedly deleted or run out of computing resources. These tests ensure CNFs meet the telco industry’s standards for reliability on non-carrier-grade shared cloud hardware/software platforms.

Observability & Diagnostics: Each piece of production cloud native infrastructure must make its internal states observable through metrics, tracing, and logging. The CNF Test suite looks for compatibility with Fluentd, Jaeger, Promtool, Prometheus, and OpenMetrics, which help DevOps or SRE teams maintain, debug, and gather insights about the health of their production environments, which must be versioned, maintained in source control, and altered only through deployment pipelines.

Security: Cloud native security requires attention from experts at the operating system, container runtime, orchestration, application, and cloud platform levels. While many of these fall outside the scope of the CNF Test Suite, it still validates whether containers are isolated from one another and the host, do not allow privilege escalation, have defined resource limits, and are verified against common CVEs.

Configuration: Teams should manage a CNF’s configuration in a declarative manner—using ConfigMaps, Operators, or other declarative interfaces—to design the desired outcome, not how to achieve said outcome. Declarative configuration doesn’t have to be executed to be understood, making it far less prone to error than imperative configuration or even the most well-maintained sequences of `kubectl` commands.

After deploying numerous tests in each category, the CNF Test Suite outputs flexible scoring and suggestions for remediation for each category (or one category if you chose that in the CLI), giving you practical next steps on improving your CNF to better follow cloud native best practices. It’s a powerful—and still growing—solution for the telecommunications industry to embrace the cloud native in a way that’s controllable, observable, and validated by all the expertise under the CNCF umbrella.

What’s next for the CNF Test Suite?

The Test Suite initiative will continue to work closely with the Telecom User Group (TUG) and the Cloud Native Network Function Working Group (CNF WG), collecting feedback based on real-world use cases and evolving the project. As the CNF WG publishes more recommended practices for cloud native telcos, the CNF Test Suite team will add more tests to validate each.

In fact, v0.26.0, released on February 25, 2022, includes six new workload tests, bug fixes, and improved documentation around platform tests. If you’d like to get involved and shape the future of the CNF Test Suite, there are already several ways to provide feedback or contribute code, documentation, or example CNFs:

Looking ahead: The CNF Certification Program

The CNF Test Suite is just the first exciting step in the upcoming Cloud Native Network Function (CNF) Certification Program. We’re looking forward to making the CNF Test Suite the de facto tool for network equipment providers and CNF development teams to prove—and then certify—that they’re adopting cloud native best practices in new products and services.

The wins for the telecommunications industry are clear:

Providers get verification that their cloud native applications and architectures adhere to cloud native best practices.
Their customers get verification that the cloud native services or networks they’re procuring are actually cloud native.

And they both get even better reliability, reduced risk, and lowered capital/operating costs.

We’re planning on supporting any product that runs in a certified Kubernetes environment to make sure organizations build CNFs that are compatible with any major public cloud providers or on-premises environments. We haven’t yet published the certification requirements, but they will be similar to the k8s-conformance process, where you can submit results via pull request and receive updates on your certification process over email.

As the CNF Certification Program develops, both the TUG and CNF-WG will engage with organizations that use the Test Suite heavily to make improvements and stay up-to-date on the latest cloud native best practices. We’re excited to see how the telecommunications industry evolves by adopting more cloud native principles, like loosely-coupled systems and immutability, and gathering proof of their hard work via the CNF Test Suite. That’s how we ensure a complex and essential industry makes the right next steps away toward the best technology infrastructure has to offer—without sacrificing an inch on reliability.

To take the next steps with the CNF Test Suite and prepare your organization for the upcoming CNF Certification Program, schedule a personalized CNF Test Suite demo or attend Cloud Native Telco Day, a co-located Event at KubeCon + CloudNativeCon Europe 2022 on May 16, 2022.
