  • Queensland government looks to open source for single sign-on project

    Red Hat Single Sign-On, which is based on the open source Keycloak project, and the Apollo GraphQL API Gateway platform will be the two key software components underpinning a Queensland effort to deliver a single login for access to online government services.

    Queensland is implementing single sign-on capabilities for state government services, including ‘tell us once’ capabilities that will allow basic personal details of individuals to be, where consent is given by an individual, shared between departments and agencies.

  • Red Hat Releases Open Source Project Quay Container Registry
  • Red Hat open sources Project Quay container registry

    Yesterday, Red Hat introduced the open source Project Quay container registry, which is the upstream project representing the code that powers Red Hat Quay and Quay.io. Open-sourced as a Red Hat commitment, Project Quay “represents the culmination of years of work around the Quay container registry since 2013 by CoreOS, and now Red Hat,” the official post reads.

    Red Hat Quay container image registry provides storage and enables users to build, distribute, and deploy containers. It will also help users to gain more security over their image repositories with automation, authentication, and authorization systems. It is compatible with most container environments and orchestration platforms and is also available as a hosted service or on-premises.

  • Red Hat declares Quay code open

    Red Hat has open sourced the code behind Project Quay, the six year old container registry it inherited through its purchase of CoreOS.

    The code in question powers both Red Hat Quay and Quay.IO, and also includes the Clair open source security project which was developed by the Quay team, and integrated with the registry back in 2015.

    In the blog post announcing the move, Red Hat principal software engineer – and CoreOS alumnus – Joey Schorr, wrote, “We believe together the projects will benefit the cloud-native community to lower the barrier to innovation around containers, helping to make containers more secure and accessible.”

  • New Open Source Offerings Simplify Securing Kubernetes

    In advance of the upcoming KubeCon 2019 (CyberArk booth S55), the flagship event for all things Kubernetes and Cloud Native Computing Foundation, CyberArk is adding several new Kubernetes offerings to its open source portfolio to improve the security of application containers within Kubernetes clusters running enterprise workloads.

  • Java Applications Go Cloud-Native with Open-Source Quarkus Framework

    "With Quarkus, Java developers are able to continue to work in Java, the language they are proficient in, even when they are working with new, cloud-native technologies," John Clingan, senior principal product manager of middleware at Red Hat, told IT Pro Today. "With memory utilization measured in 10s of MB and startup time measured in 10s of milliseconds, Quarkus enables organizations to continue with their significant Java investments for both microservices and serverless."

    Many organizations have been considering alternative runtimes to Java, like Node.js and Go, due to high memory utilization of Java applications, according to Clingan. In addition, Java’s startup times are generally too slow to be an effective solution for serverless environments. As such, Clingan said that even if an organization decided to stick with Java for microservices, it would be forced to switch to an alternative runtime for serverless, or functions-as-a-service (FaaS), deployment.

  • Styra Secures $14M in Funding Led by Accel to Expand Open Source and Commercial Solutions for Kubernetes/Cloud-native Security

    New technology—like Kubernetes, Containers, ServiceMesh, and CICD Automation—speed application delivery and development. However, they lack a common framework for authorization to determine where access should be allowed, and where it should be denied. Styra’s commercial and open source solutions—purpose-built for the scale of cloud-native development—provide this authorization layer to mitigate risk across cloud application components, as well as the infrastructure they are built upon.

The Secrets of Docker Secrets

Filed under
Server
HowTos

Most web apps need login information of some kind, and it is a bad idea to put them in your source code where it gets saved to a git repository that everyone can see. Usually these are handled by environment variables, but Docker has come up with what they call Docker secrets. The idea is deceptively simple in retrospect. While you figure it out it is arcane and difficult to parse what is going on.

Essentially the secrets function create in memory files in the docker image that contain the secret data. The data can come from files, or a Docker swarm.

The first thing to know is that the application running in the docker image needs to be written to take advantage of the Docker secrets function. Instead of getting the password from an environment variable, it would get the password from the file system at /run/secrets/secretname. Not all images available use this functionality. If they don't describe how to use Docker secrets, the won't work. The files will be created in the image, but the application won't read them.

  • Knative at 1: New Changes, New Opportunities

    This summer marked the one-year anniversary of Knative, an open-source project that provides the fundamental building blocks for serverless workloads in Kubernetes. In its relatively short life (so far), Knative is already delivering on its promise to boost organizations’ ability to leverage serverless and FaaS (functions as a service).

    Knative isn’t the only serverless offering for Kubernetes, but it has become a de-facto standard because it arguably has a richer set of features and can be integrated more smoothly than the competition. And the Knative project continues to evolve to address businesses’ changing needs. In the last year alone, the platform has seen many improvements, giving organizations looking to expand their use of Kubernetes through serverless new choices, new considerations and new opportunities.

  • Redis Labs Leverages Kubernetes to Automate Database Recovery

    Redis Labs today announced it has enhanced the Operator software for deploying its database on Kubernetes clusters to include an automatic cluster recovery that enables customers to manage a stateful service as if it were stateless.

    Announced at Redis Day, the latest version of Kubernetes Operator for Redis Enterprise makes it possible to spin up a new instance of a Redis database in minutes.

    Howard Ting, chief marketing officer for Redis Labs, says as Kubernetes has continued to gain traction, it became apparent that IT organizations need tools to provision Redis Enterprise for Kubernetes clusters. That requirement led Redis Labs to embrace Operator software for Kubernetes developed by CoreOS, which has since been acquired by Red Hat. IT teams can either opt to recover databases manually using Kubernetes Operator or configure the tool to recover databases automatically anytime a database goes offline. In either case, he says, all datasets are loaded and balanced across the cluster without any need for manual workflows.

The 6 Best PostgreSQL Monitoring Tools in 2019

Filed under
Server
Software

The main point of monitoring PostgreSQL databases is to ensure that the data they hold is available whenever it is needed and that their performance—i.e. how fast they respond to queries—remains within acceptable parameters. Today, we’re having a look at a few of the best PostgreSQL monitoring tools.

We’ll start off by briefly explaining what PostgreSQL is, where it is coming from and how it came to be. After all, it can only help to know a bit more about what we’re trying to monitor. Then, we’ll specifically discuss the monitoring of PostgreSQL databases. We’ll learn how database servers should be considered in their entirety and that the best monitoring will not only include the actual database software but also the underlying operating system and hardware. We’ll then get to the core of this post as we introduce the best PostgreSQL monitoring tools we could find and give you a brief review of each one.

  • 4 container usage takeaways from the 2019 Sysdig report

    You probably already knew that most of the containers created by developers are disposable, but did you realize that half of them are only around for less than five minutes? That and other fascinating details are available in the latest annual container report from Sysdig, a container security and orchestration vendor.

    This is the company’s third such report. The results are obtained from their own instrumentation collected from a five-day period last month of the more than 2 million containers used by their own customers. This means the results could be somewhat skewed toward more experienced container developers.

    Nevertheless, the report merits some scrutiny. Here are four important takeaways.

  • CNCF Adopts Longhorn Storage Project from Rancher Labs

    Based on 30,000 lines of Go code employed to create separate engine and management plane, Longhorn is significantly lighter than traditional storage software because it builds on existing Linux storage primitives, Liang says. It also doesn’t require a dedicated storage administrator to deploy and manage. It’s designed from the ground up to be used by the same team managing the Kubernetes cluster, he notes, adding modern storage hardware such as solid-state drives (SSDs) and NVMe backplanes made it easier to build Longhorn without compromising performance.

    While some applications might want to access block storage directly, Liang says Rancher Labs expects most organizations will layer a file system on top of Longhorn to access various forms of persistent storage.

  • Setup Complete Qt SDK on Ubuntu Eoan Ermine

    Qt Software Development Kit (Qt SDK) includes Qt Creator IDE & Qt Framework Libraries with Full Code Examples among other things. On Ubuntu 19.10, if you want to develop GUI applications with Qt, you need to install that Qt SDK first with a C++ compiler. Installing it on 19.10 is slightly different to different to 18.04 as this involves configuring GNU GCC C++ compiler on 19.10. After setup, you will have a ready, complete Qt SDK with Creator, Designer, Linguist, and Assistant works with G++ compiler. I hope this will be useful for you all. Happy hacking!

  • Red Hat Advances Java on Kubernetes Project

    Red Hat today achieved a 1.0 milestone in its efforts to make an instance of Java available for Kubernetes via the open source Quarkus project.

    Mark Little, vice president of engineering for Red Hat, says Quarkus 1.0 advances an effort to create a more efficient means for building and deploying Java applications on Kubernetes by reducing the size of the Java virtual machine (JVM). The JVM used today assumed that the JVM would include the code required to write once and deploy anywhere. However, in a container environment, portability issues are addressed by Docker containers and Kubernetes. That creates an opportunity to shrink the JVM in a way that will make Java applications running on Kubernetes run faster, notes Little.
