  • A New Method of Containment: IBM Nabla Containers

    In the previous post about Containers and Cloud Security, I noted that most of the tenants of a Cloud Service Provider (CSP) could safely not worry about the Horizontal Attack Profile (HAP) and leave the CSP to manage the risk. However, there is a small category of jobs (mostly in the financial and allied industries) where the damage done by a Horizontal Breach of the container cannot be adequately compensated by contractual remedies. For these cases, a team at IBM research has been looking at ways of reducing the HAP with a view to making containers more secure than hypervisors. For the impatient, the full open source release of the Nabla Containers technology is here and here, but for the more patient, let me explain what we did and why. We’ll have a follow on post about the measurement methodology for the HAP and how we proved better containment than even hypervisor solutions.

    The essence of the quest is a sandbox that emulates the interface between the runtime and the kernel (usually dubbed the syscall interface) with as little code as possible and a very narrow interface into the kernel itself.

  • Kubernetes 1.12 Arrives With TLS and Better Cloud Integrations

    The Kubernetes project has been hurtling at breakneck speed towards the boring. As the popular open source container orchestration platform has matured, it’s been the boring features which have come front and center, many of which focus on stability and reliability. For the Kubernetes 1.12 release on Thursday, those working on the project and on the various special interest groups (SIGs) initially laid out over 60 proposed features. A little over half of those made it to the final release, with many more being pushed back or delayed, as usual.

    Amongst the changes that made it into this release are such additions as the general availability of TLS bootstrapping, the ability to use the Kubernetes API to restore a volume from a volume snapshot data source, a newly beta version of the KubeletPluginsWatcher, and some groundwork which is being put in place to solve scheduling challenges that confront large clusters

  • Platform9 Open-Sources etcdadm, Enabling the Kubernetes Community to Easily Create and Manage Secure etcd Clusters, Anywhere

    Platform9, the leader in SaaS-managed hybrid clouds, today announced etcdadm – a new open source project available under the Apache v2.0 license...

  • Platform9 Open Sources Its Kubernetes Etcd Support Tool

    Platform9 pushed its etcdadm support tool out into the open source community via GitHub in an effort to generate momentum behind automating the configuration, deployment, and management of etcd clusters used by Kubernetes to store control plane information. Those tasks are currently either part of more broadly-focused efforts put on the shoulders of a Kubernetes user, or cobbled together by developers.

    Etcd is the primary storage location for Kubernetes and needs to be established before Kubernetes can be run on a system. Arun Sriraman, Kubernetes technical lead manager at Platform9, explained in a video that etcd is the “backbone for Kubernetes storage.”

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
