Don’t miss these essential tips to keep your system optimized and secure! https://journalctl.org/post/compliance-operator/ Sat, 22 Jun 2024 10:29:34 -0400 https://journalctl.org/post/compliance-operator/ Introduction to the Compliance Operator The OpenShift Compliance Operator is all about keeping your OpenShift cluster secure and in line with governance policies. It does this by scanning both the OpenShift Platform 4 (ocp4) and Red Hat Core OS 4 (RHCOS4). Now, let’s break down the types of compliance checks it can handle: Platform (Cluster) Related Checks: These checks use the OpenShift API to make sure everything is shipshape. Node Related Checks: These scans take a closer look at the filesystem of each node. https://journalctl.org/post/rhacs/ Thu, 14 Mar 2024 08:59:28 -0400 https://journalctl.org/post/rhacs/ Recently, I have been working on Red Hat Advanced Cluster Security (RHACS) to identify security vulnerabilities and implementing cluster hardening rules within OpenShift clusters. Inspired by my experiences, I decided to share my insights through this blog post. Join me as we delve into the world of RHACS and explore its functionality. Introduction to RHACS Red Hat Advanced Cluster Security (RHACS) is the downstream project for the upstream Stackrox project. In other words, enhancements to the source code are initially made in Stackrox, and then they undergo testing and packaging to become part of RHACS. https://journalctl.org/post/renovate/ Thu, 21 Dec 2023 11:46:02 -0400 https://journalctl.org/post/renovate/ Open Source Software (OSS) projects have been distributed in packages for decades. Using packages allows developers to focus on new feature implementation. Major software distributions, such as Fedora, Debian, etc, typically consist of thousands of packages. These packages depend on each other to perform tasks efficiently by avoiding code duplication. The inter-dependence amongst the packages creates a software supply chain. Examples of software security principles such as using software binaries that are signed by the software vendor, keeping binaries regularly updated, and constantly monitoring software behaviour are general to any software system. https://journalctl.org/post/lean-container-images/ Sat, 28 Oct 2023 12:00:59 -0500 https://journalctl.org/post/lean-container-images/ Need for slimming down containers OpenShift, an enterprise-ready Kubernetes platform, offers a multitude of benefits. One such advantage is the Source-to-Image (S2I) build strategy, that simplifies the process of converting source code into deployable container images. This strategy enables developers to build container images without the need to define a container file explicitly. OpenShift clones the application’s source code into a builder image that utilizes builder scripts, ultimately generating a container image deployable within the cluster. https://journalctl.org/post/systemd-containers/ Tue, 18 Jul 2023 15:02:42 -0400 https://journalctl.org/post/systemd-containers/ To reduce the need for manual intervention, use systemd to manage container-based applications on a health check. https://journalctl.org/post/ossna2023/ Fri, 19 May 2023 08:59:28 -0400 https://journalctl.org/post/ossna2023/ From May 10th to 12th, the Vancouver Convention Center came alive with the Open Source Summit North America, a three-day event that brought together open source software enthusiasts from around the world. With a focus on exploring the newest trends and embracing opportunities in the ever-changing field of open source technology, this premier conference drew over two thousand attendees. In this blog post, we’ll dive into my own presentation and its key points, share some highlights from the inspiring talks I attended, and take a closer look at the exciting conversations and new discoveries that unfolded at the Red Hat booth. https://journalctl.org/about/ Mon, 01 Jan 0001 00:00:00 +0000 https://journalctl.org/about/ Bio I am a skilled professional with a strong background in Linux system administration, and software engineering. I hold an MSc. in Computer Science from Queen’s University, where my research focused on software supply chain security. With expertise in DevOps tools such as Ansible, Docker, Kubernetes, OpenShift, Puppet, Terraform, and Vagrant, I excel in automating software systems and infrastructure. I consistently deliver high-quality code, implement critical features, and actively contribute to open-source projects.
