devopscube curates Docker and K8s
- DevOpsCube’s latest learning push centered on Docker and Kubernetes basics, pointing readers to hands-on guides, certification prep, and project-based study paths. - Its public GitHub profile says DevOpsCube maintains 500-plus guides, a Kubernetes learning path, a Docker course, and Linux Foundation coupon resources. - The links fit a broader shift toward portfolio-first DevOps training and certification prep.

Docker packages an app with its dependencies so it runs the same way everywhere, while Kubernetes schedules and scales those containers across servers. DevOpsCube is packaging both topics as a practical learning stack. (docker.com) (github.com) DevOpsCube’s site says it serves 250,000-plus community members and 19,500-plus newsletter subscribers with weekly deep dives, tutorials, roadmaps, and certification guides. Its homepage currently highlights Docker, Kubernetes, Argo CD, GitHub Actions, and Amazon Web Services content. (devopscube.com) Its GitHub profile describes the project as a “practical learning community” for DevOps, platform, and site reliability engineers, with repositories for Kubernetes projects, a Kubernetes learning path, DevOps interview prep, and Linux Foundation coupon codes. The same profile advertises a structured Docker course and says the blog has more than 500 in-depth guides. (github.com) That mix reflects how DevOps hiring has shifted toward proof of hands-on work. A Docker image build pipeline, a Kubernetes deployment, and a GitOps workflow with Argo CD are the kinds of artifacts recruiters can verify in a repository. (devopscube.com) (github.com) The technical split is straightforward: Docker builds the container image, GitHub Actions automates tests and image publishing, and Argo CD watches a Git repository and syncs changes into a Kubernetes cluster. Spacelift’s December 2025 guide describes GitHub Actions as the delivery pipeline around Kubernetes deployments, while DevOpsCube’s March 2026 post focuses on image build and promotion. (spacelift.io) (devopscube.com) For beginners, Docker is usually the first step because it solves the “works on my machine” problem by bundling code, runtime, and dependencies into a portable container. Docker’s own 101 tutorial teaches images, containers, volumes, Compose, networking, and image-building practices in that order. (docker.com) Kubernetes comes after that because it manages many containers at once: placing them on machines, restarting failed workloads, and exposing services to users. DevOpsCube’s current catalog includes beginner guides on the Kubernetes Gateway API, persistent volumes on Amazon Elastic Kubernetes Service, and in-place pod resizing with Vertical Pod Autoscaler. (devopscube.com) Certification remains part of the pitch because Linux Foundation exams such as Certified Kubernetes Administrator and Certified Kubernetes Application Developer still function as screening signals. DevOpsCube’s GitHub profile explicitly lists coupon resources and exam guides alongside project repositories. (github.com) What DevOpsCube is selling, in effect, is not a news roundup but a study sequence: learn containers, automate builds, deploy to Kubernetes, and document the result in public. Its own GitHub description makes that explicit by saying engineers should “learn by doing, not just reading.” (github.com)
