Overview of this book

DevOps Culture and Practice with OpenShift features many different real-world practices - some people-related, some process-related, some technology-related - to facilitate successful DevOps, and in turn OpenShift, adoption within your organization. It introduces many DevOps concepts and tools to connect culture and practice through a continuous loop of discovery, pivots, and delivery underpinned by a foundation of collaboration and software engineering. Containers and container-centric application lifecycle management are now an industry standard, and OpenShift has a leading position in a flourishing market of enterprise Kubernetes-based product offerings. DevOps Culture and Practice with OpenShift provides a roadmap for building empowered product teams within your organization. This guide brings together lean, agile, design thinking, DevOps, culture, facilitation, and hands-on technical enablement all in one book. Through a combination of real-world stories, a practical case study, facilitation guides, and technical implementation details, DevOps Culture and Practice with OpenShift provides tools and techniques to build a DevOps culture within your organization on Red Hat's OpenShift Container Platform.

This includes, among other things, managing secrets and adding webhooks to trigger our Jenkins automation as soon as a developer commits their code.

Connect Argo CD to Git

Let's talk about GitOps. We want our Git repositories to be the single source of truth and the Argo CD controller to analyze the differences between what is currently deployed to our cluster and what is stored in our Git repositories. Argo CD can do things based on the difference it sees between the desired state (in Git) and the actual state (in the cluster) such as automatically synchronizing them or sending a notification to say that these two states are not as expected. For example, in Git we may have set version 123 of our application...
