Automatically Continuously Reconciled GitOps and CI/CD Traditional CI/CD Workflows Where does GitOps fit in? Operations via Pull Request Summary 14 Chapter 2–Tools of the Trade Chapter 5–Repository and Directory Structures Best Practices DRY Parameterize Where You Need To Repository Considerations Monorepo Polyrepo Directory Structures tools that had fully embraced Kubernetes natively. But a line in that podcast set the course for where I wanted things to head: “To me, GitOps is the holy grail of software and infrastructure management

in the Git repo) but of course, requires manual intervention. 3. You can have a combination where the GitOps tool itself both syncs a previous Git hash to the cluster and auto-commits (or reverts) repository for all environments (or clusters) where all people collaborate along with the CI/CD systems. This creates the problem of Git conflicts (where your Git repos are touched by many CI processes values for each environment (e.g. QA/staging/production). Helm on its own does not dictate where those 3 components (source code, manifests, values) should reside. You can keep all of them in the

on delivering business value via code. Thus, to improve developer experience, GitOps emerged where infrastructure and application configuration changes revolve around Git, i.e., the version control system should take care of it ahead of time. The opposite of declarative is an imperative approach where you try to define the sequence of steps, which unfortunately is an additional overhead on the operator look at a few popular ones below: HELM Helm is based on the parameterized templating approach where all resource definition files of applications are templated to make them customizable based on

you have a single place from which everything is derived and driven. This trivializes rollbacks; where you can use a `Git revert` to go back to your previous application state. With Git’s excellent security Part 1: Spin up a Kubernetes Cluster eBook 19 7. Join the Nodes to the Master The nodes are where the workloads (containers and pods, etc) run. Join the nodes to your cluster with (shown on the master front-end repo in Travis: DOCKER_USER=<”user-name+robot-account”> DOCKER_PASS=<”robot-token”> Where, <”user-name+ci_push_pull”> is your user-name including the + sign and the name of the robot account

replicable, automated, immutable construct where your change management, everything happens in Git…. Everything is founded on that infrastructure as GitOps mindset where your design stays in Git, and everything deployment. Now, instead of outages, they have automatic rollbacks. In fact, they had an incident where a corrupt configuration that made it to production did not even raise an alert because the release phased approach The time it takes for your organization to adopt a GitOps approach greatly depends on where you are in your DevOps journey. If you’ve already been leveraging Git for collaboration, have a
