Everything in this series so far has implicitly assumed a relatively simple setup: one team, one or a handful of clusters, one ArgoCD instance, a config repo with a reasonable number of applications. That setup works…
Rolling updates, which we covered back in the Kubernetes series, are a significant improvement over taking your service down to deploy a new version. But they have a blind spot: the moment the rollout completes, 100%…
Everything we’ve covered so far has a satisfying elegance to it. Desired state in Git. ArgoCD watching. Cluster reconciling. The whole system is auditable, reproducible, and self-healing. Then someone asks: “where do…
By now you have a Git repo, ArgoCD watching it, and a folder structure that separates environments. The next problem is one that every team hits within the first week: your payments API in dev and your payments API…
Here’s a conversation that happens on almost every team adopting GitOps for the first time. You’ve got ArgoCD running, you’ve written your first Application, you’ve seen the sync work. Now someone asks: “where…
The last two posts covered the theory. GitOps is a good idea. The four principles make sense. Now let’s talk about the software that actually implements it. ArgoCD is the most widely used GitOps controller for…
GitOps gets thrown around a lot as a buzzword, which means it gets applied to a lot of things that aren’t quite it. “We store our manifests in Git” — not quite. “Our CI pipeline runs kubectl apply” — closer, but…
If you’ve been running Kubernetes for a while, you’ve probably settled into a deployment workflow that looks something like this. A developer finishes a feature. CI builds and pushes a new image. Someone — maybe a…
