## Why people recommend it

Just bumping a yaml file in a git repo to the image tag I wanted deploying was a godsend and nearly automated." ([source](https://news.ycombinator.com/item?id=47926626)) "after the setup, anytime you push a new image and tag, k8s can automatically update without needing to do anything manual" ([source](https://news.ycombinator.com/item?id=47926595)) "There's something nice about using git to add a helm repo, a helm release with a few values, then 'git push'." ([source](https://news.ycombinator.com/item?id=47039407))
- Repeatable infrastructure from a small repo (3 comments): "an infra repo for operators using Flux, applying service level yaml from app repos in CI" ([source](https://news.ycombinator.com/item?id=48549043)) "my entire infrastructure is repeatable with just a small git repo of fluxcd stuff" ([source](https://news.ycombinator.com/item?id=47966977)) "Using GitOps (FluxCD) as deployment strategy enables no dependencies" ([source](https://news.ycombinator.com/item?id=47086808))
