GitOps

GitOps is a modern operational model for cloud-native applications and infrastructure​

Here's what it's all about

  • Declare What You Want: Instead of diving into the nitty-gritty details of system setup, you just declare how you want things to be, and you store that info in your trusty version control. Changes happen through pull requests, making everything transparent, reviewable, and versioned.
  • Keep It Flowing: GitOps is all about automation. Your system gets updates automatically whenever there's a change in your Git repository. This means your system is always on point, just the way you like it.
  • Keep an Eye on Things: GitOps doesn't just set it and forget it. It gives you eyes on your system by keeping track of all those config changes. Monitoring tools are there to spot any hiccups and get things back on track pronto.

FluxCD: Making GitOps Happen​

FluxCD is the magic behind GitOps for Kubernetes clusters. It's like the conductor of your continuous delivery orchestra, making sure your cluster dances to the beat of your Git repos.

Here's what FluxCD is all about, in plain talk:

  • Automate Everything: FluxCD handles the heavy lifting of deploying and managing Kubernetes stuff based on what's in your Git repos. Say goodbye to manual headaches and hello to consistent setups across the board.
  • Git is King: FluxCD treats your Git repos like royalty, using them as the holy grail of truth for what your Kubernetes cluster should look like. Changes? They happen through Git, where everyone can see what's going on.
  • Sturdy Setup: FluxCD is all about building on solid ground. It pushes for immutable setups, meaning once something's declared, it stays that way. This keeps your deployments rock-solid and secure.
  • Plays Well with Others: FluxCD isn't a lone wolf. It buddies up with other GitOps tools and Kubernetes pals like Helm, Kustomize, and Prometheus. Together, they create a sweet setup tailored for modern cloud-native apps.

So, that's GitOps and FluxCD in a nutshell—making infrastructure a breeze with code, automation, and a sprinkle of continuous delivery magic.
