Before we go to battle, I’d want to provide some context to those of you who aren’t aware with GitOps and the technologies it employs. The foundation of GitOps is having code in a version-controlled location, such as a Git repository. This code is a declarative definition of the production-ready infrastructure, together with an automated technique to make sure it really exists.
This means that every issue may be fixed by using the git revert command, and that every pull request has the potential to bring a new feature to your audience. Therefore, just the code itself, not the production environment, has to be accessible to the developers. Remember that this in no way limits the creators’ freedom; rather, it expands the possibilities available to them by bringing the environment closer.
All About Flux CD and Argo CD
Well-known applications like Flux CD and Argo CD may help you keep your local environment in sync with the necessary states in your Git repository. In addition, you’ll have a better grasp of the bare bones functionality of each of these instruments, empowering you to choose the finest solution with confidence.
Argo Audio CD Usages
The Argo CD tool simplifies Kubernetes continuous delivery with its declarative features and GitOps integration. It contains features like scalability, security (including interaction with SSO), multi-cluster multi-tenancy support, and flexibility.
Installation for Audio CD
Argo CD’s installation is straightforward; just follow the directions on the getting started page.
To utilise the graphical user interface, expose the Argo CD server in one of two ways.
In addition to the graphical user interface, the argocd command line interface may be used to control the fundamental components of Argo CD. To get the CLI up and running, all you need to do is run the Flux CD.
All About Flux CD
Flux is a Kubernetes library that provides open, extendable, and continuous delivery solutions. Weaveworks pioneered the technology, and CNCF is now responsible for its development and maintenance.
Installation of Flux CD
Flux is designed with a focus on the command line interface (CLI) rather than a graphical user interface (UI). You may set up Flux CLI in one of two ways.
After installing the CLI, you can use the following command to install Flux on your Kubernetes cluster.

When compared to traditional GitOps, the Flux technique is more hands-off and straightforward. The technique begins with the Bootstrapping phase. This has resulted in the installation of the necessary flux components on the cluster for monitoring a directory on the Source. Reconciliation will include any newly available data from this source as it becomes available over the course of the procedure. It works with Kustomization, artefacts stored in buckets, and Helm releases.
Walkthrough of Flux CD
- The Git credentials used by flux CLI to connect to your repository must be exported.
- Checking the compatibility of your cluster is the next step. The final result should like this.
- Install flux on your cluster now using git configuration.
This will set up a test-repo in your GitHub account and include the Flux component manifest in the repository. The clustersdirectory in your cluster will be monitored in addition to the flux components being deployed and set up.
Now that you’ve finished setting everything up, you can begin using it. You may create whatever kind of manifest you want under the test-repo directory, and flux will keep polling it and deploying the modifications.
