Imagine ?????? as a digital filing cabinet for your project, where you can store different versions of your files. Each time you make a change, you save it in a labeled folder (????????????). ???????????? is like sharing that filing cabinet with your team online, allowing everyone to access, contribute, and manage the files together. So, if someone makes a mistake, you can easily go back to a previous version, just like retrieving an old file from a folder in the cabinet.

Git is utility central and knowledge of Git as code versioning (providing code lifecycles) is central. Before exploring additional tools, GitLab or otherwise, it is important to have a good understanding of Git. Namely, a deep understanding of git merge and git branch and collaboration between devops. If you miss this, then many things will look like magic things)

Imagine Kubernetes as a ?????????????? ???????? where you manage buildings (????????????????????) and roads (????????????????????) efficiently. Helm, on the other hand, is like a construction manager who helps you quickly assemble and deploy buildings (????????????????????????) using pre-designed blueprints (????????????).

Mastering GitOps at scale pretty much means becoming an Helm chart samurai: being Helm the de facto application packaging and delivery medium for Kubernetes, it's just natural to use it as the atom of deployment for GitOps. Most GitOps controllers are really Helm chart reconcilers, so you better get a good hang on how to write, test and deploy Helm charts (two very useful tools are helm-docs for automated doc generation and the helm-releaser github action, to create, store and serve charts out of Github pages).

Kubernetes manages containerized apps, vital for GitOps. Learn its basics like pods and services. Helm simplifies app deployment in Kubernetes using charts. Explore online tutorials and docs to grasp Kubernetes and Helm.

Kubernetes is essential for orchestrating containerized applications, enabling scalable and resilient deployments. Helm, the package manager for Kubernetes, streamlines the deployment of applications and their dependencies into Kubernetes clusters. Essential skills include understanding Kubernetes objects (like pods, services, and deployments), managing cluster resources, and deploying applications with Helm charts for repeatable and consistent deployments. To learn these, start with Kubernetes' official documentation and tutorials. Practice deploying applications using Helm on a local cluster with tools like Minikube or Kind. Explore community charts and contribute to open-source Helm projects to gain hands-on experience.

In Kubernetes, deployments are handled autonomously. Updates are applied once, and Kubernetes manages the rollout across all instances. Kubernetes, as an orchestration tool, translates code infrastructure into functional systems. Management can be done at various levels: using your own cluster, a Managed Kubernetes cluster, or through Kubernetes manifests for low-level management. Helm provides a higher-level approach, allowing you to programmatically generate final manifests based on conditions and parameters. It splits a single deployment file into manageable components and includes a library for launching applications.

Imagine Terraform as a ?????????????????? for building your cloud infrastructure, like architects drafting plans for a skyscraper. Pulumi, on the other hand, is like a ?????????????????? ?????????????? that lets you build the same skyscraper using various tools, like LEGO bricks, depending on your preference.

Terraform and Pulumi are tools for Infrastructure as Code (IaC). Terraform uses declarative configuration files to manage infrastructure, while Pulumi offers a code-first approach using familiar programming languages. Both tools automate provisioning, ensuring consistent and scalable infrastructure.

Terraform and Pulumi help manage cloud infrastructure using code. Learn how to define infrastructure using Terraform's HCL or Pulumi's languages.

To learn these tools, start with the official documentation and tutorials for both Terraform and Pulumi. Practice by creating and managing simple cloud infrastructure projects. Engage with the community through forums and contribute to open-source projects for real-world experience.

Argo CD and Flux are GitOps tools for Kubernetes that automate the continuous deployment of applications. Argo CD offers a UI for visualizing and managing Kubernetes deployments, while Flux focuses on simplicity, syncing cluster state directly from Git. Both ensure declarative, version-controlled deployments.

Imagine you have a Kubernetes cluster where you deploy your web application. With ???????? ???? ???? ????????, you link your cluster to a Git repository containing your application's manifests. When you push changes to the repository, these tools automatically update your cluster to match the new state, ensuring your application is always up-to-date without manual intervention. For instance, if you modify the number of replicas in your deployment YAML file and push the changes, ???????? ???? ???? ???????? will automatically adjust the number of pods in your cluster accordingly.

Argo CD and Flux are similar software products with the same goals but function differently. They are positioned between the Git repository and Helm, and then Kubernetes. Argo CD can be installed on Kubernetes.

Argo CD and Flux automate Kubernetes app delivery via GitOps. Sync cluster state with git repo declaratively for reliability. Configure pipelines, define apps and customize sync policies. Explore features like Argo Rollouts and Flux Notifications in tutorials and docs.

One thing I have found helpful is Flux's integration capabilities, including Flux Notifications and Image Automation. These features enable automatic updates based on changes in container image versions and provide alerting mechanisms for deployments. Such extensions enhance the robustness and automation of GitOps practices, ensuring deployments are efficient and reliable.

Imagine you're monitoring your Kubernetes cluster with ???????????????????? and visualizing the data with ??????????????. ???????????????????? collects metrics like CPU and memory usage, while ?????????????? displays them in customizable dashboards. For example, you can create a ?????????????? dashboard showing the CPU utilization of your Kubernetes pods over time, helping you identify performance trends and potential issues.

Prometheus and Grafana monitor and visualize gitops apps. Prometheus gathers metrics from various sources. Grafana displays metrics through dashboards, charts, and alerts. Set up monitoring, define targets, and rules, and import dashboards. Learn from online resources, docs, and books.

Prometheus - exports metrics (example - HTTP request total). Prometheus - collects and stores metrics and provides an efficient query language. It is statistical and native to all that run on Kubernetes. Prometheus - Alertmanager component. Grafana - visualizes metrics. You can create any dashboards.

Tools like Prometheus, Grafana, and Loki help monitor and observe your GitOps processes, ensuring everything is working as expected.Learn how to set up monitoring tools to track the health of your infrastructure and applications.
