Kustomize logo Kustomize

Kustomize is an intelligent Kubernetes native configuration management software that comes with the manifestation to add, remove, or update configuration options without the need for forking.

Git logo Git

Git is a free and open source version control system designed to handle everything from small to very large projects with speed and efficiency. It is easy to learn and lightweight with lighting fast performance that outclasses competitors.

Kustomize features and specs

  • Declarative Syntax
    Kustomize provides a declarative approach to managing Kubernetes configurations, allowing users to specify desired states in YAML files rather than using scripts or imperative commands.
  • No Templating Required
    Unlike Helm, Kustomize does not use templates, reducing complexity and potential errors in rendering templates. Users can simply modify YAML files directly.
  • Layered Customization
    It allows users to apply multiple overlays or transformations to base configurations, enabling a modular and reusable approach to manage environments like dev, staging, and production.
  • Integration with kubectl
    Kustomize is integrated with kubectl since version 1.14, making it easy to use and deploy directly from the command line without needing additional tools.

Possible disadvantages of Kustomize

  • Complexity for Large Projects
    While Kustomize is great for simple transformations, managing large projects with many overlays can become complex, as dependencies and transformations have to be explicitly defined and managed.
  • Limited Features Compared to Helm
    Kustomize offers fewer features compared to Helm, such as lifecycle management and rich templating, which might be needed for more sophisticated deployment requirements.
  • Learning Curve
    Users new to Kubernetes configuration management might find Kustomize's model and functions hard to grasp initially, as it requires understanding of its specific YAML structure and practices.
  • Lack of Native Dependency Management
    Kustomize does not support native dependency management of resources, which can complicate handling interdependent resources compared to other tools like Helm.

Git features and specs

  • Distributed Version Control
    Git is a distributed version control system, meaning every user has a complete local copy of the repository. This offers better redundancy and allows users to work offline.
  • Branching and Merging
    Git makes branching and merging processes simple and efficient, allowing users to try out new features, fix bugs, or experiment without affecting the main codebase.
  • Speed
    Git operates very quickly because most of its operations are performed locally, making it very swift in comparison to some other version control systems.
  • Flexibility
    It is highly flexible, supporting various workflows including centralized, feature-branch, Gitflow, and forking workflows.
  • Open Source
    Being an open-source tool, it's free to use, and its source code can be reviewed and modified by anyone as needed.
  • Widely Supported
    Git is widely supported by many integrated development environments (IDEs) and collaborative platforms like GitHub, GitLab, and Bitbucket.
  • Security
    Git uses a mechanism of checksums to ensure data integrity, making it very resilient against changes, corruption, and unauthorized alterations.

Possible disadvantages of Git

  • Complexity for Beginners
    New users may find Git's command-line interface and concepts like branching, merging, and rebasing to be complex and difficult to learn.
  • Overhead of Local Repositories
    Since every user maintains a full copy of the repository, this could lead to higher local storage requirements compared to some other version control systems.
  • Learning Curve
    The initial setup and understanding of Git workflows can be challenging, and it requires users to spend some time learning the tool.
  • Potential for Misuse
    Powerful features like force push and interactive rebase can lead to significant issues if misused, including loss of history and data.
  • Merge Conflicts
    While merging is generally easy, complicated projects with many contributors might experience frequent and difficult-to-resolve merge conflicts.
  • Tool Fragmentation
    There are multiple tools and additional software built around Git (GUI clients, integrations, etc.), which can be overwhelming and fragmented for some users.

Analysis of Git

  • Release on Demand
    When a change earns its way onto main, the train builds the container image one time and tags it by the commit SHA. That image is the artifact. It runs in dev immediately. And here's the part that makes promotion boring: shipping to prod doesn't rebuild anything. It re-points a config overlay (a Kustomize overlay, in practice, committed to the same repo) at the same SHA that's already running in dev. Same bytes,... - Source: dev.to / 3 months ago

    Once I covered these basic use cases, I started to review the code base of the InnerSource pipeline project. At this point I learned about kustomize which is a Kubernetes native way for updating existing configurations. This tool was used in the project to customize default configurations of various manifests, so that new, slightly different ones could be created without code duplication.

  • GitHub, Demystified
    One last source of confusion worth clearing up. Git is the version control system itself, the underlying technology that does the change-tracking. GitHub is one popular place to host projects that use Git, and it is not the only one. GitLab and Bitbucket do much the same job. A beginner does not need to evaluate all three. Picking the one a tutorial or a friend already uses is a fine way to start because... - Source: dev.to / 3 months ago
