argo-helm-updater 📦 ⬆️

Helps you to identify outdated helm charts in your argocd instance.



This tool helps you to identify and update your helm charts, that are deployed with argocd. It retrieves all 'Application' CRDs from the given context and namespace. Since these applications contain all information about the helm deployment, if one is used, this tool queries the given repository for the latest chart version and displays a difference, if a newer version is deployed.

📦 Requirements

• rust

or

• nix
• direnv

🚀 Getting started

Clone the repository and make sure the dependencies are installed. You either need rust or nix installed. With nix use either nix-shell or direnv allow up to your preferences. After dependencies are available run cargo install --path . to build and install the tool.

Then you should be able to call the tool with argo-helm-updater. It will search for the Application CRD of argo in the current configured context and namespace. Use the --context and --namespace flags to search in other clusters and namespaces.

If you'd like to update the helm version in the cluster, run argo-helm-updater with the --update flage. It will prompt on each new version with a confirmation whether you'd like to update the Application or not.

❄️ Installation with nix

Add the following code to your overlays. Then argo-helm-updater can be installed from pkgs.

final: prev: {
  argo-helm-updater = prev.pkgs.rustPlatform.buildRustPackage rec {
    version = "0.2.1";
    pname = "argo-helm-updater";

    src = prev.fetchFromGitHub {
      owner = "dj95";
      repo = pname;
      rev = "f2d8222d448016086adf2313a7c12eb5975321fd";
      sha256 = "sha256-DPzmCaw7CGGbVdrbV9JgnU5XSSNj8PW+7Wjx9KSprfI=";
    };

    cargoSha256 = "sha256-Ooi2SpTuUA2TbW9uQCgzflCfiS0WKgkDdBZ2Sg7PvkA=";

    nativeBuildInputs = [
      prev.pkgs.pkg-config
      prev.pkgs.libiconv
      prev.pkgs.openssl
    ];

    buildInputs = [] ++ prev.pkgs.lib.optionals prev.pkgs.stdenv.isDarwin [
      prev.pkgs.darwin.apple_sdk.frameworks.Cocoa
      prev.pkgs.darwin.apple_sdk.frameworks.CoreGraphics
      prev.pkgs.darwin.apple_sdk.frameworks.Foundation
      prev.pkgs.darwin.apple_sdk.frameworks.IOKit
      prev.pkgs.darwin.apple_sdk.frameworks.Kernel
      prev.pkgs.darwin.apple_sdk.frameworks.OpenGL
      prev.pkgs.darwin.apple_sdk.frameworks.Security
    ];

    PKG_CONFIG_PATH = "${prev.pkgs.openssl.dev}/lib/pkgconfig";
  };
}

If you just want to try it with nix, run the following command.

nix run 'github:dj95/argo-helm-updater'
