Today, I'm excited to announce the release of Kosko 4.1. This release is a significant milestone for Kosko.
The first major feature is the plugin system introduced in Kosko 4.0. It allows you to modify manifests, or run extra validations. Currently there are two official plugins, and we are going to introduce them in this post.
Kosko 3.0 has been released a few weeks ago. There are many improvements and some breaking changes in this version.
In the previous version, when you run kosko generate or kosko validate command, only the first error is reported. Error messages are cramped and there is a lot of useless information.
[kubernetes-models] 3.0 has been released last month. To upgrade to the latest kubernetes-models, run:
npm install kubernetes-models@latest
If you have installed any CRD packages, don't forget to upgrade them as well.
Kosko now supports Kustomize files. With the new @kosko/kustomize package, you can load your existing Kustomize files into Kosko, and it also supports Kubernetes OpenAPI schema validation.
@kosko/kustomize uses the kustomize build or kubectl kustomize command to generate Kubernetes manifests and the @kosko/yaml package to load Kubernetes YAML.
Last month, ECMAScript modules (ESM) support was shipped in Kosko 1.1. Today, you can use ESM not only in Node.js, but also in browsers. Currently only the following packages are browser-ready. Please make sure to update these packages before using Kosko in a browser.
@kosko/env - 2.0.0@kosko/generate - 1.2.0Most popular apps are available as Helm charts. It was not easy to use them in Kosko directly. The all new @kosko/helm package can help you load Helm charts, and of course, it also supports Kubernetes OpenAPI schema validation.
@kosko/helm uses the helm template command to render chart templates and the @kosko/yaml package to load Kubernetes YAML.
Kosko comes with ECMAScript modules (ESM) support since v1.1. You can write components and environments in native ESM files. The following packages are updated for ESM support. Please make sure to update these packages before using ESM.
@kosko/cli - 1.2.0@kosko/env - 1.1.0@kosko/generate - 1.1.0kosko - 1.1.0@kosko/migrate - 2.0.0@kosko/require - 2.0.0@kosko/yaml - 1.0.0It has been a long time since the last stable release v0.9. Recently, I decide to implement some features that I always want to have at work. Hope these new features can also help you.
In v1.0, arrays and functions in components are flattened. This is useful for sharing manifests across components.
