Helm is een populaire package manager waarmee voorgeconfigureerde Kubernetes resources, oftewel Charts, kunnen worden opgezet, beheerd en gedeeld. Helm kan via Brew, Chocolatey, Scoop of Snap worden geïnstalleerd, en binaries kunnen op GitHub worden gevonden. Enkele dagen is is versie 4.0.0 uitgekomen en de belangrijkste veranderingen die daarin zijn aangebracht zijn hieronder voor je op een rijtje gezet.
New FeaturesHelm 4 has numerous new features, but a few deserve highlighting here:
- Redesigned plugin system that supports Web Assembly based plugins
- Post-renderers are now plugins
- Server side apply is now supported
- Improved resource watching, to support waiting, based on kstatus
- Local Content-based caching (e.g. for charts)
- Logging via slog enabling SDK logging to integrate with modern loggers
- Reproducible builds of chart archives
- Updated SDK API including support for multiple chart API versions (new experimental v3 chart API version coming soon)
For full release notes, please see: https://helm.sh/docs/overview/
Compatibility with Helm v3Helm v4 is a major version with backward incompatible changes including to the flags and output of the Helm CLI and to the SDK. Please evaluate the changes to your workflows. The changes are not as extensive as those from Helm v2 to v3, with the goal that the majority of workflows remain compatible between Helm v3 and v4.
Helm charts apiVersion v2 (majority of today's charts) will continue to be supported in Helm v4. Existing charts should continue to install, upgrade, and otherwise work. Please test the installation and upgrade of charts to ensure it works as expected. Changes (e.g., server side apply) may impact the experience.
