Nelm is meant to be a direct Helm 3 replacement, providing first-class Helm-chart support, yet improving on what Helm 3 offers.
Nelm is used as the deployment engine in werf, but Nelm will have its own CLI in the future for those who don't need everything that werf offers.
Nelm is based on Helm 3 — some parts of it improved and some, like the deployment subsystem, are rewritten from scratch to introduce:
terraform plan
-like capabilities
- Replacement of 3-Way Merge with Server-Side Apply
- Improved resource tracking built from the ground up
- Advanced resource ordering capabilities
- Flexible resource lifecycle management
- Fixes for numerous issues like this one and other improvements
