Introduction

Helm, the package manager for Kubernetes, provides the helm registry command to interact with OCI (Open Container Initiative) registries. This command enables users to manage Helm chart artifacts stored in OCI-compliant registries, facilitating chart distribution and sharing. In this article, we'll explore the helm registry command, its purpose, and how to use it effectively, accompanied by a practical example.

Understanding helm registry Command: The helm registry command allows users to interact with OCI-compliant registries to manage Helm chart artifacts. It provides functionalities to push, pull, and inspect Helm charts stored in OCI registries, enhancing chart distribution and sharing capabilities.

Interacting with Helm Chart Registries: Let's explore how to use the helm registry command to interact with Helm chart registries.

Example:

$ helm registry login myregistry.io
Username: <username>
Password: <password>
Login succeeded

Output:

Login succeeded

Interpreting the Output:

• The output confirms the successful login to the OCI registry hosted at myregistry.io.

Using helm registry Commands: Once authenticated, users can perform various operations using the helm registry command, such as pushing, pulling, or inspecting Helm chart artifacts in the registry.

Conclusion

The helm registry command is a powerful tool for interacting with OCI-compliant registries to manage Helm chart artifacts. By using this command, users can push, pull, and inspect Helm charts stored in OCI registries, facilitating chart distribution and sharing in Kubernetes environments.
