To install a particular version of Helm, you can use the following command:
1
|
helm install <release-name> <chart-name> --version <desired-version>

Replace <release-name> with the name you want to give to the release, <chart-name> with the name of the Helm chart you want to install, and <desired-version> with the specific version of the Helm chart you want to use.
By specifying the version flag, Helm will install the desired version of the chart. This can be useful if you need a specific version to ensure compatibility with your other resources or if you prefer the features of a particular release.

What is the difference between Helm v2 and v3?
Helm v2 and v3 are both versions of the Helm package manager for Kubernetes, but there are some key differences between them:
- Release management: In Helm v2, releases were managed using a server-side component called Tiller. In Helm v3, Tiller has been removed and releases are now managed directly by the client-side Helm application.
- Chart storage: In Helm v2, charts were stored in a centralized repository, which could lead to potential security vulnerabilities. In Helm v3, charts are stored locally on the client side, reducing the risk of security issues.
- Dependencies: Helm v2 had a separate command for managing dependencies, while Helm v3 integrated dependency management directly into the main Helm commands.
- API versioning: Helm v3 introduces changes to the API, including changes to the release storage format and the removal of certain APIs that were considered insecure.
Overall, Helm v3 simplifies the installation and management of Kubernetes applications by removing the need for a separate server-side component and improving security. It also streamlines the process of managing dependencies and introduces changes to the API to address security concerns.
