Helm
What it is
Helm is a free package manager for applications running in Kubernetes clusters. It groups related Kubernetes resources into versioned charts that can be shared, installed, upgraded, or rolled back. Charts can declare dependencies on other charts, and teams can supply different values to the same chart for development, staging, and production. Helm can install and manage applications including databases, monitoring stacks, and ingress controllers. Its command-line client communicates with the Kubernetes API server, while its library handles chart operations. Release information is stored in Kubernetes Secrets, so Helm does not need its own database. Charts can be kept on disk or retrieved from remote repositories, with Artifact Hub listing publicly available charts. Plugins extend the core feature set and can add custom chart download protocols. Helm runs on Linux, macOS, and Windows as a self-managed command-line tool under the Apache-2.0 license. Its scope is applications within a cluster: setting up and operating the Kubernetes cluster itself is outside its scope. Helm identifies application operators, distributors, developers, and supporting tool developers among its user roles. Community support is available through Kubernetes Slack channels, a mailing list, developer calls, Stack Overflow, and GitHub.
For and against
For
- Charts support installation, upgrades, and rollbacks.
- One chart can use values for different environments.
- Dependencies can be installed together.
- Release information is stored in Kubernetes Secrets.
- Free, self-managed command-line tool for three operating systems.
Against
- Cluster setup and operation are outside Helm's scope.
- Helm is a command-line tool.
- Community support is offered through listed channels.
The verdict
Helm provides a chart-based way to package and manage applications inside Kubernetes clusters, with environment-specific values and release rollbacks. Choose it for application management rather than cluster provisioning or operations.
Who it suits
Helm suits Kubernetes application operators, distributors, developers, and tool developers who need to package and manage applications in a cluster. It is not for managing the cluster infrastructure itself.
