The templating engine handles errors originating from the `required` and `fail` template functions specially, cleaning up the error messages to be more presentable to users. Go's text/template package unfortunately does not make this straightforward to implement. Despite template.ExecError implementing Unwrap, the error value returned from the template function cannot be retrieved using errors.As. The wrapped error in ExecError is a pre-formatted error string with the template function's error string interpolated in with the original error value erased. Helm works around this limitation by delimiting the template-supplied message and extracting the message out of the ExecError string with a regex. Fix the parsing of `required` and `fail` error messages containing newlines by setting the regex flag to make `.` match newline characters. Signed-off-by: Cory Snider <csnider@mirantis.com>
Helm
Helm is a tool for managing Charts. Charts are packages of pre-configured Kubernetes resources.
Use Helm to:
- Find and use popular software packaged as Helm Charts to run in Kubernetes
- Share your own applications as Helm Charts
- Create reproducible builds of your Kubernetes applications
- Intelligently manage your Kubernetes manifest files
- Manage releases of Helm packages
Helm in a Handbasket
Helm is a tool that streamlines installing and managing Kubernetes applications. Think of it like apt/yum/homebrew for Kubernetes.
- Helm renders your templates and communicates with the Kubernetes API
- Helm runs on your laptop, CI/CD, or wherever you want it to run.
- Charts are Helm packages that contain at least two things:
- A description of the package (
Chart.yaml) - One or more templates, which contain Kubernetes manifest files
- A description of the package (
- Charts can be stored on disk, or fetched from remote chart repositories (like Debian or RedHat packages)
Install
Binary downloads of the Helm client can be found on the Releases page.
Unpack the helm binary and add it to your PATH and you are good to go!
If you want to use a package manager:
- Homebrew users can use
brew install helm. - Chocolatey users can use
choco install kubernetes-helm. - Scoop users can use
scoop install helm. - GoFish users can use
gofish install helm. - Snapcraft users can use
snap install helm --classic
To rapidly get Helm up and running, start with the Quick Start Guide.
See the installation guide for more options, including installing pre-releases.
