helmt - A simple wrapper around helm template
Sometimes you only want to use helm to template Kubernetes manifests.
Usage:
helmt <filename> [flags]
Flags:
--config string config file (default is $HOME/.helmt.yaml)
-h, --help help for helmt
-p, --password string optional password for chart repository
-u, --username string optional username for chart repository
-v, --version version for helmt
Flags, environment variables and config file
The following flags can also be set via environment variables. But command line parameters have always precedence.
| Flag | Environment variable |
|---|---|
| config | HELMT_CONFIG |
| username | HELMT_USERNAME |
| password | HELMT_PASSWORD |
The config is a simple yaml file with the names of the flags as keys. Example:
username: anonymous
Please note that environment variables and command line parameters overwrite these settings.
Example
All you need to do is to create a yaml file describing which chart you want to template:
chart: jenkins
version: 2.0.0
repository: https://kubernetes-charts.storage.googleapis.com
name: jenkins
or
chart: syncier-jenkins
version: 5.6.0
repository: https://hub.syncier.cloud/chartrepo/library/charts
namespace: jenkins
name: jenkins
values:
- values1.yaml
- values2.yaml
Then you can run helmt helm-charts.yaml and it will download the chart and render the contents using the parameters defined in the yaml file.
