Overview

Install a chart archive, creating a release in the process.

helm install <chart-name>

helm install stable/mysql

Specifying a Release Name

helm install --name <release-name> ...

Overriding Default Configuration

Default configuration - or just some values - can be overridden in bulk with:

helm install -f|--values <configuration-overrides-file.yaml> <chart name>

The -f|--values flag can be specified multiple time on the command line, and the rightmost value will take precedence.

Individual configuration options can be specified with --set, --set-string and --set-file. If both --set and --values are used, the --set-specified configuration values are merged into the configuration values specified with --values, with higher precedence. Overrides specified with --set are persisted in a ConfigMap and can be viewed for a given release with helm get value <release-name>.

Overriding Tags and Conditions

Use --set to override default tag and condition values at installation time.

Installing from Different Sources

The default option for the helm install command is to install from the default repository. However, the chart may come from different sources:

Installing from a File

helm install something-0.1.1.tgz

Installing from an Unpacked Chart Directory

helm install ./something

Installing from a URL

helm install https://example.com/charts/something-1.0.0.tgz
