helm install

Install a chart archive

Synopsis

This command installs a chart archive.

The install argument must be a chart reference, a path to a packaged chart, a path to an unpacked chart directory or a URL.

To override values in a chart, use either the ‘–values’ flag and pass in a file or use the ‘–set’ flag and pass configuration from the command line. To force string values in ‘–set’, use ‘–set-string’ instead. In case a value is large and therefore you want not to use neither ‘–values’ nor ‘–set’, use ‘–set-file’ to read the single large value from file.

$ helm install -f myvalues.yaml ./redis

or

$ helm install --set name=prod ./redis

or

$ helm install --set-string long_int=1234567890 ./redis

or $ helm install –set-file multiline_text=path/to/textfile

You can specify the ‘–values’/‘-f’ flag multiple times. The priority will be given to the last (right-most) file specified. For example, if both myvalues.yaml and override.yaml contained a key called ‘Test’, the value set in override.yaml would take precedence:

$ helm install -f myvalues.yaml -f override.yaml ./redis

You can specify the ‘–set’ flag multiple times. The priority will be given to the last (right-most) set specified. For example, if both ‘bar’ and ‘newbar’ values are set for a key called ‘foo’, the ‘newbar’ value would take precedence:

$ helm install --set foo=bar --set foo=newbar ./redis

To check the generated manifests of a release without installing the chart, the ‘–debug’ and ‘–dry-run’ flags can be combined. This will still require a round-trip to the Tiller server.

If –verify is set, the chart MUST have a provenance file, and the provenance file MUST pass all verification steps.

There are five different ways you can express the chart you want to install:

1. By chart reference: helm install stable/mariadb
2. By path to a packaged chart: helm install ./nginx-1.2.3.tgz
3. By path to an unpacked chart directory: helm install ./nginx
4. By absolute URL: helm install https://example.com/charts/nginx-1.2.3.tgz
5. By chart reference and repo url: helm install –repo https://example.com/charts/ nginx

CHART REFERENCES

A chart reference is a convenient way of reference a chart in a chart repository.

When you use a chart reference with a repo prefix (‘stable/mariadb’), Helm will look in the local configuration for a chart repository named ‘stable’, and will then look for a chart in that repository whose name is ‘mariadb’. It will install the latest version of that chart unless you also supply a version number with the ‘–version’ flag.

To see the list of chart repositories, use ‘helm repo list’. To search for charts in a repository, use ‘helm search’.
