Helm Upgrade

helm upgrade

upgrade a release

Synopsis

This command upgrades a release to a new version of a chart.

The upgrade arguments must be a release and chart. The chart argument can be either: a chart reference('example/mariadb'), a path to a chart directory, a packaged chart, or a fully qualified URL. For chart references, the latest version will be specified unless the '--version' flag is set.

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, use '--set-string'. 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.

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 upgrade -f myvalues.yaml -f override.yaml redis ./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 upgrade --set foo=bar --set foo=newbar redis ./redis
helm upgrade [RELEASE] [CHART] [flags]
