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]

--repo string chart repository url where to locate the requested chart
--reset-values when upgrading, reset the values to the ones built into the chart
--reuse-values when upgrading, reuse the last release's values and merge in any overrides from the command line via --set and -f. If '--reset-values' is specified, this is ignored
--set stringArray set values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)

--set-string stringArray set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
--timeout duration time to wait for any individual Kubernetes operation (like Jobs for hooks) (default 5m0s)
--username string chart repository username where to locate the requested chart
-f, --values strings specify values in a YAML file or a URL(can specify multiple)
--verify verify the package before installing it
--version string specify the exact chart version to install. If this is not specified, the latest version is installed
--wait if set, will wait until all Pods, PVCs, Services, and minimum number of Pods of a Deployment, StatefulSet, or ReplicaSet are in a ready state before marking the release as successful. It will wait for as long as --timeout
