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]

--cleanup-on-fail allow deletion of new resources created in this upgrade when upgrade fails
--create-namespace if --install is set, create the release namespace if not present
--description string add a custom description
--devel use development versions, too. Equivalent to version '>0.0.0-0'. If --version is set, this is ignored
--disable-openapi-validation if set, the upgrade process will not validate rendered templates against the Kubernetes OpenAPI Schema
--dry-run simulate an upgrade
--force force resource updates through a replacement strategy
-h, --help help for upgrade
--history-max int limit the maximum number of revisions saved per release. Use 0 for no limit (default 10)
-i, --install if a release by this name doesn't already exist, run an install

--render-subchart-notes if set, render subchart notes along with the parent
--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

--set stringArray set values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
--set-file stringArray set values from respective files specified via the command line (can specify multiple or separate values with commas: key1=path1,key2=path2)
--set-string stringArray set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
--skip-crds if set, no CRDs will be installed when an upgrade is performed with install flag enabled. By default, CRDs are installed if not already present, when an upgrade is performed with install flag enabled
--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
