helm rollback [flags] [RELEASE] [REVISION]

helm upgrade

It upgrades a release to a specified version of a chart and/or updates chart values. To customize the chart values, use any of - ‘–values’/‘-f’ to pass in a yaml file holding settings, - ‘–set’ to provide one or more key=val pairs directly.

helm upgrade -f myvalues.yaml -f override.yaml redis ./redis
$ helm upgrade --set pwd='3jk$o2z=f\\30.e' redis ./redis


If no chart value arguments are provided on the command line, any existing customized values are carried forward. If you want to revert to just the values provided in the chart, use the ‘–reset-values flag.

  • list of resources that this release consists of, sorted by kind
  • details on last test suite run, if applicable - additional notes provided by the chart
