| Install (or upgrade) an umbrella Helm Chart, and its subcharts, as separate Helm Releases |
| |
| The umbrella Helm Chart is broken apart into a parent release and subchart releases. |
| Subcharts the are disabled (<chart>.enabled=false) will not be installed or upgraded. |
| All releases are grouped and deployed within the same namespace. |
| |
| |
| The deploy arguments must be a release and chart. The chart |
| argument can be either: a chart reference('stable/onap'), 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'. |
| |
| 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 deploy demo ./onap --namespace onap -f openstack.yaml -f overrides.yaml |
| |
| 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 deploy demo local/onap --namespace onap -f overrides.yaml --set log.enabled=false --set vid.enabled=false |
| |
| Usage: |
| helm deploy [RELEASE] [CHART] [flags] |
| |
| Flags: |
| --namespace string namespace to install the release into. Defaults to the current kube config namespace. |
| --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) |
| -f, --values valueFiles specify values in a YAML file or a URL(can specify multiple) (default []) |
| --verbose enables full helm install/upgrade output during deploy |
| --set-last-applied set the last-applied-configuration annotation on all objects.This annotation is required to restore services using Ark/Veloro backup restore. |
