5 Install (or upgrade) an umbrella Helm Chart, and its subcharts, as separate Helm Releases
7 The umbrella Helm Chart is broken apart into a parent release and subchart releases.
8 Subcharts the are disabled (<chart>.enabled=false) will not be installed or upgraded.
9 All releases are grouped and deployed within the same namespace.
12 The deploy arguments must be a release and chart. The chart
13 argument can be either: a chart reference('stable/onap'), a path to a chart directory,
14 a packaged chart, or a fully qualified URL. For chart references, the latest
15 version will be specified unless the '--version' flag is set.
17 To override values in a chart, use either the '--values' flag and pass in a file
18 or use the '--set' flag and pass configuration from the command line, to force string
19 values, use '--set-string'.
21 You can specify the '--values'/'-f' flag multiple times. The priority will be given to the
22 last (right-most) file specified. For example, if both myvalues.yaml and override.yaml
23 contained a key called 'Test', the value set in override.yaml would take precedence:
25 $ helm deploy demo ./onap --namespace onap -f openstack.yaml -f overrides.yaml
27 You can specify the '--set' flag multiple times. The priority will be given to the
28 last (right-most) set specified. For example, if both 'bar' and 'newbar' values are
29 set for a key called 'foo', the 'newbar' value would take precedence:
31 $ helm deploy demo local/onap --namespace onap -f overrides.yaml --set log.enabled=false --set vid.enabled=false
34 helm deploy [RELEASE] [CHART] [flags]
37 --namespace string namespace to install the release into. Defaults to the current kube config namespace.
38 --set stringArray set values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
39 --set-string stringArray set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
40 -f, --values valueFiles specify values in a YAML file or a URL(can specify multiple) (default [])
41 --verbose enables full helm install/upgrade output during deploy
42 --set-last-applied set the last-applied-configuration annotation on all objects.This annotation is required to restore services using Ark/Veloro backup restore.
