Adds a subcommand to the installer binary `explain installconfig` that allows the users to see the fields available for install-config.yaml Users can use `explain installconfig[.subfield][.subfield]` to see documentation for subfields. The usage is very similar to `oc explain`

Description Scott Dodson 2020-05-01 12:14:49 UTC
install-config.yaml is a self documented api object but there's no accessible way to review the documentation for the API without going to github, it'd be nice if the installer provided a way to explain the API object and it were kept in sync with the specific version of the Installer I have downloaded as things change over time.

Comment 3 Mike Gahagan 2020-05-08 14:37:16 UTC
Confirmed openshift-install explain is working for installconfig, although we might want to clean up the example documentation a little since it references kubectl rather than openshift-install:

[m@localhost 45-azure-install]$ ./openshift-install explain -h
This command describes the fields associated with each supported InstallConfig API. Fields are identified via a simple
JSONPath identifier:


  openshift-install explain [flags]


# Get the documentation of the resource and its fields
kubectl explain installconfig

# Get the documentation of a AWS platform
kubectl explain installconfig.platform.aws

  -h, --help   help for explain

Global Flags:
      --dir string         assets directory (default ".")
      --log-level string   log level (e.g. "debug | info | warn | error") (default "info")

[m@localhost 45-azure-install]$ ./openshift-install explain installconfig
KIND:     InstallConfig

RESOURCE: <object>
  InstallConfig is the configuration for an OpenShift install.

    additionalTrustBundle <string>
      AdditionalTrustBundle is a PEM-encoded X.509 certificate bundle that will be added to the nodes' trusted certificate store.

    apiVersion <string>
      APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources

[m@localhost 45-azure-install]$ ./openshift-install explain installconfig.platform.azure
KIND:     InstallConfig

RESOURCE: <object>
  Azure is the configuration used when installing on Azure.

    baseDomainResourceGroupName <string>
      BaseDomainResourceGroupName specifies the resource group where the Azure DNS zone for the base domain is found.

    computeSubnet <string>
      ComputeSubnet specifies an existing subnet for use by compute nodes
