Use the viocli update command to update the configuration of resources in your deployment. The configuration is loaded in the default text editor for you to modify.

The viocli update command uses the following syntax. 

viocli update resource-type [resource-name] [--live-debug={true | false}] [--force] [-v]
Parameter Mandatory or Optional Description

resource-type

Mandatory

Type of resource that you want to update. The following values are accepted:

  • aodh
  • barbican
  • ceilometer
  • ceilometeragent
  • cinder
  • deployment
  • designate
  • glance
  • gnocchi
  • heat
  • horizon
  • keystone
  • mariadb
  • memcached
  • neutron
  • nova
  • novacompute
  • panko
  • rabbitmq
  • swift
  • tenant-vdc

resource-name

Optional

Name of the resource that you want to update.

If only one instance of the desired resource is running, this parameter is not required.

--live-debug={true | false}

Optional

Used mostly by R&D during development to enable live debug mode on the specified resource.

To allow for debugging, starts the resource pod with "sleep infinity" rather than starting the core process.

Note: Live debug causes a control plane outage of the services being debugged.

To return to normal operations, use viocli to disable live debug and wait for the pods to restart.

Customers are advised to use this feature only under the direction of VMware technical services.

--force

Optional

Runs the command without confirmation.
-w or --watch

Optional

Watch service updates status in a synchronized way

-v or --verbose

Optional

Displays output in verbose mode.
