Golang NewFilter Examples

Example #1

File: provider.go Project: makyo/juju

// machinesFilter returns a nova.Filter matching all machines in the environment.
func (e *Environ) machinesFilter() *nova.Filter {
	filter := nova.NewFilter()
	eUUID := e.Config().UUID()
	filter.Set(nova.FilterServer, fmt.Sprintf("juju-%s-machine-\\d*", eUUID))
	return filter
}

Example #2

File: upgrade.go Project: exekias/juju

// oldMachinesFilter returns a nova.Filter matching all machines in the environment
// that use the old name schema (juju-EnvironmentName-number).
func oldMachinesFilter(e *Environ) *nova.Filter {
	filter := nova.NewFilter()
	filter.Set(nova.FilterServer, fmt.Sprintf("juju-%s-machine-\\d*", e.Config().Name()))
	return filter
}

Example #3

File: provider.go Project: bac/juju

// jujuMachineFilter returns a nova.Filter matching machines created by Juju.
// The machines are not filtered to any particular environment. To do that,
// instance tags must be compared.
func jujuMachineFilter() *nova.Filter {
	filter := nova.NewFilter()
	filter.Set(nova.FilterServer, "juju-.*")
	return filter
}
