type Targets ¶

type Targets struct {
	// contains filtered or unexported fields
}

Targets implements the lister interface to provide RTC based target listing. Provides a means of listing targets stored in a Runtime Configuration value set. For information on how the RTC API works, see https://cloud.google.com/deployment-manager/runtime-configurator/reference/rest/

Each variable in RTC is a key/val pair. When listing targets, we assume the variables in the rtcservice.Config are laid out as <Hostname : RtcTargetInfo> where RtcTargetInfo is a base64 encoded RtcTargetInfo protobuf. The hostnames are listed, with one of their addresses assigned as a solve address. If groupTag is empty, no filtering by groupTag occurs. Otherwise, only variables with a group_tag matching an element of groupTag will be listed.

Note that this only provides a means to list targets stored in an RTC config. It does not provide means to maintain this list. When listing, however, Targets will ignore sufficiently old RTC entries, as configured by "exp_msec" in the TargetsConf protobuf.
