Functions

func GetCluster

func GetCluster(durl, dproxyurl string) (string, error)

GetCluster will connect to the discovery service at the given url and retrieve a string describing the cluster

func JoinCluster

func JoinCluster(durl, dproxyurl string, id types.ID, config string) (string, error)

JoinCluster will connect to the discovery service at the given url, and register the server represented by the given id and config to the cluster

func SRVGetCluster

func SRVGetCluster(name, dns string, apurls types.URLs) (string, error)

SRVGetCluster gets the cluster information via DNS discovery. TODO(barakmich): Currently ignores priority and weight (as they don't make as much sense for a bootstrap) Also sees each entry as a separate instance.
