Functions

func GetValues

func GetValues(c EtcdClient, prefix string, keys []string) (map[string]interface{}, error)

GetValues queries etcd for keys prefixed by prefix. Etcd paths (keys) are translated into names more suitable for use in templates. For example if prefix where set to '/production' and one of the keys where '/nginx/port'; the prefixed '/production/nginx/port' key would be quired for. If the value for the prefixed key where 80, the returned map would contain the entry vars["nginx_port"] = "80".

func NewEtcdClient

func NewEtcdClient(machines []string, cert, key string) (*etcd.Client, error)

NewEtcdClient returns an *etcd.Client with a connection to named machines. It returns an error if a connection to the cluster cannot be made.

Types
