Types

type Client

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

Client is a wrapper around the etcd client

func NewEtcdClient

func NewEtcdClient(machines []string, cert, key string, caCert string) (*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.

func (*Client) GetValues

func (c *Client) GetValues(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 were set to '/production' and one of the keys were '/nginx/port'; the prefixed '/production/nginx/port' key would be queried for. If the value for the prefixed key where 80, the returned map would contain the entry vars["nginx_port"] = "80".

type EtcdClient

type EtcdClient interface {
	Get(key string, sort, recurse bool) (*etcd.Response, error)
}
