Types ¶
type File ¶
File checks the provided Path, at the provided Interval for new Go binaries. When a new binary is found it will replace the currently running binary.
type Github ¶
type Github struct {
//Github username and repository name
User, Repo string
//Interval between fetches
Interval time.Duration
//Asset is used to find matching release asset.
//By default a file will match if it contains
//both GOOS and GOARCH.
Asset func(filename string) bool
// contains filtered or unexported fields
}
Github uses the Github V3 API to retrieve the latest release of a given repository and enumerate its assets. If a release contains a matching asset, it will fetch and return its io.Reader stream.
type HTTP ¶
type HTTP struct { //URL to poll for new binaries URL string Interval time.Duration CheckHeaders []string // contains filtered or unexported fields }
type Interface ¶
type Interface interface { //Init should perform validation on fields. For //example, ensure the appropriate URLs or keys //are defined or ensure there is connectivity //to the appropriate web service. Init() error //Fetch should check if there is an updated //binary to fetch, and then stream it back the //form of an io.Reader. If io.Reader is nil, //then it is assumed there are no updates. Fetch //will be run repeatedly and forever. It is up the //implementation to throttle the fetch frequency. Fetch() (io.Reader, error) }
Interface defines the required fetcher functions
type S3 ¶
type S3 struct { //Access key falls back to env AWS_ACCESS_KEY, then metadata Access string //Secret key falls back to env AWS_SECRET_ACCESS_KEY, then metadata Secret string //Region defaults to ap-southeast-2 Region string Bucket string Key string //Interval between checks Interval time.Duration //HeadTimeout defaults to 5 seconds HeadTimeout time.Duration //GetTimeout defaults to 5 minutes GetTimeout time.Duration // contains filtered or unexported fields }
S3 uses authenticated HEAD requests to poll the status of a given object. If it detects this file has been updated, it will perform an object GET and return its io.Reader stream.
