示例1: ServeApi
// ServeApi loops through all of the protocols sent in to docker and spawns
// off a go routine to setup a serving http.Server for each.
func ServeApi(job *engine.Job) engine.Status {
if len(job.Args) == 0 {
return job.Errorf("usage: %s PROTO://ADDR [PROTO://ADDR ...]", job.Name)
}
var (
protoAddrs = job.Args
chErrors = make(chan error, len(protoAddrs))
)
activationLock = make(chan struct{})
for _, protoAddr := range protoAddrs {
protoAddrParts := strings.SplitN(protoAddr, "://", 2)
if len(protoAddrParts) != 2 {
return job.Errorf("usage: %s PROTO://ADDR [PROTO://ADDR ...]", job.Name)
}
go func() {
log.Infof("Listening for HTTP on %s (%s)", protoAddrParts[0], protoAddrParts[1])
srv, err := NewServer(protoAddrParts[0], protoAddrParts[1], job)
if err != nil {
chErrors <- err
return
}
chErrors <- srv.Serve()
}()
}
for i := 0; i < len(protoAddrs); i++ {
err := <-chErrors
if err != nil {
return job.Error(err)
}
}
return engine.StatusOK
}示例2: Search
// Search queries the public registry for images matching the specified
// search terms, and returns the results.
//
// Argument syntax: search TERM
//
// Option environment:
// 'authConfig': json-encoded credentials to authenticate against the registry.
// The search extends to images only accessible via the credentials.
//
// 'metaHeaders': extra HTTP headers to include in the request to the registry.
// The headers should be passed as a json-encoded dictionary.
//
// Output:
// Results are sent as a collection of structured messages (using engine.Table).
// Each result is sent as a separate message.
// Results are ordered by number of stars on the public registry.
func (s *Service) Search(job *engine.Job) engine.Status {
if n := len(job.Args); n != 1 {
return job.Errorf("Usage: %s TERM", job.Name)
}
var (
term = job.Args[0]
metaHeaders = map[string][]string{}
authConfig = &AuthConfig{}
)

return job.Error(err)
}

}

if err != nil {
return job.Error(err)
}
results, err := r.SearchRepositories(term)
if err != nil {
return job.Error(err)
}
outs := engine.NewTable("star_count", 0)
for _, result := range results.Results {
out := &engine.Env{}

outs.Add(out)
}
outs.ReverseSort()
if _, err := outs.WriteListTo(job.Stdout); err != nil {
return job.Error(err)
}
return engine.StatusOK
