Golang ClientFlags.PostParse Examples

Example #1

File: cli.go Project: Raphaeljunior/docker

// NewDockerCli returns a DockerCli instance with IO output and error streams set by in, out and err.
// The key file, protocol (i.e. unix) and address are passed in as strings, along with the tls.Config. If the tls.Config
// is set the client scheme will be set to https.
// The client will be given a 32-second timeout (see https://github.com/docker/docker/pull/8035).

		in:      in,
		out:     out,
		err:     err,
		keyFile: clientFlags.Common.TrustKey,
	}

	cli.init = func() error {
		clientFlags.PostParse()
		cli.configFile = LoadDefaultConfigFile(err)
