本文整理汇总了Golang中github.com/coreos/rkt/Godeps/_workspace/src/github.com/appc/spec/schema/types.Environment类的典型用法代码示例。如果您正苦于以下问题：Golang Environment类的具体用法？Golang Environment怎么用？Golang Environment使用的例子？那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。

在下文中一共展示了Environment类的5个代码示例，这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞，您的评价将有助于我们的系统推荐出更棒的Golang代码示例。

示例1: writeEnvFile

// writeEnvFile creates an environment file for given app name, the minimum
// required environment variables by the appc spec will be set to sensible
// defaults here if they're not provided by env.
func writeEnvFile(p *stage1commontypes.Pod, env types.Environment, appName types.ACName, privateUsers string) error {
	ef := bytes.Buffer{}

	for dk, dv := range defaultEnv {
		if _, exists := env.Get(dk); !exists {
			fmt.Fprintf(&ef, "%s=%s\000", dk, dv)
		}
	}

	for _, e := range env {
		fmt.Fprintf(&ef, "%s=%s\000", e.Name, e.Value)
	}

	uidRange := uid.NewBlankUidRange()
	if err := uidRange.Deserialize([]byte(privateUsers)); err != nil {
		return err
	}

	envFilePath := EnvFilePath(p.Root, appName)
	if err := ioutil.WriteFile(envFilePath, ef.Bytes(), 0644); err != nil {
		return err
	}

	if uidRange.Shift != 0 && uidRange.Count != 0 {
		if err := os.Chown(envFilePath, int(uidRange.Shift), int(uidRange.Shift)); err != nil {

示例2: writeEnvFile

// writeEnvFile creates an environment file for given app id
// the minimum required environment variables by the appc spec will be set to sensible
// defaults here if they're not provided by env.
func (p *Pod) writeEnvFile(env types.Environment, id types.Hash) error {

示例3: MergeEnvs

// MergeEnvs amends appEnv setting variables in setEnv before setting anything new from os.Environ if inheritEnv = true
// setEnv is expected to be in the os.Environ() key=value format
func MergeEnvs(appEnv *types.Environment, inheritEnv bool, setEnv []string) {
	for _, ev := range setEnv {
		pair := strings.SplitN(ev, "=", 2)
		appEnv.Set(pair[0], pair[1])
	}
