示例1: Namespace
// Namespace calls the nested method, and if an empty config error is returned
// it checks for the same default as kubectl - the value of POD_NAMESPACE or
// "default".
func (c defaultingClientConfig) Namespace() (string, bool, error) {
namespace, ok, err := c.nested.Namespace()
if err == nil {
return namespace, ok, nil
}
if !kclientcmd.IsEmptyConfig(err) {
return "", false, err
}
// TODO: can we inject the namespace as a file in the secret?
namespace = os.Getenv("POD_NAMESPACE")
if len(namespace) == 0 {
return api.NamespaceDefault, false, nil
}
return namespace, true, nil
}示例2: Namespace
// Namespace calls the nested method, and if an empty config error is returned
// it checks for the same default as kubectl - the value of POD_NAMESPACE or
// "default".
func (c defaultingClientConfig) Namespace() (string, bool, error) {
namespace, ok, err := c.nested.Namespace()
if err == nil {
return namespace, ok, nil
}
if !kclientcmd.IsEmptyConfig(err) {
return "", false, err
}
// This way assumes you've set the POD_NAMESPACE environment variable using the downward API.
// This check has to be done first for backwards compatibility with the way InClusterConfig was originally set up
if ns := os.Getenv("POD_NAMESPACE"); ns != "" {
return ns, true, nil
}
// Fall back to the namespace associated with the service account token, if available
if data, err := ioutil.ReadFile("/var/run/secrets/kubernetes.io/serviceaccount/namespace"); err == nil {
if ns := strings.TrimSpace(string(data)); len(ns) > 0 {
return ns, true, nil
}
}
return api.NamespaceDefault, false, nil
}示例3: ClientConfig
// ClientConfig returns a complete client config
func (c defaultingClientConfig) ClientConfig() (*kclient.Config, error) {
cfg, err := c.nested.ClientConfig()
if err == nil {
return cfg, nil
}
if !kclientcmd.IsEmptyConfig(err) {
return nil, err
}
// TODO: need to expose inClusterConfig upstream and use that
if icc, err := kclient.InClusterConfig(); err == nil {
glog.V(4).Infof("Using in-cluster configuration")
return icc, nil
}
return nil, fmt.Errorf(`No configuration file found, please login or point to an existing file:
1. Via the command-line flag --config
2. Via the KUBECONFIG environment variable
3. In your home directory as ~/.kube/config
To view or setup config directly use the 'config' command.`)
