Functions ¶
func ConvertNodeToXDSNode ¶
ConvertNodeToXDSNode creates an Envoy node descriptor from Istio node descriptor.
func ConvertXDSNodeToNode ¶
ConvertXDSNodeToNode parses Istio node descriptor from an Envoy node descriptor, using only typed metadata.
func GetEffectiveTemplatePath ¶
func GetEffectiveTemplatePath(pc *model.NodeMetaProxyConfig) string
GetEffectiveTemplatePath gets the template file that should be used for bootstrap
func GetNodeMetaData ¶
func GetNodeMetaData(options MetadataOptions) (*model.Node, error)
GetNodeMetaData function uses an environment variable contract ISTIO_METAJSON_* env variables contain json_string in the value. The name of variable is ignored. ISTIO_META_* env variables are passed through
func ParseDownwardAPI ¶
ParseDownwardAPI parses fields which are stored as format `%s=%q` back to a map
func SetIstioVersion ¶
func SetIstioVersion(meta *model.BootstrapNodeMetadata) *model.BootstrapNodeMetadata
Types ¶
type Config ¶
type Config struct {
*model.Node
// CompliancePolicy to decouple the environment variable dependency.
CompliancePolicy string
LogAsJSON bool
}
Config for creating a bootstrap file.
type Instance ¶
type Instance interface {
// WriteTo writes the content of the Envoy bootstrap to the given writer.
WriteTo(templateFile string, w io.Writer) error
// CreateFile generates an Envoy bootstrap file.
CreateFile() (string, error)
}
Instance of a configured Envoy bootstrap writer.
type MetadataOptions ¶
type MetadataOptions struct {
Envs []string
Platform platform.Environment
InstanceIPs []string
StsPort int
ID string
ProxyConfig *meshAPI.ProxyConfig
PilotSubjectAltName []string
CredentialSocketExists bool
XDSRootCert string
OutlierLogPath string
EnvoyStatusPort int
EnvoyPrometheusPort int
ExitOnZeroActiveConnections bool
MetadataDiscovery bool
// contains filtered or unexported fields
}
