func FindAdminAddress(configPath, configYaml string) (string, error)

FindAdminAddress parses the admin address from config sources.

func FindAdminAddressFromArgs(args []string) (string, error)

FindAdminAddressFromArgs extracts config sources from args and returns the admin address.

type Address struct {
	SocketAddress socketAddress `yaml:"socket_address"`
}

Address is the YAML representation of an envoy.config.core.v3.Address.

type Config struct {
	Admin           string // host:port format, empty if no admin
	StaticListeners []Listener
}

Config holds the admin and static listener metadata parsed from bootstrap YAML.

func ParseListeners(configPath, configYaml string) (*Config, error)

ParseListeners parses the admin address (if any) and all static listeners from config sources.

This mimics Envoy's config merging behavior from source/server/server.cc:

configPath is loaded first (if non-empty)
configYaml is merged on top via protobuf MergeFrom (if non-empty)
configYaml always wins for conflicting fields, regardless of which was specified first on CLI

For listeners with the same name, the later config wins (protobuf MergeFrom behavior).

type Listener struct {
	Name     string
	Address  string // host:port format
	Protocol string
	Filters  []filterInfo
}

Listener is a flattened view of a static listener parsed from bootstrap YAML.
