Functions

func AddFlags

func AddFlags(fs *flag.FlagSet, f *Flags)

AddFlags adds the command line flags for the agent.

func DefaultRPCProtocol

func DefaultRPCProtocol() (int, error)

func FormatFrom

func FormatFrom(name string) string

func TranslateKeys

func TranslateKeys(v map[string]interface{}, dict map[string]string)

TranslateKeys recursively translates all keys from m in-place to their canonical form as defined in dict which maps an alias name to the canonical name. If m already has a value for the canonical name then that one is used and the value for the alias name is discarded. Alias names are matched case-insensitive.

Example:

m = TranslateKeys(m, map[string]string{"snake_case": "CamelCase"})

If the canonical string provided is the empty string, the effect is to stop recursing into any key matching the left hand side. In this case the left hand side must use periods to specify a full path e.g. `connect.proxy.config`. The path must be the canonical key names (i.e. CamelCase) AFTER translation so ExecMode not exec_mode. These are still match in a case-insensitive way.

This is needed for example because parts of the Service Definition are "opaque" maps of metadata or config passed to another process or component. If we allow translation to recurse we might mangle the "opaque" keys given where the clash with key names in other parts of the definition (and they do in practice with deprecated managed proxy upstreams) :sob:

Example:

m - TranslateKeys(m, map[string]string{
  "foo_bar": "FooBar",
  "widget.config": "",
  // Assume widgets is an array, this will prevent recursing into any
  // item's config field
  "widgets.config": "",
})

type Builder

type Builder struct {
	// Flags contains the parsed command line arguments.
	Flags Flags

	// Head, Sources, and Tail are used to manage the order of the
	// config sources, as described in the comments above.
	Head    []Source
	Sources []Source
	Tail    []Source

	// Warnings contains the warnings encountered when
	// parsing the configuration.
	Warnings []string

	// Hostname returns the hostname of the machine. If nil, os.Hostname
	// is called.
	Hostname func() (string, error)

	// GetPrivateIPv4 and GetPublicIPv6 return suitable default addresses
	// for cases when the user doesn't supply them.
	GetPrivateIPv4 func() ([]*net.IPAddr, error)
	GetPublicIPv6  func() ([]*net.IPAddr, error)
	// contains filtered or unexported fields
}

Builder constructs a valid runtime configuration from multiple configuration sources.

To build the runtime configuration first call Build() which merges the sources in a pre-defined order, converts the data types and structures into their final form and performs the syntactic validation.

The sources are merged in the following order:

* default configuration
* config files in alphabetical order
* command line arguments

The config sources are merged sequentially and later values overwrite previously set values. Slice values are merged by concatenating the two slices. Map values are merged by over- laying the later maps on top of earlier ones.

Then call Validate() to perform the semantic validation to ensure that the configuration is ready to be used.

Splitting the construction into two phases greatly simplifies testing since not all pre-conditions have to be satisfied when performing syntactical tests.

func NewBuilder

func NewBuilder(flags Flags) (*Builder, error)

NewBuilder returns a new configuration builder based on the given command line flags.

func (*Builder) Build

func (b *Builder) Build() (rt RuntimeConfig, err error)

Build constructs the runtime configuration from the config sources and the command line flags. The config sources are processed in the order they were added with the flags being processed last to give precedence over the other sources. If the error is nil then warnings can still contain deprecation or format warnings that should be presented to the user.

func (*Builder) BuildAndValidate

func (b *Builder) BuildAndValidate() (RuntimeConfig, error)

func (*Builder) ReadFile

func (b *Builder) ReadFile(path string) (Source, error)

ReadFile parses a JSON or HCL config file and appends it to the list of config sources.

func (*Builder) ReadPath

func (b *Builder) ReadPath(path string) ([]Source, error)

ReadPath reads a single config file or all files in a directory (but not its sub-directories) and appends them to the list of config sources.

func (*Builder) Validate

func (b *Builder) Validate(rt RuntimeConfig) error

Validate performs semantical validation of the runtime configuration.

Config defines the format of a configuration file in either JSON or HCL format.

It must contain only pointer values, slices and maps to support standardized merging of multiple Config structs into one.

Since this is the format which users use to specify their configuration it should be treated as an external API which cannot be changed and refactored at will since this will break existing setups.

func Merge

func Merge(files ...Config) Config

Merge recursively combines a set of config file structures into a single structure according to the following rules:

* only values of type struct, slice, map and pointer to simple types are allowed. Other types panic. * when merging two structs the result is the recursive merge of all fields according to the rules below * when merging two slices the result is the second slice appended to the first * when merging two maps the result is the second map overlaid on the first * when merging two pointer values the result is the second value if it is not nil, otherwise the first

func Parse

func Parse(data string, format string) (c Config, err error)

Parse parses a config fragment in either JSON or HCL format.

RuntimeConfig specifies the configuration the consul agent actually uses. Is is derived from one or more Config structures which can come from files, flags and/or environment variables.

func DefaultRuntimeConfig

type Source

type Source struct {
	Name   string
	Format string

}

func DefaultConsulSource

func DefaultConsulSource() Source

DefaultConsulSource returns the default configuration for the consul agent. This should be merged in the tail since these values are not user configurable.

func DefaultEnterpriseSource

func DefaultEnterpriseSource() Source

DefaultEnterpriseSource returns the consul agent configuration for the enterprise mode. This should be merged in the tail after the DefaultConsulSource.

func DefaultSource

func DefaultSource() Source

DefaultSource is the default agent configuration. This needs to be merged first in the head. todo(fs): The values are sourced from multiple sources. todo(fs): IMO, this should be the definitive default for all configurable values todo(fs): and whatever is in here should clobber every default value. Hence, no sourcing.

func DefaultVersionSource

func DefaultVersionSource() Source

DefaultVersionSource returns the version config source for the embedded version numbers.

func DevConsulSource

func DevConsulSource() Source

DevConsulSource returns the consul agent configuration for the dev mode. This should be merged in the tail after the DefaultConsulSource.

func DevSource

func DevSource() Source

DevSource is the additional default configuration for dev mode. This should be merged in the head after the default configuration.

func NonUserSource

func NonUserSource() Source

NonUserSource contains the values the user cannot configure. This needs to be merged in the tail.

func VersionSource

func VersionSource(rev, ver, verPre string) Source

VersionSource creates a config source for the version parameters. This should be merged in the tail since these values are not user configurable.
