Functions

func RegisterTransformKind

func RegisterTransformKind(kind string)

RegisterTransformKind register new transformation in config validator

Types

type Bucket

type Bucket struct {
	Transform *Transform   `yaml:"transform,omitempty"`
	Storages  StorageTypes `yaml:"storages"`
	Keys      []S3Key      `yaml:"keys"`
	Name      string
}

Bucket describe single bucket entry in config

type Config

type Config struct {
	Buckets map[string]Bucket `yaml:"buckets"`
	Headers []HeaderYaml      `yaml:"headers"`
	Server  Server            `yaml:"server"`
	// contains filtered or unexported fields
}

Config contains configuration for buckets etc

Config should be used like singleton

func GetInstance

func GetInstance() *Config

GetInstance return single instance of Config object

func (*Config) BucketsByAccessKey

func (c *Config) BucketsByAccessKey(accessKey string) []Bucket

BucketsByAccessKey return list of buckets that have given accessKey

func (*Config) Load

func (c *Config) Load(filePath string) error

Load reads config data from file How configuration file should be formatted see README.md

func (*Config) LoadFromString

func (c *Config) LoadFromString(data string) error

LoadFromString parse configuration form string

type HeaderYaml

type HeaderYaml struct {
	StatusCodes []int             `yaml:"statusCodes"`
	Values      map[string]string `yaml:"values"`
}

HeaderYaml allow you to override response headers

type Preset

type Preset struct {
	Quality int    `yaml:"quality"`
	Format  string `yaml:"format"`
	Filters struct {
		Thumbnail *struct {
			Width  int    `yaml:"width"`
			Height int    `yaml:"height"`
			Mode   string `yaml:"mode"`
		} `yaml:"thumbnail,omitempty"`
		Interlace bool `yaml:"interlace"`
		Crop      *struct {
			Width   int    `yaml:"width"`
			Height  int    `yaml:"height"`
			Gravity string `yaml:"gravity"`
			Mode    string `yaml:"mode"`
		} `yaml:"crop,omitempty"`
		AutoRotate bool `yaml:"auto_rotate"`
		Grayscale  bool `yaml:"grayscale"`
		Strip      bool `yaml:"strip"`
		Blur       *struct {
			Sigma   float64 `yaml:"sigma"`
			MinAmpl float64 `yaml:"minAmpl"`
		} `yaml:"blur,omitempty"`
		Watermark *struct {
			Image    string  `yaml:"image"`
			Position string  `yaml:"position"`
			Opacity  float32 `yaml:"opacity"`
		} `yaml:"watermark,omitempty"`
		Rotate *struct {
			Angle int `yaml:"angle"`
		} `yaml:"rotate,omitempty"`
	} `yaml:"filters"`
}

Preset describe properties of transform preset

type S3Key

type S3Key struct {
	AccessKey       string `yaml:"accessKey"`
	SecretAccessKey string `yaml:"secretAccessKey"`
}

S3Key define credentials for s3 auth

type Server

type Server struct {
	InternalListen string   `yaml:"internalListen"`
	SingleListen   string   `yaml:"listen"`
	CacheSize      int64    `yaml:"cacheSize"`
	RequestTimeout int      `yaml:"requestTimeout"`
	QueueLen       int      `yaml:"queueLen"`
	Listen         []string `yaml:"listens"`
	Monitoring     string   `yaml:"monitoring"`
}

Server configure HTTP server

type Storage

type Storage struct {
	RootPath        string            `yaml:"rootPath,omitempty"`        // root path for local-* storage
	Kind            string            `yaml:"kind"`                      // type of storage from list ("local", "local-meta", "s3", "http", "noop")
	Url             string            `yaml:"url,omitempty"`             // Url for http storage
	Headers         map[string]string `yaml:"headers,omitempty"`         // request headers for http storage
	AccessKey       string            `yaml:"accessKey,omitempty"`       // access key for s3 storage
	SecretAccessKey string            `yaml:"secretAccessKey,omitempty"` // SecretAccessKey for s3 storage
	Region          string            `yaml:"region,omitempty"`          // region for s3 storage
	Endpoint        string            `yaml:"endpoint,omitempty"`        // endpoint for s3 storage
	PathPrefix      string            `yaml:"pathPrefix,omitempty"`      // prefix in path for all storage
	Bucket          string            `yaml:"bucket"`
	Hash            string            // unique hash for given storage
}

Storage contains information about kind of used storage

type StorageTypes

type StorageTypes map[string]Storage

StorageTypes contains map of storage for bucket

func (*StorageTypes) Basic

func (s *StorageTypes) Basic() Storage

Basic return storage that contains originals object

func (*StorageTypes) Get

func (s *StorageTypes) Get(name string) Storage

Get basic method for getting storage by name

func (*StorageTypes) Transform

func (s *StorageTypes) Transform() Storage

Transform return strorage in which we should storage processed objects

type Transform

type Transform struct {
	Path          string `yaml:"path"`
	ParentStorage string `yaml:"parentStorage"`
	ParentBucket  string `yaml:"parentBucket"`
	PathRegexp    *regexp.Regexp
