Types

type Config

type Config struct {
	Endpoint         string         `yaml:"endpoint"`
	Region           string         `yaml:"region"`
	BucketName       string         `yaml:"bucket_name"`
	SecretAccessKey  flagext.Secret `yaml:"secret_access_key"`
	AccessKeyID      string         `yaml:"access_key_id"`
	Insecure         bool           `yaml:"insecure" category:"advanced"`
	SignatureVersion string         `yaml:"signature_version" category:"advanced"`
	ForcePathStyle   bool           `yaml:"force_path_style" category:"advanced"`

	SSE  SSEConfig  `yaml:"sse"`
	HTTP HTTPConfig `yaml:"http"`
}

Config holds the config options for an S3 backend

func (*Config) RegisterFlags

func (cfg *Config) RegisterFlags(f *flag.FlagSet)

RegisterFlags registers the flags for s3 storage with the provided prefix

func (*Config) RegisterFlagsWithPrefix

func (cfg *Config) RegisterFlagsWithPrefix(prefix string, f *flag.FlagSet)

RegisterFlagsWithPrefix registers the flags for s3 storage with the provided prefix

func (*Config) Validate

func (cfg *Config) Validate() error

Validate config and returns error on failure

type HTTPConfig

type HTTPConfig struct {
	IdleConnTimeout       time.Duration `yaml:"idle_conn_timeout" category:"advanced"`
	ResponseHeaderTimeout time.Duration `yaml:"response_header_timeout" category:"advanced"`
	InsecureSkipVerify    bool          `yaml:"insecure_skip_verify" category:"advanced"`
	TLSHandshakeTimeout   time.Duration `yaml:"tls_handshake_timeout" category:"advanced"`
	ExpectContinueTimeout time.Duration `yaml:"expect_continue_timeout" category:"advanced"`
	MaxIdleConns          int           `yaml:"max_idle_connections" category:"advanced"`
	MaxIdleConnsPerHost   int           `yaml:"max_idle_connections_per_host" category:"advanced"`
	MaxConnsPerHost       int           `yaml:"max_connections_per_host" category:"advanced"`

	// Allow upstream callers to inject a round tripper
	Transport http.RoundTripper `yaml:"-"`
}

HTTPConfig stores the http.Transport configuration for the s3 minio client.

func (*HTTPConfig) RegisterFlagsWithPrefix

func (cfg *HTTPConfig) RegisterFlagsWithPrefix(prefix string, f *flag.FlagSet)

RegisterFlagsWithPrefix registers the flags for s3 storage with the provided prefix
