type Config

type Config struct {
	download.Config // Deprecated: Use `Bundles` map instead

	Bundles map[string]*Source

	Name    string  `json:"name"`    // Deprecated: Use `Bundles` map instead
	Service string  `json:"service"` // Deprecated: Use `Bundles` map instead
	Prefix  *string `json:"prefix"`  // Deprecated: Use `Bundles` map instead

Config represents the configuration of the plugin. The Config can define a single bundle source or a map of `Source` objects defining where/how to download bundles. The older single bundle configuration is deprecated and will be removed in the future in favor of the `Bundles` map.

func ParseBundlesConfig added in v0.13.0

func ParseBundlesConfig(config []byte, services []string) (*Config, error)

ParseBundlesConfig validates the config and injects default values for the defined `bundles`. This expects a map of bundle names to resource configurations.

func ParseConfig deprecated added in v0.10.2

func ParseConfig(config []byte, services []string) (*Config, error)

ParseConfig validates the config and injects default values. This is for the legacy single bundle configuration. This will add the bundle to the `Bundles` map to provide compatibility with newer clients. Deprecated: Use `ParseBundlesConfig` with `bundles` OPA config option instead

func (*Config) IsMultiBundle added in v0.13.0

func (c *Config) IsMultiBundle() bool

IsMultiBundle returns whether or not the config is the newer multi-bundle style config that uses `bundles` instead of top level bundle information. If/when we drop support for the older style config we can remove this too.

func (b *ConfigBuilder) WithBytes(config []byte) *ConfigBuilder

WithBytes sets the raw bundle config

func (*ConfigBuilder) WithKeyConfigs added in v0.22.0

func (b *ConfigBuilder) WithKeyConfigs(keys map[string]*keys.Config) *ConfigBuilder

WithKeyConfigs sets the public keys to verify a signed bundle

func (*ConfigBuilder) WithServices added in v0.22.0

type Loader added in v0.32.0

type Loader interface {
	Trigger(context.Context) error

Loader defines the interface that the bundle plugin uses to control bundle loading via HTTP, disk, etc.

type Plugin

	// contains filtered or unexported fields

Plugin implements bundle activation.

func Lookup added in v0.10.2

func Lookup(manager *plugins.Manager) *Plugin

Lookup returns the bundle plugin registered with the manager.

func New

func New(parsedConfig *Config, manager *plugins.Manager) *Plugin

func (*Plugin) Register

func (p *Plugin) Register(name interface{}, listener func(Status))

Register a listener to receive status updates. The name must be comparable. The listener will receive a status update for each bundle configured, they are not going to be aggregated. For all status updates use `RegisterBulkListener`.

func (*Plugin) RegisterBulkListener added in v0.13.0
