Constants

const Name = "bundle"

Name identifies the plugin on manager.

Types

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

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

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

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.

type ConfigBuilder

type ConfigBuilder struct {
	// contains filtered or unexported fields
}

ConfigBuilder assists in the construction of the plugin configuration.

func NewConfigBuilder

func NewConfigBuilder() *ConfigBuilder

NewConfigBuilder returns a new ConfigBuilder to build and parse the bundle config

func (*ConfigBuilder) Parse

func (b *ConfigBuilder) Parse() (*Config, error)

Parse validates the config and injects default values for the defined `bundles`.

func (*ConfigBuilder) WithBytes

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

WithBytes sets the raw bundle config

func (*ConfigBuilder) WithKeyConfigs

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

WithKeyConfigs sets the public keys to verify a signed bundle

func (*ConfigBuilder) WithServices

func (b *ConfigBuilder) WithServices(services []string) *ConfigBuilder

WithServices sets the services that implement control plane APIs

func (*ConfigBuilder) WithTriggerMode

func (b *ConfigBuilder) WithTriggerMode(trigger *plugins.TriggerMode) *ConfigBuilder

WithTriggerMode sets the plugin trigger mode

type Loader

type Loader interface {
	Start(context.Context)
	Stop(context.Context)
	Trigger(context.Context) error
	SetCache(string)
	ClearCache()
}

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

type Plugin

type Plugin struct {
	// contains filtered or unexported fields
}

Plugin implements bundle activation.

func Lookup

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

New returns a new Plugin with the given config.

func (*Plugin) Config

func (p *Plugin) Config() *Config

Config returns the plugins current configuration

func (*Plugin) Loaders

func (p *Plugin) Loaders() map[string]Loader

Loaders returns the map of bundle loaders configured on this plugin.

func (*Plugin) Reconfigure

func (p *Plugin) Reconfigure(ctx context.Context, config interface{})

Reconfigure notifies the plugin that it's configuration has changed. Any bundle configs that have changed or been added/removed will take affect.

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

func (p *Plugin) RegisterBulkListener(name interface{}, listener func(map[string]*Status))

RegisterBulkListener registers a listener to receive bulk (aggregated) status updates. The name must be comparable.

func (*Plugin) Start

func (p *Plugin) Start(ctx context.Context) error

Start runs the plugin. The plugin will periodically try to download bundles from the configured service. When a new bundle is downloaded, the data and policies are extracted and inserted into storage.

func (*Plugin) Stop

func (p *Plugin) Stop(ctx context.Context)

Stop stops the plugin.

func (*Plugin) Trigger

func (p *Plugin) Trigger(ctx context.Context) error

Trigger triggers a bundle download on all configured bundles.

func (*Plugin) Unregister

func (p *Plugin) Unregister(name interface{})

Unregister a listener to stop receiving status updates.

func (*Plugin) UnregisterBulkListener

func (p *Plugin) UnregisterBulkListener(name interface{})

UnregisterBulkListener unregisters a listener to stop receiving aggregated status updates.

type Source

type Source struct {
	download.Config

	Service        string                     `json:"service"`
	Resource       string                     `json:"resource"`
	Signing        *bundle.VerificationConfig `json:"signing"`
	Persist        bool                       `json:"persist"`
	SizeLimitBytes int64                      `json:"size_limit_bytes"`
}

Source is a configured bundle source to download bundles from

type Status

type Status struct {
	Name                     string          `json:"name"`
	ActiveRevision           string          `json:"active_revision,omitempty"`
	LastSuccessfulActivation time.Time       `json:"last_successful_activation,omitempty"`
	Type                     string          `json:"type,omitempty"`
	Size                     int             `json:"size,omitempty"`
	LastSuccessfulDownload   time.Time       `json:"last_successful_download,omitempty"`
	LastSuccessfulRequest    time.Time       `json:"last_successful_request,omitempty"`
	LastRequest              time.Time       `json:"last_request,omitempty"`
	Code                     string          `json:"code,omitempty"`
	Message                  string          `json:"message,omitempty"`
	Errors                   []error         `json:"errors,omitempty"`
	Metrics                  metrics.Metrics `json:"metrics,omitempty"`
	HTTPCode                 json.Number     `json:"http_code,omitempty"`
}

Status represents the status of processing a bundle.

func (*Status) SetActivateSuccess

func (s *Status) SetActivateSuccess(revision string)

SetActivateSuccess updates the status object to reflect a successful activation.

func (*Status) SetBundleSize

func (s *Status) SetBundleSize(size int)

func (*Status) SetDownloadSuccess

func (s *Status) SetDownloadSuccess()

SetDownloadSuccess updates the status object to reflect a successful download.

func (*Status) SetError

func (s *Status) SetError(err error)

SetError updates the status object to reflect a failure to download or activate. If err is nil, the error status is cleared.

func (*Status) SetRequest

func (s *Status) SetRequest()

SetRequest updates the status object to reflect a download attempt.
