const DefaultEventerType = LogFile
DefaultEventerType is logfile when systemd is not present
Variables ¶

var ( // ErrEventTypeBlank indicates the event log found something done by podman // but it isn't likely an event ErrEventTypeBlank = errors.New("event type blank") // ErrEventNotFound indicates that the event was not found in the event log ErrEventNotFound = errors.New("unable to find event") )

var ErrNoJournaldLogging = errors.New("no support for journald logging")
ErrNoJournaldLogging indicates that there is no journald logging supported (requires libsystemd)
Functions ¶
func IsValidEventer ¶
IsValidEventer checks if the given string is a valid eventer type.
Types ¶
type Details ¶
type Details struct {
// ContainerInspectData includes the payload of the container's inspect
// data. Only set when events_container_create_inspect_data is set true
// in containers.conf.
ContainerInspectData string `json:",omitempty"`
// PodID is the ID of the pod associated with the container.
PodID string `json:",omitempty"`
// Attributes can be used to describe specifics about the event
// in the case of a container event, labels for example
Attributes map[string]string
}
Details describes specifics about certain events, specifically around container events
type Event ¶
type Event struct {
// ContainerExitCode is for storing the exit code of a container which can
// be used for "internal" event notification
ContainerExitCode *int `json:",omitempty"`
// ID can be for the container, image, volume, etc
ID string `json:",omitempty"`
// Image used where applicable
Image string `json:",omitempty"`
// Name where applicable
Name string `json:",omitempty"`
// Network is the network name in a network event
Network string `json:"network,omitempty"`
// Status describes the event that occurred
Status Status
// Time the event occurred
Time time.Time
// Type of event that occurred
Type Type
// Health status of the current container
HealthStatus string `json:"health_status,omitempty"`
// Healthcheck log of the current container
HealthLog string `json:"health_log,omitempty"`
// HealthFailingStreak log of the current container
HealthFailingStreak int `json:"health_failing_streak,omitempty"`
// Error code for certain events involving errors.
Error string `json:"error,omitempty"`
Details
}
Event describes the attributes of a libpod event
func (*Event) ToHumanReadable ¶
ToHumanReadable returns human-readable event as a formatted string
func (*Event) ToJSONString ¶
ToJSONString returns the event as a json'ified string
type EventLogFile ¶
type EventLogFile struct {
// contains filtered or unexported fields
}
EventLogFile is the structure for event writing to a logfile. It contains the eventer options and the event itself. Methods for reading and writing are also defined from it.
func (EventLogFile) Read ¶
func (e EventLogFile) Read(ctx context.Context, options ReadOptions) error
Reads from the log file
func (EventLogFile) String ¶
func (e EventLogFile) String() string
String returns a string representation of the logger
type EventToNull ¶
type EventToNull struct{}
EventToNull is an eventer type that does nothing. It is meant for unit tests only
func (EventToNull) Read ¶
func (e EventToNull) Read(ctx context.Context, options ReadOptions) error
Read does nothing and returns an error.
func (EventToNull) String ¶
func (e EventToNull) String() string
String returns a string representation of the logger
func (EventToNull) Write ¶
func (e EventToNull) Write(ee Event) error
Write eats the event and always returns nil
type Eventer ¶
type Eventer interface {
// Write an event to a backend
Write(event Event) error
// Read an event from the backend
Read(ctx context.Context, options ReadOptions) error
// String returns the type of event logger
String() string
}
Eventer is the interface for journald or file event logging
func NewEventer ¶
func NewEventer(options EventerOptions) (Eventer, error)
NewEventer creates an eventer based on the eventer type
type EventerOptions ¶
type EventerOptions struct {
// EventerType describes whether to use journald, file or memory
EventerType string
// LogFilePath is the path to where the log file should reside if using
// the file logger
LogFilePath string
// LogFileMaxSize is the default limit used for rotating the log file
LogFileMaxSize uint64
}
EventerOptions describe options that need to be passed to create an eventer
type EventerType ¶
type EventerType int
EventerType ...
const ( // LogFile indicates the event logger will be a logfile LogFile EventerType = iota // Journald indicates journald should be used to log events Journald EventerType = iota // Null is a no-op events logger. It does not read or write events. Null EventerType = iota )
func (EventerType) String ¶
func (et EventerType) String() string
String returns a string representation of EventerType
type ReadOptions ¶
type ReadOptions struct {
// EventChannel is the comm path back to user
EventChannel chan ReadResult
// Filters are key/value pairs that describe to limit output
Filters []string
// FromStart means you start reading from the start of the logs
FromStart bool
// Since reads "since" the given time
Since string
// Stream is follow
Stream bool
// Until reads "until" the given time
Until string
}
ReadOptions describe the attributes needed to read event logs
type ReadResult ¶ added in v5.3.0
type Status ¶
type Status string
Status describes the actual event action (stop, start, create, kill)
func StringToStatus ¶
StringToStatus converts a string to an Event Status
