NAME

podman-events - Monitor Podman events

SYNOPSIS

podman events [options]

podman system events [options]

DESCRIPTION

Monitor and print events that occur in Podman. Each event includes a timestamp, a type, a status, name (if applicable), and image (if applicable). The default logging mechanism is journald. This can be changed in containers.conf by changing the events_logger value to file. Only file and journald are accepted. A none logger is also available, but this logging mechanism completely disables events; nothing is reported by podman events.

By default, streaming mode is used, printing new events as they occur. Previous events can be listed via --since and --until.

The container event type reports the follow statuses:

  • attach

  • checkpoint

  • cleanup

  • commit

  • connect

  • create

  • died

  • disconnect

  • exec

  • exec_died

  • exited

  • export

  • import

  • init

  • kill

  • mount

  • pause

  • prune

  • remove

  • rename

  • restart

  • restore

  • start

  • stop

  • sync

  • unmount

  • unpause

The pod event type reports the follow statuses:

  • create

  • kill

  • pause

  • remove

  • start

  • stop

  • unpause

The image event type reports the following statuses:

  • loadFromArchive,

  • mount

  • pull

  • push

  • remove

  • save

  • tag

  • unmount

  • untag

The system type reports the following statuses:

  • refresh

  • renumber

The volume type reports the following statuses:

  • create

  • prune

  • remove

Verbose Create Events

Setting events_container_create_inspect_data=true in containers.conf(5) instructs Podman to create more verbose container-create events which include a JSON payload with detailed information about the containers. The JSON payload is identical to the one of podman-container-inspect(1). The associated field in journald is named PODMAN_CONTAINER_INSPECT_DATA.

OPTIONS

--filter, -f=filter

Filter events that are displayed. They must be in the format of “filter=value”. The following filters are supported:

Filter

Description

container

[Name or ID] Container’s name or ID

event

event_status (described above)

image

[Name or ID] Image name or ID

label

[key=value] label

pod

[Name or ID] Pod name or ID

volume

[Name or ID] Volume name or ID

type

Event_type (described above)

In the case where an ID is used, the ID may be in its full or shortened form. The “die” event is mapped to “died” for Docker compatibility.

--format

Format the output to JSON Lines or using the given Go template.

Placeholder

Description

.Attributes …

created_at, _by, labels, and more (map[])

.ContainerExitCode

Exit code (int)

.ContainerInspectData

Payload of the container’s inspect

.HealthStatus

Health Status (string)

.ID

Container ID (full 64-bit SHA)

.Image

Name of image being run (string)

.Name

Container name (string)

.Network

Name of network being used (string)

.PodID

ID of pod associated with container, if any

.Status

Event status (e.g., create, start, died, …)

.Time …

Event timestamp (string)

.ToHumanReadable bool

If true, truncates CID in output

.Type

Event type (e.g., image, container, pod, …)

--help

Print usage statement.

--no-trunc

Do not truncate the output (default true).

--since=timestamp

Show all events created since the given timestamp

--stream

Stream events and do not exit after reading the last known event (default true).

--until=timestamp

Show all events created until the given timestamp

The since and until values can be RFC3339Nano time stamps or a Go duration string such as 10m, 5h. If no since or until values are provided, only new events are shown.

JOURNALD IDENTIFIERS

The journald events-backend of Podman uses the following journald identifiers. You can use the identifiers to filter Podman events directly with journalctl.

PODMAN_TYPE

The event type as described above

PODMAN_TIME

The time stamp when the event was written

PODMAN_NAME

Name of the event object (e.g., container, image)

PODMAN_ID

PODMAN_EXIT_CODE

Exit code of the container

PODMAN_POD_ID

Pod ID of the container

PODMAN_LABELS
