This commit adds the "secret" Event type and emits "create" and "remove" events for this Event type when Secret is created or removed. This can be used for example by podman interfaces to view and manage secrets. Fixes: #24030 Signed-off-by: Jan Kaluza <jkaluza@redhat.com>

## 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
|

* exec_died
|
|
* exited
|
|
* export
|
|
* import

|
* create
|
|
* kill
|
|
* pause
|
|
* remove
|
|
* start
|
|
* stop
|
|
* unpause
|
|
|
|
The *image* event type reports the following statuses:
|
|
* loadFromArchive,
|
|
* mount
|
|
* pull
|
|
* pull-error
|
|
* 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
|
|
|
|
The *secret* type reports the following statuses:
|
|
* create
|
|
* 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.
|
|
|
|

|
|
|
|
#### **--until**=*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 | ID of the event object (e.g., container, image) |
|
|
| PODMAN_EXIT_CODE | Exit code of the container |
|
|
| PODMAN_POD_ID | Pod ID of the container |
|
|
| PODMAN_LABELS | Labels of the container |
