can then use it as shown above at [Running synapse](#running-synapse).
## Building the image
If you need to build the image from a Synapse checkout, use the following `docker
build` command from the repo's root:
```
docker build -t matrixdotorg/synapse -f docker/Dockerfile .
```
You can choose to build a different docker image by changing the value of the `-f` flag to
point to another Dockerfile.

Attributes:

prev_group (int): Previously persisted state group. ``None`` for an

_state_group: The ID of the state group for this event. Note that state events
are persisted with a state group which includes the new event, so this is
effectively the state *after* the event in question.
app_service: FIXME
For a *rejected* state event, where the state of the rejected event is
ignored, this state_group should never make it into the
event_to_state_groups table. Indeed, inspecting this value for a rejected
state event is almost certainly incorrect.
For an outlier, where we don't have the state at the event, this will be
None.
Note that this is a private attribute: it should be accessed via
the ``state_group`` property.
state_group_before_event: The ID of the state group representing the state
of the room before this event.
If this is a non-state event, this will be the same as ``state_group``. If
it's a state event, it will be the same as ``prev_group``.
If ``state_group`` is None (ie, the event is an outlier),
``state_group_before_event`` will always also be ``None``.
prev_group: If it is known, ``state_group``'s prev_group. Note that this being
None does not necessarily mean that ``state_group`` does not have
a prev_group!
If the event is a state event, this is normally the same as ``prev_group``.
If ``state_group`` is None (ie, the event is an outlier), ``prev_group``
will always also be ``None``.
Note that this *not* (necessarily) the state group associated with
``_prev_state_ids``.
delta_ids: If ``prev_group`` is not None, the state delta between ``prev_group``
and ``state_group``.
app_service: If this event is being sent by a (local) application service, that
app service.
_current_state_ids: The room state map, including this event - ie, the state
in ``state_group``.
_current_state_ids (dict[(str, str), str]|None):
The current state map including the current event. None if outlier
or we haven't fetched the state from DB yet.

The current state map excluding the current event. None if outlier
or we haven't fetched the state from DB yet.
FIXME: what is this for an outlier? it seems ill-defined. It seems like
it could be either {}, or the state we were given by the remote
server, depending on $THINGS
Note that this is a private attribute: it should be accessed via
``get_current_state_ids``. _AsyncEventContext impl calculates this
on-demand: it will be None until that happens.
_prev_state_ids: The room state map, excluding this event - ie, the state
in ``state_group_before_event``. For a non-state
event, this will be the same as _current_state_events.
Note that it is a completely different thing to prev_group!
(type, state_key) -> event_id
FIXME: again, what is this for an outlier?
As with _current_state_ids, this is a private attribute. It should be
accessed via get_prev_state_ids.
