There is no active work that I know of to put auditd in a container. It's 
libraries are used by many applications. So, I don't know what use it would 
be to containerize it.

And if you are asking if auditd can audit events in a container, I think that 
answer is also no.

I don't believe there is anything to prevent auditd from running within 
a container.  You can turn up and down the container to many different 
levels or security separation. There will be some security things that 
need to be turned off.

Running a contianer privileged will turn off almost everything form a 
security perspective, and then running with some of the namespaces 
shared with the host.

Something like

podman run --privileged --network=host --pid=host ... auditimage

Should work.

Later tightening up the security should also be possible, but you would 
need to know what auditd needs access to.

With all that said, I am not sure what you are trying to achieve by 
containerizing the audit daemon.

Audit currently requires access to the root userspace and pid
namespaces, so if the container shares those with the host, it should
run.

There are work items to address this, but they haven't been started in
ernest yet:

At the moment, auditd can be used inside a container only for aggregating 
logs from other systems. It cannot be used to get events relevant to the 
cotainer or the host OS. If you want to aggregate only, then set 
local_events=no in auditd.conf.

Container support is still under development.
