This shows all the containers that have exited with status of '0'
##### Killed containers
You can use a filter to locate containers that exited with status of `137` meaning a `SIGKILL(9)` killed them.
$ docker ps -a --filter 'exited=137'
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

Any of these events a result in `137` status:
* the `init` process of the container is killed manually
* `docker kill` kills the container
* Docker daemon restarts which kills all old running containers
