This container is meant to output Docker journald logs in json format so that they can be shipped to a log collector. This allows for local logging to still function while also outputting the logs to a consumable format for most log forwarders.

1. Clone this repo
2. Create /etc/docker/daemon.json with the following contents:

{
    "log-driver": "journald"
}

3. Restart the Docker daemon for changes to take effect
4. docker stack deploy -c docker-compose.yml logbook
5. Set your log forwarder to use logbook_docker-journal as an external volume or bind mount /var/lib/docker/volumes/logbook_docker-journal/_data:/logs

1. Refer to the README in this repository for extending to use with the ELK stack.

The environment variables LOG_SIZE and NUM_SEGM can be specified in the compose file to define the default log size, and how many segments to keep.
