# LogDriverVolumeConfiguration
<a name="API_LogDriverVolumeConfiguration"></a>

The configuration for a log driver volume in a daemon task definition. The volume contains the log files for each container on the container instance that uses the specified log driver in its `logConfiguration`. Containers that use a different log driver don't write log files to the volume.

For the `json-file` log driver, the volume has one directory for each container, named with the container ID. Each directory contains the container's log file, `<container-id>-json.log`, and any rotated log files. After a container stops and Amazon ECS removes it, Amazon ECS deletes the container's directory. Read the log files before the container is removed.
