## How to configure logging

By default, ZooKeeper redirects stdout/stderr outputs to the console. You can redirect to a file located in `/logs` by passing environment variable `ZOO_LOG4J_PROP` as follows:
By default, ZooKeeper redirects stdout/stderr outputs to the console. Since 3.8 ZooKeeper is shipped with [LOGBack](https://logback.qos.ch/) as the logging backend. The ZooKeeper default `logback.xml` file resides in the `/conf` directory. To override default logging configuration mount your custom config as a volume:

```console
$ docker run --name some-zookeeper --restart always -e ZOO_LOG4J_PROP="INFO,ROLLINGFILE" %%IMAGE%%
$ docker run --name some-zookeeper --restart always -d -v $(pwd)/logback.xml:/conf/logback.xml %%IMAGE%%
```

This will write logs to `/logs/zookeeper.log`. Check [ZooKeeper Logging](https://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_logging) for more details.
