To recover the node key and data directory from the Docker container:
* Save the node key in the [`key` file](https://docs.pantheon.pegasys.tech/en/latest/Configuring-Besu/Node-Keys/#node-private-key) in the data
directory or specify the location using the [`--node-private-key` option](https://docs.pantheon.pegasys.tech/en/latest/Configuring-Besu/Node-Keys/#specifying-a-custom-node-private-key-file).
* Specify the `<destination_directory` as a [volume for the data directory](https://docs.pantheon.pegasys.tech/en/latest/Getting-Started/Run-Docker-Image/#data-directory).

From v0.8.3, incoming HTTP requests are only accepted from hostnames specified using the `--host-whitelist` command-line option. If not specified, the default value for `--host-whitelist` is `localhost`.
If using the URL `http://127.0.0.1` to make JSON-RPC calls, use `--host-whitelist` to specify the hostname `127.0.0.1` or update the hostname to `localhost`.
Specify `*` or `all` for `--host-whitelist` to effectively disable host protection and replicate pre-v0.8.3 behavior. This is not recommended for production code.
