If you are planning to import the entire planet or you are running into memory errors then you may want to enable the `--flat-nodes` option for osm2pgsql. This option takes a path to a file that must be persisted so we should first set up a volume with the right permissions:
```
docker run -it -v openstreetmap-nodes:/nodes --entrypoint=bash overv/openstreetmap-tile-server
$ chown renderer:renderer -R /nodes
$ exit
```
You can then use it during the import process as follows:
```
docker run \
-v /absolute/path/to/luxembourg.osm.pbf:/data.osm.pbf \
-v openstreetmap-nodes:/nodes \
-v openstreetmap-data:/var/lib/postgresql/10/main \
-e OSM2PGSQL_EXTRA_ARGS=--flat-nodes \
-e "OSM2PGSQL_EXTRA_ARGS=--flat-nodes /nodes/flat_nodes.bin" \
overv/openstreetmap-tile-server \
import
```
