+# Advanced Configuration
+
+The all-in-one image ships with sensible defaults baked into [`conf/ozone-site.xml`](conf/ozone-site.xml) and [`conf/core-site.xml`](conf/core-site.xml). These cover a single-DataNode cluster with replication of 1.
+
+For one-off tweaks at runtime, you can override individual properties without rebuilding the image by mounting a custom config file.
+
+## Override via mounted config
+
+Mounting a file over `/etc/hadoop/ozone-site.xml` fully replaces the baked-in copy, so start by copying [`conf/ozone-site.xml`](conf/ozone-site.xml), edit the properties you want to change, then mount your version:
+
+```bash
+docker run -d \
+  --name ozone \
+  -p 9878:9878 -p 9888:9888 \
+  -v "$(pwd)/my-ozone-site.xml:/etc/hadoop/ozone-site.xml:ro" \
+  -v ozone-metadata:/data/metadata \
+  -v ozone-hdds:/data/hdds \
+  -v ozone-logs:/var/log/hadoop \
+  apache/ozone:all-in-one
+```
