+
+================================
+Using a dedicated Docker network
+================================
+
+Use this method to avoid having to expose PostreSQL port to the host's network
+or if you have other PostgreSQL instances but still want to use the default
+port of 5432 for this installation.
+
+#. Create the network::
+
+       docker network create mayan
+
+#. Launch the PostgreSQL container with the network option and remove the
+   port binding (``-p 5432:5432``)::
+
+       docker run \
+       -d \
+       --name mayan-edms-postgres \
+       --network=mayan \
+       --restart=always \
+       -e POSTGRES_USER=mayan \
+       -e POSTGRES_DB=mayan \
+       -e POSTGRES_PASSWORD=mayanuserpass \
+       -v /docker-volumes/mayan-edms/postgres:/var/lib/postgresql/data \
+       |DOCKER_POSTGRES_IMAGE_VERSION|
+
+#. Launch the Redis container with the network option and remove the port
+   binding (``-p 6379:6379``)::
+
+       docker run \
+       -d \
+       --name mayan-edms-redis \
+       --network=mayan \
+       |DOCKER_REDIS_IMAGE_VERSION| \
+       redis-server \
+       --databases \
+       "2" \
+       --maxmemory-policy \
+       allkeys-lru \
+       --save \
+       ""
+
+#. Launch the Mayan EDMS container with the network option and change the
+   database hostname to the PostgreSQL container name (``mayan-edms-postgres``)
+   instead of the IP address of the Docker host (``172.17.0.1``)::
+
+       docker run \
+       -d \
+       --name mayan-edms \
+       --network=mayan \
+       --restart=always \
