I hope that my Spanish is sufficient to understand your question ^^ (please, consider to write in english to receive a maximum of help).
Neo4j (in the enterprise version) has a cluster mechanism called
HA (High Avaibility) that can do what you want (it's a Master/Slave architecture). You can find all the information about how to setup a HA cluster here : https://neo4j.com/docs/operations-manual/current/ha-cluster/tutorial/setup-cluster/
For your information, a cluster in Neo4j requires a minima of 3 servers.
Neo4j has an other cluster architecture that is called
Causal Clustering, and I recommend you to use it instead of the
HA mode (HA is just maintained, it will not evolved).
I suggest you to read the documentation about the clustering architecture of Neo4j : https://neo4j.com/docs/operations-manual/current/clustering/
NB: To launch a Causal Cluster with Docker, take a look at https://neo4j.com/docs/operations-manual/current/installation/docker/#docker-cc
