:description: Running Neo4j in a Docker container using Docker Compose
2+
[[docker-compose-neo4j-standalone]]

= Deploy a Neo4j standalone server using Docker Compose
4+
5+
You can deploy a Neo4j standalone server using Docker Compose by defining the container configuration in a _docker-compose.yml_ file and authenticating with basic authentication or Docker secrets.

== Deploy a Neo4j server using basic authentication mechanism
9+
10+
Before you start, verify that you have installed Docker Compose.
11+
For more information, see the https://docs.docker.com/compose/install/[Install Docker Compose official documentation].
12+
13+
. Create a project folder where you will store your _docker-compose.yml_ file and run your Neo4j server.
14+
. Prepare your _docker-compose.yml_ file using the following example.
15+
For more information, see the Docker Compose official documentation on https://docs.docker.com/compose/compose-file/#service-configuration-reference[Docker Compose specification].

50+
== Deploy a Neo4j server with Docker secrets
51+
52+
It is advisable not to store sensitive information, such as the database username and password, in the _docker-compose.yml_ file.
53+
You can instead store your credentials in files and use them in your _docker-compose.yml_ file without exposing their values.
54+
55+
. Create a file, for example, _neo4j_auth.txt_, containing the username and password for the Neo4j server to be used as a Docker secret.

<2> Path to the file where the value for the `NEO4J_AUTH` environment variable can be found.

<3> The name of the secret, for example `neo4j_auth_file`.
90+
<4> Path to the _neo4j_auth.txt_ file.
91+
<5> The name of the secret in the `neo4j` service.
92+
+
93+
[WARNING]
94+
====
95+
The secret value overrides the equivalent environment variable if they are both defined.
96+
So, for example, if you also define an environment variable `NEO4J_AUTH=neo4j/your_other_password` in the `environment` section of the `neo4j` service, the value of `NEO4J_AUTH_FILE` will be the one used.
97+

. Deploy your Neo4j server by running `docker-compose up` from your project folder.
