Neo4j standalone instance (VM-based)
You can deploy a Neo4j standalone instance using an image from the GCP Marketplace.
You know how to run and operate Neo4j locally.
You know how to access cloud-hosted Neo4j from your application. See the Driver Manual.
You have installed and set up Google Cloud SDK to be able to use the
You have authenticated your gcloud CLI, to interact with your GCP projects.
Create a firewall rule to be able to access your instance when it is launched:
gcloud compute firewall-rules create allow-neo4j-bolt-http-https \ (1) --allow tcp:7473,tcp:7474,tcp:7687 \ (2) --source-ranges 0.0.0.0/0 \ (3) --target-tags neo4j (4)
|1||Create a firewall rule with the name
|2||Allow traffic on ports:
|3||The ranges, provided with the
When you launch your instance, you have to apply that tag to it.
List all available Neo4j public images.
The images are published in a GCP project called
launcher-public, so by listing images in that project, you can see what is available.
gcloud compute images list --project launcher-public
launcher-publicimages — filtered on Neo4j 4.X versions
gcloud compute images list --project launcher-public | grep --extended-regexp "neo4j-(community|enterprise)-1-4-.*"
For example, the image
neo4j-enterprise-1-4-2-2-apocincludes Neo4j Enterprise 4.2.2 with the APOC plugin.
Create a new instance.
You create and launch an instance by using the following
gcloud config set project <project-id> (1) gcloud compute instances create my-neo4j-instance --image-project launcher-public \ (2) --image <neo4j-image-name> \ (3) --tags neo4j (4)
1 Set your project configuration to ensure you know where you are launching your instance. 2 Launch an image found in the provided public project
<neo4j-image-name>with the image name you want to launch.
--tagsargument allows you to configure the correct network permissions.
By default, Google blocks all external access to the network services unless you open them.
When the launch is successful, you get the following result:Example output
Created [https://www.googleapis.com/compute/v1/projects/testbed-187316/zones/us-east1-b/instances/my-neo4j-instance]. NAME ZONE MACHINE_TYPE PREEMPTIBLE INTERNAL_IP EXTERNAL_IP STATUS my-neo4j-instance europe-north1-a n1-standard-1 192.0.2.0 203.0.113.0 RUNNING
Note the IP address in the
EXTERNAL_IPcolumn, this is for the Neo4j server.
https://[EXTERNAL_IP]:7473/browser, log in with the default username
neo4j and password
neo4j, and change the password, when prompted.
Neo4j 3.X versions include a self-signed certificate for TLS. Because you do not have a hostname or a valid SSL certificate configured by default, your browser will warn you that the certificate is not trusted.
Neo4j 4.X versions do not include any certificate for TLS. You can configure the certificate later.
You can run the following command to SSH into the instance:
gcloud compute ssh my-neo4j-instance
Inside the VM, you can check the status of the
sudo systemctl status neo4j

You can run the following command to delete your instance:
