Dockerized repository
Configuration
- Configure variables in .env. See .env.example for template.
Reasonable defaults are provided. Simply use them when working localy.
Do the same for others .env* files.
$ ln -s .env.example .env
Usage
- Run with docker-compose
$ docker-compose up -d
Browse database when working localy
Go to http://localhost:7474 and connect with the following parameters:
- Connect URL: bolt://localhost:7687
- Database: leave empty
- Authentication type: Username / Password
- Username: neo4j
- Password: neo3j
Neo4j v3 restore
docker-compose -f docker-compose.yml -f docker-compose.shell.yml run --rm neo4j bash
From dev env:
docker-compose -f docker-compose.yml -f docker-compose.override.yml -f docker-compose.shell.yml run --rm neo4j bash
Backup and restore (Neo4j V4)
see https://neo4j.com/docs/operations-manual/current/backup/
When working localy, docker-compose.override.yml adds a local bind mount to the /backups folder.
Backups can be downloaded from Nexus. They have to be decompressed in the ./backups bind mounted folder.
Create an online backup (command to be executed in the context of the neo4j container, with docker-compose exec neo4j):
neo4j-admin backup --backup-dir /backups --database crunchbase-1.0.0
Restore/create from dataset:
neo4j-admin restore --from /datasets/4.2.0/crunchbase --database crunchbase-1.0.0 --verbose
Restore from backup:
neo4j-admin restore --from /backups/4.2.0/crunchbase --database crunchbase-1.0.0 --verbose
in v3.5.x
neo4j-admin restore --from /backups/3.5.15/fincrime-1.0.0/ --database graph.db
On first creation of a db, you will have to:
:use system
CREATE DATABASE `crunchbase-1.0.0` WAIT;
You can then check that the db has succesfully been restored with:
:use crunchbase-1.0.0
match (n) return n limit 10
offline load
neo4j-admin load --from=/datasets/crunch.3.5.15 --database=crunchbase-1.0.0
and with cypher-shell (the credential are specified in the env) :
CREATE DATABASE crunchbase;
Plugins
Apoc
see https://neo4j.com/labs/apoc/4.2/installation/
Download the appropriate version of apoc plugin and drop it in the plugins folder:
curl -L https://github.com/neo4j-contrib/neo4j-apoc-procedures/releases/download/4.2.0.1/apoc-4.2.0.1-all.jar -o plugins/apoc-4.2.0.1-all.jar
Warning: Check the matching version for your version of Neo4J
Aura

From a shell, stoped database :
bin/neo4j-admin push-to-cloud --bolt-uri neo4j+s://XXXXX.databases.neo4j.io --database=fincrime-1.0.0 --overwrite
