What is Neo4j?

• Neo4j is an open-source, NoSQL, native graph database that provides an ACID-compliant transactional backend for your applications. Initial development began in 2003, but it has been publicly available since 2007. The source code, written in Java and Scala, is available for free on GitHub or as a user-friendly desktop application download. Neo4j has both a Community Edition and Enterprise Edition of the database. The Enterprise Edition includes all that Community Edition has to offer, plus extra enterprise requirements such as backups, clustering, and failover abilities.
• Official Docker image: https://hub.docker.com/_/neo4j/
• GitHub repository: https://github.com/neo4j/docker-neo4j-publish

What is APOC?

• APOC stands for Awesome Procedures on Cypher. Before APOC’s release, developers needed to write their own procedures and functions for common functionality that Cypher or the Neo4j database had not yet implemented for support. Each developer might write his own version of these functions, causing a lot of duplication.

What is GDS?

This library provides efficiently implemented, parallel versions of common graph algorithms for Neo4j, exposed as Cypher procedures.

How to run

The docker definition has two required volumes - one in which Neo4j stores its data and another, from which APOC can import external file (e.g. GraphML) into Neo4j. Both must be specified when starting up the container.

1. Neo4j Data - map to /data of the container
2. APOC Imports - map to /imports of the container

Example:

$ mkdir -p neo4j/data
$ mkdir -p neo4j/imports
$ echo password > neo4j/password

Then start the docker:

$ docker run -d \
  --user=$(id -u):$(id -g) \
  --name=neo4j \
  --publish=7473:7473 \
  --publish=7474:7474 \
  --publish=7687:7687 \
  --volume=$(pwd)/neo4j/data:/data \
  --volume=$(pwd)/neo4j/imports:/imports \
  -e NEO4J_AUTH=neo4j/password \
  fabrictestbed/neo4j:latest

Once the container completes it's startup script a web UI will be running at http://localhost:7474/

Verify that container has completed script

$ docker logs neo4j
