⁠neo4j-config-cli

neo4j-config-cli is a Neo4j⁠ utility to ensure the desired configuration state of a Neo4j database based on a json file definition.

Docker : https://hub.docker.com/repository/docker/graphaware/neo4j-config-cli⁠

The following docker-compose.yml :

version: '3.7'
services:
  neo4j:
    image: neo4j:4.4.11-enterprise
    ports:
      - "7474:7474"
      - "7687:7687"
    environment:
      - NEO4J_ACCEPT_LICENSE_AGREEMENT=yes
      - NEO4J_AUTH=neo4j/${NEO4J_PASSWORD:-password}
  neo4j-config-cli:
    image: graphaware/neo4j-config-cli:1.2.0
    environment:
      - NEO4J_USER=neo4j
      - NEO4J_PASSWORD=password
      - NEO4J_URI=bolt://neo4j:7687
      - IMPORT_PATH=/config
    volumes:
      - "./config:/config"

with the following json definition in config/simple-db-create.json

{
    "kind": "Database",
    "name": "movies",
    "dropIfExists": true
}

will wait Neo4j is started then drop the movies database and recreate it, once done the neo4j-config-cli container will stop :

⁠Config files

Two kind of config files are supported today :

Database kind
Role kind

⁠Database Config File

Structure

{
  "kind": "Database",
  "name": "movies",
  "dropIfExists": true,
  "skipCreate": false,
  "indexes": {
    "fulltext" : [
      {
        "labels": ["Person"],
        "properties": ["name"],
        "name": "Person"
      }
    ]
  },
  "constraints": {
    "unique": [
      {
        "label": "Movie",
        "property": "title",
        "type": "UNIQUE"
      }
    ]
  },
  "seeds": ["movies.cypher"]
}

⁠Role Config File

Structure

{
  "kind": "Role",
  "name": "ut1",
  "dropIfExists": true,
  "privileges": [
    {
      "graph": "*",
      "access": true,
      "rules": [
        {
          "target": "node",
          "labels": "*",
          "action": "match",
          "resource": "all_properties",
          "access": "GRANTED"
        },
        {
          "target": "node",
          "labels": "Person",
          "action": "read",
          "resource": "born",
          "access": "DENIED"
        }
      ]
    }
  ]
}

⁠Neo4j Aura

The command CREATE DATABASE is not available on Neo4j aura, you thus have to skip the step where this tool will execute that command by specifying skipCreate = true :

{
  "kind": "Database",
  "name": "neo4j",
  "skipCreate": true
}

A full working example with Aura is available here⁠ after inserting your Neo4j Aura credentials in the docker-compose file.

⁠Importing from remote files

You can let your config files on the web, for eg as a Github Gist : https://gist.github.com/ikwattro/f99c1ed085673065fcb4e850526ccd49⁠

You will need to specify the raw versions of it, for eg :

version: '3.7'
services:
  neo4j:
    image: neo4j:4.3.3-enterprise
    ports:
      - "7474:7474"
      - "7687:7687"
    environment:
      - NEO4J_ACCEPT_LICENSE_AGREEMENT=yes
      - NEO4J_AUTH=neo4j/${NEO4J_PASSWORD:-password}
  neo4j-config-cli:
    image: graphaware/neo4j-config-cli:1.2.0
    environment:
      - NEO4J_PASSWORD=password
      - NEO4J_URI=bolt://neo4j:7687
      - IMPORT_PATH=https://gist.githubusercontent.com/ikwattro/f99c1ed085673065fcb4e850526ccd49/raw/35f077b71e3f7a9fd95b0288cf6d622eea3d6501/db-demo.json

⁠Seeding only an existing database

docker run --rm -it \
    -e NEO4J_URI=neo4j+s://18894d85.databases.neo4j.io \
    -e NEO4J_PASSWORD=tT3h3ieK4sw-MATaEaimFFHY9YqkgYNo9WNYcEBqMZ4 \
    -e seed-only=true \
    -e seed-url=https://bit.ly/2XnJzFn \
    graphaware/neo4j-config-cli:1.3.0
