Question 1

How do I set up persistent storage for Neo4j in Docker?

Accepted Answer

Use Docker volume mounts for the /data and /logs directories. In the run command, add flags like --volume=$HOME/neo4j/data:/data to store data outside the container, as shown in the README examples for data persistence.

Question 2

Does the Neo4j Docker image support clustering?

Accepted Answer

Yes, but it requires additional configuration and orchestration. You'll need to set up multiple containers with specific environment variables and networking; refer to Neo4j's official documentation for detailed clustering setup in Docker.

Question 3

How can I change Neo4j configuration settings in Docker?

Accepted Answer

Configuration can be adjusted using environment variables or by mounting custom configuration files. For example, set env vars like NEO4J_dbms_memory_pagecache_size in the Docker run command, as per Neo4j's external docs for containerized deployments.

Question 4

Neo4j Docker vs native installation: which is better for development?

Accepted Answer

Docker is ideal for consistent, isolated environments and quick setup, while native installation offers more control over system resources. For development, Docker simplifies dependency management, but native might be preferred for performance testing.

Question 5

What ports does the Neo4j Docker container use by default?

Accepted Answer

It exposes port 7474 for the HTTP interface (browser UI) and port 7687 for the Bolt protocol (database connections). These are mapped in the example Docker run commands with --publish flags.

Question 6

How do I run Neo4j Enterprise Edition in Docker?

Accepted Answer

Use the neo4j:enterprise image and set the environment variable NEO4J_ACCEPT_LICENSE_AGREEMENT=yes. For instance, run docker run --env=NEO4J_ACCEPT_LICENSE_AGREEMENT=yes neo4j:enterprise, as specified in the README.
