I've rolled my own Dockerfile to start with neo4j and include supervisord to run the docker-entrypoint script. I used a Job and created a modified image from the Neo4j image. The final command exits Cypher shell using :exit and returns to our bash prompt. We can add the following environment variables to our command above to set the advertised addresses: When we run this command, it will create and start the container. The tricky part is to stop the Neo4J database without stopping the container. Finally, the last line of the command above references the Docker image we want to pull from DockerHub (neo4j), as well as any specified version (in this case, just the latest edition). I can successfully perform this but for the dockerized neo4j to recognize it, I need to restart the docker. Then neo4j.getMappedPort() returns this random port.. Once the bolt uri is constructed, the test creates an instance of Neo4j Java driver as usual. Here is where Docker and docker-compose comes to save the day. To change any configurations, we can use the --env parameter in our docker run command to set different values for the settings we want to change. at org.neo4j.io.pagecache.impl.SingleFilePageSwapper.acquireLock(SingleFilePageSwapper.java:227) Load scripts for importing that data can also be placed in this folder for us to execute.
