How to make data that has been added to the database persistent?

  • 772

I want my data to be persistent in the Docker container in which I am building a neo4j database. However, the commands I've found don't seem to apply to my situation. In fact, it seems that we should do:

docker run -p 7474:7474 -p 7687:7687 neo4j --volume=$HOME/neo4j/data:/data

But in my case there is no neo4 in $HOME:

bash-5.1$ cd $HOME/
.bash_history    .config/         Documents/       .gitkraken/      .gphoto/         .lesshst         Music/           Public/          Templates/       .wget-hsts       
.cache/          Desktop/         Downloads/       .gnome/          .ipython/        .local/          Pictures/        .ssh/            Videos/          
.cert/           .docker/         .gitconfig       .gnupg/          .jupyter/        .mozilla/        .pki/            Téléchargements/ .vscode/

So I already have a neo4j image and it works great:

bash-5.1$ docker run -p 7474:7474 -p 7687:7687 neo4j

    If you run this command, you should get an error on the screen:

    bash-5.1$ docker run -p 7474:7474 -p 7687:7687 neo4j --volume=$HOME/neo4j/data:/data
error: exec: "--volume=/home/msalinas/neo4j/data:/data": stat --volume=/home/msalinas/neo4j/data:/data: no such file or directory

    This happens because the options docker runyou have to pass in before the image name ( command documentation ):

    docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]

    If you launch it putting the name of the image at the end it will work without problems:

    docker run -p 7474:7474 -p 7687:7687 --volume=$HOME/neo4j/data:/data neo4j
