带有初始数据的 Neo4j 容器 (docker) [英] A Neo4j container (docker) with initial data in it

问题描述

我使用过的其他数据库 docker(如 Postgres)有一种机制，可以在容器第一次启动时将一些初始数据导入到它们的空实例中.这通常是将 SQL 文件放在特定文件夹中的形式.

Other database dockers that I've worked with (like Postgres) have a mechanism to import some initial data into their empty instance once the container starts for the first time. This is usually in form of putting your SQL files in a specific folder.

我需要为 Neo4j 做同样的事情.我想用一些数据组合一个 Neo4j docker 图像.这样做的正确方法是什么?

I need to do the same for Neo4j. I want to compose a Neo4j docker image with some data in it. What's the right way to do this?

推荐答案

这可以实现...有两个要求:

This could be achieved... There are 2 requirements:

1. 设置初始密码，可以使用 bin/neo4j-admin set-initial-password 然后
2. 从文件中以密码格式导入数据cat import/data.cypher |NEO4J_USERNAME=neo4j NEO4J_PASSWORD=${NEO4J_PASSWD} bin/cypher-shell --fail-fast

示例 Dockerfile 可能看起来像这样

Sample Dockerfile may look like this

FROM neo4j:3.2

ENV NEO4J_PASSWD neo4jadmin
ENV NEO4J_AUTH neo4j/${NEO4J_PASSWD}

COPY data.cypher /var/lib/neo4j/import/

VOLUME /data

CMD bin/neo4j-admin set-initial-password ${NEO4J_PASSWD} || true && 
    bin/neo4j start && sleep 5 && 
    for f in import/*; do 
      [ -f "$f" ] || continue; 
      cat "$f" | NEO4J_USERNAME=neo4j NEO4J_PASSWORD=${NEO4J_PASSWD} bin/cypher-shell --fail-fast && rm "$f"; 
    done && 
    tail -f logs/neo4j.log

构建镜像 sudo docker build -t neo4j-3.1:loaddata .

并运行容器 docker run -it --rm --name neo4jtest neo4j-3.1:loaddata
