Unable to persist state during docker build #250

Open sdaschner opened 4 years ago

sdaschner commented 4 years ago

I expected that I can modify the initial state of database in the Dockerfile, e.g. creating some indexes. It seems, however, that the state that I persist during the build steps is lost, maybe due to the entrypoint script?

Steps to reproduce

Following Dockerfile:

FROM neo4j:4.0.4-enterprise
ENV NEO4J_ACCEPT_LICENSE_AGREEMENT yes

COPY neo4j.conf /conf/
COPY schema.cypher /

RUN neo4j-admin set-initial-password test \
 && neo4j start \
 && sleep 10 \
 && /bin/bash -c "cat /schema.cypher | cypher-shell -u neo4j -p test --format verbose" \
 && neo4j stop

Following schema.cypher:

:begin
CREATE CONSTRAINT ON (node:SomeNode) ASSERT (w.uuid) IS NODE KEY;
:commit

CALL db.awaitIndexes(300);

The resulting database image, after a docker build -t <image> . however is empty, without any indexes. If I run the RUN steps manually in a Docker container, it works as expected.

Tested with both neo4j:4.0.4-enterprise and neo4j:3.5.14-enterprise.

What's the log output of the docker build? Neo4j needs to be started as the neo4j:neo4j user, but your Dockerfile will be running it as root, which might be causing problems.

Could you also try adding USER neo4j:neo4j before your RUN?

Adding the USER directive didn't change anything. The contents of all the directories and logs are empty on start of the image (here e33d33c85441)...
