Random exits about docker-neo4j

[benbc]

@coeus01 Do you see anything in the logs for the failed container? Most likely problem is running out of memory, I would have thought. You may need to set an increased size for heap or cache size -- the environment variable you need depends on which version of Neo4j you're using.

[coeus01]

@benbc Nothing in the logs, this problem also happens sometimes on docker-compose up where

db_1   | Neo4j failed to start

other times it exits earlier:

db_1   | 2016-05-16 08:43:04.206+0000 INFO  Starting...

db_1   | Neo4j failed to start

after a few docker-compose up it works

[benbc]

@coeus01 Do you have any insight into why there are those repeated logs "Starting/Bolt enabled"? Are you trying to start it multiple times there, or is Docker Compose doing that?

[coeus01]

@benbc no.. they are completely random, sometimes it's only one, other times they are 10

[benbc]

@coeus01 Can you give us as much information as possible about your system? Docker and Neo4j versions, OS and version, system memory available, anything else that might be relevant.

[coeus01]

@benbc

• neo4j 3.0.0
• Docker version 1.11.1, build
• docker-compose version 1.7.1, build 6c29830
• Debian GNU/Linux 8.4 (jessie)
• Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
• MemTotal: 4060764 kB

[coeus01]

UPDATE even when I start all the containers with docker start <1> <2> <3> instead of docker-compose up again the neo4j container takes a few shots to start and stay up

[benbc]

@coeus01 Thank you, that's useful information. We'll take a look.

[spacecowboy]

@coeus01 the problem is in your docker-compose.yml file

this line:

NEO4J_AUTH: "neo4j/neo4j"   

change the password to anything other than neo4j.

NEO4J_AUTH: "neo4j/foo"   

Neo4j does not support setting a custom password equal to the default neo4j password. That's why the container never comes up. An error message is shown if you try to do it in the browser.

We should probably add some logic to the docker entrypoint script that clearly tells you not to set the password to neo4j

[coeus01]

@spacecowboy my password is not neo4j, it was for the sake of an example. Also as I said before after a few times it works ok, so even if I had the password neo4j it wouldn't matter if I could get it working after a few tries.

[benbc]

@coeus01 We have now reproduced your problem. Setting the password via NEO4J_AUTH doesn't work on Debian Jessie (although it works fine on various Ubuntu versions). We are investigating further.

[benbc]

@coeus01 The fix for this will be in Neo4j 3.0.2.

[textbook]

@benbc when will this version be available in the Docker Hub? Currently it's still showing 3.0.1, so I think the issue should still show as open.

[benbc]

@textbook The 3.0.2 image will be published later today.

[textbook]

For anyone else wondering, the new image will be available when this PR is accepted: docker-library/official-images#1809
