Hello @danielsilva. I'm afraid that I can't reproduce this.
I've created a new image based on neo4j/neo4j:2.3.0
that sets the auth environment variable, as you did. It successfully sets the password and exposes the instance from the host.
One possible explanation for the problem you saw is that setting the password takes a little time because we have to start and stop the server: the only way to set the password is through the API. During that initial start/stop we bind to localhost
, so the server is not misleadingly available temporarily.
That suggests that if you were to wait a bit longer (or retry until you get a response), your request might succeed.
But I can't explain the logs that you see. Here is my session where I try to reproduce your problem:

You can see that the server starts, bound to localhost:7474
, stops and then starts again bound to 0.0.0.0:7474
.
from docker-neo4j.
My bug looks slightly different as there are no visible logs and Neo4j won't even start any time I define an overriding environment variable with docker run
.
from docker-neo4j.
@fbiville I have tried this on a Linux box (Ubuntu 15.04) with Docker 1.8.2:

Can you tell me what you see if you do exactly the same thing?
from docker-neo4j.
@fbiville And I've now checked this with Docker 1.9.0 and got the same results.
from docker-neo4j.
Unfortunately, here is what I get:

It seems the issue is bin/neo4j start
is running in foreground and not allowing the rest of the script to be executed (like changing the password and restart the service)
from docker-neo4j.
@bivas I haven't used docker-compose
, but that doesn't look right to me. Why are you providing bin/neo4j start
as a command? The default command is neo4j
, which will start the server; I don't think you'll need to provide a command at all if that's what you are trying to achieve. (Or specify the entrypoint, I think.)
from docker-neo4j.
@fbiville Are you running on Linux or OSX?
from docker-neo4j.
I override the entrypoint so I can add the debug flag. This is a common
practice to debug containers.
The command might be wrong, but even the container is calling 'neo4j' which
triggers the first "if" statement.
This is just a way to show what's wrong with the entrypoint script.

#16 (comment).
from docker-neo4j.
@bivas Thanks for the quick response. The entrypoint override is a good idea.
I've just tried your docker-compose.yml
with command: neo4j
(and the memory config removed because my system didn't have enough for those settings) and it worked fine. Can you try that, please?
from docker-neo4j.
Can you please add the memory settings just with lower values?
I tried it with latest docker and docker-compose versions. Still hangs at
the same line (bin/neo4j start).
from docker-neo4j.
@bivas Yes, I've now tried it with the memory settings and still can't see any problem. Have you tried it with command: neo4j
?
from docker-neo4j.
@benbc i tried it several times - hangs every time; same location
I've tested with tags
neo4j/neo4j:latest
(image ID:edd19eb4421b
)neo4j/neo4j:2.3.0
(image ID:255313be2662
)neo4j:latest
(image ID:f9511d2c10be
)
Which tag are you using? (maybe on your workstation the latest
tag refer to an unpublished artifact)
Docker Engine version 1.9.0
Docker Compose version 1.5.0
from docker-neo4j.
@bivas What platform are you running on?
from docker-neo4j.
@benbc Linux Mint

Hello @benbc,
Unfortunately I was unable to make it work. If I configure NEO4J_AUTH the docker container is bound to localhost:7474, if I don't configure NEO4J_AUTH it's bound to 0.0.0.0:7474
I am also using Linux Mint.
Thanks for helping.
from docker-neo4j.
@benbc sorry for the late reply: when I run on Mac -> no problem, when I run on Linux (Mint) -> I cannot start Neo4j container with auth envvar
from docker-neo4j.
We have identified the problem, and are working on a solution.
For reasons, we currently make use of the lsof
command to ensure that the server is running and accepting connections on a given port so the password can be changed. In the default configuration of Linux Mint with AppArmor installed, docker does not have the access it needs for lsof
to work the way we expect it to. Linux Mint with AppArmor, is currently the only known default configuration that exhibits this behaviour.
We will be providing a more concrete, long term solution for this as soon as possible, but in the meantime, you can work around this issue by running docker with --privileged=true
. Note that this is not considered a permanent solution, but rather as a temporary workaround while we work out the best configuration for using Neo4j in docker with AppArmor.
from docker-neo4j.
Alright, @srbaker thanks for the tip!
from docker-neo4j.
Commit 80db437 updates the documentation for the current best known fix.
from docker-neo4j.
Can you specify the CAP to add instead of running in privileged mode?
from docker-neo4j.
Unfortunately, cap-add does not work. I'm not certain of the exact details, but ptrace is being disabled at a level lower than cap-add enables it. :(
