Too many open files with `codenvy/che:nightly` #143

freewind · 2015-12-29T06:19:50Z

I have the same problem with this issue #140.

I run the image codenvy/che:nightly in a virtual box, which is running ubuntu 14.04, and the "open files" settings is increased as following:

scaleworks@ubuntu:~$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 31375
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 100000
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 200000
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

and append the following to /etc/security/limits.conf:

*                hard    nofile          100000
*                hard    nproc           200000
*                soft    nofile          100000
*                soft    nproc           200000

Then I start codenvy/che:nightly:

$ docker run -it -p 8080:8080 codenvy/che:nightly

It seems started correctly:

$ docker run -it -p 8080:8080 codenvy/che:nightly

@wu560130911 Not understand why you quote this warning? It should not related to the "too many open files" issue

TylerJewell · 2015-12-29T14:27:59Z

I periodically run into this issue, but have been unable to cause it to happen reliably. In doing research on it, there are some additional fixes. On the host system:

update the /etc/security/limits.conf to include :* - nofile 64000
add to your /etc/sysctl.conf : fs.file-max = 64000
restart sysctl : sudo sysctl -p
restart the docker daemon

Also, though I believe it is unrelated, you will need to start Che with --privileged mode.

I am going to spend some time this afternoon attempting to reliably recreate the too many open files circumstances so that we can put some tests around it and also explore different solutions.

freewind · 2015-12-29T21:02:06Z

@TylerJewell Thanks very much, I will try it tomorrow ~

TylerJewell · 2015-12-29T21:11:57Z

Sure thing. It should be noted that running Che inside of a Docker
container is provided for experimentation. When running Che in production,
we only run the server natively. Docker is awesome for quick start, but it
does pose interesting issues:

All state is inside the container, so you need to snapshot to retain
state. Initial snapshots take forever.
You need to mount your projects outside the container, so that is more
configuration.
Lots of port mapping to be managed
And since Che launches docker itself, you need --privileged mode.

But we wnat to make this work, so I also think it's a great test case &
exercise.

You do not run the image in the right way. --privileged flag is Mandatory for Docker to start inside a Docker container.

Please, check docs - https://eclipse-che.readme.io/v4.0/docs/install-using-docker

freewind · 2015-12-31T02:56:23Z

@eivantsov Yes, you right right!! Sorry for my stupid mistake. But the error is too misleading 😭

TylerJewell · 2015-12-31T03:02:27Z

We have been working on a new set of che startup scripts that will start
Che either in native mode or as a Docker image.

This will prevent these sorts of startup mistakes from happening.

If you want to test it, you can check out branch IDEX-3975. The che.bat
and che.sh scripts should have self-explanatory help at that point.

These scripts also take care to start virtualbox, docker-machine, and
docker if it's not started, too along with all environmental setup.

@TylerJewell Thanks, that's great! I will try it later, these scripts are really helpful for docker newbies

freewind · 2015-12-31T16:02:48Z

@eivantsov Sometimes the "too many open files" error still appear even if I set --privileged

ghost · 2016-01-01T10:06:43Z

Sometimes? Under what conditions?

freewind · 2016-01-01T15:42:07Z

@eivantsov It didn't happen today. "Sometimes" means I didn't change anything, only restart the container with the same command, it reported that error, but I can't remember the details.

I will reopen this next time I see it

freewind · 2016-01-01T16:52:01Z

It is suddenly report "too many open files". I didn't do anything special, just kill previous container and run it again (it was OK last time).

The command is:

docker run -it --privileged -e DOCKER_MACHINE_HOST=159.203.222.119 -p 8080:8080 -p 32768-32788:32768-32788 codenvy/che:nightly

The log is:

I can't see if is the memory run up, because no matter I input any command, it show the same error:

twer@ubuntu-4gb-sfo1-01:~$ top
-bash: start_pipeline: pgrp pipe: Too many open files in system
-bash: /usr/bin/top: Too many open files in system

ghost · 2016-01-01T18:13:06Z

I just tried it on freshly created machines on Digital Ocean and Azure, and failed to reproduce it.

-bash: start_pipeline: pgrp pipe: Too many open files in system - is this on your host or in a container?

Can you exec into a container after it has been started and run docker info there?

freewind · 2016-01-02T03:59:56Z

It's from the log of the docker container which runs the che.

Can you exec into a container after it has been started and run docker info there?

Sorry, when I see that errors, I can't do anything on the host. Even a simple ls command will fail and also reports "too many open files" error, so I can't exec into the container.

I have to kill the container by press "ctrl + c", and then I can execute other linux commands

Maybe I can record it next time and share to you

ghost · 2016-01-02T07:50:00Z

It is a host problem then. I have tried to reproduce it on different environments - no luck. It is possible that when a container starts it consumes hosts resources that may be insufficient.

freewind · 2016-01-05T05:44:30Z

Just now, it happens one time again. But if I ctrl+c to cancel it and run it again, it works well:

Seems it happens quite randomly.

It has never happened in my mac + virtual box, but happened in digital-ocean and another could host managed by our company.

Just checked it with Digital Ocean - Che started just fine. The issue is with starting Docker in Docker - it looks like this does not work well in all environments.

ghost · 2016-01-25T16:51:29Z

@freewind can you still repeatedly reproduce this issue? Only with Digital Ocean or locally as well?

TylerJewell · 2016-02-05T00:30:02Z

@freewind See the pull request #257 as a way that will help eliminate this issue.

ghost · 2016-02-21T07:05:04Z

@freewind I think after switching to a a no-docker-in-docker image the problem fixed itself.

Closing the issue since we do not start Docker in Docker anymore.
