Start che with --volumes-from using /data in data container

I am trying to get Eclipse Che with docker working using a data container for /data instead of using a local bind mounted volume.

Using local volumes goes against our standard for dockerized setups, as we want to be as independent of the host file systems as possible.

Reproduction Steps:

So I was trying a simple setup like this: First, create a “che-data” container:

docker create --name che-data -v /data busybox

Try to start che using this data container:

docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock --volumes-from che-data eclipse/che start

Che version: 5.1.2

OS and version:
RancherOS 0.7.1

Docker version: 1.12.3

Che cli.log output:

INFO:                          eclipse/che start

This would be similar to creating a fdata container in docker-compose and using this - which I have not tried yet, but I assume this will give the same error.

Question is - does che not support using data containers for data storage?

@riuvshin @vkuznyetsov - FYI, this is the original early issue that triggered the thoughts.

1. Make /data optional
2. Use our property overrides on command line for configuring che.env
3. Allow for volumes-from setting of volumes
4. A process for how to save workspaces to disk as a result

I’m trying to deploy Eclipse Che (6.5.0) on Docker EE 2.0 and I’m in trouble to assign a /data folder to a “local” volume (I’m executing only docker client on my pc configured by Docker EE client env.cmd).

This issue is close, but it seems nothing change… it means Eclipse Che doesn’t support volume containers?

docker volume create eclipseche_volume
docker run  -it --rm  -e CHE_MULTIUSER=true -e CHE_HOST=dockeree.xxxx.com -v /var/run/docker.sock:/var/run/docker.sock -v eclipseche_volume:/data eclipse/che:6.5.0 start
