Creating workspace with che running inside a docker container fails with certificates https error

[lbriais]

As Che requires some dependencies (mainly java and docker), and that I have a server which does nothing else than running docker containers (it is basically a Ubuntu server 14.04 with nothing but docker installed on it), I didn't want to run Che on bare metal, but in fact having it part of my docker infrastructure.

I have already containers that require access to the docker host, and this is not a problem. What I do for that is that I mount as a volume inside the container the /var/run/docker.sock file from the host, install docker in the container, create a user in the container in the 'docker' group.

That works great, and indeed, inside the container this user is able to communicate with the docker daemon (ps, stop/start containers).

I have been able to install and start eclipse-che in this container. No problem so far.

Now when I try to create a workspace in my browser, I get a strange error about https:

Any hint about what I should do to fix this ?

Forgot to mention the workspace remains in 'Starting' state with no possibility to stop or delete it...

What happens when you run this:

docker run -ti -v /var/run/docker.sock:/var/run/docker.sock -v /home/user/che/lib:/home/user/che/lib-copy -v /home/user/che/workspaces:/home/user/che/workspaces -v /home/user/che/tomcat/temp/local-storage:/home/user/che/tomcat/temp/local-storage -e "DOCKER_MACHINE_HOST=yourVMmP" --net=host codenvy/che:no_dnd

We have got a pull request that will simplify running Che in Docker with docker.sock mounting - #257

@lbriais take a look at https://eclipse-che.readme.io/docs/usage-docker

Can you try our image?

@lbriais it's been a while since you first reported this issue.

Can you confirm you still face it with the latest nightly build?

I am closing the issue. Feel free to reopen if the problem is still there.
