Julia cluster using docker



I have asked this in stackoverflow.com and I was recommended to post it here:

I am trying to connect to docker containers using the default SSHManager. These containers only have a running sshd, with public key authentication, and julia installed.

Here is my dockerfile:

FROM rastasheep/ubuntu-sshd
RUN apt-get update && apt-get install -y julia
RUN mkdir -p /root/.ssh
ADD id_rsa.pub /root/.ssh/authorized_keys

I am running the container using:

sudo docker run -d -p 3333:22 -it --name julia-sshd julia-sshd

And then in the host machine, using the julia repl, I get the following error:

julia> import Base:SSHManager
julia> addprocs(["root@localhost:3333"])
stdin: is not a tty
Worker 2 terminated.
ERROR (unhandled task failure): EOFError: read end of file
Master process (id 1) could not connect within 60.0 seconds.

I have tested that I can connect to the container via ssh without password.

I have also tested that in julia repl I can add a regular machine with julia installed to the cluster and it works fine.

But I cannot get this two things working together. Any help or suggestions will be apreciated.
