danhixon/sshd repository overview

⁠docker-sshd

A container from Ubuntu 12.04 with supervisord and openssh-server preinstalled to be used as a base image for other services. A mash up of sullof/docker-sshd⁠ and zumbrunnen/docker-base⁠. This one includes .conf files added to the /etc/supervisor/conf.d directory. This seems neater than appending to the supervisord.conf file.

⁠Usage

$ docker pull danhixon/docker-sshd
  # grant access to my public key
$ docker run -d -e AUTHORIZED_KEYS="$(cat ~/.ssh/id_rsa.pub)" danhixon/docker-sshd
  # grant access to all the public keys in the authorized_keys file:
$ docker run -d -p 372999:22 -e AUTHORIZED_KEYS="$(cat ~/.ssh/authorized_keys)" danhixon/docker-sshd

Include whatever public keys you want to allow ssh access. The above command will copy the authorized_keys of the host to the docker container. Be sure to map a port for it if you want to access it from outside the docker host.

Here's how you connect:

$ docker ps
CONTAINER ID        IMAGE                         COMMAND             CREATED              STATUS              PORTS                   NAMES
e13e48deeb4a        danhixon/docker-sshd:latest   /bin/bash           About a minute ago   Up About a minute   0.0.0.0:372999->22/tcp   grave_lovelace   
$ ssh root@localhost -p 372999
root@0a3739387477:~# echo "Hooray. I made it."

If you are running docker on OSX you must remember that the mapped port is only mapped on the boot2docker instance and will not be accessible from OSX.

⁠What next?

You can create new images starting your Dockerfile with something like

FROM danhixon/docker-sshd

and add any *.conf files you wish to the /etc/supervisor/conf.d/ directory. For example:

ADD supervisor.conf /etc/supervisor/conf.d/rails.conf
