How to ssh into docker-machine VirtualBox instance?

Question

docker-machine version 0.2.0 docker version 1.6.2

I\'m using docker-machine to create a machine using VirtualBox. Everything works fine but I\'d like to ssh into th

Answer 1

If for some reason you'd rather use the ssh command rather than docker-machine ssh, you can do

ssh `docker-machine ip machine_name` -ldocker -i ~/.docker/machine/machines/machine_name/id_rsa

Answer 2

For mac OX,the machine and its keys are located here (make sure you have the keys in there, something like the below:

~/project/dev/docker_notes za$ ls /Users/za/.docker/machine/machines/default/
.DS_Store        ca.pem           config.json      disk.vmdk        id_rsa.pub       server-key.pem
boot2docker.iso  cert.pem         default/         id_rsa           key.pem          server.pem

1) list available vms.

> ~/project/dev/docker_notes za$ docker-machine ls

>     default   -        virtualbox   Running   tcp://192.168.99.100:2376           v1.11.0

In my case, the name of the machine is default. So, just

~/project/dev/docker_notes za$ docker-machine ssh default

As you can see, I am able to ssh into docker-machine/instance.

docker@default:~$ uname -a

Answer 3

Finally, I found an answer :

I'm on Windows with Docker Toolbox (Docker Machine).

If I docker-machine -D ssh default, I find that the SSH parameters should be :

Host : localhost
Port : 51701
User : docker
Key : .docker\machine\machines\default\id_rsa

When I change my Putty/MobaXterm settings to match, voila, I can SSH into the container.

Answer 4

You can log into docker-machine hosts by just running

docker-machine ssh default

(Using the "default" host here)

The identity files should be stored under ~/.docker/machine/machines. If you want to log into a container (as opposed to the host), use docker exec as suggested by user2915097.

Answer 5

We can also ssh into the docker via following command -

docker exec -it /bin/sh

Answer 6

if you really need to do it via ssh, this is working with docker 1.8.2

init docker:

eval "$(docker-machine env default)"

get the IP from your default docker machine:

docker-machine ip default

this prints something like this out: 192.168.99.100

ssh docker@192.168.99.100

password is tcuser but you can also use the identity file, see other answer
