How can I access my instances with SSH?

In order to access your instances with SSH, you first have to tell Scalarium to provide every instance with a SSH key.

You can either define a default SSH key on the cluster or specify on when you add an instance.

This SSH key will be distributed to the instance and put in /home/ubuntu/.ssh/authorized_key, so the ubuntu user can login using this key. Password based authentication is disabled by default.

If you created the key using Scalarium, you can also SSH into the instance using a Java applet on the instance view.

If you want to use your native command line, just download the SSH key on from it's asset page.

Once downloaded, put it in your ssh directory, e.g. ~/.ssh/id_scalarium_key and make sure the permissions are 0600. Then login using this key and the ubuntu user:

$ ssh -i ~/.ssh/id_scalarium_key ubuntu@INSTANCE-DNS

If you need root access, just sudo to root:

sudo su -
