Gain Shell Access To Your Domino Instances

by on November 9, 2016

Domino offers a managed, scalable compute environment that provides push-button convenience to data scientists, whether they’re interested in exploring data in a Python notebook, or training a model using an R script. While Domino offers many opportunities for teams to customize and share environments, some problems are best solved with shell access. With Domino’s latest release, users can do just that.

Once an interactive session has been launched, you will be able to gain access to the running instance using SSH by following the instructions in the Run details. Check out this short video:

Using SSH

Once you have configured your SSH keys, you can copy this command right into your favorite terminal program, and you will immediately have access to the SSH session running your notebook. Note that this will only work on the machine which has the key you uploaded. If you wish to access Domino from multiple machines, you must upload all of their respective keys.

Configuring SSH

Configuring your account for ssh access is easy with Domino. Navigate to your Account Settings, accessible by clicking on your user name in the top right corner of a Domino application page:

From the Account Settings page, navigate to new SSH Keys configuration section of your account information page.

Adding a new key is easy. Simply find your public key on your own machine. Often this is ~/.ssh/id_dsa.pub or ~/.ssh/id_rsa.pub and copy the contents of this file into the dialog. For example, this is what one of these keys may look like:

$ cat ~/.ssh/id_rsa.pub
ssh-rsa AAAB3nZaC1aycAAEU+/ZdulUJoeuchOUU02/j18L7fo+ltQ0f322+Au/9yy9oaABBRCrHN/yo88BC0AB3nZaC1aycAAEU+/ZdulUJoeuchOUU02/j18L7fo+ltQ0f322AB3nZaC1aycAAEU+/ZdulUJoeuchOUU02/j18L7fo+ltQ0f322AB3nZaC1aycAAEU+/ZdulUJoeuchOUU02/j18L7fo+ltQ0f322AB3nZaC1aycAAEU+/ZdulUJoeuchOUU02/j18L7fo+ltQ0f322klCi0/aEBBc02N+JJP john@example.com

Take that text, copy it into the text box, and remember to give your SSH key a memorable name. You want to be able to remember which keys were on which computers in case you ever need to revoke access. The process should look like this gif.

From the Account Settings screen, you will be able to manage your keys if you ever need to delete one. Now your account is enabled and provisioned with SSH.
