Containers are pulled (e.g., downloaded) from containers registries. The most famous one is probably the DockerHub.

Setup a private registry#

You can setup any Docker-compatible registry on csquare using the registry credentials.


Registries are user-based, which means that all the collaborators that run experiments that require access to your private registry need to set up the credentials accordingly.


  1. Login to your csquare account.
  2. Go to the settings page.
  3. Scroll down to "Manage your registries" section.
  4. Fill your host, user and password.
  5. Hit the Save button.


DockerHub is the default Docker registry; this is a general-purpose registry where you can find variety of container images from node to php and also minimal distribution images such as ubuntu:20.04.


Even if you are only using public images from the DockerHub, we highly recommend you to setup your DockerHub credentials on csquare to avoid being rate-limited. See DockerHub announcement on rate limit for more information.


  1. Login/register to the DockerHub.
  2. Go the Account Security page.
  3. Create a New Access Token and store it carefully.
  4. Setup your registry using the following values.


The NVIDIA NGC is the home of the official NVIDIA containers. You will find the latest and best images to run your GPU-based experiments. You can learn more about the NGC on the introduction page.

You can also browse the available containers on the dedicated container page.

Since the NGC is not public - which means that you have to provide an API key to csquare - you first need to register on the NGC.

  1. Sign up here: and confirm your email, accept the terms, etc.
  2. Create an API key - copy the key and store it carefully.
  3. Setup the TWO following registries on csquare:

As mentioned in the NGC instruction page, the user is literally $oauthtoken.
