Domino Environments, or Compute Environments, help teams manage their projects better. They improve processes in MLOps, generative AI, and data science workflows.
In Domino, environments are defined by Docker images that create isolated containers for each execution unit including Workspaces, Runs, Apps, and Models. This setup allows professionals to experiment and customize their work in a contained, versioned, and shareable space, boosting reproducibility and collaboration.
You can create new environments, use those provided by Domino, or modify existing ones. You might choose to create or alter an environment if:
-
You must install a package for Python, R, Octave, or some other software dependency.
-
You want to cache a package or library so that it’s immediately available when you start a run.
-
You manage an organization and want to create a default Environment for all projects.
Domino has two main types of Compute Environments: the Domino Standard Environment (DSE) and the Domino Minimal Environment (DME). The DSE offers a complete set of libraries and packages, while the DME is lighter and includes fewer packages.
Domino also provides Cluster Environments, which work like DSEs but are designed for specific types of clusters. The environments are smaller and simpler, suitable only for worker nodes in a cluster, while DSEs cannot be used for worker nodes.
You can view the environments you can access by clicking Govern > Environments in the navigation bar.
In the Environments Overview page, you can see a list of:
-
Global Environments.
-
Specific environments used by Projects you collaborate on.
-
Environments shared with organizations you belong to.
Click an environment’s name to see its details.
| Field | Description |
|---|---|
Overview | The Overview tab lists all metadata about your environment or image. If your environment is built on top of another, you may need to click through to the parent environment before seeing the underlying Docker image. Click Edit Definition if you need to make changes to your environment. |
Revisions | All revisions of your compute environment are listed here, along with the build status, timestamp, and Docker image URI. With each saved change, an environment’s revision number increments by one. Domino rebuilds each revision and then pushes it to the local Docker registry. The latest successfully built revision becomes Active by default. |
Revision details | Click the three vertical dots for additional options like viewing build logs, downloading an image source project, or canceling builds. |
Projects | These are listed after being assigned to an environment. You can view details of the project by clicking its name. |
Endpoints | Shows you a list of endpoints for that environment, including the status of the endpoint. |
