Profiles: Manage Stack Configurations

How to manage stack configurations with profiles
This is an older version of the ZenML documentation. To read and view the latest version please visit this up-to-date URL.
ZenML implicitly stores all the information about the configured Stacks, Stack Components, and Stack Component Flavors in the Global Configuration on the filesystem of the machine where it is installed. The details of how ZenML stores this persistent data, where it is located, and how it is accessed can be configured via the ZenML Profile.

The default Profile

The first time you run any zenml CLI command on a machine, a default Profile is automatically created and set as active. Unless otherwise configured, this default profile will contain all stacks and stack components that you create on your machine.
$ zenml profile list
Creating default profile...
Initializing profile `default`...
Initializing store...
Registered stack component with type 'orchestrator' and name 'default'.
Registered stack component with type 'metadata_store' and name 'default'.
Registered stack component with type 'artifact_store' and name 'default'.
Registered stack with name 'default'.
Created and activated default profile.
Running without an active repository root.
Running with active profile: 'default' (global)

Creating and Changing Profiles

Multiple Profiles can be created on the same machine to simulate the experience of using several independent ZenML instances completely isolated from each other. The same or even different users can then manage their projects in the context of different Profiles on the same machine without having to worry about overwriting existing configurations.
To create a new profile, run
zenml profile create <NEW_PROFILE_NAME>
To set an existing profile as active, run
zenml profile set <PROFILE_NAME>
The active Profile determines the stacks and stack components that are available for use by ZenML pipelines. New stacks and stack components registered via the CLI are only added to the active profile and are available only as long as that profile is active.
If you want to reuse stacks from other profiles, you can use the zenml stack copy CLI command to copy stacks between profiles. For more information, run zenml stack copy --help or visit our CLI docs.

Detailed Example

Detailed usage example of multiple profiles
The following example creates a new profile named zenml, sets it as active, and then shows how the default profile is unaffected by the operations performed while the zenml profile is active:
$ zenml profile create zenml
Running without an active repository root.
Running with active profile: 'default' (global)
Initializing profile `zenml`...
Initializing store...
Registered stack component with type 'orchestrator' and name 'default'.
Registered stack component with type 'metadata_store' and name 'default'.
Registered stack component with type 'artifact_store' and name 'default'.
Registered stack with name 'default'.
Profile 'zenml' successfully created.
$ zenml profile list
Running without an active repository root.
Running with active profile: 'default' (global)

From the above example, you may have also noticed that the Active Profile and the Active Stack are global settings that affect all other user sessions open on the same machine. It is however possible to set the active profile and active stack individually for each user session or project. Keep reading to learn more.
