Authentication and authorization for Cognite Toolkit

How you set up authentication and authorization for Cognite Toolkit depends on whether you'll use it in a CI/CD pipeline with full access to the resources in the CDF project or a local development environment with limited access. In both cases, you can use the Auth commands to set up and verify authentication and authorization for the Cognite Toolkit according to your needs.

Set up full access to CDF resources

To set up the Cognite Toolkit with full access to the resources in a CDF project, you typically create a dedicated service account and add it as the sole member of a CDF group with all the required capabilities.

If you're running the Cognite Toolkit as part of a CI/CD pipeline, create a service account for each CDF project you are running. For production projects, the service account should be the only entity that can write configuration settings to the CDF project.

Run the cdf auth init command to set up authentication for the service account. The command automatically calls the cdf auth verify command to guide you through authorization and setting up the necessary group with the required capabilities. See the auth init command for more information.

Quick setup guide

Follow the steps below to set up the Cognite Toolkit with full access to your CDF project using Microsoft Entra ID as the identity provider. The steps to use Amazon Cognito as the identity provider are similar.

1. Create a group in your identity provider and name it, for example, <Name of your CDF project> Toolkit. Store the Object Id of the group securely.

2. Register a new application in your identity provider and name it, for example, <Name of your CDF project> Toolkit service account. Store the Application (client) ID and the Directory (tenant) ID securely.

3. Add the service principal to the group. Store the client secret securely.

4. Sign in to your CDF project. Create a new group and name it cognite_toolkit_service_principal. Give it the Project and Group capabilities. Set the sourceId to the Object Id of the group you created in step 1.

   

5. Run cdf auth init and select client_credentials as the sign-in flow.

   1. Enter the Application (client) ID, client secret, Directory (tenant) ID, and cluster and project name for your CDF project.
   2. Select yes to store the credentials in a .env file so you can reuse the credentials to authenticate for all Toolkit commands.
   3. The command automatically calls cdf auth verify to guide you through setting up the cognite_toolkit_service_principal group with the required capabilities.

6. If you decided to create the .env file manually, or you want to check that you have the necessary capabilities set up correctly, you can run cdf auth verify.

Set up with limited access to CDF resources

You can use the Cognite Toolkit for local development with limited access to CDF project(s), but you will not be able to deploy or clean resources that you don't have access to.

To check the authorization of your credentials, run the cdf auth init --no-verify command. This helps you set up the necessary credentials for authentication, but will not create the necessary group with the required capabilities. See the auth init command for more information.

Auth commands

This section assumes that you've already registered the CDF API and core application in your identity provider, for example, Microsoft Entra ID or Amazon Cognito.

auth init

Cognite Toolkit commands look for a .env file in the current directory and load the environment variables from that file. The auth init command guides you through creating the .env file. You can also create the file manually, for example, from the .env.tmpl file you get when running the cdf repo init command.

Running cdf auth init prompts you to select the sign-in flow, specify the credentials for the flow, and store the credentials in a .env file. Unless your using the --no-verify flag, the command next calls cdf auth verify to guide you through setting up a group with the necessary capabilities. See auth verify for more information.

Choosing the correct sign-in flow

The sign-in flow you choose depends on how you plan to use the Cognite Toolkit.

• The client_credentials flow is recommended for CI/CD pipelines.

• The device_code flow is recommended for local development.

• The token flow is used when you have an OAuth2 token that you want to use, for example if you've created a token with Postman.

• The interactive flow is similar to the device_code flow and is supported as a legacy feature. It opens a browser window for you to sign in.

Each sign-in flow requires different environment variables. See the sign-in flow environment variables stion for more information.

auth verify

Use this command to create the cognite_toolkit_service_principal toolkit group in CDF with the required capabilities to use it without any restrictions. The name of the group is fixed and can't be changed.

This illustration shows the target setup (with Microsoft Entra ID as the identity provider):

To run this command, you must be authenticated and have these CDF capabilities:

• projects:list and projects:read
• groups:list, groups:read, groups:create, groups:update, and groups:delete

If you haven't authenticated with a service account that is a member of a group named cognite_toolkit_service_principal, the command creates (or updates) the cognite_toolkit_service_principal group, and prompts you to switch to the service account that is a member of this group.

Troubleshooting .env file loading

Note that if your local environment has environment variables set, they will take precedence over the values in the .env file as is standard practice. If you're seeing unexpected behaviour, it can be due to the environment variables set in your local environment. To verify, you can use the --override-env flag to make sure the .env file takes precedence.

cdf --override-env <command>

atenționare

The .env files can contain secrets — do not check them into version control repositories. The .env extension is added to the .gitignore file created in your project directory.

Sign-in flow environment variables

The Cognite Toolkit supports the following sign-in flows. The environment variables they expect are listed below.

client_credentials

This sign-in flow sets up a service account with client credentials. It's the recommended sign-in flow for CI/CD pipelines. The sign-in flow requires that you have created a group and service account credentials in your identity provider.

Description	Environment variable
The variable selecting the login flow, set to client_credentials to use client credentials flow.	LOGIN_FLOW
The cluster where your CDF project is running, for example, westeurope-1.	CDF_CLUSTER
The CDF project name, for example, myproject.	CDF_PROJECT
The client ID of the application/service account in your identity provider.	IDP_CLIENT_ID
The client secret of the application/service account in your identity provider.	IDP_CLIENT_SECRET

The token URL of your identity provider.	IDP_TOKEN_URL
The CDF URL. The URL to your CDF project.	CDF_URL

device_code

This sign-in flow lets you authenticate as a user. It's the recommended sign-in flow for local development. The sign-in flow requires that you have authorization to give consent to the application in your identity provider.
