1. I have a sveltekit app that I'd like to set up cognito identities for. Once a user creates an account using the sveltekit front end, I want that user to be able to use that same role to access a seperate data pipeline application that running in a platform aclled modal

    TypeScript

    To achieve this setup, you'll need to create a Cognito User Pool for user authentication and an Identity Pool to grant users access to AWS resources. You'll also need to configure roles and permissions so that users can access your data pipeline application on Modal.

    Here's a brief explanation of the steps:

    1. Create a Cognito User Pool.
    2. Create a Cognito Identity Pool.
    3. Attach roles to the Identity Pool.

    Below is the Pulumi program in TypeScript to set this up:

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; // Create a Cognito User Pool const userPool = new aws.cognito.UserPool("userPool", { name: "sveltekit-user-pool", autoVerifiedAttributes: ["email"], }); // Create a Cognito User Pool Client const userPoolClient = new aws.cognito.UserPoolClient("userPoolClient", { userPoolId: userPool.id, generateSecret: false, callbackUrls: ["https://your-sveltekit-app.com/callback"], logoutUrls: ["https://your-sveltekit-app.com/logout"], allowedOauthFlows: ["code"], allowedOauthScopes: ["email", "openid", "profile"], supportedIdentityProviders: ["COGNITO"], }); // Create a Cognito Identity Pool const identityPool = new aws.cognito.IdentityPool("identityPool", { identityPoolName: "sveltekit-identity-pool", allowUnauthenticatedIdentities: false, cognitoIdentityProviders: [{ clientId: userPoolClient.id, providerName: userPool.endpoint.apply(endpoint => `cognito-idp.${aws.config.region}.amazonaws.com/${endpoint}`), }], }); // Create IAM roles for authenticated and unauthenticated users const authenticatedRole = new aws.iam.Role("authenticatedRole", { assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({ Federated: "cognito-identity.amazonaws.com", }), }); const unauthenticatedRole = new aws.iam.Role("unauthenticatedRole", { assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({ Federated: "cognito-identity.amazonaws.com", }), }); // Attach policies to the roles (example policy, adjust as needed) const authenticatedRolePolicy = new aws.iam.RolePolicy("authenticatedRolePolicy", { role: authenticatedRole.id, policy: pulumi.output({ Version: "2012-10-17", Statement: [{ Effect: "Allow", Action: ["mobileanalytics:PutEvents", "cognito-sync:*", "execute-api:Invoke"], Resource: "*", }], }), }); // Attach roles to the Identity Pool const identityPoolRoleAttachment = new aws.cognito.IdentityPoolRoleAttachment("identityPoolRoleAttachment", { identityPoolId: identityPool.id, roles: { authenticated: authenticatedRole.arn, unauthenticated: unauthenticatedRole.arn, }, }); export const userPoolId = userPool.id; export const userPoolClientId = userPoolClient.id; export const identityPoolId = identityPool.id;

    This program sets up a Cognito User Pool and an Identity Pool, defines IAM roles for authenticated and unauthenticated users, and attaches these roles to the Identity Pool. Adjust the policies and roles as needed to match the permissions required by your data pipeline application on Modal.


  2. can I use these identity pools for access to other applications as well? I have some jobs that can be executed in modal I'd like to give the user access to.

    TypeScript

    Yes, you can use AWS Cognito Identity Pools to grant users access to other applications, including executing jobs in Modal. By configuring the Identity Pool with appropriate IAM roles and policies, you can manage user permissions for various AWS services and external applications.

    Below is a Pulumi program that sets up an AWS Cognito Identity Pool, creates IAM roles for authenticated and unauthenticated users, and attaches policies to allow access to execute jobs in Modal.

    import * as pulumi from "@pulumi/pulumi"; import * as aws from "@pulumi/aws"; // Create a Cognito User Pool const userPool = new aws.cognito.UserPool("userPool", { name: "sveltekit-user-pool", autoVerifiedAttributes: ["email"], }); // Create a Cognito User Pool Client const userPoolClient = new aws.cognito.UserPoolClient("userPoolClient", { userPoolId: userPool.id, generateSecret: false, callbackUrls: ["https://your-sveltekit-app.com/callback"], logoutUrls: ["https://your-sveltekit-app.com/logout"], allowedOauthFlows: ["code"], allowedOauthScopes: ["email", "openid", "profile"], supportedIdentityProviders: ["COGNITO"], }); // Create a Cognito Identity Pool const identityPool = new aws.cognito.IdentityPool("identityPool", { identityPoolName: "sveltekit-identity-pool", allowUnauthenticatedIdentities: false, cognitoIdentityProviders: [{ clientId: userPoolClient.id, providerName: userPool.endpoint.apply(endpoint => `cognito-idp.${aws.config.region}.amazonaws.com/${endpoint}`), }], }); // Create IAM roles for authenticated and unauthenticated users const authenticatedRole = new aws.iam.Role("authenticatedRole", { assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({ Federated: "cognito-identity.amazonaws.com", }), }); const unauthenticatedRole = new aws.iam.Role("unauthenticatedRole", { assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({ Federated: "cognito-identity.amazonaws.com", }), }); // Attach policies to the roles (example policy, adjust as needed) const authenticatedRolePolicy = new aws.iam.RolePolicy("authenticatedRolePolicy", { role: authenticatedRole.id, policy: pulumi.output({ Version: "2012-10-17", Statement: [{ Effect: "Allow", Action: ["mobileanalytics:PutEvents", "cognito-sync:*", "execute-api:Invoke", "modal:ExecuteJobs"], Resource: "*", }], }), }); const unauthenticatedRolePolicy = new aws.iam.RolePolicy("unauthenticatedRolePolicy", { role: unauthenticatedRole.id, policy: pulumi.output({ Version: "2012-10-17", Statement: [{ Effect: "Allow", Action: ["mobileanalytics:PutEvents", "cognito-sync:*"], Resource: "*", }], }), }); // Attach roles to the Identity Pool const identityPoolRoleAttachment = new aws.cognito.IdentityPoolRoleAttachment("identityPoolRoleAttachment", { identityPoolId: identityPool.id, roles: { authenticated: authenticatedRole.arn, unauthenticated: unauthenticatedRole.arn, }, }); export const userPoolId = userPool.id; export const userPoolClientId = userPoolClient.id; export const identityPoolId = identityPool.id;

    In this program, the authenticatedRolePolicy includes permissions to execute jobs in Modal (modal:ExecuteJobs). You can adjust the policy to include other permissions as needed.
