1. Directly use aws-fusion command
2. Use it via aws cli alias with aws fusion

Commands

• init
• open-browser
• store-iam-user-credentials
• get-iam-user-credentials
• generate-okta-device-auth-credentials

---

Usage of init

Try aws-fusion init --help for detailed parameter

Initilize fusion app with creation of aws fusion alias

---

Usage of open-browser

Try aws-fusion open-browser --help for detailed parameter

• Make AWS credentials available via aws profile
• Execute the script: aws-fusion open-browser --profile my-profile
• :tada: Your browser opens, and you are signed in into the AWS console

Use cases

This only works with assume-role and federated-login, doesn't work with IAM user or user session.

IAM assume role

Profiles that use IAM roles pull credentials from another profile, and then apply IAM role permissions.

In the following examples, iam-user is the source profile for credentials and iam-assume-role borrows the same credentials then assumes a new role.

Credentials file

[profile iam-user]
aws_access_key_id=AKIAIOSFODNN7EXAMPLE
aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

Config file

[profile iam-user]
region = us-east-1
output = json

[profile iam-assume-role]
source_profile = iam-user
role_arn = arn:aws:iam::777788889999:role/user-role
role_session_name = my-session
region = ap-south-1
output = json

Federated login

Using IAM Identity Center, you can log in to Active Directory, a built-in IAM Identity Center directory, or another IdP connected to IAM Identity Center. You can map these credentials to an AWS Identity and Access Management (IAM) role for you to run AWS CLI commands.

In the following examples, using aws-sso profile assumes sso-read-only-role on 111122223333 account.

Config file

[profile aws-sso]
sso_session = my-sso-session
sso_account_id = 111122223333
sso_role_name = sso-read-only-role
role_session_name = my-session
region = us-east-1
output = json

[sso-session my-sso-session]
sso_region = us-east-2
sso_start_url = https://my-sso-portal.awsapps.com/start
sso_registration_scopes = sso:account:access

    --secret-key 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY' \
    --account-id '123456789012' \
    --username 'my-iam-user'

Usage of get-iam-user-credentials

Try aws-fusion get-iam-user-credentials --help for detailed parameter

Retrieve AWS credentials from system default credential store. Optionally plug the CLI to aws external credential process.

Use cases

Configure aws config file to use credential process

Config file

[profile iam-user]
region = us-east-1
output = json
credential_process = aws-fusion get-iam-user-credentials --account-id 123456789012 --username 'my-iam-user' --access-key 'AKIAIOSFODNN7EXAMPLE' --credential-process

Usage of generate-okta-device-auth-credentials

Try aws-fusion generate-okta-device-auth-credentials --help for detailed parameter

Simplifies the process of obtaining AWS session credentials using SAML assertion from Okta device authentication

Use cases

Configure aws config file to use credential process

Config file

[profile iam-user]
region = us-east-1
output = json
credential_process = aws-fusion generate-okta-device-auth-credentials --org-domain my.okta.com --oidc-client-id 0pbs4fq1q2vbGoFkC1m7 --aws-acct-fed-app-id 0oa8z9xa8BS9b2AFb1t7 --aws-iam-role arn:aws:iam::123456789012:role/PowerUsers --credential-process
