Use case of open-browser

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

Usa case of iam-user-credentials store

To store IAM user credential in the system credential store for best security rather than plain text ~/.aws/credentials file.

Manually the save the credential in the store using

aws-fusion iam-user-credentials store \
    --access-key 'AKIAIOSFODNN7EXAMPLE' \
    --secret-key 'wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY' \
    --account-id '123456789012' \
    --username 'my-iam-user'

---

Use case of iam-user-credentials get

Configure aws config file to use credential process

Config file

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

Use case of okta device-auth

Configure aws config file to use credential process

Config file

[profile iam-user]
region = us-east-1
output = json
credential_process = aws-fusion okta device-auth --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

---

Use case of config-switch

A special of utility script to help easily switch profile and region

This works with 2 bash script, namely _awsp and _awsr

Using the command without the bash script will have no effect

Post installing the app, create 2 aliases in .bashrc or .zshrc file.

## aws fusion setup
alias awsp="source _awsp"
alias awsr="source _awsr"
