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

cloud-fusion aws 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 = cloud-fusion aws iam-user-credentials get --account-id 123456789012 --username 'my-iam-user' --access-key 'AKIAIOSFODNN7EXAMPLE' --credential-process

Use case of aws config-switch

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

For Linux & Darwin (MacOS)

This works with 2 bash script, namely _awsp and _awsr

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

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

Using the command without the aliases will have no effect

For Windows

This works with 2 powershell script, namely _awsp.ps1 and _awsr.ps1

Post installing the app, create 2 aliases in $PROFILE (i.e. $HOME\Documents\PowerShell\Microsoft.PowerShell_profile.ps1) file.

## cloud fusion setup
Set-Alias awsp "_awsp.ps1"
Set-Alias awsr "_awsr.ps1"

Use case of gcp config-switch

Switches between gcloud configurations and compute/region, similar in spirit to aws config-switch.

Unlike the AWS version, this applies the change directly and globally via gcloud config configurations activate / gcloud config set compute/region rather than exporting env vars into the calling shell. That means the two aliases below are a convenience, not a requirement — running the commands directly also works — but also that there's no per-shell isolation: the change is visible to every shell and every tool that reads gcloud config (Terraform, Docker, other terminals, etc.).

Requires the gcloud CLI on PATH and an authenticated account.

cloud-fusion gcp config-switch configuration
cloud-fusion gcp config-switch region

• configuration also updates the application-default credentials quota project (gcloud auth application-default set-quota-project) to match the chosen configuration's project. Pass --skip-quota-project to skip this.
• region lists regions via the Compute Engine API, so it needs a project set on the active configuration with that API enabled.

For Linux & Darwin (MacOS)

This works with 2 bash script, namely _gcpc and _gcpr

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

## cloud fusion setup
alias gcpc="source _gcpc"
alias gcpr="source _gcpr"

For Windows

This works with 2 powershell script, namely _gcpc.ps1 and _gcpr.ps1

Post installing the app, create 2 aliases in $PROFILE (i.e. $HOME\Documents\PowerShell\Microsoft.PowerShell_profile.ps1) file.

## cloud fusion setup
Set-Alias gcpc "_gcpc.ps1"
Set-Alias gcpr "_gcpr.ps1"

Migrating from aws-fusion

aws-fusion has been renamed to cloud-fusion to make room for other cloud providers alongside AWS. AWS commands now live under an aws sub-command:

pip uninstall aws-fusion
pip install cloud-fusion

If you use the aws fusion alias or any credential_process line in ~/.aws/config, re-run cloud-fusion aws init and update the credential_process commands above.
