Getting Started

Once the CLI is installed, run the following commands to login and assume roles:

# Saves a GitHub token with a user:email scope to ~/.saml-to/github-token.json
saml-to login github

# List available roles to assume
saml-to list-roles

If no logins or roles are available, an administrator for an AWS account should complete the initial setup.

Add the --help flag to any command for available options.

Assuming Roles

Interactive prompt for roles to assume:

saml-to assume

Or, if the full role name is known:

saml-to assume arn:aws:iam::123456789012:role/some-role

Alternatively, use the shorthand:

# Any distinct part of the role names in from saml-to list-roles will match
saml-to assume some-role # match by the role name
saml-to assume 123456789012 # match by the account ID

Check out the documentation for assume.

Setting Environment Variables

The --headless flag will output an expression to update your shell environment with a role.

bash, zsh, etc...

Use a subshell ($(...)) to set AWS_* related environment variables:

$(saml-to assume some-role --headless)
aws s3api list-buckets # or any desired `aws` command

Powershell

Use Invoke-Expression (iex) to set AWS_* related environment variables:

iex (saml-to assume some-role --headless)
aws s3api list-buckets # or any desired `aws` command
