Yet Another AWS SSO - sync up AWS CLI v2 SSO login session to legacy CLI v1 credentials

yawsso

Yet Another AWS SSO - sync up AWS CLI v2 SSO login session to legacy CLI v1 credentials.

Prerequisite

• Required Python >= 3.6
• Required AWS CLI v2
• Assume you have already setup AWS SSO for your organization

Main Use Case

• Install latest from PyPI like so:

pip install yawsso

• Do your per normal SSO login and, have at least one active SSO session cache:

aws sso login --profile dev

• To sync for all named profiles in config (i.e. lazy consensus), then just:

yawsso

• To sync default profile and all named profiles, do:

yawsso --default

• To sync default profile only, do:

yawsso --default-only

• To sync for selected named profile, do:

yawsso -p dev

• To sync for multiple selected named profiles, do:

yawsso -p dev prod

• To sync for default profile as well as multiple selected named profiles, do:

yawsso --default -p dev prod

• To sync for all named profiles start with prefix pattern lab*, do:

(zsh)
yawsso -p 'lab*'

(bash)
yawsso -p lab*

• To sync for all named profiles start with lab* as well as dev and prod, do:

yawsso -p 'lab*' dev prod

• Print help to see other options:

yawsso -h

• Then, continue per normal with your daily tools. i.e.
  • cdk deploy ...
  • terraform apply ...
  • cw ls -p dev groups
  • awsbw -L -P dev
  • sqsmover -s main-dlq -d main-queue
  • ecs-cli ps --cluster my-cluster

Additional Use Case

Rename Profile on Sync

• Say, you have the following profile in your $HOME/.aws/config:

[profile dev]
sso_start_url = https://myorg.awsapps.com/start
sso_region = ap-southeast-2
sso_account_id = 123456789012
sso_role_name = AdministratorAccess
region = ap-southeast-2
output = json
cli_pager =

• You want to populate access token as, say, profile name foo in $HOME/.aws/credentials:

[foo]
region = ap-southeast-2
aws_access_key_id = XXX
aws_secret_access_key = XXX
aws_session_token = XXX
...

• Do like so:

yawsso -p dev:foo

• Then, you can export AWS_PROFILE=foo and use foo profile!

Export Tokens

• Use -e flag if you want a temporary copy-paste-able time-gated access token for an instance or external machine.

🤚 PLEASE USE THIS FEATURE WITH CARE SINCE ENVIRONMENT VARIABLES USED ON SHARED SYSTEMS CAN GIVE UNAUTHORIZED ACCESS TO PRIVATE RESOURCES:

• Please note that, it uses default profile if no additional arguments pass.

yawsso -e
export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=xxx
export AWS_SESSION_TOKEN=xxx

• This use case is especially tailored for those who use default profile and, who would like to PIPE commands as follows.

aws sso login && yawsso -e | pbcopy

• Otherwise, for a named profile, do:

yawsso -p dev -e

• Or, right away export credentials into the current shell environment variables, do:

yawsso -p dev -e | source /dev/stdin 

Note: ☝️ are mutually exclusive with the following 👇 auto copy into your clipboard. Choose one, a must!

• If you have pyperclip package installed, yawsso will copy access tokens to your clipboard instead.

yawsso -e
Credentials copied to your clipboard for profile 'default'

• You may pip install pyperclip or, together with yawsso as follows.

pip install 'yawsso[all]'

Login

• You can also use yawsso subcommand login to SSO login then sync all in one go.

🙋‍♂️ NOTE: It uses default profile if optional argument --profile is absent

yawsso login -h
yawsso login

• Otherwise you can pass the login profile as follows:

yawsso login --profile dev

• Due to lazy consensus design, yawsso will sync all named profiles once SSO login has succeeded. If you'd like to sync only upto this login profile then use --this flag to limit as follows.

👉 Login using default profile and sync only upto this default profile

yawsso login --this

👉 Login using named profile dev and sync only upto this dev profile

yawsso login --profile dev --this

Login then Export token

• Exporting access token also support with login subcommand as follows:

👉 Login using default profile, sync only upto this default profile and, print access token

yawsso login -e

👉 Login using named profile dev, sync only upto this dev profile and, print access token

yawsso login --profile dev -e

Develop

• Create virtual environment, activate it and then:

make install
make test
python -m yawsso --trace version
