Depreciation Notice

We no longer maintain this repository. Instead we have moved to a new tool Authum

aws-jumpcloud

Allows you to authenticate with AWS using your JumpCloud credentials. Based on ideas from aws-vault, aws-okta, and jumpcloud_aws.

Features

• Uses your JumpCloud account to authenticate to Amazon Web Services, via SAML single sign-on (SSO), and retrieves a set of temporary AWS security credentials.
• Uses the native OS keychain to store JumpCloud credentials and AWS temporary IAM credentials. Built atop Keyring for Python, with support for macOS, Windows, and Linux.
• Supports multiple AWS profiles, to handle multiple AWS integrations in your JumpCloud account.
• Supports JumpCloud multi-factor authentication; prompts you for your MFA code when needed.

Why a new tool just for JumpCloud?

• Adding SAML support to aws-vault would be a big project.
• aws-okta doesn't look amenable to adding a second identity provider -- not to mention, it would go against the name.
• jumpcloud_aws was broken when I tried to use it. It also didn't support MFA or more than one integration.
• There are also a few other tools on GitHub which might work well, I didn't try all of them.

Installation

via Homebrew

brew tap CirrusMD/aws-jumpcloud https://github.com/CirrusMD/homebrew-aws-jumpcloud.git
brew install aws-jumpcloud

Manual

Prerequisite: Python 3.8 or newer.

If you're running macOS but don't have Python 3, I recommend installing it with Homebrew. The command brew install python will install it without breaking your existing Python installation.

Migrating from ~/.aws credentials

If you were previously using persistent credentials in ~/.aws/config, here are some tips for moving to JumpCloud SSO:

• Since you won't be using those persistent credentials, remove that file when installing aws-jumpcloud.
• If you've been setting AWS_DEFAULT_PROFILE in your ~/.bash_profile (or equivalent), you should stop setting that, since you're not using the standard AWS config file
• On the other hand, since AWS profiles point to a specific region, you'll probably want to add AWS_DEFAULT_REGION to your ~/.bash_profile (or equivalent). (export AWS_DEFAULT_REGION=us-west-1, for example.)
• If nothing else is using the IAM access keys previously in your ~/.aws/config, disable or delete the access keys from the IAM Console. From that page you can search for the access key itself, or browse/search by username.

Usage

Context-sensitive help is available for every command in aws-jumpcloud.

# Show general help about aws-jumpcloud
$ aws-jumpcloud --help

# Show the most detailed information about the exec command
$ aws-jumpcloud exec --help

Adding a profile

Typically you'll start by adding a profile for your primary AWS integration. This will prompt you for the JumpCloud URL, which you can grab from the JumpCloud Console in your browser. Right-click on any AWS integration icon and choose "Copy Link Address."

$ aws-jumpcloud add duff
Enter the JumpCloud SSO URL for duff: <url copied from the JumpCloud Console>
Profile duff added.

Listing profiles

You can view all profiles registered in your aws-jumpcloud keychain:

$ aws-jumpcloud list

Profile           AWS Account       AWS Role       IAM session expires
================  ================  =============  =====================
duff              544300394404      JumpCloudDevs  <no active session>

Running a command

Once you've created a profile, you can use it to run a command, like aws s3 ls.

The first time you login to JumpCloud, you will be prompted for your JumpCloud email and password, along with an MFA token if necessary. aws-jumpcloud will store your email and password in your OS keychain for future logins, but you'll be prompted for the MFA token every time.

$ aws-jumpcloud exec duff -- aws s3 ls
Enter your JumpCloud email address: duffman@duff-beer.com
Enter your JumpCloud password:
JumpCloud login details saved in your OS keychain.
Enter your JumpCloud multi-factor auth code: 798708

Behind the scenes, aws-jumpcloud has used SAML single sign-on to authenticate with Amazon Web Services and request a set of temporary security credentials. The temporary credentials are cached in your operating system's keychain for an hour, so you can continue to run AWS commands without needing to authenticate again.

$ aws-jumpcloud exec duff -- aws s3 ls s3://duff-logs-us-east-1/

Removing profiles

You can remove a profile if you no longer need it:

$ aws-jumpcloud remove duff
Profile duff and temporary IAM session removed.

And you can clear aws-jumpcloud's entire keychain if necessary:

$ aws-jumpcloud remove --all

All configuration profiles, temporary IAM sessions, and JumpCloud login
credentials have been removed from your OS keychain.

Advanced features

Exporting credentials into your environment

It's a small hassle to put aws-jumpcloud exec profile before every AWS-related command that you run. The aws-jumpcloud export command displays the export commands that will load your temporary AWS credentials directly into your shell. This will let you run AWS commands directly from the shell, although it won't recognize when your temporary credentials have expired.

If you're not using multi-factor authentication, you can put a command like this into your .bash_profile to load the AWS into every shell:

eval "$(aws-jumpcloud export duff)"

If you use multi-factor authentication, the command needs to be a little more complicated. Before callling aws-jumpcloud you must first make sure you have active AWS credentials for the given profile. The two-step dance is necessary because we can't safely prompt for your MFA token when output isn't going to stdout, as is the case with $().

aws-jumpcloud exec duff -- true && eval "$(aws-jumpcloud export duff)"

Adding a profile with an assumed role

You may find that you need to interact with AWS using a different IAM role than the one connected to JumpCloud. For example, your JumpCloud integration may only grant read-only access to resources in the AWS Console, and you need to assume an expanded role in order to make changes. Or, if your company has more than one AWS account, you may login to a single AWS account, and then assume a role in another account to access the resources in that account.

aws-jumpcloud profiles can be configured to automatically assume another IAM role when you establish a session. Each time you establish a new AWS session using such a profiles, aws-jumpcloud will login through JumpCloud, and then immediately call the AssumeRole API to request credentials for the other role. The role can be in your own AWS account or in another AWS account.

To configure a profile to assume a role on each login, add the --role parameter to the aws-jumpcloud add command. Here's an example of assuming a role in the same account:

$ aws-jumpcloud add --role=deployer duff-deployer
Enter the JumpCloud SSO URL for duff-deployer: <url copied from the JumpCloud Console>
Profile duff-deployer added.

You can specify the assumed role by name or ARN, which allows you to assume a role in another AWS account:

$ aws-jumpcloud add --role=arn:aws:iam::619893369699:role/deployer subaccount-deployer
Enter the JumpCloud SSO URL for subaccount-deployer: <url copied from the JumpCloud Console>
Profile duff-deployer added.

If the role requires an External ID to be provided to the AssumeRole API, that must be specified when creating the aws-jumpcloud profile, using the --external-id parameter. For example:

$ aws-jumpcloud add --role=deployer --external-id=QgbnxwqT2w duff-deployer
Enter the JumpCloud SSO URL for duff-deployer: <url copied from the JumpCloud Console>
Profile duff-deployer added.

The AWS IAM User Guide contains more information about assuming IAM roles.

Rotating credentials

After a profile's temporary IAM credentials expire, aws-jumpcloud will automatically delete the credentials from its keychain. New temporary credentials will automatically be requested the next time you attempt to use that profile. However, you can also rotate the credentials at any time and request new credentials immediately.

$ aws-jumpcloud rotate duff
Temporary IAM session for duff removed.
Using JumpCloud login details from your OS keychain.
Enter your JumpCloud multi-factor auth code: 788149
Attempting SSO authentication to Amazon Web Services...

AWS temporary session rotated; new session valid until Thu Nov 15 20:49:38 2018 UTC.

1Password support

If the 1Password CLI is installed, aws-jumpcloud will automatically use your JumpCloud credentials and MFA token from 1Password. The credentials must be stored in an item named jumpcloud

Initial Setup

To set up the 1Password CLI for the first time, download and install the CLI and run the following commands with your own 1Password information from the emergency kit and correct password.

$ op signin guild-education first.last@guildeducation.com
Enter the Secret Key for first.last@guildeducation.com at guild-education.1password.com: VERY-SECRET-THING from your emergency kit
Enter the password for first.last@guildeducation.com at guild-education.1password.com: ur1Passwordpassword

Credential Rotation

To automatically rotate expired credentials for a given profile when you fire up your shell, add the following to your .(bash|zsh|whatever)rc

aws-jumpcloud-rotate() {
  if [ "$(aws-jumpcloud is-active $1)" != "1" ]; then
    eval $(op signin duff-beer)
    aws-jumpcloud rotate $1
  fi
}

aws-jumpcloud-rotate duff

The "duff-beer" refers to the subdomain of your 1Password acount (e.g., the "duff-beer" of your "duff-beer.1password.com" 1Password account). You may export OP_SUBDOMAIN=duff-beer in your .(bash|zsh|whatever)rc to have aws-jumpcloud automatically refresh expired 1Password CLI sessions.

To manually rotate credentials from your terminal:

eval $(op signin duff-beer)
aws-jumpcloud rotate duff

Developing
