jmpr

What this is?

Tooling to permit AWS account navigation

How does it work?

But seriously, it does some cool stuff in really cool ways...

How do I use it?

To get started using jmpr install via pip: pip install jmpr.

(You may need to pip install boto3 pyyaml to preinstall the dependencies)

To run jmpr use jmpr -y yourfile.yml

Use the following gitlab-ci.yml configuration to run in a GitLab CI/CD Pipeline:

Deploy Test:
 stage: deploy
 before_script:
   - pip install . --quiet
 script:
   - jmpr -y test.yaml

AWS Organization Configuration

TODO: EXPLAIN HOW TO SETUP THE AWS ORGS CONFIG

AWS Account Configuration

TODO: EXPLAIN HOW TO CONFIGURE AWS ACCOUNTS TO BE USED. BOTH ORG ACCOUNTS AND NON ORG ACCOUNTS

Your jmpr Manifest File

jmpr accepts yaml files as input. These files define your entire authentication infrastructure. Including Accounts, Roles, Users, and Policies.

Example Users

users:
  - name: testuser
    additional_path: "something"
    cloud: AWS
    target_roles:
      - account: 540253368830
        role_name: ROLE-ADMIN
        region: us-west-2
      - account: 879397242692
        role_name: ROLE-DEV
      - account: 611424868009
        role_name: ROLE-NEW-ROLE
      - account: 333422963795
        role_name: ROLE-BILLING
      - account: 355841365103
        role_name: ROLE-BILLING

Example Roles

roles:
  - name: ROLE-ADMIN
    import:
      - arn:aws:iam::aws:policy/AdministratorAccess
  - name: ROLE-RO
    import:
      - arn:aws:iam::aws:policy/ReadOnlyAccess
      - arn:aws:iam::aws:policy/job-function/Billing
  - name: ROLE-BILLING
    import:
      - arn:aws:iam::aws:policy/job-function/Billing
  - name: ROLE-FOO
    import:
      - arn:aws:iam::aws:policy/ReadOnlyAccess
      - arn:aws:iam::aws:policy/job-function/Billing

Example Accounts

accounts:
  test_acct_1:
    account_number: 616552976502

  test_acct_2:
    name: My Account
    account_number: 426276006285
    color: ffbd05
    default_region: us-east-1

  test_acct_3:
    name: Your Account
    account_number: 343074669674
    color: 225f91
    default_region: us-east-2
    purge: false
    allowed_roles:
      - admin
      - ro
      - billing

  '420355987158':
    name: No One's Account

For more examples please see test.yml.

Developer Notes:

To work on this project the following two commands will be your best friends

pip install . --no-deps - Quickly install the local repo via pip without worring about dependencies

jmpr -y test.yaml - Runs jmpr on the test yaml file that is designed to exersize the yaml parser

The core library file is cloudassets.py.

The jmpr cli configuration is cli.py

Note on paths:

AWS IAM fetch and create are carried out only using the name of an entity (user, group, role) by a client associated with an account. Path does not play into AWS IAM entity retrieval or creation.

Paths are embedded in resulting entity ARN's, and ARNs are used to relate entities to each other, for instance in an 'assume role policy'. In addition, paths can be used in policies to include or exclude.

So:

• Entities (users, roles, etc.) with the same name and different paths will collide
• Entities specified with an ARN that does not include the correct path will not be properly referenced.

Maintaining and managing YAML or JSON ARNs including path is likely to introduce frequent errors and failures.

In consequence, the jmpr approach constructs entities in the way that they are fetched, by account and name, retaining any path information as decoration.

When ARNs are needed for a call, the ARN is constructed dynamically in code from the attributes of the entity, which can include the path decoration. This ensures consistent ARNs.

Initially in early release entity paths are guaranteed consistent and all equal to the asset_path, but in later releases entity-specific paths may be introduced so long as they are not embedded in ARNs.
