module: iam
short_description: Manage IAM users, groups, roles and keys
description:
- Allows for the management of IAM users, groups, roles and access keys.
version_added: "2.0"
options:
iam_type:
description:
- Type of IAM resource
required: true
default: null
choices: [ "user", "group", "role"]
name:
description:
- Name of IAM resource to create or identify
required: true
new_name:
description:
- When state is update, will replace name with new_name on IAM resource
required: false
2015-06-05 20:09:02 +02:00
default: null
new_path:
description:
- When state is update, will replace the path with new_path on the IAM resource
required: false
2015-06-05 20:09:02 +02:00
default: null
state:
description:
- Whether to create, delete or update the IAM resource. Note, roles cannot be updated.
required: true
default: null
choices: [ "present", "absent", "update" ]
path:
description:
- When creating or updating, specify the desired path of the resource. If state is present, it will replace the current path to match what is passed in when they do not match.
required: false
default: "/"
access_key_state:
description:
- When type is user, it creates, removes, deactivates or activates a user's access key(s). Note that actions apply only to keys specified.
required: false
default: null
choices: [ "create", "remove", "active", "inactive"]
key_count:
description:
- When access_key_state is create it will ensure this quantity of keys are present. Defaults to 1.
required: false
default: '1'
access_key_ids:
description:
- A list of the keys that you want impacted by the access_key_state paramter.
groups:
description:
- A list of groups the user should belong to. When update, will gracefully remove groups not listed.
required: false
default: null
password:
description:
- When type is user and state is present, define the users login password. Also works with update. Note that always returns changed.
required: false
default: null
update_password:
required: false
default: always
choices: ['always', 'on_create']
description:
- C(always) will update passwords if they differ. C(on_create) will only set the password for newly created users.
aws_secret_key:
description:
- AWS secret key. If not set then the value of the AWS_SECRET_KEY environment variable is used.
required: false
default: null
aliases: [ 'ec2_secret_key', 'secret_key' ]
aws_access_key:
description:
- AWS access key. If not set then the value of the AWS_ACCESS_KEY environment variable is used.
required: false
default: null
aliases: [ 'ec2_access_key', 'access_key' ]
notes:
- 'Currently boto does not support the removal of Managed Policies, the module will error out if your user/group/role has managed policies when you try to do state=absent. They will need to be removed manually.'
