Overview

This class is the starting point for working with AWS Identity and Access Management (IAM).

For more information about IAM:

Credentials

You can setup default credentials for all AWS services via AWS.config:

AWS.config(
  :access_key_id => 'YOUR_ACCESS_KEY_ID',
  :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')

Or you can set them directly on the IAM interface:

iam = AWS::IAM.new(
  :access_key_id => 'YOUR_ACCESS_KEY_ID',
  :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')

Account Summary

You can get account level information about entity usage and IAM quotas directly from an IAM interface object.

summary = iam.

puts "Num users: #{summary[:users]}"
puts "Num user quota: #{summary[:users_quota]}"

For a complete list of summary attributes see the #account_summary method.

Account Aliases

Currently IAM only supports a single account alias for each AWS account. You can set the account alias on the IAM interface.

iam. = 'myaccountalias'
iam.
#=> 'myaccountalias'

You can also remove your account alias:

iam.
iam.
#=> nil

Access Keys

You can create up to 2 access for your account and 2 for each user. This makes it easy to rotate keys if you need to. You can also deactivate/activate access keys.

# get your current access key
old_access_key = iam.access_keys.first

# create a new access key
new_access_key = iam.access_keys.create
new_access_key.credentials
#=> { :access_key_id => 'ID', :secret_access_key => 'SECRET' }

# go rotate your keys/credentials ...

# now disable the old access key
old_access_key.deactivate!

# go make sure everything still works ...

# all done, lets clean up
old_access_key.delete

Users can also have access keys:

u = iam.users['someuser']
access_key = u.access_keys.create
access_key.credentials
#=> { :access_key_id => 'ID', :secret_access_key => 'SECRET' }

See AccessKeyCollection and AccessKey for more information about working with access keys.

Users & Groups

Each AWS account can have multiple users. Users can be used to easily manage permissions. Users can also be organized into groups.

user = iam.users.create('JohnDoe')
group = iam.groups.create('Developers')

# add a user to a group
user.groups.add(group)

# remove a user from a group
user.groups.remove(group)

# add a user to a group
group.users.add(user)

# remove a user from a group
group.users.remove(user)

See User, UserCollection, Group and GroupCollection for more information on how to work with users and groups.

#change_password(old_password, new_password) ⇒ nil

Changes the web password associated with the current IAM user. In order to change your password you must configure the sdk to use your IAM user credentials.

To change a user password, you must be using credentials from the user you want to change:

# pass in a key pair generated for the user you want to change 
# the password for
iam = AWS::IAM.new(:access_key_id => '...', :secret_access_key => '...)
iam.change_password('old-password', 'new-password')

  • old_password (String)
  • new_password (String)
