Parameters

Examples

# Minimal example using environment vars or instance role credentials
# Fetch all hosts in us-east-1, the hostname is the public DNS if it exists, otherwise the private IP address
plugin: aws_ec2
regions:
  - us-east-1

# Example using filters, ignoring permission errors, and specifying the hostname precedence
plugin: aws_ec2
boto_profile: aws_profile
regions: # populate inventory with instances in these regions
  - us-east-1
  - us-east-2
filters:
  # all instances with their `Environment` tag set to `dev`
  tag:Environment: dev
  # all dev and QA hosts
  tag:Environment:
    - dev
    - qa
  instance.group-id: sg-xxxxxxxx
# ignores 403 errors rather than failing
strict_permissions: False
# note: I(hostnames) sets the inventory_hostname. To modify ansible_host without modifying
# inventory_hostname use compose (see example below).
hostnames:
  - tag:Name=Tag1,Name=Tag2  # return specific hosts only
  - tag:CustomDNSName
  - dns-name
  - private-ip-address

# Example using constructed features to create groups and set ansible_host
plugin: aws_ec2
regions:
  - us-east-1
  - us-west-1
# keyed_groups may be used to create custom groups
strict: False
keyed_groups:
  # add e.g. x86_64 hosts to an arch_x86_64 group
  - prefix: arch
    key: 'architecture'
  # add hosts to tag_Name_Value groups for each Name/Value tag pair
  - prefix: tag
    key: tags
  # add hosts to e.g. instance_type_z3_tiny
  - prefix: instance_type
    key: instance_type
  # create security_groups_sg_abcd1234 group for each SG
  - key: 'security_groups|json_query("[].group_id")'
    prefix: 'security_groups'
  # create a group for each value of the Application tag
  - key: tags.Application
    separator: ''
  # create a group per region e.g. aws_region_us_east_2
  - key: placement.region
    prefix: aws_region
# set individual variables with compose
compose:
  # use the private IP address to connect to the host
  # (note: this does not modify inventory_hostname, which is set via I(hostnames))
  ansible_host: private_ip_address
