Unreleased

Consider Implementing:

  • Consider coding ebs_optimized against list of ebs-optimized instances.
  • Expose ephemeral block device support.
  • Expose lifecycle hook support.
  • Expose scheduling support.
  • Added support for Autoscaling "StepScaling" policy.
  • Break notifications out to support aggregation of groups and notifications to a single SNS topic.
  • Extend multi-part user_data mechanism to support more use cases.

0.3.0 (March 24, 2017)

BACKWARDS INCOMPATIBILITIES / NOTES:

  • The following parameters were renamed:
  • ebs_device_name to ebs_vol_device_name
  • ebs_snapshot_id to ebs_vol_snapshot_id
  • The min_adjustment_magnitude parameter for SimpleScaling policies has been retired.

IMPROVEMENTS / NEW FEATURES:

  • Conditional support for the following parameters:
  • associate_public_ip_address
  • default_cooldown
  • desired_capacity
  • ebs_vol_encrypted
  • ebs_vol_size
  • enabled_metrics
  • enable_monitring
  • force_delete
  • instance_profile
  • key_name
  • placement_group
  • protect_from_scale_in
  • suspended_processes
  • termination_policies
  • root_vol_size
  • spot_price
  • user_data
  • Support for specifying multiple security groups in addition to the one created by the module using the security_groups parameter.
  • Support for io1 root & EBS volumes.
  • Support for EBS volume not not originating from a snapshot.
  • Added managed_by=terraform tag to ASG managed instances.
  • Instance Name tags can now be based on the instance-id by setting the instance_based_naming_enabled parameter to true.
  • Support for an arbitrary number of tags to be applied to each instance.

BUG FIXES:

  • Fixed inconsistent tagging between asg and asg_elb resources

0.2.0 (May 16, 2016)

BACKWARDS INCOMPATIBILITIES / NOTES:

  • Resources names updated in several places for standardization. Will cause extra churn in existing environments.
  • The built in egress security group rule has been remove from the module (see here and here). Be sure to declare your own egress rule when using the module (see here and here)

IMPROVEMENTS:

  • Introduced deterministic conditional logic for the following scenarios:
  • Specification of an EBS snapshot to associate with the launch configuration.
  • Specification of ELB(s) to associate with the auto scaling group.
  • Specification of percentage based simple auto scaling policies.
  • All variables explicitly typed per HashiCorp best practices.
  • Added name prefixing to security group and launch configuration resources.
  • Exposed associate_public_ip_address parameter on launch configuration.
  • Exposed placement_tenancy parameter on launch configuration.
  • Exposed root volume configuration parameters on launch configuration.
  • Exposed EBS volume configuration parameters on launch configuration.
  • Exposed wait_for_capacity_timeout parameter on auto scaling group.

0.1.2 (Apr 27, 2016)

BACKWARDS INCOMPATIBILITIES / NOTES:

  • Changed the default value for ebs_optimized from true -> false. This setting is more compatible with the majority of instance types.

IMPROVEMENTS:

  • Name for aws_launch_configuration.
  • Fixed name label for aws_autoscaling_group.
  • Fixed name label for auto-scaling group's security group.

0.1.1 (Dec 1, 2015)

IMPROVEMENTS:

  • Updated template_file usage for 0.6.7 to remove deprecation warnings [GH-9]
  • Added ASG name to module outputs [GH-8]
  • Added default Name tag to auto scaling groups [GH-6]

BUG FIXES:

  • Updated lifecycle hooks to prevent dependency cycles during destroy [GH-5]
  • Added proper lifecycle management to allow launch configuration updates [GH-2]
  • Removed sg- from ASG security group name [GH-1]

0.1.0 (Oct 26, 2015)

  • Initial Release
