on GitHub

4.0.0 (2022-06-14)

⚠ BREAKING CHANGES

• Refactor module to align with current standards, add missing addtional Redshift resources to module (#61)

List of backwards incompatible changes

• Minimum supported version of Terraform AWS provider updated to v4.17 to support latest resources
• Minimum supported version of Terraform updated to v1.0
• create variable added to control whether all resources are created or not. This means that all resources now use the zeroth index [0] in the resource name

Additional changes

Added

• Support for generating a random password for the master_password
• aws_redshift_snapshot_schedule resource including the variables and outputs used to support it
• aws_redshift_snapshot_schedule_association resource including the variables and outputs used to support it
• aws_redshift_scheduled_action resource including support for creating the IAM role and policies plus the associated variables and outputs to support
• aws_redshift_usage_limit resource including the variables and outputs used to support it
• aws_redshift_authentication_profile resource including the variables and outputs used to support it
• aws_redshift_cluster_iam_roles resource including the variables and outputs used to support it

Modified

• number_of_nodes default value of 3 changed to 1
• cluster_version default value of "1.0" changed to null
• master_username default value of "awsuser" added
• encrypted default value changed to true
• By default, a randomly generated password of length 16 is used for the master_password
• master_password variable marked as sensitive

Removed

• None

Variable and output changes

1. Removed variables:

• Parameter Group
  • wlm_json_configuration, require_ssl, use_fips_ssl, enable_user_activity_logging, max_concurrency_scaling_clusters, enable_case_sensitive_identifier have been replaced by the use of parameter_group_parameters where any/all of these values can be set as well as others not listed here.

1. Renamed variables:

• Cluster

  • Cluster variables that per the AWS provider do not start with cluster_ have been renamed to remove the cluster_ prefix.
  • enable_logging, logging_bucket_name, and logging_s3_key_prefix have been replaced with the top level variable logging where their equivalent parameters enable, bucket_name, and s3_key_prefix are set, and support for new parameters log_destination_type, and log_exports have been added.
  • snapshot_copy_destination_region, automated_snapshot_retention_period, snapshot_copy_grant_name have been replaced with the top level variable snapshot_copy where their equivalent parameters destination_region, retention_period, and grant_name are set.
  • iam_roles has been renamed to iam_role_arns to match API of aws_redshift_cluster_iam_roles resource now used

• Parameter Group

  • cluster_parameter_group ->parameter_group_family

• Subnet Group

  • redshift_subnet_group_name -> subnet_group_name: Note: this was not previously used in the manner it was intended. The cluster_identifier was used as the name of the subnet group. This has now been corrected
  • subnets -> subnet_ids to match AWS provider

1. Added variables:

• Cluster

  • create which affects all resources
  • create_random_password and random_password_length to support generating a random password for the master_password
  • apply_immediately
  • aqua_configuration_status
  • availability_zone
  • availability_zone_relocation_enabled
  • default_iam_role_arn
  • maintenance_track_name
  • manual_snapshot_retention_period
  • cluster_timeouts to support setting create, update, and delete timeout durations

• Parameter Group

  • create_parameter_group was added to replace length(var.parameter_group_name) > 0 logic
  • parameter_group_name
  • parameter_group_parameters which allows users to set any number of parameters, replacing the previously hardcoed parameters
  • parameter_group_tags

• Subnet Group

  • create_subnet_group was added to replace var.redshift_subnet_group_name == "" logic
  • subnet_group_description was added to replace the hardcoded description used previously
  • subnet_group_tags

1. Removed outputs:

   • None

2. Renamed outputs:

   • The preceding redshift_ prefix has been removed from all outputs

3. Added outputs:

   • cluster_dns_name
   • parameter_group_arn
   • subnet_group_arn
