terraform-aws-code-deploy

Terraform module to provision AWS Code Deploy app and group.

---

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

module "example" {  
  source = "cloudposse/code-deploy/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"
}

Inputs

Name	Description	Type	Default	Required
additional_tag_map	Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id. This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration.	map(string)	{}	no
alarm_configuration	Configuration of deployment to stop when a CloudWatch alarm detects that a metric has fallen below or exceeded a defined threshold. alarms: A list of alarms configured for the deployment group. ignore_poll_alarm_failure: Indicates whether a deployment should continue if information about the current state of alarms cannot be retrieved from CloudWatch.	object({ alarms = list(string) ignore_poll_alarm_failure = bool })	null	no
attributes	ID element. Additional attributes (e.g. workers or cluster) to add to id, in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element.	list(string)	[]	no
auto_rollback_configuration_events	The event type or types that trigger a rollback. Supported types are DEPLOYMENT_FAILURE and DEPLOYMENT_STOP_ON_ALARM.	string	"DEPLOYMENT_FAILURE"	no
autoscaling_groups	A list of Autoscaling Groups associated with the deployment group.	list(string)	[]	no

create_default_sns_topic	Whether to create default SNS topic through which notifications are sent.	bool	true	no
delimiter	Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
deployment_style	Configuration of the type of deployment, either in-place or blue/green, you want to run and whether to route deployment traffic behind a load balancer. deployment_option: Indicates whether to route deployment traffic behind a load balancer. Possible values: WITH_TRAFFIC_CONTROL, WITHOUT_TRAFFIC_CONTROL. deployment_type: Indicates whether to run an in-place deployment or a blue/green deployment. Possible values: IN_PLACE, BLUE_GREEN.	object({ deployment_option = string deployment_type = string })	null	no
descriptor_formats	Describe additional descriptors to be output in the descriptors output map. Map of maps. Keys are names of descriptors. Values are maps of the form {<br> format = string<br> labels = list(string)<br>} (Type is any so the map values can later be enhanced to provide additional options.) format is a Terraform format string to be passed to the format() function. labels is a list of labels, in order, to pass to format() function. Label values will be normalized before being passed to format() so they will be identical to how they appear in id. Default is {} (descriptors output will be empty).	any	{}	no
ec2_tag_filter	The Amazon EC2 tags on which to filter. The deployment group includes EC2 instances with any of the specified tags. Cannot be used in the same call as ec2TagSet.	set(object({ key = string type = string value = string }))	[]	no
ec2_tag_set	A list of sets of tag filters. If multiple tag groups are specified, any instance that matches to at least one tag filter of every tag group is selected. key: The key of the tag filter. type: The type of the tag filter, either KEY_ONLY, VALUE_ONLY, or KEY_AND_VALUE. value: The value of the tag filter.	set(object( { ec2_tag_filter = set(object( { key = string type = string value = string } )) } ))	[]	no

label_key_case	Controls the letter case of the tags keys (label names) for tags generated by this module. Does not affect keys of tags passed in via the tags input. Possible values: lower, title, upper. Default value: title.	string	null	no
label_order	The order in which the labels (ID elements) appear in the id. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.	list(string)	null	no
label_value_case	Controls the letter case of ID elements (labels) as included in id, set as tag values, and output by this module individually. Does not affect values of tags passed in via the tags input. Possible values: lower, title, upper and none (no transformation). Set this to title and set delimiter to "" to yield Pascal Case IDs.
