Module: lb-s3-bucket

Terraform module to provision an S3 bucket with built in IAM policy to allow AWS Load Balancers to ship access logs.

Usage

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 "s3_bucket" {
source = "cloudposse/lb-s3-bucket/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"

namespace = "eg"
stage = "test"
name = "bucket"
}

additional_tag_mapAdditional 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
allow_ssl_requests_onlyRequire requests to use Secure Socket Layer (HTTPS/SSL).booltrueno
attributesID 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
bucket_nameBucket name. If provided, the bucket will be created with this name instead of generating the name from the contextstringnullno
contextSingle object for setting entire context at once.
See description of individual variables for details.
Leave string and numeric variables as null to use default value.
Individual variable settings (non-null) override settings in context object,
except for attributes, tags, and additional_tag_map, which are merged.

delimiterDelimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.
stringnullno
descriptor_formatsDescribe 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
enable_glacier_transition(Deprecated, use lifecycle_configuration_rules instead)
Enables the transition to AWS Glacier which can cause unnecessary costs for huge amount of small files
booltrueno
enabledSet to false to prevent the module from creating any resourcesboolnullno
environmentID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'stringnullno
expiration_days(Deprecated, use lifecycle_configuration_rules instead)
Number of days after which to expunge the objects
number90no
force_destroyWhen true, permits a non-empty S3 bucket to be deleted by first deleting all objects in the bucket.
THESE OBJECTS ARE NOT RECOVERABLE even if they were versioned and stored in Glacier.
Must be set false unless force_destroy_enabled is also true.
boolfalseno
glacier_transition_days(Deprecated, use lifecycle_configuration_rules instead)
Number of days after which to move the data to the Glacier Flexible Retrieval storage tier
number60no
id_length_limitLimit id to this many characters (minimum 6).
Set to 0 for unlimited length.
Set to null for keep the existing setting, which defaults to 0.
Does not affect id_full.
numbernullno
label_key_caseControls 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.
stringnullno
label_orderThe 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)nullno
label_value_caseControls 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.
Default value: lower.
stringnullno
labels_as_tagsSet of labels (ID elements) to include as tags in the tags output.
Default is to include all labels.
Tags with empty values will not be included in the tags output.
Set to [] to suppress all generated tags.
Notes:
The value of the name tag, if included, will be the id, not the name.
Unlike other null-label inputs, the initial setting of labels_as_tags cannot be
changed in later chained modules. Attempts to change it will be silently ignored.

lifecycle_configuration_rulesA list of S3 bucket v2 lifecycle rules, as specified in terraform-aws-s3-bucket"
These rules are not affected by the deprecated lifecycle_rule_enabled flag.
NOTE: Unless you also set lifecycle_rule_enabled = false you will also get the default deprecated rules set on your bucket.

lifecycle_rule_enabledDEPRECATED: Defaults to false, use lifecycle_configuration_rules instead.
When true, configures lifecycle events on this bucket using individual (now deprecated) variables."
boolfalseno
nameID element. Usually the component or solution name, e.g. 'app' or 'jenkins'.
This is the only ID element not also included as a tag.
The "name" tag is set to the full id string. There is no tag with the value of the name input.
stringnullno
namespaceID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally uniquestringnullno

number30no
regex_replace_charsTerraform regular expression (regex) string.
Characters matching the regex will be removed from the ID elements.
If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.
