aws_s3 – manage objects in S3

Synopsis

  • This module allows the user to manage S3 buckets and the objects within them. Includes support for creating and deleting both objects and buckets, retrieving objects as files or strings and generating download links. This module has a dependency on boto3 and botocore.

Requirements

The below requirements are needed on the host that executes this module.

  • boto
  • boto3
  • botocore
  • python >= 2.6

Parameters

Parameter Choices/Defaults Comments
aws_access_key
string
AWS access key id. If not set then the value of the AWS_ACCESS_KEY environment variable is used.

aliases: ec2_access_key, access_key
aws_secret_key
string
AWS secret key. If not set then the value of the AWS_SECRET_KEY environment variable is used.

aliases: ec2_secret_key, secret_key
bucket
- / required
Bucket name.
debug_botocore_endpoint_logs
boolean
added in 2.8
    Choices:
  • no ←
  • yes
Use a botocore.endpoint logger to parse the unique (rather than total) "resource:action" API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used.
dest
-
The destination file path when downloading an object/key with a GET operation.
dualstack
boolean
added in 2.7
    Choices:
  • no ←
  • yes
Enables Amazon S3 Dual-Stack Endpoints, allowing S3 communications using both IPv4 and IPv6.
Requires at least botocore version 1.4.45.
ec2_url
string
Url to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
encrypt
boolean
    Choices:
  • no
  • yes ←
When set for PUT mode, asks for server-side encryption.
encryption_kms_key_id
-
added in 2.7
KMS key id to use when encrypting objects using aws:kms encryption. Ignored if encryption is not aws:kms
encryption_mode
-
added in 2.7
    Choices:
  • AES256 ←
  • aws:kms
What encryption mode to use if encrypt is set
expiration
-
Default:
600
Time limit (in seconds) for the URL generated and returned by S3/Walrus when performing a mode=put or mode=geturl operation.
headers
-
Custom headers for PUT operation, as a dictionary of 'key=value' and 'key=value,key=value'.
ignore_nonexistent_bucket
boolean
    Choices:
  • no
  • yes
Overrides initial bucket lookups in case bucket or iam policies are restrictive. Example: a user may have the GetObject permission but no other permissions. In this case using the option mode: get will fail without specifying ignore_nonexistent_bucket: True.
marker
-
Specifies the key to start with when using list mode. Object keys are returned in alphabetical order, starting with key after the marker in order.
max_keys
-
Default:
1000
Max number of results to return in list mode, set this if you want to retrieve fewer than the default 1000 keys.
metadata
-
Metadata for PUT operation, as a dictionary of 'key=value' and 'key=value,key=value'.
mode
- / required
    Choices:
  • get
  • put
  • delete
  • create
  • geturl
  • getstr
  • delobj
  • list
Switches the module behaviour between put (upload), get (download), geturl (return download url, Ansible 1.3+), getstr (download object as string (1.3+)), list (list keys, Ansible 2.0+), create (bucket), delete (bucket), and delobj (delete object, Ansible 2.0+).
object
-
Keyname of the object inside the bucket. Can be used to create "virtual directories", see examples.
overwrite
-
Default:
"always"
Force overwrite either locally on the filesystem or remotely with the object/key. Used with PUT and GET operations. Boolean or one of [always, never, different], true is equal to 'always' and false is equal to 'never', new in 2.0. When this is set to 'different', the md5 sum of the local file is compared with the 'ETag' of the object/key in S3. The ETag may or may not be an MD5 digest of the object data. See the ETag response header here https://docs.aws.amazon.com/AmazonS3/latest/API/RESTCommonResponseHeaders.html

aliases: force
permission
-
Default:
"private"
This option lets the user set the canned permissions on the object/bucket that are created. The permissions that can be set are 'private', 'public-read', 'public-read-write', 'authenticated-read' for a bucket or 'private', 'public-read', 'public-read-write', 'aws-exec-read', 'authenticated-read', 'bucket-owner-read', 'bucket-owner-full-control' for an object. Multiple permissions can be specified as a list.
prefix
-
Default:
""
Limits the response to keys that begin with the specified prefix for list mode
profile
string
Uses a boto profile. Only works with boto >= 2.24.0.
region
string
AWS region to create the bucket in. If not set then the value of the AWS_REGION and EC2_REGION environment variables are checked, followed by the aws_region and ec2_region settings in the Boto config file. If none of those are set the region defaults to the S3 Location: US Standard. Prior to ansible 1.8 this parameter could be specified but had no effect.

aliases: aws_region, ec2_region
retries
-
Default:
0
On recoverable failure, how many times to retry before actually failing.
rgw
boolean
    Choices:
  • no ←
  • yes
Enable Ceph RGW S3 support. This option requires an explicit url via s3_url.
s3_url
-
S3 URL endpoint for usage with Ceph, Eucalyptus and fakes3 etc. Otherwise assumes AWS.

aliases: S3_URL
security_token
string
AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used.

aliases: access_token
src
-
The source file path when performing a PUT operation.
validate_certs
boolean
    Choices:
  • no
  • yes ←
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
version
-
Version ID of the object inside the bucket. Can be used to get a specific version of a file if versioning is enabled in the target bucket.

Notes

Note

  • In 2.4, this module has been renamed from s3 into aws_s3.
  • If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN, AWS_REGION or EC2_REGION
  • Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
  • AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
