s3_sync - Efficiently upload multiple files to S3

New in version 2.3.

Synopsis

  • The S3 module is great, but it is very slow for a large volume of files- even a dozen will be noticeable. In addition to speed, it handles globbing, inclusions/exclusions, mime types, expiration mapping, recursion, cache control and smart directory mapping.

Requirements (on host that executes module)

  • boto
  • boto3 >= 1.4.4
  • botocore
  • python >= 2.6

Options

parameter required default choices comments
aws_access_key
 no
AWS access key. If not set then the value of the AWS_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variable is used.
aliases: ec2_access_key, access_key
aws_secret_key
 no
AWS secret key. If not set then the value of the AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variable is used.
aliases: ec2_secret_key, secret_key
bucket
 yes
Bucket name.
cache_control
(added in 2.4)
 no
This is a string.
Cache-Control header set on uploaded objects.
Directives are separated by commmas.
delete
(added in 2.4)
 no
Remove remote files that exist in bucket but are not present in the file root.
ec2_url
 no
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.
exclude
 no .*
Shell pattern-style file matching.
Used after include to remove files (for instance, skip "*.txt")
For multiple patterns, comma-separate them.
file_change_strategy
 no date_size
  • force
  • checksum
  • date_size
Difference determination method to allow changes-only syncing. Unlike rsync, files are not patched- they are fully skipped or fully uploaded.
date_size will upload if file sizes don't match or if local file modified date is newer than s3's version
checksum will compare etag values based on s3's implementation of chunked md5s.
force will always upload all files.
file_root
 yes
File/directory path for synchronization. This is a local path.
This root path is scrubbed from the key name, so subdirectories will remain as keys.
include
 no *
Shell pattern-style file matching.
Used before exclude to determine eligible files (for instance, only "*.gif")
For multiple patterns, comma-separate them.
key_prefix
 no
In addition to file path, prepend s3 path with this prefix. Module will add slash at end of prefix if necessary.
mime_map
 no
Dict entry from extension to MIME type. This will override any default/sniffed MIME type. For example {".txt": "application/text", ".yml": "appication/text"}
mode
 yes push
  • push
sync direction.
permission
 no
  • private
  • public-read
  • public-read-write
  • authenticated-read
  • aws-exec-read
  • bucket-owner-read
  • bucket-owner-full-control
Canned ACL to apply to synced files.
Changing this ACL only changes newly synced files, it does not trigger a full reupload.
profile
(added in 1.6)
 no
Uses a boto profile. Only works with boto >= 2.24.0.
region
 no
The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region
aliases: aws_region, ec2_region
security_token
(added in 1.6)
 no
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
validate_certs
(added in 1.5)
 no yes
  • yes
  • no
When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

Notes

Note

  • 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 http://boto.readthedocs.org/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
