* `source` - location of folder to sync

delete: true

```
|
||||
|
||||
Both `acl` and `content_type` can be passed as a string value to apply to all files, or as a map to apply to a subset of files.
|
||||
|
||||
For example:
|
||||
|
||||
```yaml
|
||||
publish:
|
||||
s3_sync:
|
||||
acl:
|
||||
"public/*": public-read
|
||||
"private/*": private
|
||||
content_type:
|
||||
".svg": image/svg+xml
|
||||
region: "us-east-1"
|
||||
bucket: "my-bucket.s3-website-us-east-1.amazonaws.com"
|
||||
access_key: "970d28f4dd477bc184fbd10b376de753"
|
||||
secret_key: "9c5785d3ece6a9cdefa42eb99b58986f9095ff1c"
|
||||
source: folder/to/archive
|
||||
target: /target/location
|
||||
delete: true
|
||||
```
|
||||
|
||||
In the case of `acl` the key of the map is a glob as matched by [filepath.Match](https://golang.org/pkg/path/filepath/#Match). If there are no matches in your settings for a given file, the default is `"private"`.
|
||||
|
||||
The `content_type` field the key is an extension including the leading dot `.`. If you want to set a content type for files with no extension, set the key to the empty string `""`. If there are no matches for the `content_type` of any file, one will automatically be determined for you.
