Use PutBucketTagging with an Amazon SDK or CLI

The following command applies a tagging configuration to a bucket named my-bucket:

aws s3api put-bucket-tagging --bucket my-bucket --tagging file://tagging.json

The file tagging.json is a JSON document in the current folder that specifies tags:

{
   "TagSet": [
     {
       "Key": "organization",
       "Value": "marketing"
     }
   ]
}

Or apply a tagging configuration to my-bucket directly from the command line:

aws s3api put-bucket-tagging --bucket my-bucket --tagging 'TagSet=[{Key=organization,Value=marketing}]'

Example 1: This command applies two tags to a bucket named cloudtrail-test-2018: a tag with a key of Stage and a value of Test, and a tag with a key of Environment and a value of Alpha. To verify that the tags were added to the bucket, run Get-S3BucketTagging -BucketName bucket_name. The results should show the tags that you applied to the bucket in the first command. Note that Write-S3BucketTagging overwrites the entire existing tag set on a bucket. To add or delete individual tags, run the Resource Groups and Tagging API cmdlets, Add-RGTResourceTag and Remove-RGTResourceTag. Alternatively, use Tag Editor in the Amazon Management Console to manage S3 bucket tags.

Write-S3BucketTagging -BucketName cloudtrail-test-2018 -TagSet @( @{ Key="Stage"; Value="Test" }, @{ Key="Environment"; Value="Alpha" } )

Example 2: This command pipes a bucket named cloudtrail-test-2018 into the Write-S3BucketTagging cmdlet. It applies tags Stage:Production and Department:Finance to the bucket. Note that Write-S3BucketTagging overwrites the entire existing tag set on a bucket.

Get-S3Bucket -BucketName cloudtrail-test-2018 | Write-S3BucketTagging -TagSet @( @{ Key="Stage"; Value="Production" }, @{ Key="Department"; Value="Finance" } )
