# s3bro! A handy s3 cli tool

Overview

It’s your s3 friend (bro). You’ll often find yourself having to run complex CLI/AWS commands in order to execute tasks against S3. Let’s say you need to restore all your keys from S3 Glacier storage class, if you’ve attempted this task, you’ve probably come to the realization, that the AWS CLI does not allow for an easy manner to execute this in “batch”.

Subsequently, you would need to make use of a combination of AWS CLI commands and pipe it to additional commands in order to obtain your desired result. In addition to this complexity, it would restore key by key, very slowly.

S3bro, however, offers you a solution to the above problem and others common situations where you have to run complex s3 commands, by utilizing multiprocessing/threading. This means that you can expedite tasks a lot faster than using the normal method. Oh, did I mention… in a much more elegant way. This is a python cli that will abstract a big portion of the work for you.

Why would you run the two following commands to wipe your bucket:

>>>
aws s3api list-object-versions --bucket rsavordelli --output json --query
    'Versions\[\].\[Key, VersionId\]' | jq -r '.\[\] | "--key '\\''" + .\[0\] + "'\\''
         --version-id " + .\[1\]' |  xargs -L1 aws s3api delete-object --bucket rsavordelli
aws s3api list-object-versions --bucket rsavordelli --output json --query
     'DeleteMarkers\[\].\[Key, VersionId\]' | jq -r '.\[\] | "--key '\\''" + .\[0\] + "'\\''
         --version-id " + .\[1\]' |  xargs -L1 aws s3api delete-object --bucket rsavordelli

if you can run this?

>>>
s3bro purge --bucket rsavordelli

what if you need to restore all your keys from glacier storage class? Or just some of them?

>>>

  -b, --bucket TEXT               bucket name  [required]
  -p, --prefix TEXT               prefix

                                  will make the restore to include all
                                  versions excluding delete markers

  -ex, --exclude TEXT             Do not restore if the key name matches with a
                                  given pattern, you can add multiple patterns
                                  by inputting

Details

the option –log-level can be useful to debug errors/behaviors.

>>>
DEBUG - similar to boto3 debug level with additional information
WARNING - will print some threading information and Keys excluded during the iteration (exclude, include, storage-class, delete-marker, etc)

• the option –workers allows you to specify how many workers will consume the list. Calculate max 5 workers per core

• the option –update-restore-date can be used to “extend” a key that is already restored. It will send a new “expiry” date to the object

purge

Delete all keys in the bucket - as simple as that. It will delete versions, delete markers. Everything

Options

>>>
Usage: s3bro purge [OPTIONS] [PURGE]...
  delete all the bucket content
Options:
  -b, --bucket TEXT               Bucket name  [required]
  -p, --prefix TEXT               prefix name - optional
  --yes                           first confirmation
  --log-level [INFO|ERROR|DEBUG|WARNING]
                                  logging type
  --help                          Show this message and exit.

Details

• The script has two confirmations. The first can be by-passed with –yes. The second one ask you to confirm the bucket name.

• The second confirmation can be avoided if you create a Tag in the Bucket with Key: s3bro_delete and Value: yes . That will by pass the bucket name confirmation.
