How to use AWS CLI with DreamObjects


  • a command-line tool for uploading, retrieving, and managing data in Amazon S3 and other Cloud Storage Service Providers that use the S3 protocol such as DreamHost DreamObjects.
  • best suited for power users who don’t fear command line.
  • ideal for scripts, automated backups triggered from cron, and so on.

The following instructions help you install and configure AWS CLI to work with DreamObjects.

Installing AWS CLI

Depending on the operating system you are running, there are several options.

For Windows there are files in .msi format that can be installed directly.

For Mac and Linux, the suggested installation is through python “pip”. To do this, run the following command on your local computer:

[user@localhost]$ pip install awscli

To install the client on a DreamHost shared, VPS or dedicated server will require the use of python virtualenv and then using its “pip” to install the AWS CLI client locally with the same pip install command above. Please see the Python article for specifics on how to accomplish this.

Configuring AWS CLI

This client has features that apply to many services offered by Amazon, but for this tutorial we only are concerned with using the S3 functionality in combination with DreamObjects. To use the S3 features, you must ensure a few things. Run the following command to input your access and secret keys for AWS CLI to store them encrypted for you. Accept the default region and output format by hitting enter.

[user@localhost]$ aws configure
AWS Access Key ID [None]:
AWS Secret Access Key [None]:
Default region name [None]:
Default output format [None]:

Example Commands

Making a bucket

[user@localhost]$ aws --endpoint-url s3 mb s3://newbucketname
make_bucket: s3://newbucketname/

Listing all buckets

[user@localhost]$ aws --endpoint-url s3 ls
2016-01-27 20:14:46 newbucketname

Uploading a file into a bucket

[user@localhost]$ aws --endpoint-url s3 cp testfile.txt s3://newbucketname/testfile.txt
upload: ./testfile.txt to s3://newbucketname/testfile.txt

Listing the contents of a bucket

[user@localhost]$ aws --endpoint-url s3 ls s3://newbucketname
2016-01-27 19:30:21       8803 testfile.txt

Downloading a file from a bucket

[user@localhost]$ aws --endpoint-url s3 cp s3://newbucketname/testfile.txt testfile.txt
download: s3://newbucketname/testfile.txt to ./testfile.txt

Deleting a file in a bucket

[user@localhost]$ aws --endpoint-url s3 rm s3://newbucketname/testfile.txt
delete: s3://newbucketname/testfile.txt

Deleting an empty bucket

[user@localhost]$ aws --endpoint-url s3 rb s3://newbucketname/
remove_bucket: s3://newbucketname/

Sync a directory and its files to or from a bucket

This will only upload new and changed files, and not delete any files. You can specify other params such as –delete to remove files from the destination that aren’t on the source. An additional useful flag is –acl which accepts values such as “private” or “public-read”.

[user@localhost]$ aws --endpoint-url s3 sync syncdir s3://newbucketname/
upload: syncdir/file3 to s3://newbucketname/file3
upload: syncdir/file1 to s3://newbucketname/file1
upload: syncdir/file2 to s3://newbucketname/file2
