S3 api tools

Metadata may be set when the file is uploaded or it can be updated subsequently. S3 files are stored in S3 buckets. Buckets can be created, listed, configured, and deleted. The bucket configuration can be read and the bucket contents can be listed. In addition to the s3 Python module, this package contains a command line tool also named s3. The installation is successful if you can import s3 and run the command line tool. The following commands must produce no errors:. Buckets store files.

Buckets may be created and deleted. They may be listed, configured, and loaded with files. The configuration can be read, and the files in the bucket can be listed. Bucket names must be unique across S3 so it is best to use a unique prefix on all bucket names. S3 forbids underscores in bucket names, and although it allows periods, these confound DNS and should be avoided.

For example, at Prometheus Research we prefix all of our bucket names with: com-prometheus-. However, that string is readily available if need be, because the response returned by requests. An S3 file name consists of a bucket and a key. This pair of strings uniquely identifies the file within S3. The S3Name class is instantiated with a key and a bucket; the key is required and the bucket defaults to None.

If no bucket is given or the bucket is None and there is no default bucket then a ValueError is raised. Although S3 storage is flat: buckets contain keys, S3 lets you impose a directory tree structure on your bucket by using a delimiter in your keys.

Additional http headers may be sent using the methods which write data. These methods accept an optional headers argument which is a python dict. The headers control various aspects of how the file may be handled. S3 supports a variety of headers. These are not discussed here. Those headers whose key begins with the special prefix: x-amz-meta- are considered to be metadata headers and are used to set the metadata attributes of the file.

The methods which read files also return the metadata which consists of only those response headers which begin with x-amz-meta-. To facilitate the transfer of data between S3 and applications various classes were defined which correspond to data returned by S3.

An XML string consists of a series of nested tags. It also contains specific instructions for setting up s3curl to work with the S3 compatible API. Typically, when configuring a third-party tool to work with the S3 compatible API, you need to provide this information:.

This is the fully qualified hostname of the tenant in the context of which you plan to create and manage buckets and the objects in them. For example, if the tenant name is europe and the HCP system domain name is hcp. Even the free version allows users to back up files locally as well as to S3 servers , export files and folders to zip files, create bootable USBs, retain unlimited file versions, and more.

There is a maximum file size limit of 5 GB, but the freeware version of Cloudberry Explorer should provide all the functionality needed for those with modest S3 management needs. This raises the maximum file size to 5 TB and adds a load of useful features, such as encryption and compression, multi-threading, FTP support, upload rules, search, and more.

Freeware customers must rely on community support, while Pro customers benefit from direct email support from Cloudberry. The company also offers subscription-based managed backup services which can back up data to your Amazon S3 account.

It provides an attractive GUI interface with which to manage, share, edit using an editor of your choice and synchronize files stored in your S3 account. A favorite feature of ours is client-side encryption using Cryptomator vaults. This is another dedicated interface tool for managing your Amazon S3 account, albeit one only available for Windows.

New feature additions and Pull Requests can easily cause regressions and break existing compatibility. Dependency on other SDKs or libraries could mask bugs. Instead s3verify creates its own handcrafted HTTP requests and sends them to the user specified server. For each possible valid input the correct response must be returned.
