Note that this argument is needed only when a stream is being uploaded to s3 and the size is larger than 5GB. expected-size (string): This argument specifies the expected size of a stream in terms of bytes. If you don’t do this you’ll exceed the number of parts allowed in a multi-part upload and your request will fail. If you are writing to S3 files that are bigger than 5GB, you have to use the -expected-size option so that AWS CLI can calculate the proper number of parts in the multi-part upload. No intermediary file is created in the executing machine and the content is just kept in memory in a streaming fashion during the different phases of the pipeline.

This output stream is then piped to the AWS CLI again and the s3 cp command will start to write it to the destination bucket.

imagemin will start immediately to process the stream and produce an output stream representing the optimized image.

The standard output is then piped to imagemin and used as input stream.

S3 will start to stream the binary content of s3://my-images/image.png to the standard output.

What will happen behind the scene with this pipeline of commands is the following: Using this newly acquired piece of knowledge, we now know we can do something like this to write content from the standard output directly to a file in S3:Īws s3 cp s3://my-images/image.png - | imagemin | aws s3 cp - s3://my-images-optimized/image.png To make it simple, when running aws s3 cp you can use the special argument - to indicate the content of the standard input or the content of the standard output (depending on where you put the special argument). Downloading as a stream is not currently compatible The following cp command downloads an S3 object locally as a stream to The following cp command uploads a local file stream from standardĭownloading an S3 object as a local file stream Check out the comprehensive documentation at AWS CLI Command Reference.WARNING:: PowerShell may alter the encoding of or add a CRLF to piped

In the example above, the s3 command's sync command 'recursively copies new and updated files from the source directory to the destination. Valid output formats ( documented here) are.Valid region names ( documented here) are Region The prompts will look like AWS Access Key ID, and you will be able to keep the configured value by hitting return. In the future you can change any of these values by running aws cli again. On the first run of aws configure you will just see.

You can install AWS CLI for any major operating system: Getting set up with AWS CLI is simple, but the documentation is a little scattered. With AWS CLI, that entire process took less than three seconds: Happily, Amazon provides AWS CLI, a command line tool for interacting with AWS. That is a tedious task in the browser: log into the AWS console, find the right bucket, find the right folder, open the first file, click download, maybe click download a few more times until something happens, go back, open the next file, over and over. The other day I needed to download the contents of a large S3 folder.
