Is it possible to download a file from AWS s3 without AWS cli? In my production server I would need to download a config file which is in S3 bucket.
I was thinking of having Amazon Systems Manger run a script that would download the config (YAML files) from the S3. But we do not want to install AWS cli on the production machines. How can I go about this?
You would need some sort of program to call the Amazon S3 API to retrieve the object. For example, a PowerShell script (using AWS Tools for Windows PowerShell) or a Python script that uses the AWS SDK.
You could alternatively generate an Amazon S3 pre-signed URL, which would allow a private object to be downloaded from Amazon S3 via a normal HTTPS call (eg curl). This can be done easily using the AWS SDK for Python, or you could code it yourself without using libraries (it's a bit more complex).
In all examples above, you would need to provide the script/program with a set of IAM Credentials for authenticating with AWS.
