Create S3 pre-signed URL
We'll setup a server using MinIO and generate a pre-signed URL using the Python SDK so we can upload a triage collection.
Next step is to generate a pre-signed URL so we can upload data to it.
The example code we're going to use is get_presigned_url.py from https://github.com/minio/minio-py/blob/master/examples/get_presigned_url.py
You'll need Python3, and the minio library
$ sudo apt install python3-pip
$ pip3 install minio
Edit this python script in your favourite editor.
from minio import Minio
client = Minio(
"minio.yourdomain.com.au:9000",
access_key="default_username",
secret_key="default_password",
secure=True,
)
If you're still using the default credentials we set earlier (minioadmin/minioadmin) then enter those here. It's obviously best practice to not use the default credentials.
$ python3 get_presigned_url.py
If the script executed successfully without errors, you'll have three URLs printed on the screen. We're interested in the second URL as this is what we'll be using to upload our data using UAC. If you don't have a need for the other two URLs and intend to administer objects manually via the web interface, then comment out the other two DELETE/GET URL generation sections.
The name of the object created with this URL is 'my-object'. If you want a custom name, you'll need to edit the python script and change 'my-object' to something else. Likewise, if you want to store data in a different bucket, replace 'my-bucket' with another name. If you were using this in production you'd prompt for the desired values to store client data in specific buckets, with specific names.
You should have a pre-signed URL which looks similar to the following;
https://minio.yourdomain.com.au:9000/my-bucket/my-object?response-content-type=application%2Fjson&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=[redacted]
You've now generated a pre-signed URL using MinIO's python SDK, and you're ready to upload your UAC collection.
