Say you have a file be it a pdf, word document or even a large iso. You can use Openstack to temporarily share this file with others.
This assumes you are authenticated with Openstack API already.(Openstack Client Access)
Make sure you have a tempurl key generated and attached to your account (this only has to be done once and not every time you want to share a file)
#generate a key with uuidgen
$ uuidgen
$ 6b4139c0-3eda-4e3f-8bcf-97b0f19014b9
$ swift post -m 'Temp-URL-KEY:6b4139c0-3eda-4e3f-8bcf-97b0f19014b9'
The rest needs to be done each time you want to share a file or renew a url:
#First check account to collect data.
$swift stat
#From the output you will need the “Account” and “Meta Temp-Url-Key”

#Create a container or folder to place the file in:
$swift post iso
#Upload your file or object to the container
$swift upload iso /home/user/rhel7.iso
#Next, create a tempurl (filling in the brackets with the information we retrieved from the "swift stat" command above).
$swift tempurl 3600 /v1/{Account}/iso/rhel7.iso {Meta Temp-Url-Key}

#The resulting output should be appended to the swift endpoint. In this instance it would look something like:
Note: The url you generate will only be available for the amount of time (in seconds) you provided in the $swift tempurl command above. After which you'll need to generate another url.
