Cloud Files directory listing
My last holiday took me to Morocco, where me and a couple of friends used motorbikes to travel through the country. To have something to show off back home, we used small cameras mounted on the bikes to film everything. At the end of the trip, our group had filmed about 10 gigabytes of footage and I was put in charge to gather and distribute these files amongst ourselves.
I uploaded all the footage - roughly 55 videos - to a Cloud Files container, b ut obviously I didn’t want to give my portal username and password to my friends. Also, there is no option to generate an index file within Cloud Files, so the only option left to me was to send everyone the 55 video URLs separately. Clearly, a different solution was needed. And so I built one myself.
The script below will retrieve a list of files within a container, convert that list into an HTML filelist and then upload that HTML-file into your Cloud Files container. You just have to make sure that you enable the Static Website option in the container settings in Cloud Files and you’re set.
The script is written in Bash and depends on httpie and jq, both which are available as packages on the Ubuntu operating system.
To install httpie and jq, please type the following:
apt-get install httpie jq
After httpie and jq have been installed, copy the code below and save it as cfindex.sh on your (Linux) server:
#!/bin/bash
[[ -n "$3" ]] || { echo "Usage: $0 username apikey container"; exit 0 ; }
ENDPOINT='lon.identity.api.rackspacecloud.com'
AUTH='{ "auth": { "RAX-KSKEY:apiKeyCredentials": { "username": "'${1}'", "apiKey": "'${2}'" } } }'
TOKENS=`echo ${AUTH} | http POST https://${ENDPOINT}/v2.0/tokens`
AUTHTOKEN=`echo ${TOKENS} | jq -r '.access.token.id'`
PUBLICURL=`echo ${TOKENS} | jq -r '.access.serviceCatalog[] | select(.name == "cloudFiles").endpoints[].publicURL'`

content_type=`echo ${line} | jq -r .content_type`
name=`echo ${line} | jq -r .name`
bytes=`echo ${line} | jq -r .bytes`
last_modified=`echo ${line} | jq -r .last_modified`
if [ ${name} != "index.html" ]
then
HTML+="\t\t\t<tr><td><a href=\"${name}\">${name}</a></td><td>${content_type}</td><td>${bytes}</td><td>${last_modified}</td></tr>\n"
fi
done < <( http GET ${PUBLICURL}/${3}?format=json X-Auth-Token:${AUTHTOKEN} | jq -c .[] )
HTML+="\t\t</table>\n"
HTML+="\t\t<div><br /><i>Generated on `date`</i></div>\n"
HTML+="\t</body>\n"
HTML+="</html>"
echo -e ${HTML} | http PUT ${PUBLICURL}/${3}/index.html X-Auth-Token:${AUTHTOKEN} Content-Type:text/html
Invoke the script using your cloud account username, the API-Key provided under your account details and the name of the container
$ ./cfindex.sh
Usage: ./cfindex.sh username apikey containername
Now just point your browser to your Cloud Files container URL to view a public list of all your files!
