Talking to Swift with Cyberduck
Note
Put together by Caleb Tennis, thanks Caleb!
Install Swift, or have credentials for an existing Swift installation. If you plan to install Swift on your own server, follow the general guidelines in the section following this one.
Verify you can connect using the standard Swift Tool st from your "public" URL (yes I know this resolves privately inside EC2):
ubuntu@domU-12-31-39-03-CD-06:/home/swift/swift/bin$ st -A https://ec2-184-72-156-130.compute-1.amazonaws.com:11000/v1.0 -U a3:b3 -K c3 stat Account: 06228ccf-6d0a-4395-889e-e971e8de8781 Containers: 0 Objects: 0 Bytes: 0
Note
The Swift Tool st can be copied from Swift sources to most any machine with Python installed. You can grab it from http://bazaar.launchpad.net/%7Ehudson-openstack/swift/trunk/annotate/head%3A/bin/st if you don't have the Swift code handy.
Download and extract the Cyberduck sources (3.5.1 as of this writing). They should be available at http://trac.cyberduck.ch/
Edit the Cyberduck source. Look for lib/cloudfiles.properties, and edit this file. Change auth_url to your public auth URL (note the https):
auth_url=https://ec2-184-72-156-130.compute-1.amazonaws.com:11000/v1.0
Edit source/ch/cyberduck/core/Protocol.java. Look for the line saying "storage.clouddrive.com". Just above that, change:
public boolean isHostnameConfigurable() { return true; }
In the root directory, run "make" to rebuild Cyberduck. When done, type: open build/Release/Cyberduck.app/ to start the program.
Go to "Open Connection", select Rackspace Cloud Files, and connect.
If you get SSL errors, make sure your auth and proxy server are both setup for SSL. If you get certificate errors (specifically, 'unable to find valid certification path to requested target'), you are using a self signed certificate, you need to perform a few more steps:
Note
For some folks, just telling the OS to trust the cert works fine, for others use the following steps.
As outlined here: http://blogs.sun.com/andreas/entry/no_more_unable_to_find, download http://blogs.sun.com/andreas/resource/InstallCert.java, run "javac InstallCert.java" to compile it, then run "java InstallCert https://your-auth-server-url:8080". This script will pull down that certificate and put it into a Java cert store, in your local directory. The file is jssecacerts.
You need to move that file to $JAVA_HOME/jre/lib/security, so your java run time picks it up.
Restart Cyberduck, and it should now allow you to use that certificate without an error.
Installing Swift For Use With Cyberduck
Both the proxy and auth servers will ultimately need to be running with SSL. You will need a key and certificate to do this, self signed is ok (but a little more work getting Cyberduck to accept it). Put these in /etc/swift/cert.crt and /etc/swift/cert.key.
Note
Creating a self-signed cert can usually be done with:
cd /etc/swift openssl req -new -x509 -nodes -out cert.crt -keyout cert.key
Example proxy-server config:
[proxy-server] bind_port = 8080 user = swift cert_file = /etc/swift/cert.crt key_file = /etc/swift/cert.key [auth-server] ssl = true
Example auth-server config:
[auth-server] default_cluster_url = https://ec2-184-72-156-130.compute-1.amazonaws.com:8080/v1 user = swift cert_file = /etc/swift/cert.crt key_file = /etc/swift/cert.key
Use swift-auth-create-account to create a new account:
ubuntu@domU-12-31-39-03-CD-06:/home/swift/swift/bin$ swift-auth-create-account a3 b3 c3 https://ec2-184-72-156-130.compute-1.amazonaws.com:8080/v1/06228ccf-6d0a-4395-889e-e971e8de8781
Note
It's important that the URL that is given back to you be accessible publicly. This URL is tied to this account, and will be served back to Cyberduck after authorization. If this URL gives back something like: http://127.0.0.1/v1/... this won't work, because Cyberduck will attempt to connect to 127.0.0.1.
This URL is specified in the auth-server config's default_cluster_url. However, once you have created an account/user, this URL is fixed and won't change even if you change that configuration item. You will have to use sqlite to manually edit the auth.db in order to change it (limitation of using the development auth server, but perhaps someone will patch in this ability someday).
Verify you can connect using the standard Swift Tool `st`:
ubuntu@domU-12-31-39-03-CD-06:/home/swift/swift/bin$ st -A https://127.0.0.1:11000/v1.0 -U a3:b3 -K c3 stat Account: 06228ccf-6d0a-4395-889e-e971e8de8781 Containers: 0 Objects: 0 Bytes: 0
