temporarily removing the mysql volme (see issue here #18) i am able to get rs to start, but the applications aren't able to talk to each other via ssh.

CC gives me the following error after the 3 galera nodes come up:
libssh auth error: Access denied. Authentication that can continue: publickey,gssapi-keyex,gssapi-with-mic,password (root, key=/root/.ssh/id_rsa)

Inside the galara nodes, here is the contents of authorized_keys:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /keys/cc.pub was not found on this server.</p>
</body></html>

Here are the logs from a galera node:

AUTO_DEPLOYMENT is undefined. Using the default value: 1
CMON_PASSWORD is undefined. Using the default password: 
Linking exists. Using CC_HOST=10.51.250.78
