Also, any modifications that you make to you galaxy configuration (e.g., galaxy_tools.xml) become part of the shared instance. When a user then starts a new cluster and provides the cluster share string (this is available on the shared cluster after you share it), they will get access to an exact replica of your cluster. Like, I mentioned earlier, unless you are modifing system libraries there is absolutely no reason to create a new AMI. Simply contain your customizations to the file system and use cluster sharing functionality. Try it and see if it does what you need it to do. > > If you do indeed have a description of this somewhere that I just did not > find, then I am sorry but would be grateful for a link ;-) > > Sorry but there's no functionality about this feature on the wiki. However, there is a pretty detailed description of the functionality and the process on the cloudman console after you click the green share a cluster button. I'll work on preparing some additional documentation on this topic.
