I am a software engineer in eBay, working on > Hadoop as a Service on top of Openstack cloud. > > Right now we are using Sahara, Juno version. We want to stay current and > introduce global template into sahara. > > In order to simplify the cluster creation process for user, we would > like to create some cluster templates available for all users. User can > just go to the horizon webUI, select one of the pre-popluated templates and > create a hadoop cluster, in just a few clicks. > > Here is how I would implement this feature: > > - In the database, Create a new column in “cluster_templates" table > called “is_global”, which is a boolean value indicating whether the > template is available for all users or not. > - When user getting the cluster template from database, add another > function similar to “cluster_template_get”, which query the database for > global templates. > - When creating cluster, put the user’s tenant id in > the “merged_values” config variable, instead of the tenant id from cluster > template. > - Use an admin account create and manage global cluster templates > > Since I don’t know the code base as well as you do, what do you think > about the global template idea? How would you implement this new feature? > > We would like to contribute this feature back to the Openstack > community. Any feedback would be greatly appreciated.
