Spinnaker is a really interesting piece of kit, though when I last tried it 3-4 months ago the docs were in a state of flux and it took quite a lot of fiddling about to get things going.<p>The one thing I cannot find any details on, and it's not specific to Spinnaker, is; how do you perform your database changes as part of your deployment system? I figured it would be sensible to have one-off tasks you could run inside your containers as part of the pipelines, but I've not found any guidance on doing that with any CD tool at the moment.
