How to attach a resource to a charm at release time
You have a uploaded multiple updates to your resource, resulting in multiple revisions. This document shows you how you can now attach a specific one of them to a charm at release time, as a way to control the evolution of the charm and the resource it uses.
To attach a specific resource revision to a charm at release time, simply specify the resource revision, as in the example below:
$ charmcraft release my-super-charm --revision=13 --channel=stable --resource=someresource:2 Revision 13 of charm 'my-super-charm' released to stable (attaching resources: 'someresource' r2)
To inspect the results, ask for the charm status:
jdoe@machine:~/blogsystem$ charmcraft status my-super-charm Track Channel Version Revision Resources latest stable 7.4a 13 someresource (r1) candidate ↑ ↑ ↑ beta 7.4a 10 - edge ↑ ↑ -
If the charm needs a resource and it’s not indicated at release time it will be an error (unless that resource was already attached to the same charm in a previous release in that same channel, in which case Charmhub automatically will attach it in the new release).
