recently a change occurred in juju
v2.9.x which finally bit me today… while doing some local charm development work… I went to deploy a bundle which has reference to a local file path… this seems to no longer work if the node is already deployed … in past it simply trusted the charmed node was alright and to me moved on…
I am trying to figure out what is the expectation now, seems I need the yaml file to be in a certain path … and then any “downstream” charms to be in folders named after the yaml key entry… instead of the charm path?
series: focal applications: postgresql: charm: cs:postgresql num_units: 1 to: - "1" ibgateway: charm: /home/myuser/Dev/git/someproject/charms/inprogress-charm num_units: 1 to: - "2"
$ juju deploy ./config.yaml Located charm "postgresql" in charm-store, channel stable Executing changes: - upload charm inprogress-charm from local for series focal with architecture=amd64 ERROR cannot deploy bundle: cannot deploy local charm at "/home/myuser/Dev/git/someproject/charms/bundled-charm/inprogress-charm": file does not exist
I version control my bundles in seperate repos… so putting the charms directly in the path would require me to likely move the yaml file and possibly lose track of the version control without some … I guess symbolic links? not worried as I can just wipe that node and deploy without issue thereafter but… this will bite me during development later and I cannot understand the way forward
I see this language in the docs but… I think this needs to be clarified… I cannot really understand on it’s face what to do… so instead will need to just try some things out?
Using local charms
To integrate a local charm into a bundle a local bundle file, say bundle.yaml, will be needed and where the charm field points to the directory of the charm in question. Here is an example:
Relative paths are resolved relative to the path of the entity that describes them. That is, relative to the overlay bundle file itself.
Change in behaviour: Before Juju 2.7, relative paths within overlay bundles were resolved relative to the base bundle.
