Hi Thomas, What I've found helpful is the ability to amend or override the set of modules contained in a modular runtime image via --module-path and --upgrade-module-path.
If you use (Docker) containers to deploy your app, this can be employed nicely to separate images with your app's dependencies (as a modular runtime image) and a very thin image with your app itself. Unless your dependencies change, only the latter one needs to be re-built and distributed. The "exclude-resources" plug-in comes in handy for omitting your app from the modular runtime image. I've written about it here: https://github.com/moditect/moditect/wiki/Creating-dependency-images. --Gunnar 2018-01-07 18:23 GMT+01:00 Thomas Brand <t...@trellis.ch>: > On Sun, December 31, 2017 17:13, Remi Forax wrote: > > jlink is not a distribution tool, you need to use a tool on top of jlink, > > in the past, i've used the rpm format for that. > > > > We have stopped to distribute deltas when we have moved to docker that as > > far as i know as no concept of incremental update. > > > > Rémi > > > > > > ----- Mail original ----- > > > >> De: "Alan Bateman" <alan.bate...@oracle.com> > >> À: "Thomas Brand" <t...@trellis.ch>, "jigsaw-dev" > >> <jigsaw-dev@openjdk.java.net> > >> Envoyé: Dimanche 31 Décembre 2017 16:55:37 > >> Objet: Re: Update a runtime image > >> > > > >> On 31/12/2017 15:42, Thomas Brand wrote: > >> > >>> Hello, I have a question related to jlink. > >>> > >>> > >>> In a scenario where a runnable image created with jlink is installed, > >>> and it should be updated, what are good strategies for doing this? > >>> > >>> I think if an update will introduce new dependencies this will be > >>> different to updates that are known to be satisfied with what is > >>> already in the image. > >>> > >>> The idea is to 'ship' just a small sort of diff / replacement part > >>> that can be applied to the 'old' image to become 'new'. > >>> > >> The jlink tool always generates a new run-time image, there is no > >> support at this time to install additional modules into a run-time > >> image. > >> > >> -Alan. > >> > > Thanks for the facts & suggestions! > Greetings > > > > >
