Is there a way to be notified of an on-going update ?
In a multi-container context, I would like for our browser web-app display a message indicating that we are upgrading and that our service is currently unavailable. Of course, if the browser is also updated, we can’t do that, but we plan to pin the browser sha256 image version to avoid unnecessary updates.
I’d like to execute a script/whatever when the updates begin. This script will emit a message on our local RabbitMQ instance. Do you know if that’s possible ?
I assume its an app update. I am not sure if we can pin a release for one of the container. But depending on the behavior from an update, we could also look at communication between containers to relay this information.
We tried this solution which worked fine regarding our requirements for updates displaying, however it locks the supervisor which prevent a lot of actions to be done: rebooting, stopping services, etc.
I can’t believe we are the only ones wanting to display an “Update in progress” message to our users… how are we supposed to do this ?
