Partial deployment of application from a module without updating the services

[stevschm]

Hi,
we've got a module which requires a lot of resources/services, that don't change.
If I make a partial deployment via "cf deploy -m <module_name>" then all resources also get's processed/updated.
Is it possible to just "update" one application/module without updating all the resources/services?

Thanks,
Steve

Hi,

We've tracked this problem and it should be fixed soon since currently if no module/resource is specified all of the modules/resources will be updated. You can specify the resources that you need to update via "-r" option and this way only the provided resources will be updated.

Thanks and best regards,
Ivan

Hi @IvanBorislavovDimitrov Can you concretise "should be fixed soon" a bit? I still see the same behaviour with the latest plugin version 2.7.0. We also would prefer the requested behaviour that if we specify -m it will ignore all resources unless we also add -r.

Options:

1. cf deploy <MTA>: updates all modules and all resources (This already works)
2. cf deploy <MTA> -m <module A>: Just updates module A and no resources
3. cf deploy <MTA> -r <resource X>: Just updates resource X and no modules
4. cf deploy <MTA> -m <module A> -r <resource X>: Updates module A and resource X (This already works)

Assuming you have a lot of resources, and you really want to update all of them but just update a single module, we already have the flag --all-resources.

We could also keep updating all resources on default and add a new flag --skip-resources.

I don't mind too much about which way, but the cf deploy should become a bit more flexible.
Thanks and best regards, Tom

Is this plugin still supported? Not so much activity lately.

Hi,
The plugin is supported as well as its "counterpart" MultiApps Controller which serves as a backend and performs the actual business logic.
Note that the plugin itself is pretty stable and the larger part of the feedback/issues are actually directed to the backend MultiApps Controller. On the other side the plugin represent simple client to the backend.

I would suggest a workaround which will tells the MultiApps Controller to skip the service updates via the parameter called skip-service-updates. Check: https://github.com/SAP-samples/cf-mta-examples/blob/main/skip-service-updates/mta.yaml#L12

@Kiemes I can see that you are part of SAP so I will send the internal backlog item and you can subscribe to it.
