Hi,

Please let me know, Is it possible to update the application alone using mender.
In our case, the application will always be running and we need to update the application using mender.
Instead of updateing the whole rootfs just wanted to update the application alone which is running in the active rootfs.
If this application update is possible, please let us know, How to do it and also reference link or document to do so.

Thank you,

I believe that’s what the update-modules mechanism is designed for

Indeed Update Modules are intended for just this use case. The exact mechanics will depend on how you plan to package your application. ie Is it a single binary file, a deb package, a docker container or some other.

If you can provide a bit more detail regarding your setup we may be able to guide you further.
