Karaf Minho
Hi,
I've looked at the githib repo (https://github.com/jbonofre/karaf5) at
Minho.
It looks very interesting to me, as I want to host multiple Spring Boot
applications into one container.
A few questions:
- I read there is an example of two Spring Boot applications that can run
into Minho, but I can not find the example. Can you tell me where the
example is?
- Does Minho support dynamic loading of Spring Boot application?
Best,

Hi Jaap,
We are working on the examples (we are planning several examples,
including multi spring boot apps in minho, I'm working on minho k8s
controller example, etc).
We are working on it.
Right now, the loading approach is static (at bootstrap), but if we
have user request to support dynamic loading, why not. Feel free to
create a GitHub issue once you test it.
Regards
JB

Oh by the way, Minho moved to Apache Karaf umbrella now:

Hi Matt,
Thanks for your anser.
For us, it is interesting to understand of Minho supports ddynamic
loading/unloading.
It supports Spring Boto we currently use.
I think we can narrow down our choice whether to follow the Minho path (with
Spring Boot and dynamic (un)loading) or to start all over in Karaf/OSGI.
Best,

Hi Jaap-
There does not need to be only one Karaf instance. A well designed modular application can have co-located services or remote services. Karaf gives you the option to have everything all-in-one for development and then split things out (frontend, backend and/or service apis) at deployment time as needed.
Thanks,

- Spring Cloud: usually small balls of mud interacting, no crash barriers build in for designing a clean modular and loosely coupled architecture
- Apache Karaf: OSGi providing the crash barriers to guide developers in making the right choices creating modules by separation of concerns and communicating over a central OSGi service registry, needs more than average knowledge of the Java classpath, module dependencies and SOLID in general
-Apache Karaf Minho: what I know sofar, by default a single classpath and no OSGi livecycle (which could limit dynamic loading of new code?), service propagation done by the Java 6 default service provider mechanism

Essentially, to build a dynamic frontend/backend plugin system we have to decide to go for:
- Spring Cloud (large community, but needs many processes / JVMs to build it , so it seems not very efficient
- Apache Karaf (efficient system as there needs only to be one JVM, but
complex)
- Minho, which seems to be able to dynamically (un)load Spring Boot modules)

Hi,
We need to go a little deeper with springboot, we have already noted
this point here:

Essentially, to build a dynamic frontend/backend plugin system we have to
decide to go for:
- Spring Cloud (large community, but needs many processes / JVMs to build it
, so it seems not very efficient
- Apache Karaf (efficient system as there needs only to be one JVM, but
complex)
- Minho, which seems to be able to dynamically (un)load Spring Boot modules)
