How to install custum hostallocator module

[hacked473]

Hi
I developed a custom host allocator and created a jar file. I read cloudstack document about how to install it, but the explanation was about changing tomcat configurations. As I know cloudstack does not use tomcat anymore. please guide me how to enable this allocator
module and use it on cloudtsack 4.19 .

thanks

@hacked473 If you've developed your custom host allocator as an adapter similar to FirstFitAllocator, you're on the right track. You can refer to that class and how it's registered and used in the CloudStack codebase.

If you are having a development environment, you will need to follow below steps,

1. Build the project and get client/target/cloud-client-ui-4.19.3.0-SNAPSHOT.jar this ready with your changes
2. Copy it in your management server under location /usr/share/cloudstack-management/lib with the name cloudstack-4.19.3.0.jar (Correct the names as per the version you are using and developing)
3. In the management server UI, set the global setting "host.allocators.order" with your custom host allocator name.
4. Restart the management server.
