Addons
While Shulker has strong and well defined objectives to solve, Shulker is also present in every part of your Minecraft infrastructure: at the Kubernetes level of course, by administrating the different resources, but also in your proxies and servers thanks to the built-in agent plugins.
This makes Shulker capable of providing additional features that are not strictly required for your Minecraft cluster to operate, but are not easy to implement by yourself.
Shulker's addons are optional and opt-in components that can provide additional functionalities to your Minecraft clusters. They are not meant for everyone but for those who are interested in these specific features.
WARNING
It is important to note that Shulker is an infrastructure management tool before all. This means that some addons may need further work from you (deployment of required infrastructure, plugin development, etc...).
Providing a ready-to-use SDK will be preferred for you to manipulate addons allowing third-party manipulation, but will be not required.
