CustomResourceDefinitions
A core feature of the EMQX Operator is to monitor the Kubernetes API server for changes to specific objects and ensure that the running EMQX deployments match these objects. The Operator acts on the following custom resource definitions (CRDs).
For more details on EMQX, please check the reference document.
The EMQX Operator automatically detects changes on any of the above custom resource objects and ensures that running deployments are kept in sync with the changes.
