# meta-operator
|
||||
|
||||
Meta operator enables creating operators without building any binaries or
|
||||
Docker images.
|
||||
|
||||
For example operator declaration see `keydb.yml`
|
||||
|
||||
```
|
||||
kubectl create namespace meta-operator
|
||||
kubectl apply -f application.yml -f keydb.yml
|
||||
```
