Customize Kubenretes Ingress

Customizing Ingress rules for exchanges on Kubernetes
Once you run HollaEx CLI commands with --kube flag, HollaEx CLI would automatically generate Ingress rules for Kubernetes with default form. You can check these generated templates under templates/kubernetes/<EXCHANGE_NAME>-ingress.yaml> .
Default Ingress should be similar to the examples down below.
HollaEx CLI generates Ingress rules which compatible with kubernetes/nginx-ingress.If you are planning to use a different Ingress controller, please customize annotations and detailed values based on your own ones.
Nginx rate limit setups on nginx.ingress.kubernetes.io/configuration-snippet are following pre-defined rate limit zone setups on bitHolla's own Ingress controller. 
api : 4r/s
Please reference these values and add it on your own Ingress controller. For example, kubernetes/nginx-ingress support annotation called http-snippet to let user inject code snippets on Nginx.conf.

For example, if you are planning to use nginxinc/kubernetes-ingress, certain annotations should be modified as shown below.
If you are planning to use splitted Ingress rules like the example up above, Consider using nginx.org/mergeable-ingress-type.
nginx.ingress.kubernetes.io/proxy-body-size-> nginx.org/client-max-body-size
nginx.ingress.kubernetes.io/configuration-snippet -> nginx.org/location-snippets
