envoy gateway gatewayClass

 

Envoy gateway supports one GatewayClass (one load balancer per K8s) but sometimes there could be more scenario where you have more than one GatewayClass - 2 or more load balancer) then you might need to instantiate that in a namespace. 

Troubleshooting gateway issues

kubectl get gatewayclass 

If your gatewayclass works correctly, then its column "Accepted" would be true - as shown below. My Product gatewayClass has issue as it has a status "Unknown".



Also you can do a kubectl logs on the envoy proxy controller in the envoy-gateway-system. It should shows a huge bunch of logs about reconciling gateway classes. 

In my scenario, I have multiple gateway class.

If you do a kubectl get gateway  -A, you should see PROGRAMMED = true if your gateway is running correctly. 

Since I created another gateway class in marketing namespace, it also create a Load Balancer service and if you look at the diagram above, i have it bind to localhost:8080.  So all I need to do is to hit  the following url 

curl --verbose --header "Host: www.marketing.example.com" http://localhost:8080/get

The specified initialization vector (IV) does not match the block size for this algorithm

If you're getting  exception when trying to assigned key to a symmetric key and getting error message below :- The specified initialization vector (IV) does not match the block size for this algorithm And your code probably look like something below :- Then you need to go into debug mode and start looking into the supported size for IV as shown in diagram below :- As you can see, IV is 16 bytes, so you need to provide 16 bytes. The same goes for Key field too, if you're adding anything to it. As long as you provide a valid key size, then we're good and you're code will be ready.
