Proxy protocol on VerneMQ kubernetes operator.

[Eduardo Hering]

Hi.

I successfully managed to install an HAProxy Ingress Controller and a VerneMQ kubernetes operator on the same k8s cluster. Both were configured to use proxy-protocol-v2. But when I ask vmc-admin to show sessions it shows only reserved IPs:

|        69:02:b8:50:6d:c8        |  true   |          |10.240.0.4 |  4256   |xxxx |

|        69:02:b8:71:eb:f4        |  true   |          |10.240.0.4 |  23573  |xxxx |

|        69:02:b8:63:bc:34        |  true   |          |10.240.0.6 |  24889  |xxxx |

|        69:02:b8:71:ee:c7        |  true   |          |10.240.0.6 |  25818  |xxxx |

|        69:02:b8:5b:7c:1f        |  true   |          |10.240.0.6 |  60822  |xxxx |

|        69:02:b8:5f:31:64        |  true   |          |10.240.0.4 |  3215   |xxxx |

|        69:02:b8:5c:60:a9        |  true   |          |10.240.0.5 |  37592  |xxxx |

+---------------------------------+---------+----------+-----------+---------+----+

My vernemq-vernemq.yaml file has the following definitions:

...

 listeners:

- address: 0.0.0.0
port: 1883
maxConnections: 10000
nrOfAcceptors: 10
proxyProtocol: true

...

I am able to connect to the cluster from outside using TLS terminated on HAProxy.

Can somebody please help?

Hi Eduardo,

I can't really help with Kubernetes networking, but I'm curious what's happening here.

Clearly, there are multiple MQTT sessions coming from the same IPs, so the first question I guess is what those IPs are. Is this from a load test you run?

Best,

André
