Limit client and upstream messages
Limit both client and upstream messages.
You can also use these settings to raise the default limits. Kong Gateway applies the following default limits to incoming messages for all WebSocket services:
- client:
1048576(1MiB) - upstream:
16777216(16MiB)
Add this section to your kong.yaml configuration file:
_format_version: "3.0"
plugins:
- name: websocket-size-limit
config:
client_max_payload: 4096
upstream_max_payload: 1048576
Make the following request:
curl -i -X POST http://localhost:8001/plugins/ \
--header "Accept: application/json" \

"config": {
"client_max_payload": 4096,
"upstream_max_payload": 1048576

Make the following request:
curl -X POST https://{region}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/plugins/ \

Make sure to replace the following placeholders with your own values:
-
region: Geographic region where your Kong Konnect is hosted and operates. -
KONNECT_TOKEN: Your Personal Access Token (PAT) associated with your Konnect account. -
controlPlaneId: Theidof the control plane.
