Custom plugins in Dedicated Cloud Gateways

With Dedicated Cloud Gateways, Konnect can stream custom plugins from the control plane to the data plane.

This means that the control plane becomes a single source of truth for plugin versions. You only need to upload a plugin once, to the control plane, and Konnect handles distributing the plugin code to all data planes in that control plane.

Compared to the manual process required in a regular hybrid Konnect deployment, custom plugin streaming in Dedicated Cloud Gateways provides the following benefits:

  • Faster custom plugin distribution
  • Minimal manual maintenance
  • The control plane is the single source of truth

Prerequisites

  • Your custom plugin meets the following requirements:
    • Each custom plugin must have a unique name.
    • Each custom plugin can have a maximum of 1 handler.lua file and 1 schema.lua file.
    • The plugin can’t execute in the init_worker phase and can’t set any timers.
    • The plugin must be written in Lua. No other languages are supported.
  • You have a personal access token or system access token for the Konnect API

Adding a custom plugin to a Dedicated Cloud Gateway deployment

Upload custom plugin schema and handler files to create a configurable entity in Konnect. If you prefer using the Konnect UI, you can also upload these files through the Plugins menu in Gateway Manager.

The name you give the plugin must be identical to the name of the plugin in the schema file.

Using the following command, make a POST request to the /custom-plugins endpoint of the Konnect Control Plane Config API:

curl -X POST https://{region}.api.konghq.com/v2/control-planes/{control-plane-id}/core-entities/custom-plugins \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer {your-access-token}" \
  -d "$(jq -n \
      --arg handler "$(cat handler.lua)" \
      --arg schema "$(cat schema.lua)" \
      '{"handler":$handler,"name":"streaming-headers","schema":$schema}')" \
    | jq

This request returns an HTTP 200 response with the schema and handler for your plugin as a JSON object.

Once a custom plugin is uploaded to a Dedicated Cloud Gateway control plane, it can be managed like any other plugin, using any of the following tools:
