Basic configuration examples

The following examples provide some typical configurations for enabling the canary plugin on a service.

Make the following request:

curl -X POST http://localhost:8001/services/{serviceName|Id}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
  "name": "canary",
  "config": {
    "percentage": 50,
    "upstream_host": "example.com",
    "upstream_port": 80
  }
}
    '

Replace SERVICE_NAME|ID with the id or name of the service that this plugin configuration will target.

Make the following request, substituting your own access token, region, control plane ID, and service ID:

curl -X POST \
https://{us|eu}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/services/{serviceId}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer TOKEN" \
    --data '{"name":"canary","config":{"percentage":50,"upstream_host":"example.com","upstream_port":80}}'

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

Add this section to your declarative configuration file:

plugins:
- name: canary
  service: SERVICE_NAME|ID
  config:
    percentage: 50
    upstream_host: example.com
    upstream_port: 80

Replace SERVICE_NAME|ID with the id or name of the service that this plugin configuration will target.

Prerequisite: Configure your Personal Access Token 
terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_canary" "my_canary" {
  enabled = true

  config = {
    percentage = 50
    upstream_host = "example.com"
    upstream_port = 80
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
  service = {
    id = konnect_gateway_service.my_service.id
  }
}

The following examples provide some typical configurations for enabling the canary plugin on a route.

Make the following request:

curl -X POST http://localhost:8001/routes/{routeName|Id}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
  "name": "canary",
  "config": {
    "percentage": 50,
    "upstream_host": "example.com",
    "upstream_port": 80
  }
}
    '

Replace ROUTE_NAME|ID with the id or name of the route that this plugin configuration will target.

Make the following request, substituting your own access token, region, control plane ID, and route ID:

curl -X POST \
https://{us|eu}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/routes/{routeId}/plugins \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer TOKEN" \
    --data '{"name":"canary","config":{"percentage":50,"upstream_host":"example.com","upstream_port":80}}'

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

Add this section to your declarative configuration file:

plugins:
- name: canary
  route: ROUTE_NAME|ID
  config:
    percentage: 50
    upstream_host: example.com
    upstream_port: 80

Replace ROUTE_NAME|ID with the id or name of the route that this plugin configuration will target.

Prerequisite: Configure your Personal Access Token 
terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_canary" "my_canary" {
  enabled = true

  config = {
    percentage = 50
    upstream_host = "example.com"
    upstream_port = 80
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
  route = {
    id = konnect_gateway_route.my_route.id
  }
}

A plugin which is not associated to any service, route, consumer, or consumer group is considered global, and will be run on every request.

  • In self-managed Kong Gateway Enterprise, the plugin applies to every entity in a given workspace.
  • In self-managed Kong Gateway (OSS), the plugin applies to your entire environment.
  • In Konnect, the plugin applies to every entity in a given control plane.

Read the Plugin Reference and the Plugin Precedence sections for more information.

The following examples provide some typical configurations for enabling the Canary Release plugin globally.

Make the following request:

curl -X POST http://localhost:8001/plugins/ \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --data '
    {
  "name": "canary",
  "config": {
    "percentage": 50,
    "upstream_host": "example.com",
    "upstream_port": 80
  }
}
    '

Make the following request, substituting your own access token, region, and control plane ID:

curl -X POST \
https://{us|eu}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/plugins/ \
    --header "accept: application/json" \
    --header "Content-Type: application/json" \
    --header "Authorization: Bearer TOKEN" \
    --data '{"name":"canary","config":{"percentage":50,"upstream_host":"example.com","upstream_port":80}}'

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

Add a plugins entry in the declarative configuration file:

plugins:
- name: canary
  config:
    percentage: 50
    upstream_host: example.com
    upstream_port: 80
Prerequisite: Configure your Personal Access Token 
terraform {
  required_providers {
    konnect = {
      source  = "kong/konnect"
    }
  }
}

provider "konnect" {
  personal_access_token = "kpat_YOUR_TOKEN"
  server_url            = "https://us.api.konghq.com/"
}

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:

resource "konnect_gateway_plugin_canary" "my_canary" {
  enabled = true

  config = {
    percentage = 50
    upstream_host = "example.com"
    upstream_port = 80
  }

  control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
}
