plugins:
- name: kong-spec-expose
config:
spec_url: ${{ env "DECK_SPEC_URL" }}
Make the following request:
curl -i -X POST http://localhost:8001/plugins/ \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data '
{
"name": "kong-spec-expose",
"config": {
"spec_url": "'$SPEC_URL'"
}
}

}
}
provider "konnect" {

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:
resource "konnect_gateway_plugin_kong_spec_expose" "my_kong_spec_expose" {
enabled = true
config = {
spec_url = var.spec_url
}
control_plane_id = konnect_gateway_control_plane.my_konnect_cp.id
}
This example requires the following variables to be added to your manifest. You can specify values at runtime by setting TF_VAR_name=value
.
variable "spec_url" {
type = string
}
Add this section to your declarative configuration file:
_format_version: "3.0"
plugins:
- name: kong-spec-expose
service: serviceName|Id
config:
spec_url: ${{ env "DECK_SPEC_URL" }}
Make sure to replace the following placeholders with your own values:
-
serviceName|Id
: Theid
orname
of the service the plugin configuration will target.
Make the following request:
curl -i -X POST http://localhost:8001/services/{serviceName|Id}/plugins/ \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data '
