Custom OPA host and portv2.4+
Configure the OPA plugin to connect to an OPA server with a custom host and port and get the /my_policies/header policy.
Prerequisites
- OPA server running
Environment variables
-
OPA_HOST: The host of your OPA server.
Add this section to your kong.yaml configuration file:
_format_version: "3.0"
plugins:
- name: opa
config:
opa_host: ${{ env "DECK_OPA_HOST" }}
opa_port: 8182
opa_path: "/v1/data/my_policies/header"
Make the following request:
curl -i -X POST http://localhost:8001/plugins/ \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data '
{
"name": "opa",
"config": {
"opa_host": "'$OPA_HOST'",
"opa_port": 8182,
"opa_path": "/v1/data/my_policies/header"
}
}
'
Make the following request:
curl -X POST https://{region}.api.konghq.com/v2/control-planes/{controlPlaneId}/core-entities/plugins/ \
--header "accept: application/json" \
--header "Content-Type: application/json" \
--header "Authorization: Bearer $KONNECT_TOKEN" \
--data '
{
"name": "opa",
"config": {
"opa_host": "'$OPA_HOST'",
"opa_port": 8182,
"opa_path": "/v1/data/my_policies/header"
}
}

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