Enable MTLS authentication
Configure the plugin with a CA Certificate to enable mutual TLS authentication.
Prerequisites
- You have created a CA Certificate and retrieved its ID.
Environment variables
-
CA_CERTIFICATE_ID: The ID of the CA Certificate to use.
Add this section to your declarative configuration file:
_format_version: "3.0"
plugins:
- name: mtls-auth
config:
ca_certificates:
- ${{ env "DECK_CA_CERTIFICATE_ID" }}
Make the following request:
curl -i -X POST http://localhost:8001/plugins/ \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data '
{
"name": "mtls-auth",
"config": {
"ca_certificates": [
"'$CA_CERTIFICATE_ID'"
]
}
}
'
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 $KONNECT_TOKEN" \
--data '
{
"name": "mtls-auth",
"config": {
"ca_certificates": [
"'$CA_CERTIFICATE_ID'"
]
}
}
'
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.
See the Konnect API reference to learn about region-specific URLs and personal access tokens.
