Deploy a self-hosted gateway to Kubernetes with YAML

  • Članek

APPLIES TO: Developer | Premium

This article describes the steps for deploying the self-hosted gateway component of Azure API Management to a Kubernetes cluster.

Opomba

You can also deploy self-hosted gateway to an Azure Arc-enabled Kubernetes cluster as a cluster extension.

Prerequisites

Deploy to Kubernetes

Nasvet

The following steps deploy the self-hosted gateway to Kubernetes and enable authentication to the API Management instance by using a gateway access token (authentication key). You can also deploy the self-hosted gateway to Kubernetes and enable authentication to the API Management instance by using Microsoft Entra ID.

  1. Select Gateways under Deployment and infrastructure.
  2. Select the self-hosted gateway resource that you want to deploy.
  3. Select Deployment.
  4. An access token in the Token text box was auto-generated for you, based on the default Expiry and Secret key values. If needed, choose values in either or both controls to generate a new token.
  5. Select the Kubernetes tab under Deployment scripts.
  6. Select the <gateway-name>.yml file link and download the YAML file.
  7. Select the copy icon at the lower-right corner of the Deploy text box to save the kubectl commands to the clipboard.
  8. When using Azure Kubernetes Service (AKS), run az aks get-credentials --resource-group <resource-group-name> --name <resource-name> --admin in a new terminal session.
  9. Run the commands to create the necessary Kubernetes objects in the default namespace and start self-hosted gateway pods from the container image downloaded from the Microsoft Artifact Registry.
    • The first step creates a Kubernetes secret that contains the access token generated in step 4. Next, it creates a Kubernetes deployment for the self-hosted gateway which uses a ConfigMap with the configuration of the gateway.

Confirm that the gateway is running

  1. Run the following command to check if the deployment succeeded. It might take a little time for all the objects to be created and for the pods to initialize.

    Console 
    kubectl get deployments

    It should return

    Console 
    NAME             READY   UP-TO-DATE   AVAILABLE   AGE
<gateway-name>   1/1     1            1           18s

  2. Run the following command to check if the services were successfully created. Your service IPs and ports will be different.

    Console 
    kubectl get services

    It should return

    Console 
    NAME                                TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                      AGE
<gateway-name>-live-traffic         ClusterIP      None            <none>        4290/UDP,4291/UDP   9m1s
<gateway-name>-instance-discovery   LoadBalancer   10.99.236.168   <pending>     80:31620/TCP,443:30456/TCP   9m1s

  3. Go back to the Azure portal and select Overview.

  4. Confirm that Status shows a green check mark, followed by a node count that matches the number of replicas specified in the YAML file. This status means the deployed self-hosted gateway pods are successfully communicating with the API Management service and have a regular "heartbeat."

  • Run the kubectl logs deployment/<gateway-name> command to view logs from a randomly selected pod if there's more than one.
  • Run kubectl logs -h for a complete set of command options, such as how to view logs for a specific pod or container.
