ALB Ingress Controller

Application Load Balancer (ALB) Ingress Controller uses Yandex Application Load Balancer for load balancing and traffic distribution across Kubernetes applications.

In Managed Service for Kubernetes, the ALB Ingress Controller runs Yandex Application Load Balancer and the necessary supporting resources whenever a Kubernetes user declares an Ingress resource in the cluster.

1. Install kubectl and configure it to work with your cluster.

2. For streaming JSON files, install jq:

   sudo apt update && sudo apt install jq
   

3. Create a service account to run the Ingress controller.

4. Assign it the following roles:

   • alb.editor: To create the required resources.
   • vpc.publicAdmin: To manage external connectivity.
   • certificate-manager.certificates.downloader: To use certificates registered in Yandex Certificate Manager.
   • compute.viewer: To use Managed Service for Kubernetes cluster nodes in the load balancer target groups.

5. Create a static key for the service account and save it to a file named sa-key.json:

   yc iam key create \
     --service-account-name <name of the Ingress controller service account> \
     --output sa-key.json
   

6. Configure the application:

   • Namespace: Select a namespace or create a new one.
   • Application name: Enter the name of the application.
   • Folder ID: Specify the folder ID.
   • Cluster ID: Specify the cluster ID.
   • Service account key: Paste the contents of the sa-key.json file.

7. Click Install.
