Use Elastic Container Instance in ASK clusters

Last Updated: Sep 08, 2021

This topic describes how to use Elastic Container Instance in Serverless Kubernetes (ASK) clusters. ASK is integrated with a variety of Alibaba Cloud services, including Elastic Container Instance. You can create an ASK cluster deployed on Elastic Container Instance in a fast and simple manner.

Introduction to ASK

ASK is a serverless solution for Kubernetes containers that is provided by Alibaba Cloud on top of the elastic compute architecture. ASK allows you to deploy containerized applications without the need to purchase, manage, or plan nodes. You are charged only for the amount of CPU and memory resources that you allocate for your applications.

ASK is fully compatible with Kubernetes. You can use ASK API or command lines to manage containerized applications. ASK is also integrated with Alibaba Cloud services to help you simplify development on Kubernetes and focus on your applications instead of managing underlying resources.

In ASK clusters, you can create pods without manually deploying virtual nodes. Pods in ASK clusters run in a secure and isolated container runtime environment that is built on an elastic container instance. Each pod runs on a dedicated elastic container instance, as shown in the following figure.ASK

For more information, see ASK overview.

Procedure

You can create an ASK cluster in the ACK console and deploy applications in the cluster.

Note

Each pod that is created in an ASK cluster runs on a dedicated elastic container instance. You can view information about each pod in the Elastic Container Instance console. To use Elastic Container Instance features when you create a pod, you can add annotations. For more information, see Pod annotations supported by Elastic Container Instance.

For the procedure about using Elastic Container Instance in ASK clusters, see the following topics:

  1. Create an ASK cluster

  2. Create an application from an image

  3. Create a Service

  4. View pods
