Updated features of and release notes for aliyun-acr-acceleration-suite - Container Service for Kubernetes

This topic describes the updated features of and release notes for aliyun-acr-acceleration-suite.

Overview

aliyun-acr-acceleration-suite is a client plug-in that enables on-demand image loading and accelerates image loading. You can deploy this component on a worker node as a DaemonSet. Container Service for Kubernetes (ACK) collaborates with Container Registry to enable accelerated images. After you deploy aliyun-acr-acceleration-suite in a cluster, the system automatically converts a source image into an accelerated image. When an image pull request is received, the system decompresses data based on your business requirements without interrupting services. In this case, the system does not have to download or decompress full data. This accelerates application deployment and enables on-demand image loading.

Note

Only ACK managed and ACK dedicated clusters that run Kubernetes 1.16.9 or later support accelerated images. When you create a cluster, you must specify Alibaba Cloud Linux 3.2104, Alibaba Cloud Linux 2.1903, or CentOS 7.9 as the operating system of the cluster.

No impact on workloads

June 2022

Version	Image address	Release date	Description	Impact
0.2.2	registry-vpc.cn-hangzhou.aliyuncs.com/acr-toolkit/aliyun-acr-acceleration-suite:v0.2.0.0-b01f3302-aliyun	2022-06-08	The issue that ACK clusters that run Kubernetes 1.22 failed to synchronize the secrets that are used to pull images is fixed. The update operation is no longer supported by mutating webhooks. This prevents unexpected actions. The stability of aliyun-acr-acceleration-suite is improved. The `requests and limits` parameters are added to the configurations of the pods that are provisioned for aliyun-acr-acceleration-suite. The timeout period of webhooks is changed to 5 seconds. The time-to-live (TTL) for the webhook cache is changed to 60 seconds.	No impact on workloads

March 2021
