Note Based on the end-of-life announcement from the Fedora CoreOS community, updates are no longer provided for CoreOS Container Linux as of May 26, 2020. In light of this, Alibaba Cloud has issued the following announcements:- As of May 26, 2020, Alibaba Cloud no longer provides technical support for ECS instances that use the CoreOS Container Linux operating system. However, you can still use existing ECS instances that run this operating system.
- You can still obtain CoreOS Container Linux images from Alibaba Cloud before September 30, 2020. After September 30, 2020, you will be unable to use CoreOS Container Linux public images provided by Alibaba Cloud to create ECS instances.
- As of May 26, 2020, CoreOS Container Linux can continue to be used on instances on which it is already installed. However, no security patches are available because the operating system has reached its end of life. For security concerns, we recommend that you no longer use CoreOS Container Linux images.
- The Fedora CoreOS community recommends that you use Fedora CoreOS in place of CoreOS Container Linux. Alibaba Cloud will bring Fedora CoreOS public images online soon.
