Industry news reveals the first Kubernetes SIG-Cloud-Provider sub-project in China.

As a staunch promoter of cloud native computing, Aliyun contributed the best open source component running Kubernetes on Aliyun, becoming the first domestic cloud vendor of the SIG Cloud Provider sub-project. At 10:00 on February 12, 2020, Aliyun's Kubernetes team held its first online webinar.

What technology made Ali win the National technological Invention Award?

At the beginning of the new year, the National Science and Technology Award Conference was solemnly held in the Great Hall of the people in Beijing. Ali Yun won two national awards: the National technological Invention Award and the National Science and Technology Progress Award. This is the first time that an Internet company has won two major national science and technology awards at the same time, and it has also achieved a zero breakthrough in the National Technology Invention Award.

IstioIstio introduces EGDS to support incremental push of Endpoint

Istio and Envoy began to introduce a new xDS resource type, EGDS (Endpoint Group Discovery Service), to support dynamic updates of Endpoint through EGDS. EDS can include any EGDS resource, and each EGDS contains a certain number of Endpoint. The background for the introduction of EGDS is that when the Cluster is very large, such as having 10000 Endpoint, even a small number of Endpoint changes will lead to a complete EDS push. Incremental push of Endpoint needs to be considered for promotion.

Istio adds Virtual Service chaining function

The VirtualService chain is an improvement on the Istio VirtualService specification that allows the routing configuration of mesh to be specified in multiple composable VirtualService resources that can be linked together to create advanced traffic routing capabilities in a user-friendly manner. Composable VirtualService resources allow organizations with multiple teams to maintain ownership of routing resources for the services they create, and allow operators to manage routing at the Gateway and Ingress levels to allow traffic to enter the Mesh and direct to appropriate back-end service routing resources.

Kube-storage-version-migrator is recommended for open source projects

You can migrate the old version of ApiVersion from the resources in the cluster to the new version.

Kubepug

Kubepug is a kubectl plug-in that scans the cluster before upgrading, and warns if there are resources in the cluster that have been abandoned or deleted in the target version.

Kind

Kind is a software that can be used in docker, and we can test it through the local K8s cluster.
