kubernetes 使用的 cni 插件会因此受影响(cni并不会在 FORWARD 链中生成相应规则),由此导致除 pod 所在 host 以外节点无法转发报文而访问失败。 解决办法: 如果对安全要求较低,可将 FORWARD 链的默认规则设为 ACCEPT iptables -PFORWARD ACCEPT google 网络不可达 https://packages.cloud.google.com/yum/repos/kub...
While it is not necessary to use Kubernetes to manage a Docker deployment, they are an effective tandem in situations where multiple instances of deployments must be managed.

Ensure consistent application performance across any environment, whether it’s on-premises Kubernetes or cloud platforms like AWS ECS, Azure ACI, and Google GKE. Optimize builds with Docker Build Cloud Explore allChoose plan Why use Docker?
In this article I will give a high level overview of how we have set up our servers with help of Kubernetes and Docker and why we have chosen such a combination.
Based on the above requirements, Kubernetes has the concept of Pod to handle this close relationship. Containers in a Pod share the same Cgroups and Namespace, so there is no boundary and isolation environment between them. They can share the same network IP, use the same Volume to process ...
