A namespace is a collection of resources and objects. Multiple namespaces can be created inside a cluster and isolated from each other. This enables namespaces to share t
This API is used to create a namespace.Currently, CCI provides two types of resources: general-computing resources and GPU-accelerated resources. When creating a namespac

5. Restrict Namespace One of the original requirements of this exercise is to watch for pod creation events in a specific namespace. By default, operators watch for events in all namespaces. Fortunately, it’s trivial to restrict the namespace that your operator watches. In main.go, find wh...
CentOS的selinux是关闭的,而docker上的selinux却是开启的,因此docker运行时会产生如上错误。 解决方案无非是要么都关闭,要么都开启。参看https://github.com/coreos/bugs/issues/2340, 推荐修改crntOS下的/etc/selinux/config 将SELINUX=disabled 改成 SELINUX=permissive,至少腾讯云的CoreOs就是这样子的。
In this tutorial, we created a highly efficient and cost-effective Kubernetes cluster on the Scaleway cloud platform. We started by laying the foundation, setting up an IPv6-only infrastructure, replacing the traditional kube-proxy with Cilium for enhanced security and performance. ...

vCluster - Create fully functional virtual Kubernetes clusters - Each vcluster runs inside a namespace of the underlying k8s cluster. It's cheaper than creating separate full-blown clusters and it offers better multi-tenancy and isolation than regular na
K8S 支持多种容器运行时环境,这里选择 docker 作为运行时环境,首先为所有节点服务器安装 docker,目前 kubernetes 最新版(v1.15.2) 可以完全兼容支持的 docker 最高版本为 v18.06,所以这里安装 v18.06 这个版本。 参考官网文档。 # 删除旧版本docker$sudoapt-getremovedockerdocker-engine docker.io containerd runc#...
在Kubernetes集群中,etcd用于存储集群的所有状态信息,包括Pods、Services、Deployments等。为了确保etcd的高可用性和数据持久性,通常会将其配置为静态Pod。静态Pod是由kubelet直接从宿主机的文件系统中读取并管理的,而不是通过API Server进行管理的。 2. 创建etcd静态Pod的YAML文件 为了创建etcd的静态Pod,你需要编写一个YA...
