Docker Network BasicsSince Kubernetes is based on the Docker container as the carrier of the application release, the network characteristics of Docker also determine that kubernetes in building a container interoperability network must solve the problem of Docker's own network.Network namespacesTo support multiple instances of the network protocol stack, Linux introduces a network namespace in the network
-speed storage to store a large number of fragmented files. What the user needs to do is submit the resource request to the cloud platform and then fetch and consume the storage resource without worrying about which disk of the storage server The underlying store is from. to meet the storage needs of container users in the cloud environment. Kubernetes provides the concept of persistent volumes (PERSISTENTVOLUME,PV) and persistent volume requests (PE
Summary: Kubernetes is Google open source container cluster management system, built on Docker, for containerized applications to provide resource scheduling, deployment operations, service discovery, capacity expansion and other functions. Pods are the smallest deployment units that are created, dispatched, and managed, and this article describes the communication and scheduling between these pods in detailOverviewThe Pods in

containers, making deployment and management more flexible. A pod can contain a container or multiple related containers. 2) Replication ControllerThe Replication Controller manages a copy of the pod to ensure that a specified number of pod copies exist in the cluster. If the number of replicas in the cluster is greater than the specified number, the number of extra containers that are outside the specified number is stopped, and conversely, containers with fewer than a specified
Hi,everybody, I came back, before the installation to flannel, the article has not been updated, even a lot of small partners to add QQ asked whether to continue to update,Here is the reason, I was in the deployment of 1.91node when there are a variety of problems, resulting in node startup Oh, master always do not see, the problem is probably1, Virtual machine time synchronization inconsistency problem, causing ETCD to create a resource is unsuccessful2, node nodes can not automatically create
Kubernetes can connect pods on different node nodes in the cluster, and by default, each pod is accessible to each other. However, in some scenarios, different pods should not be interoperable, and access control is required at this time. So how does it work?Brief introduction?? Kubernetes provides Networkpolicy feature, which supports network access control by namespace and by pod level. It uses the label

Today brings you a tutorial on creating a kubernetes cluster quickly with Docker. This tutorial is based on my previous article "10-minute deployment of kubernetes cluster," updated, condensed. This tutorial has been verified by me many times, and it has some guiding sign
what is kubernetes.
Kubernetes is a new, container-based distributed architecture leading solution. is an open source version of Google's internal cluster management system, Borg. It was not known until April 2015, when the papers were published. Kubernetes is an open platform for development. is not limited to any one language and does not qualify any programm

AlphaGo: each experiment has 1000 nodes and each node has 4 GPUs and 4000 GPUs. Siri: 2 nodes and 8 GPUs for each experiment. AI research relies on massive data computing, instead of performance computing resources. The larger cluster running model shortens the weekly training time to the day-level hour level. Kubernetes, the most widely used cont
The bottom of the Kubernetes node is supported by a software called a "container runtime," which is responsible for things like starting and stopping containers. The most well-known container runtime is Docker, but it is not unique. In fact, this field has developed rapidly in the container runtime. To make the expansion of kubernetes easier, we have been polishing the k8s plug-in API that supports containe

Kubernetes is a Borg open source-based container Orchestration Scheduler that manages the open source platform for automated deployment, expansion, and operation of container clusters. As one of the most important components of the CNCF (Cloud Native Computing Foundation) (CNCF another project Prometheus), its goal is not just an orchestration system, but a specification that allows you to describe the architecture of the cluster, Define the final sta
