Teaches you how to accelerate the deployment of k8s in China and implement custom settings that have a k8s image of the warehouse with its namespace.OverviewKubernetes is a powerful container orchestration tool that enables users to reliably deploy and run containerized applications on a scalable system. Within the container area, k8s has undoubtedly become a community standard for container orchestration and management, and even Docker has announced support for K8s. The fighting in the field of

The previous blog post describes the deployment of the K8s cluster, which focuses on deploying Kube-dns and dashboard.Environment descriptionNode-1 (Master): 10.0.0.1Node-2:10.0.0.2Node-3:10.0.0.3The cluster uses a binary installation, and the Flannel network plug-in is deployed.Kube-dns When doing the following, you must have already deployed the k8s cluster, if you do not have such a cluster, please refer to my previous blog post. 1, find the corresponding Yaml file on the offici

First of all, we need to understand the function of kubernetes, in short, it provides a container orchestration technology, to provide users with a container-based service rapid deployment, upgrade, rollback, access control, elastic scaling and other scheduling functions, so that users in the development, testing, production environment can achieve agile development, The purpose of fast and reliable delivery.Second, you need to understand the kubernet

Kubernetes is Google open source container choreographer, very suitable for the current hot micro-service architecture, in the Container choreography field, is gradually building a dominant position. This article mainly aims at the Kubernetes service to do some analysis, first briefly introduces the basic concept.

Set startup parameters for the container startup command (set to environment variable). Mou

Use Google Cloud deployment Manager to install and run Istio's quick start instructions in Google kubernetes Engine(Gke). This quick start is used to create a new Gke cluster, install Istio, and then deploy the BookInfo sample application. It is performed automatically using Deployment Manager and is described in detail in the istio on kubernetes setup Guide . Note: The default installation creates a Gke Al

first, the core concept 1, Node node as a working node in a cluster, running a real application, the smallest unit of Kubernetes managed on node is pod. Node runs kubernetes kubelet, Kube-proxy service processes that are responsible for pod creation, start-up, monitoring, restart, destruction, and load balancing of software patterns. Node contains information: node address: The IP address of the host, or

Linux people are not very united, I personally think. there are already many releases of linux and the open-source community. It is said that there are more than 500 releases of linux.

In the coding process, there are some common code modules, sometimes we do not want to copy to the rough reuse, because this can not only reflect the changes, but also not conducive to unified management. Here we use the Maven deploy approach to make generic modules into jar packages, publish to Nexus, and let other projects refer to them for reuse and management in a more concise and efficient way.First: Maven settings Server> ID>ReleaseID> username>Adminusername> Password>Ad

About Kubernetes Master Multi-node and high-availability, the online approach takes a active-standby approach, namely:Using software such as pacemaker makes certain master services (Apiserver,scheduler,controller-manager) run only one instance at a time. Specifically, if you have more than one master node, Scheduler,controller-manager is installed on it, Apiserver: For Schduler services, run only on one master node at a time, For Controll

Both C2container Service (ECS) and Kubernetes (k8s) solve the same problem: spanning the host cluster Management container . The battle between ECS and Kubernetes reminds me of the battle between the editor of VI and Emacs: The intense discussion focused on technical issues and personal beliefs. The next question will help you choose wisely. Considering the question and the answer contains my claim to the d

time, it will be more mature. Features are simple and limited. KubernetesKubernetes is a Google-led production-Ready, enterprise-class, mature orchestration platform. Its pros and cons are:Advantages: Production-Ready, enterprise-class. It is used by many companies for scale production environments. It is more mature than Docker Swarm. It can be used in many cloud environments such as public cloud, private cloud, hybrid cloud, etc. Modular. Self-healing capabil

This is a creation in Article, where the information may have evolved or changed. This series of documentation describes kubernetes all the steps of using a binary deployment cluster, rather than kubeadm deploying the cluster using automated methods; During deployment, the startup parameters of each component are listed in detail, their meanings, and the problems they may encounter. Once the deployment is complete, you will understand the interaction
