Let's start with a simple example. 1. How to discover service in Kubernetes Discover

addition, the problems encountered by these new versions may not be found on the Internet. Kubernetes is not designed to be bound to the Google Cloud platform, but for the above reasons, to reduce unnecessary obstacles, we recommend using GCE as the runtime environment for the first attempt (although GCE is a charged environment ). By default, five GCE instances are created in the cluster STARTUP script. After the test, you must delete the instances

collection must know the addresses of all other nodes, but when a container is rearranged, its IP address changes. For example, all containers within a kubernetes share an IP address that changes after the pod is rearranged. In kubernetes, this problem can be resolved by contacting the Kubernetes service with the Mong

updates. such as our self-built computer room, the most depressed, not like some foreign public cloud so convenient, directly can download updates. How do you do it? First of all, you have to have a ladder, and then through the special Set update service, plus all_proxy, you can automatically update! To make it easier to use Yoo-installer, I plan to do two versions, one VM version, once downloaded, directly available, and the other Docker version. Prepared by the insufficient, did not finish,

, it takes a lot of time ). To solve this problem, the Volume abstraction Action feature in Kubernetes maps the MongoDB data folder to a persistent address to avoid container failure or rescheduling.The backup nodes of the same MongoDB database must communicate with each other, even after the re-arrangement. Nodes in the same redundant backup set must know the addresses of all other nodes. However, when a container is reconfigured, its IP address chan

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.

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, t

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 n

kubernetes Introduction Kubernetes is a container cluster management system that Google Open-source in June 2014, using the Go language development, Kubernetes also called k8s. K8s is a Borg container cluster management system inside Google, Borg has been operating on Google's mass production for 10 years. K8s is mainly used for automated deployment, expansion
