manage applications. tags empower users to organize their resources on demand, and the annotation feature enables users to add customized information to specific resources to facilitate their workflow implementation and provides a workaround for the management tool's stateful inspection. In addition, the Kubernetes Control Panel is built based on APIs, which are also useful for developers and users, who can write their own controllers, dispatchers, a

selector: k8s-app:jenkins Description: We've lost our Service here. Ports 8080 and 50000,8080 are the default ports for accessing Jenkins Server page ports, 50000 for creating Jenkins Slave connecting with Master, and if not exposed, Slave cannot establish a connection with Master. Here, the Nodeport mode is used to leak the port, not specifying its port number, which is assigned by default by the Kubernetes system, and you can also specify a

What is a container?Kubernetes is a container management platform. It is conceivable that we need containers to manage them. But what is a container? The best answers to the official Docker documentation are: A container image is a lightweight, standalone, executable package that contains everything that can be run: Code, runtime, System tools, system libraries, settings. For Linux and Windows-based applications, containerized software can ru

Docker:Installing Docker,kubernetes on Minion calls the Docker API to create pods as a worker container, while kubernetes itself's agent thread can also run inside Docker. This kubernetes upgrade will be easier.Debian 7 under Install Docker can use Ubuntu source, run the following command:[email protected]:echo debhtt

What is 1.1 kubernetes?First, it is a new, container-based, distributed architecture leading solution. is an open source version of Google's Borg (large-scale cluster management system).Second, if the system design follows the Kubernetes design idea, then the traditional system architecture and business does not have much to do with the underlying code or function modules (such as load balancing, service se

(such as Pod), object name, and object namespace (namespace ). For a specific object type, each name is unique in its namespace. If an object name is not given in the namespace format, it is the default namespace, UID is unique in the range of time and space. More about services: Service is the abstraction of application services. It provides load balancing and Service discovery for applications through labels. The Pod IP address and port list matching labels constitute an endpoints, and kub

For example, if the registry host is Registry-host, 5000 ports are being used: Note that this spark-base is the underlying mirror image of the other mirrors.

time, if there is a request to come, there will be a request failure phenomenon. In the latest version, we added a health detection feature that allows users to specify their own service's monitoring and probing HTTP interface when they deploy a new version of the application, which is then added to the load balancer when the container service probe succeeds. This is not the case when deleting a container, and after executing the RC indent command, t

You can use the Systemctl status command to confirm:sudo systemctl status KubeletStart a single-node Kubernetes clusterThe Kubelet provides a convenient interface for the local System Management container.
