1, if we open the Pea pod, and then click "Settings" as shown in the Red box "settings" as shown in the following figure. The Settings dialog box opens as shown below, and then we click on "System Settings" to open the entry 2, and then in the system default, we go to modify the default storage location, and then modify it. Well, finally, don't forget. Click OK, click OK, then our default path is changed successfully. Note: Small

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

Kubernetes API Server FeaturesThe core function of Kubernete API server is to provide an HTTP rest interface for kubernetes, deleting, changing, checking, and watch for various resource objects (such as Node,pod,service, etc.).The API server is the central hub for data interaction and communication between the various functional modules in the cluster, in additio

From Mesos to KubernetesThe previous scheduling framework was based on Mesos self-research. The language used is Python. Run for about two years, and has been relatively stable. But as the business grows, the problems of the existing framework are gradually exposed. Scheduling speed encountered bottlenecks, affecting the deployment of large business speed. There is no good support for stateful services. There are two solutions to this problem, one for improved refactoring of ex

features. The architecture of Kubernetes is not covered here, although the architecture is biased, but we finally decide to use it and try to use only its Pod,replicationtroller and service capabilities. Here are some concepts to explain first: User: Products, development, testing, operations and other personnel under various product lines. Region: A preference for geographical concepts such as Beiji

The content of this article has been validated based on k8s v1.8.8. K8s Service defines the access entry address of a server, the front-end application accesses a cluster of pod replicas behind it through this entry address, and the access requests from outside are load balanced to each container application on the back end. Between the service and the back-end pod replica cluster, the docking is done throu

Kubernetes 1.2 newly added some of the feature, because bloggers have not yet in-depth research, so not too much involved.1. HelpSimilar to all command-line tool tools, Kubectl can also execute the Usage: kubectl [Flags] Kubectl [Commond]In addition, all command options can be used to obtain help for specific commands by executing--help.2. GetThe GET command is used to get one or some resource information for a cluster. Use--help to view more i

/binding API in Kubernetes, Scheduler is responsible for pods allocations on each node. Scheduler is plug-in, Kubernetes can support user-defined scheduler in the future.4. Kubernetes Controller Manager ServerController Manager Server is responsible for all other functions, such as the endpoints controller responsible for creating and updating endpoints objects.

the concepts in Kubernetes node, Pod, Replication Controller, service, etc. can be considered as a "resource object", almost all resource objects can be implemented through the Kubectl tool (API call) to perform an increase, delete, change, Check the operation and save it in ETCD for persistent storage. From this point of view, Kubernetes is actually a highly au

cluster, it is containerized and deployed as a kubernetes pod. It also provides some additional functionality: You can choose how to deploy it (Deamon set runs on each node, or as a deployment of n replicas), configure health checks for it, and so on. When an application runs outside the cluster, it needs to manage it itself. The following configuration can make our tools more flexible and support two ways

Kubernetes is Google 's Open source container cluster management system. It is built on Docker technology and provides a whole set of functions, such as resource scheduling, deployment operation, service discovery, expansion and contraction capacity, for containerized applications, which can be regarded as Mini-paas platform based on container technology. The purpose of this article is to comb the architecture, concepts, and basic workflows of

-subnet isolation, network auditing/firewalls and security groups Next we look at the details of each function point.Kubernetes Kernel Depth CustomizationBased on kubernetes kernel depth customization, the Ecos-kubernetes platform cluster includes the master, ETCD, and node three roles. MASTER role : As the host node of the cluster, run a collection of three programs in the cluster, respectively: K

the service. Kube-proxy uses the ETCD watch mechanism to monitor the dynamic changes of service and endpoint object data in the cluster and to maintain a service-to-endpoint mapping From the page to ensure that the IP changes in the backend pod do not affect the visitor. Kube-proxy also supports session affinity.Kublet:kublet is the agent of master on each node, and is the most important module on node, and it is responsible for maintaining and manag

Kubernetes is a docker-based, open-source container cluster management system initiated and maintained by the Google team that not only supports common cloud platforms, but also supports internal data centers.Built on top of Docker, Kubernetes can build a container scheduling service that allows users to manage cloud container clusters through kubernetes clusters
