label is the basis for running the replication controller and service, and they are associated with the pod running on node with a label.5) Nodenode is the service node (or agent) that runs the pod in the Kubernetes cluster schema. node is a unit of Kubernetes cluster operation that hosts the running of the allocated pod and is the host on which the pod runs.2.

Once again, the architecture is clear: three virtual machine CentOS 7.4 systems, Docker 17, IP 10.10.90.105 to 107, 105-bit master, and the next master-related components installed on this machine.The ETCD cluster is 3 units, which are reused for each of the 3 virtual machines.As the core of k8s, the master node consists of three components, namely:Three components:kube-apiserverkube-schedulerkube-controller-managerThis three components are closely li

Kubernetes Basic Primer-Installation Deployment Configuration ExampleDeploying Kubernetes SkydnsKubernetes can provide DNS internal domain name resolution services for pods.Its main function is to provide pods with the ability to resolve the IP directly through the service's name to the corresponding service!1. First add the options in the Kubelet process for each node:kubelet_args= "--cluster_dns=10.254.0.10--cluster_domain=kube.local"The Master node operates as follows:[email protected] master

configured, it Kubernetes is really not simple (in my experience), you can view this kubernetes the hard. But at least for now, we don't have to worry about it. Now, the first cool part is that there is Kubernetes great potential for developers to easily deploy services to production environments. This is really cool, using Kubernetes work, you can really start a new service in 5 minutes with a profile HTTP (including "Start 5 service Programs", "Configure load Balancing", "Configure DNS"), wor

MasterThe following steps are performed on master Installing ETCD and kubernetes through Yum Yum-y Install ETCD kubernetes2. Modify the configuration file/etc/etcd/etcd.conf, make sure ETCD listens to all addresses, modify the following:Etcd_name=defaultetcd_data_dir= "/var/lib/

Kubernetes-initial experience of Google distributed container Technology Kubernetes is an open-source container Cluster Management System of Google. The four features of the distributed service framework written a few days ago mentioned that a good distributed service framework needs to be implemented. Service configuration management. Including service discovery, Server Load balancer, and service dependency management.Inter-service scheduling and lifecycle management. Kubernetes includes some o
