This article mainly explains the "steps to install dashboard in Kubernetes". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn the steps of installing dashboard in Kubernetes.

1. Preparatory work

See CentOS7 configuration Kubernetes (K8S) cluster here using K8s version 1.5.2

Modify the ip address here to 0.0.0.0 and 192.168.0.51 (master address). Here, point the pod-infra to the local image pod-infra-container-image=docker.io/openshift/origin-pod:latest, which needs to be configured on both master and slave.

4.2 apiserver#### kubernetes system config## The following values are used to configure the kube-apiserver## The address on the local server to listen to.KUBE_API_ADDRESS= "--insecure-bind-address=0.0.0.0" # The port on the local server to listen on.# KUBE_API_PORT= "--port=8080" # Port minions listen on# KUBELET_PORT= "--kubelet-port=10250" # Comma separated list of nodes in the etcd clusterKUBE_ETCD_SERVERS= "--etcd-servers= http://192.168 .0.51 default admission control policies#KUBE_ADMISSION_CONTROL= 2379 "# Address range to use for servicesKUBE_SERVICE_ADDRESSES="-- service-cluster-ip-range=10.254.0.0/16 "# default admission control policies#KUBE_ADMISSION_CONTROL="-- admission-control=NamespaceLifecycle NamespaceExists,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota "KUBE_ADMISSION_CONTROL="-- admission-control=NamespaceLifecycle,NamespaceExists,LimitRanger,SecurityContextDeny,ResourceQuota "# Add your owning KUBE APISAGSs ="

4.3 pod-infrastructure

You need to use this image when installing Pod. Prepare it in advance, otherwise it will not be available because of GW.

Download a mirror image

[root@k8s-master elk] # docker pull docker.io/openshift/origin-pod

For the same reason, prepare the image of dashboard in advance

Here I choose the first mirror image.

Docker pull docker.io/mritd/kubernetes-dashboard-amd64

Image preparation, which is done on both the master and the server

5. Enter the interface

Enter the page via http://192.168.0.51:8080/ui, that is, the host ip and apiserver ports

Thank you for your reading, the above is the "Kubernetes installation of dashboard steps" content, after the study of this article, I believe you have a deeper understanding of the steps of Kubernetes installation of dashboard, the specific use of the need for you to practice and verify. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
