Configuring Multiple Clusters with Kubectl When doing Kubernetes-related development you usually end up managing several clusters. Kubectl provides multi-cluster context management. Kubectl’s configuration usually lives in $HOME/.kube/config or /etc/kubernetes/admin.conf. Log into the machine, look at the cluster configuration, and edit it using the format below.微信公众号KubernetesOperationsR&DkubectlHelmhttps://www.chenshaowen.com/en/blog/complex-application-management-framework-operator-for-kubernetes.htmlThu, 25 Jul 2019 00:00:00 +0000Thu, 25 Jul 2019 00:00:00 +0000https://www.chenshaowen.com/en/blog/complex-application-management-framework-operator-for-kubernetes.html1.
