使用kubeadm(版本号v1.18.2)部署单Master节点k8s集群(二) k8s集群部署软件及配置-配置calico网络_calico-kube-controllers镜像放在master节点需要打标签吗-优快云博客

本文档详细介绍了如何使用kubeadm v1.18.2在单Master节点的k8s集群上配置Calico网络。首先，需要在所有主机上安装相关的Docker镜像，接着在Master节点创建并编辑多个Calico配置文件，包括calico-config.yaml, kdd-crds.yaml, rbac.yaml, calico-node.yaml 和 calico-kube-controllers.yaml。在配置过程中，需特别注意调整IP_AUTODETECTION_METHOD和CALICO_IPV4POOL_CIDR的设置，以匹配集群的网络环境。最后，在Master节点上应用这些资源清单文件，确保在应用前node节点已安装了所有必要的Calico镜像。" 119822455,7775390,Verilog实现SM控制器,"['硬件开发', 'Verilog', '数字电路', 'FPGA', '状态机设计']

安装calico网络的docker镜像

安装calico/node,/calico/cni,calico/kube-controllers,/calico/pod2daemon-flexvol镜像
3台主机都执行以下操作

docker pull docker.io/calico/node

docker pull docker.io/calico/cni

docker pull docker.io/calico/kube-controllers

docker pull docker.io/calico/pod2daemon-flexvol

在Master主节点上创建calico的配置文件

calico-config.yaml
kdd-crds.yaml
rbac.yaml
calico-node.yaml
calico-kube-controllers.yaml
