使用kubeadm部署k8s集群05-配置kubectl访问kube-apiserver

2018/1/4

配置 kubectl 访问 kube-apiserver

• 切换 master 节点连接到本节点的 apiserver
• 确认集群信息

切换 master 节点连接到本节点的 apiserver

### 为了在这 2 个新的节点执行 kubectl 需要配置 admin.yaml
[[email protected] ~]# mkdir -p ~/k8s_install/master/admin
[[email protected] ~]# cd !$

[[email protected] admin]# cp -a /etc/kubernetes/admin.conf tvm-01.admin.conf
[[email protected] admin]# sed -i ‘s#10.10.9.67:6443#10.10.9.68:6443#‘ tvm-01.admin.conf
[[email protected] admin]# scp tvm-01.admin.conf 10.10.9.68:/etc/kubernetes/admin.conf

[[email protected] ~]# mkdir -p $HOME/.kube
[[email protected] ~]# cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

### 同样的操作，在另一个节点上执行：
[[email protected] admin]# cp -a /etc/kubernetes/admin.conf tvm-02.admin.conf
[[email protected] admin]# sed -i ‘s#10.10.9.67:6443#10.10.9.69:6443#‘ tvm-02.admin.conf
[[email protected] admin]# scp tvm-02.admin.conf 10.10.9.69:/etc/kubernetes/admin.conf

[[email protected] ~]# mkdir -p $HOME/.kube
[[email protected] ~]# cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

确认集群信息

[[email protected] ~]# kubectl cluster-info
Kubernetes master is running at https://10.10.9.68:6443
KubeDNS is running at https://10.10.9.68:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump‘.

[[email protected] ~]# kubectl cluster-info
Kubernetes master is running at https://10.10.9.69:6443
KubeDNS is running at https://10.10.9.69:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use ‘kubectl cluster-info dump‘.

### 上述信息显示，每个节点已经连接到本机的 apiserver 上
