2、设置kubeconfig
2.1 设置kubectl的kubeconfig（admin.conf）
# 设置集群参数 kubectl config set-cluster kubernetes --certificate-authority=/etc/kubernetes/pki/ca.pem --embed-certs=true --server=https://master_VIP:6443 --kubeconfig=admin.conf # 设置客户端认证参数 kubectl config set-credentials kubernetes-admin --client-certificate=/etc/kubernetes/pki/admin.pem --embed-certs=true --client-key=/etc/kubernetes/pki/admin-key.pem --kubeconfig=admin.conf # 设置上下文参数 kubectl config set-context [email protected] --cluster=kubernetes --user=kubernetes-admin --kubeconfig=admin.conf # 设置默认上下文 kubectl config use-context [email protected] --kubeconfig=admin.conf
2.2 配置 bootstrap.kubeconfig
# 生成配置
cd /etc/kubernetes/
export BOOTSTRAP_TOKEN=$(head -c 16 /dev/urandom | od -An -t x | tr -d ‘ ‘)
export KUBE_APISERVER="https://master_VIP:6443"
echo "Token: ${BOOTSTRAP_TOKEN}"
# 生成token文件
cat > token.csv <<EOF
${BOOTSTRAP_TOKEN},kubelet-bootstrap,10001,"system:kubelet-bootstrap"
EOF
#设置集群参数
kubectl config set-cluster kubernetes --certificate-authority=/etc/kubernetes/pki/ca.pem --embed-certs=true --server=${KUBE_APISERVER} --kubeconfig=bootstrap.kubeconfig
# 设置客户端认证参数
kubectl config set-credentials kubelet-bootstrap --token=${BOOTSTRAP_TOKEN} --kubeconfig=bootstrap.kubeconfig
# 设置上下文参数
kubectl config set-context default --cluster=kubernetes --user=kubelet-bootstrap --kubeconfig=bootstrap.kubeconfig
# 设置默认上下文
kubectl config use-context default --kubeconfig=bootstrap.kubeconfig
2.3生成kube-proxy.kubeconfig
#设置集群参数
kubectl config set-cluster kubernetes --certificate-authority=/etc/kubernetes/pki/ca.pem --embed-certs=true --server=${KUBE_APISERVER} --kubeconfig=kube-proxy.kubeconfig
# 设置客户端认证参数
kubectl config set-credentials kube-proxy --client-certificate=/etc/kubernetes/pki/kube-proxy.pem --client-key=/etc/kubernetes/pki/kube-proxy-key.pem --embed-certs=true --kubeconfig=kube-proxy.kubeconfig
# 设置上下文参数
kubectl config set-context default --cluster=kubernetes --user=kube-proxy --kubeconfig=kube-proxy.kubeconfig
# 设置默认上下文
kubectl config use-context default --kubeconfig=kube-proxy.kubeconfig
