kubernetes 1.8 高可用安装（二）

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 kubernetes-admin@kubernetes \
  --cluster=kubernetes \
  --user=kubernetes-admin \
  --kubeconfig=admin.conf

# 设置默认上下文
kubectl config use-context kubernetes-admin@kubernetes --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
