描述

当我需要扩展master节点时，在主节点执行kubeadm init phase upload-certs --upload-certs报错

[root@k8s-master-01 pki]# kubeadm init phase upload-certs --upload-certs
Found multiple CRI endpoints on the host. Please define which one do you wish to use by setting the 'criSocket' field in the kubeadm configuration file: unix:///var/run/containerd/containerd.sock, unix:///var/run/cri-dockerd.sock
To see the stack trace of this error execute with --v=5 or higher

当加上cri-socket参数仍旧行不通

[root@k8s-master-01 pki]# kubeadm init phase upload-certs --upload-certs  --cri-socket /var/run/cri-dockerd.sock
unknown flag: --cri-socket
To see the stack trace of this error execute with --v=5 or higher

原因

kubeadm init phase upload-certs --upload-certs --help 查看，原因旧是没有这个–cri-socket选项
found multiple cri endpoints on the host. please define which one do you wis,kubernetes,容器,云原生

解决

cat <<EOF > kubeadm-init-config
apiVersion: kubeadm.k8s.io/v1beta3
kind: InitConfiguration
nodeRegistration:
  criSocket: /var/run/cri-dockerd.sock   #改为你的地址
EOF

重新执行upload-certs并带上–config文章来源地址https://www.toymoban.com/news/detail-813766.html

[root@k8s-master-01 pki]# kubeadm init phase upload-certs --upload-certs --config kubeadm-init-config
