kubeadm join 超時報錯 error execution phase kubelet-start: error uploading crisocket: timed out waiting for the condition

問題分析：

可能是之前加入過k8s

解決方法：

kubeadm reset

之后重新加入即可。

 

報錯：[kubelet-check] The HTTP call equal to ‘curl -sSL http://localhost:10248/healthz’ failed with error: Get “http://localhost:10248/healthz”: dial tcp [::1]:10248: connect: connection refused.

問題分析：

之前我的Docker是用yum安裝的，docker的cgroup驅動程序默認設置為system。默認情況下Kubernetes cgroup為systemd，我們需要更改Docker cgroup驅動，

問題解決：

cat > /etc/docker/daemon.json << EOF

{

  "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"],

  "exec-opts": ["native.cgroupdriver=systemd"]

}
EOF

systemctl restart docker
docker info

之后在node節點執行

kubeadm join 192.168.1.35:6443 --token jeemo6.q7nxl1rrc81kh76h \
--discovery-token-ca-cert-hash sha256:7a433336427311c06ae00e06d5a04a7d89ffb509fba7eb48b6b24503b6778ba9

 

注意：192.168.1.35是master節點IP
