kubernetes初始化报错Get "http://localhost:10248/healthz": dial tcp 127.0.0.1:10248: connect: connection refused.的解决办法

k8s使用kubeadm初始化报如下错误:

[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10248/healthz' failed with error: Get "http://localhost:10248/healthz": dial tcp 127.0.0.1:10248: connect: connection refused.

原因:

docker的cgroup驱动程序默认设置为system。默认情况下Kubernetes cgroup为systemd,我们需要更改Docker cgroup驱动,

解决办法:

kubeadm reset

vim /etc/docker/daemon.json

{
  "registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"],
  "exec-opts": ["native.cgroupdriver=systemd"]
}

[root@master01 ~]# systemctl daemon-reload

systemctl restart docker

重新初始化即可成功。
