老师能不能换个别的部署方式,例如下载好需要的软件到本地,然后手动安装。这种yum安装的方式,费了老大劲配置好代理,结果 Connection to "https://192.168.100.221:6443" uses proxy "http://192.168.100.22:10086/". If that is not intended, adjust your proxy settings

先把科学上网搞好吧,一劳永逸。kubeadm部署本质上就是先将image从grc.io下载到本地。不解决上网的问题,后面的事情都没法弄了

提示说加 --skip-preflight-checks ,然而 后面到了
[init] This often takes around a minute; or longer if the control plane images have to be pulled.
之后就失败了
[kubelet-check] It seems like the kubelet isn't running or healthy.
[kubelet-check] The HTTP call equal to 'curl -sSL http://localhost:10255/healthz' failed with error: Get http://localhost:10255/healthz: dial tcp [::1]:10255: getsockopt: connection refused.
搞了两天解决不了

初始部署肯定不能使用 --skip-preflight-checks。问题还是在下载image上。在 /etc/kubernetes/manifests/ 目录下有几个yaml文件,里面有 k8s需要的image的路径,可以先通过 docker pull 手工下载image,然后再运行 kubeadm init

这个我试过了,应该有4个
image,gcr.io/google_containers/kube-apiserver-amd64,
gcr.io/google_containers/kube-controller-manager-amd64,
gcr.io/google_containers/kube-scheduler-amd64,
gcr.io/google_containers/etcd-amd64:3.0.17

docker 全都pull了,最后还是超时失败

这我就不明白了,既然image都有了,就应该能正常init。用docker ps 能看到相应的容器吗?另外,确保手工下载的image版本与yaml中的一致

Loading...

同样的问题。折磨死了。

主要还是网络问题,可参考上面的手工下载image的方法

请问下这个问题怎么解决的啊?手动拉也失败了

还要关闭swap?这个我还真没遇到过

[preflight] WARNING: docker version is greater than the most recently validated version. Docker version: 17.09.0-ce. Max validated version: 17.03
[preflight] WARNING: Connection to "https://10.10.103.25:6443" uses proxy "http://127.0.0.1:38251". If that is not intended, adjust your proxy settings
[preflight] Some fatal errors occurred:
/etc/kubernetes/manifests is not empty
running with swap on is not supported. Please disable swap
[preflight] If you know what you are doing, you can skip pre-flight checks with --skip-preflight-checks

直接init提示这个 ,然而我swapoff一直失败

先用 kubeadm reset 清理一下环境,另外建议用 apt-get install docker.io 安装 docker,这样安装出来的是 k8s 推荐的 docker 版本

/etc/kubernetes/manifests is not empty
这个是要 rm -rf /etc/kubernetes/manifests/*

manifests 是删了.
而swap怎么都关不掉,我也很无奈.

fstab注释了,重启
