依赖库 ksonnet 0.11.0以上版本 /可以直接从github上下载scp ks文件到usr/local/bin kubernetes 1.8以上直接使用CCE服务节点需要创建一个CCE集群和若干节点并为某个节点绑定EIP kubectl tools 1、安装ksonnet ksonnet 安装过程可以去网址里面查看ks最新版本
wget https://github.com/ksonnet/ksonnet/releases/download/v0.13.0/ks_0.13.0_linux_amd64.tar.gz
tar -vxf ks_0.13.0_linux_amd64.tar.gz
cd -vxf ks_0.13.0_linux_amd64
sudo cp ks /usr/local/bin安装完成后 安装显卡驱动
安装CUDA
sudo yum-config-manager --add-repo http://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-rhel7.repo
sudo yum clean all
sudo yum -y install nvidia-driver-latest-dkms cuda
sudo yum -y install cuda-drivers如缺少gcc依赖则实行如下命令 yum install kernel-devel kernel-doc kernel-headers gcc\* glibc\* glibc-\*安装nvidia驱动 rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.orgrpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpmyum install -y kmod-nvidia禁用nouvean
###在GRUB_CMDLINE_LINUX添加 rdblacklistnouveau 项
echo -e blacklist nouveau\noptions nouveau modeset0 /etc/modprobe.d/blacklist.conf重启查看nouveau是否被禁用成功
lsmod|grep nouv
没有任何输出则表示nouveau已被禁用查看服务器显卡信息

安装NVIDIA-DOCKER
下载nvidia-docker.repo文件
curl -s -L https://nvidia.github.io/nvidia-docker/centos7/x86_64/nvidia-docker.repo | sudo tee /etc/yum.repos.d/nvidia-docker.repo 查找NVIDIAdocker版本
yum search --showduplicates nvidia-docker安装NVIDIA-docker
docker版本为docker18.09.7.ce所以安装下述NVIDIAdocker版本
yum install -y nvidia-docker2
pkill -SIGHUP dockerdnvidia-docker version 可查看已安装的nvidia docker版本
修改docker runtimes为nvidia-docker
[rootks-allinone ~]# cat /etc/docker/daemon.json

关于镜像拉取gcr镜像国内无法拉取可以通过如下方式拉取
curl -s https://zhangguanzhang.github.io/bash/pull.sh | bash -s -- 镜像信息若上述方法也无法拉取可以使用阿里云手动构建镜像方式使用海外服务器构建
