环境准备
kubeflow 为环境要求很高，看官方要求：
at least one worker node with a minimum of:
- 4 CPU
- 50 GB storage
- 12 GB memory
当然，没达到也能安装，不过在后面使用中会出现资源问题，因为这是整包安装方案。
一个已经安装好的kubernetes集群，这里我采用的是rancher安装的集群。
sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher这里我选择的是k8s的1.14版本，kubeflow和k8s之间的版本兼容可以查看官网说明，这里我的kubeflow采用了0.6版本。
也可以直接创建阿里云kubernetes(记得需要选择1.14版本)：
如果直接想安装可以直接调到kubeflow一键安装部分
kustomize
下载kustomize文件
官方的教程是用 kfclt 安装的，kfclt 本质上是使用了 kustomize 来安装，因此这里我直接下载 kustomize 文件，通过修改镜像的方式安装。
官方kustomize文件下载地址
git clone https://github.com/kubeflow/manifests
cd manifests
git checkout v0.6-branch
cd <target>/base
kubectl kustomize . | tee <output file>文件比较多，可以用脚本分别导出，也可以用 kfctl 命令生成kfctl generate all -V:

]修改PVC，使用动态存储
修改pvc存储，采用local-path-provisioner动态分配PV。
安装local-path-provisioner：
kubectl apply -f https://raw.githubusercontent.com/rancher/local-path-provisioner/master/deploy/local-path-storage.yaml如果想直接在kubeflow中使用，还需要将StorageClass改为默认存储:
...
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: local-path
annotations: #添加为默认StorageClass
storageclass.beta.kubernetes.io/is-default-class: "true"
provisioner: rancher.io/local-path
volumeBindingMode: WaitForFirstConsumer
reclaimPolicy: Delete
...完成后可以建一个PVC试试：
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: local-path-pvc
namespace: default
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 2Gi注：如果没有设为默认storageclass需要在PVC加入storageClassName: local-path进行绑定
一键安装
