1 Kubeflow简介
1.1 什么是Kubeflow
来自官网的一段介绍： Kubeflow 项目致力于使机器学习 (ML) 工作流在 Kubernetes 上的部署变得简单、可移植和可扩展。 Kubeflow的目标不是重新创建其他服务，而是提供一种直接的方法，将用于 ML 的同类最佳开源系统部署到不同的基础设施中。 在任何运行 Kubernetes 的地方，开发者都应该能够运行 Kubeflow。
从官网这段介绍可以看出，Kubeflow与Kubernetes是形影不离的。总的来说，Kubeflow是 google 开源的一个基于 Kubernetes的 ML workflow 平台，其集成了大量的机器学习工具，比如用于交互性实验的 jupyterlab 环境，用于超参数调整的 katib，用于 pipeline 工作流控制的 argo workflow等。作为一个“大型工具箱”集合，kubeflow 为机器学习开发者提供了大量可选的工具，同时也为机器学习的工程落地提供了可行性工具。
1.2 Kubeflow 背景
Kubernetes 本来是一个用来管理无状态应用的容器平台，但是在近两年，有越来越多的公司用它来运行各种各样的工作负载，尤其是机器学习炼丹。各种 AI 公司或者互联网公司的 AI 部门都会尝试在 Kubernetes 上运行 TensorFlow，Caffe，MXNet 等等分布式学习的任务，这为 Kubernetes 带来了新的挑战。
首先，分布式的机器学习任务一般会涉及参数服务器（以下称为 PS）和工作节点（以下成为 worker）两种不同的工作类型。而且不同领域的学习任务对 PS 和 worker 有不同的需求，这体现在 Kubernetes 中就是配置难的问题。以 TensorFlow 为例，TensorFlow 的分布式学习任务通常会启动多个 PS 和多个 worker，而且在 TensorFlow 提供的最佳实践中，每个 worker 和 PS 要求传入不同的命令行参数。
其次，Kubernetes 默认的调度器对于机器学习任务的调度并不友好。如果说之前的问题只是在应用与部署阶段比较麻烦，那调度引发的资源利用率低，或者机器学习任务效率下降的问题，就格外值得关注。机器学习任务对于计算和网络的要求相对较高，一般而言所有的 worker 都会使用 GPU 进行训练，而且为了能够得到一个较好的网络支持，尽可能地同一个机器学习任务的 PS 和 worker 放在同一台机器或者网络较好的相邻机器上会降低训练所需的时间。
针对这些问题，Kubeflow 项目应运而生，它以 TensorFlow 作为第一个支持的框架，在 Kubernetes 上定义了一个新的资源类型：TFJob，即 TensorFlow Job 的缩写。通过这样一个资源类型，使用 TensorFlow 进行机器学习训练的工程师们不再需要编写繁杂的配置，只需要按照他们对业务的理解，确定 PS 与 worker 的个数以及数据与日志的输入输出，就可以进行一次训练任务。
一句话总结就是：Kubeflow 是一个为 Kubernetes 构建的可组合，便携式，可扩展的机器学习技术栈。
以上来自文章kubeflow–简介 https://www.jianshu.com/p/192f22a0b857，这段引言很好地解释了kubeflow的前生今世，对kubeflow的理解有了更深一层的认识，对于新手的我简直太需要了。
1.3 Kubeflow与机器学习
Kubeflow 是一个面向希望构建和进行 ML 任务的数据科学家的平台。Kubeflow 还适用于希望将 ML 系统部署到各种环境以进行开发、测试和生产级服务的 ML 工程师和运营团队。
Kubeflow 是 Kubernetes的 ML 工具包。
下图显示了 Kubeflow 作为在 Kubernetes 基础之上构建机器学习系统组件的平台：
kubeflow是一个胶水项目，它把诸多对机器学习的支持，比如模型训练，超参数训练，模型部署等进行组合并已容器化的方式进行部署，提供整个流程各个系统的高可用及方便的进行扩展部署了 kubeflow的用户就可以利用它进行不同的机器学习任务。
下图按顺序展示了机器学习工作流。工作流末尾的箭头指向流程表示机器学习任务是一个逐渐迭代的过程：
在实验阶段，您根据初始假设开发模型，并迭代测试和更新模型以产生您正在寻找的结果：
- 确定希望 ML 系统解决的问题；
- 收集和分析训练 ML 模型所需的数据；
- 选择 ML 框架和算法，并对模型的初始版本进行编码；
- 试验数据并训练您的模型。
- 调整模型超参数以确保最高效的处理和最准确的结果。
在生产阶段，您部署一个执行以下过程的系统：
- 将数据转换为训练系统需要的格式；
- 为确保模型在训练和预测期间表现一致，转换过程在实验和生产阶段必须相同。
- 训练 ML 模型。
- 为在线预测或以批处理模式运行的模型提供服务。
- 监控模型的性能，并将结果提供给您的流程以调整或重新训练模型。
ML 工作流中的 Kubeflow 组件如下图所示

2.3 前置环境
安装kubeflow需要的前置环境主要包括以下工具：
- Kubernetes ：最高1.21
- kustomize :3.2.0
- kubectl
https://github.com/kubeflow/manifests#prerequisites
3 Kubernetes 安装
k8s集群由Master节点和Node（Worker）节点组成,在这里我们只用1台机器，安装kubernetes。
3.1 查看ip
(base) [root@server-szry1agd ~]# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc pfifo_fast state UP group default qlen 1000
link/ether fa:16:3e:44:6c:3c brd ff:ff:ff:ff:ff:ff
inet 192.168.3.130/22 brd 192.168.3.255 scope global noprefixroute dynamic eth0
valid_lft 80254sec preferred_lft 80254sec
inet6 fe80::f816:3eff:fe44:6c3c/64 scope link
valid_lft forever preferred_lft forever
3.2 修改主机名称
这一步不是必须的，我看到有的文章里面讲到主机名称不能有下划线
(base) [root@server-szry1agd ~]# hostnamectl set-hostname kubuflow && bash
修改前后对比
3.3 添加host
这里需要改成自己的ip和主机名称
(base) [root@kubuflow ~]# cat >> /etc/hosts << EOF
> 192.168.3.130 kubuflow
> EOF
查看hosts
(base) [root@kubuflow ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
0.0.0.0 server-szry1agd.novalocal
192.168.3.130 kubuflow
3.4 关闭防火墙,关闭selinux
(base) [root@kubuflow ~]# systemctl stop firewalld
(base) [root@kubuflow ~]# systemctl disable firewalld
(base) [root@kubuflow ~]# sed -i 's/enforcing/disabled/' /etc/selinux/config # 永久
(base) [root@kubuflow ~]# setenforce 0 # 临时
setenforce: SELinux is disabled
3.5 关闭swap
(base) [root@kubuflow ~]# swapoff -a
(base) [root@kubuflow ~]# sed -i 's/.*swap.*/#&/' /etc/fstab
3.6 转发 IPv4 并让 iptables 看到桥接流量
通过运行 lsmod | grep br_netfilter 来验证 br_netfilter 模块是否已加载。 若要显式加载此模块，请运行 sudo modprobe br_netfilter。 为了让 Linux 节点的 iptables 能够正确查看桥接流量，请确认 sysctl 配置中的 net.bridge.bridge-nf-call-iptables 设置为 1。
cat <<EOF | sudo tee /etc/modules-load.d/k8s.conf
overlay
br_netfilter
EOF
sudo modprobe overlay
sudo modprobe br_netfilter
# 设置所需的 sysctl 参数，参数在重新启动后保持不变
cat <<EOF | sudo tee /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
net.ipv4.ip_forward = 1
EOF
# 应用 sysctl 参数而不重新启动
sudo sysctl --system
3.7 时间同步
(base) [root@kubuflow ~]# yum install ntpdate -y
(base) [root@kubuflow ~]# ntpdate time.windows.com
24 Dec 14:21:55 ntpdate[18177]: adjust time server 52.231.114.183 offset 0.003717 sec
3.8 安装docker
wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
yum -y install docker-ce
systemctl enable docker && systemctl start docker && systemctl status docker
安装成功
(base) [root@kubuflow ~]# docker --version
Docker version 20.10.22, build 3a2c30b
(base) [root@kubuflow ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
(base) [root@kubuflow ~]#
3.9 docker添加国内镜像源
(base) [root@kubuflow ~]# cat > /etc/docker/daemon.json << EOF
> {
> "registry-mirrors": [
> "http://hub-mirror.c.163.com",
> "https://docker.mirrors.ustc.edu.cn",
> "https://registry.docker-cn.com"
> ]
> }
> EOF
(base) [root@kubuflow ~]# # 使配置生效
(base) [root@kubuflow ~]# systemctl daemon-reload
(base) [root@kubuflow ~]#
(base) [root@kubuflow ~]# # 重启Docker
(base) [root@kubuflow ~]# systemctl restart docker
3.10 添加kubernetes的yum源
(base) [root@kubuflow ~]# cat > /etc/yum.repos.d/kubernetes.repo << EOF
> [kubernetes]
> name=Kubernetes
> baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
> enabled=1
> gpgcheck=0
> repo_gpgcheck=0
> gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
> https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
> EOF
3.11 安装kubeadm，kubelet 和kubectl
(base) [root@kubuflow ~]# yum -y install kubelet-1.21.5-0 kubeadm-1.21.5-0 kubectl-1.21.5-0
(base) [root@kubuflow ~]# systemctl enable kubelet
3.12 部署Kubernetes Master
(base) [root@kubuflow ~]# kubeadm init --apiserver-advertise-address=192.168.3.130 --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.21.5 --service-cidr=10.96.0.0/12 --pod-network-cidr=10.244.0.0/16 --ignore-preflight-errors=all
参数说明：
- –apiserver-advertise-address=192.168.3.130
这个参数就是master主机的IP地址，例如我的Master主机的IP是：192.168.3.130，也是我们在2.4.1看到的ip地址 - –image-repository registry.aliyuncs.com/google_containers
这个是镜像地址，由于国外地址无法访问，故使用的阿里云仓库地址：repository
registry.aliyuncs.com/google_containers - –kubernetes-version=v1.21.5 这个参数是下载的k8s软件版本号
- –service-cidr=10.96.0.0/12 这个参数后的IP地址直接就套用10.96.0.0/12
,以后安装时也套用即可，不要更改 - –pod-network-cidr=10.244.0.0/16
k8s内部的pod节点之间网络可以使用的IP段，不能和service-cidr写一样，如果不知道怎么配，就先用这个10.244.0.0/16 - –ignore-preflight-errors=all 添加这个会忽略错误
执行语句后，看到如下的信息说明就安装成功了。
[addons] Applied essential addon: CoreDNS
[addons] Applied essential addon: kube-proxy
Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
Alternatively, if you are the root user, you can run:
export KUBECONFIG=/etc/kubernetes/admin.conf
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.3.130:6443 --token nupk90.vnoqbfgexf8d2lhp \
--discovery-token-ca-cert-hash sha256:715fac4463bd6b5b4de53e9356002eed12652fa8c6def12789ccb5d6f73fefaa

3.18 部署和访问 Kubernetes 仪表板（Dashboard）
默认情况下不会部署 Dashboard。可以通过以下命令部署：
kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.1/aio/deploy/recommended.yaml
查看是否在运行
(base) [root@kubuflow ~]# kubectl get pod -n kubernetes-dashboard

kubernetes-dashboard-6b79449649-4kgsx 1/1 Running 0 16m
将ClusterIP类型改为NodePort,使用 : 从集群外部访问Service
(base) [root@kubuflow ~]# kubectl edit svc kubernetes-dashboard -n kubernetes-dashboard
type: ClusterIP修改为type: NodePort，保存后使用kubectl get svc -n kubernetes-dashboard命令来查看自动生产的端口：
(base) [root@kubuflow ~]# kubectl get svc -n kubernetes-dashboard
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
dashboard-metrics-scraper ClusterIP 10.98.238.142 <none> 8000/TCP 25m
kubernetes-dashboard NodePort 10.105.207.158 <none> 443:30988/TCP 25m
如上所示，Dashboard已经在30988/端口上公开，现在可以在外部使用https://:30988/进行访问。

4 Kubeflow安装
4.1 下载官方安装脚本仓库
安装1.6.0版本
(base) [root@kubuflow softwares]# wget https://github.com/kubeflow/manifests/archive/refs/tags/v1.6.0.zip
(base) [root@kubuflow ~]# unzip v1.6.0.zip
(base) [root@kubuflow ~]# unzip v1.6.0.zip mv manifests-1.6.0/ manifests
4.2 下载安装kustomize
https://github.com/kubernetes-sigs/kustomize
curl -s "https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh" | bash
如果下载比较慢的话，可以使用代理进行github加速
(base) [root@kubuflow softwares]# curl -s "https://ghproxy.com/https://raw.githubusercontent.com/kubernetes-sigs/kustomize/master/hack/install_kustomize.sh" | bash
添加到bin
cp kustomize /bin/
kustomize version
4.3 镜像同步至dockerhub方式
由于kubeflow有些组件的镜像是国外的，所以需要解决国外谷歌镜像拉取问题，具体可以参考一个大佬分享的帖子：
kubeflow国内环境最新安装方式 https://zhuanlan.zhihu.com/p/546677250
### 获取gcr镜像，因为我的网络只无法获取gcr.io, quay.io正常，可以根据需求修改
kustomize build example |grep 'image: gcr.io'|awk '$2 != "" { print $2}' |sort -u
### 使用github-ci同步至个人dockerhub仓库
https://github.com/kenwoodjw/sync_gcr
修改https://github.com/kenwoodjw/sync_gcr/blob/master/images.txt 提交会触发ci同步镜像至dockerhub
可根据需求修改https://github.com/kenwoodjw/sync_gcr/blob/master/sync_image.py
4.4 准备sc、pv、pvc
kubeflow的组件需要存储，所以需要提前准备好pv，本次实验存储采用的本地磁盘存储的方式。流程如下:
这里需要小心，名字和路径需要写对，按照下面步骤进行，或者根据自己创建的路径仔细修改
- 准备本地目录
mkdir -p /data/k8s/istio-authservice /data/k8s/katib-mysql /data/k8s/minio /data/k8s/mysql-pv-claim
修改auth路径权限
sudo chmod -R 777 /data/k8s/istio-authservice/
- 编写kubeflow-storage.yaml
hostPath: path: "/data/k8s/istio-authservice"改成上面各自创建的目录
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

apiVersion: v1

执行
kubectl apply -f kubeflow-storage.yaml
4.5 修改安装脚本拉取镜像
(base) [root@kubuflow example]# cat kustomization.yaml
将manifests/example/kustomization.yaml文件内容修改如下，就是后面添加images，这个相当于把谷歌（gcr.io, quay.io）的镜像同步到了dockerhub：

修改yaml，下面每个文件里面添加 storageClassName: local-storage
apps/katib/upstream/components/mysql/pvc.yaml
apps/pipeline/upstream/third-party/minio/base/minio-pvc.yaml
apps/pipeline/upstream/third-party/mysql/base/mysql-pv-claim.yaml
common/oidc-authservice/base/pvc.yaml
4.6 一键安装
https://github.com/kubeflow/manifests#install-with-a-single-command
(base) [root@kubuflow manifests]# pwd
/root/softwares/manifests
(base) [root@kubuflow manifests]# while ! kustomize build example | kubectl apply -f -; do echo "Retrying to apply resources"; sleep 10; done
2022/12/24 16:23:51 well-defined vars that were never replaced: kfp-app-name,kfp-app-version
等大部分pods创建完毕之后，结果输出如下：
最后报错的地方 error: resource mapping not found for name: “kubeflow-user-example-com” namespace: “” from “STDIN”: no matches for kind “Profile” in version “kubeflow.org/v1beta1”,我们可以先忽略，这个好像是官方的一个kubeflow例子，具体也可以参考分步安装的步骤：
https://github.com/kubeflow/manifests#user-namespace
kustomize build common/user-namespace/base | kubectl apply -f -
过上一会(可以打会游戏了，耐心等待，中间会拉去每个pod镜像以及容器创建，所以比较慢)，我们可以看下pods的状态,全部为running说明一路绿灯，可以访问kubeflow dashbord了
(base) [root@kubuflow ~]# kubectl get pods --all-namespaces
我们查看k8s的dashboard，也可以看到所有的pod都是正常运行的
4.7 访问Kubeflow Dashboard
kubectl port-forward --address 0.0.0.0 svc/istio-ingressgateway -n istio-system 8080:80
--address 0.0.0.0代表可以外部host访问，不加的话只能本地访问
默认用户名和密码：
user@example.com
12341234
只能http访问，https有问题
