k8s安装3节点集群Fate v1.8.0
采用k8s，而非minikube, 在3个centos系统的节点上安装fate集群。
本人安装这个v1.8.0版本后，能登陆fateboard，但无法传输数据，问题无法解决。于是选择安装v1.7.2版本，配置更为具体，步骤更为清晰，请参考《k8s安装3节点集群Fate v1.7.2》：
https://blog.csdn.net/Acecai01/article/details/128253844?csdn_share_tail=%7B%22type%22%3A%22blog%22%2C%22rType%22%3A%22article%22%2C%22rId%22%3A%22128253844%22%2C%22source%22%3A%22Acecai01%22%7D
集群配置信息
3节点配置信息如下图：
当kubefate最新版是1.9.0时，依赖的k8s和ingress-ngnix版本如下：
Recommended version of dependent software:
Kubernetes: v1.23.5
Ingress-nginx: v1.1.3
升级K8S到1.23.5
如果你的集群k8s版本高于1.19.0，可以直接跳过本步骤。
参考博客
https://blog.csdn.net/RivenDong/article/details/121213109
https://www.cnblogs.com/cloud-yongqing/p/16629666.html
以下步骤多次操作，逐级将K8S从1.18.x升级到1.23.5
master节点
yum install -y kubeadm-1.19.16-0 --disableexcludes=kubernetes
kubeadm version
kubectl drain harbor.clife.io --delete-emptydir-data --ignore-daemonsets
kubeadm upgrade plan --ignore-preflight-errors=CoreDNSUnsupportedPlugins,CoreDNSMigration
kubeadm upgrade apply v1.19.16 --ignore-preflight-errors=CoreDNSUnsupportedPlugins,CoreDNSMigration
yum install -y kubelet-1.19.16-0 kubectl-1.19.16-0
systemctl daemon-reload
systemctl restart kubelet
kubectl uncordon harbor.clife.io
节点gpu-51
master节点执行: kubectl drain gpu-51 --ignore-daemonsets
yum install -y kubeadm-1.20.15-0 --disableexcludes=kubernetes
kubeadm upgrade node
yum install -y kubelet-1.20.15-0 kubectl-1.20.15-0 --disableexcludes=kubernetes
systemctl daemon-reload
systemctl restart kubelet
master节点执行: kubectl uncordon gpu-51
删除旧版Fate
如果你的集群未安装过Fate，跳过本步骤
查看之前已安装的f旧版fate，将其删除：
查看：
kubectl get ns

接下来的操作都在Master节点上完成。
部署ingress-nginx
参考：https://blog.csdn.net/qq_41296573/article/details/125809696
以下deploy.yaml为部署ingress-nginx（1.1.3版本，当时最新1.5.0）的文件，可能需要才能下载：
https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.3/deploy/static/provider/cloud/deploy.yaml
以上文件中有2个才能下载的镜像，将镜像改成国内的镜像（3处地方）：
k8s.gcr.io/ingress-nginx/controller:v1.1.3@sha256:31f47c1e202b39fadecf822a9b76370bd4baed199a005b3e7d4d1455f4fd3fe2
改为：
registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:v1.1.3
k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660
改为：
registry.cn-hangzhou.aliyuncs.com/google_containers/kube-webhook-certgen:v1.1.1
然后部署ingress-nginx：
kubectl apply -f ./deploy.yaml
查看ingress-nginx是否成功：
[root@harbor kubefate]# kubectl get pods -n ingress-nginx -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
ingress-nginx-admission-create-zh96h 0/1 Completed 0 2d23h 10.244.1.26 gpu-51
ingress-nginx-admission-patch-hmgr5 0/1 Completed 1 2d23h 10.244.1.27 gpu-51
ingress-nginx-controller-6995ffb95b-m87gh 1/1 Running 0 2d18h 172.17.0.8 k8s-node02
可见ingress-nginx被安装到了k8s-node02节点，而不是master节点，这个是正常的（即便是在master操作，也会安装到别处）
输入如下命令，检查配置是否生效：
kubectl -n ingress-nginx get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
ingress-nginx-controller LoadBalancer 10.1.196.14 80:30428/TCP,443:30338/TCP 16m
ingress-nginx-controller-admission ClusterIP 10.1.32.33 443/TCP 16m
可以看到ingress-nginx-controller的EXTERNAL-IP为pending状态，经查阅资料，借鉴如下博客：
链接: link
修改 service中ingress-nginx-controller的EXTERNAL-IP为k8s-node02节点的IP：
kubectl edit -n ingress-nginx service/ingress-nginx-controller
在大概如下位置添加externalIPs:
spec:
allocateLoadBalancerNodePorts: true
clusterIP: 10.1.86.240
clusterIPs:
- 10.1.86.240
externalIPs:
- 10.6.17.106
再次查看，EXTERNAL-IP已经有了：
[root@harbor kubefate]# kubectl -n ingress-nginx get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
ingress-nginx-controller LoadBalancer 10.1.86.240 10.6.17.106 80:31872/TCP,443:32412/TCP 2d23h
ingress-nginx-controller-admission ClusterIP 10.1.41.173 443/TCP 2d23h
部署Kubefate服务
1.载入Kubefate服务镜像
接着，我们下载KubeFATE服务镜像v1.4.4：
curl -LO https://github.com/FederatedAI/KubeFATE/releases/download/v1.8.0/kubefate-v1.4.4.docker
注意：前边是v1.8.0后边是v1.4.4
然后读入本地Docker环境
docker load < kubefate-v1.4.4.docker
创建目录
mkdir /home/FATE_V180
将kubefate-k8s-v1.8.0.tar.gz拷贝到新目录中解压
tar -zxvf kubefate-k8s-v1.8.0.tar.gz
解压后的目录，可见可执行文件KubeFATE，可以直接移动到path目录方便使用：
chmod +x ./kubefate && sudo mv ./kubefate /usr/bin
测试下kubefate命令是否可用：
kubefate version
* kubefate commandLine version=v1.4.4
* kubefate service connection error, resp.StatusCode=404, error:
404 - Not Found
404 - Not Found
以上提示的问题算正常，后面会解决。
执行rbac-config.yaml–为 KubeFATE服务创建命名空间
kubectl apply -f ./rbac-config.yaml
因为近期Dockerhub调整了下载限制服务条例 Dockerhub latest limitation, 我建议使用国内网易云的镜像仓库代替官方Dockerhub
1、将kubefate.yaml内镜像federatedai/kubefate:v1.4.4改成hub.c.163.com/federatedai/kubefate:v1.4.4
2、sed 's/mariadb:10/hub.c.163.com\/federatedai\/mariadb:10/g' kubefate.yaml > kubefate_163.yaml
3、sed 's/registry: ""/registry: "hub.c.163.com\/federatedai"/g' cluster.yaml > cluster_163.yaml
在kube-fate命名空间里部署KubeFATE服务，相关的yaml文件也已经准备在工作目录，直接使用kubectl apply：
kubectl apply -f ./kubefate_163.yaml
【注】如果你是删除了kubefate和ingress-ngnix重新执行这一步，可能会发生一个错误，解决办法参考：https://blog.csdn.net/qq_39218530/article/details/115372879
稍等一会，大概10几秒后用下面命令看下KubeFATE服务是否部署好：
kubectl get all,ingress -n kube-fate
可能的问题会导致kubefate pod crash：
Startup probe failed: Get "http://10.244.1.34:8080/": dial tcp 10.244.1.34:8080: connect: connection refused
如果返回类似下面的信息（特别是pod的STATUS显示的是Running状态），则KubeFATE的服务就已经部署好并正常运行：
[root@harbor kubefate]# kubectl get all,ingress -n kube-fate

ingress.networking.k8s.io/kubefate nginx example.com 10.6.17.106 80 3d1h
.添加example.com到hosts文件
因为我们要用 example.com 域名来访问KubeFATE服务（该域名在ingress中定义，有需要可自行修改），需要在运行kubefate命令行所在的机器配置hosts文件（注意不是Kubernetes所在的机器，而是ingress-ngnix所在的机器，前面安装ingress-ngnix部分有讲）。 另外下文中部署的FATE集群默认也是使用example.com作为默认域名， 如果网络环境有域名解析服务，可配置example.com域名指向master机器的IP地址，这样就不用配置hosts文件。（IP地址一定要换成你自己的）
sudo -- sh -c "echo \"10.6.17.106 example.com\" >> /etc/hosts"
[root@harbor kubefate]# ping example.com
PING example.com (10.6.17.106) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.041/0.048/0.054/0.007 ms
使用vi修改config.yaml的内容。只需要修改serviceurl: example.com:31872加上映射的端口，如果忘记了重新查看一下80端口对应的映射端口：
[root@harbor kubefate]# kubectl -n ingress-nginx get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
ingress-nginx-controller LoadBalancer 10.1.130.161 10.6.17.106 80:32415/TCP,443:32491/TCP 3d19h
ingress-nginx-controller-admission ClusterIP 10.1.78.36 443/TCP 3d19h
修改完成查看一下，显示如下：
[root@harbor kubefate]# kubefate version
* kubefate commandLine version=v1.4.4
* kubefate service version=v1.4.4
使用KubeFATE安装FATE
按照前面的计划，我们需要安装3联盟方，ID分别9998、9999与10000。现实情况，这3方应该是完全独立、隔绝的组织，为了模拟现实情况，所以我们需要先为他们在Kubernetes上创建各自独立的命名空间(namespace)。 我们创建命名空间fate-9998用来部署9998，fate-9999用来部署9999，fate-10000部署10000
kubectl create namespace fate-9998
kubectl create namespace fate-9999
kubectl create namespace fate-10000
在exmaple目录下，预先设置了3个例子：/kubefate/examples/party-9998/和/kubefate/examples/party-9999/ 和 /kubefate/examples/party-10000 对于/kubefate/examples/party-9999/cluster.yaml，我们可以将其修改如下：

安装FATE集群
如果一切没有问题，那就可以使用kubefate cluster install来部署两个fate集群了，（没遇到坑的步骤按照官方的执行就可以）
kubefate cluster install -f ./examples/party-10000/cluster10000.yaml
kubefate cluster install -f ./examples/party-9999/cluster9999.yaml
kubefate cluster install -f ./examples/party-9998/cluster9998.yaml
这时候，KubeFATE会创建3个任务去分别部署两个FATE集群。我们可以通过kubefate job ls来查看任务，或者直接watch KubeFATE中集群的状态，直至变成Running
[root@harbor kubefate]# watch kubefate cluster ls
UUID NAME NAMESPACE REVISION STATUS CHART ChartVERSION AGE
7bca70c1-236c-4931-81f8-1350cce579d4 fate-9998 fate-9998 1 Running fate v1.8.0 18m
143378db-b84d-4045-8615-11d36335d5b2 fate-9999 fate-9999 0 Creating fate v1.8.0 17m
d3e27a39-c8de-4615-96f2-29012f3edc68 fate-10000 fate-10000 0 Creating fate v1.8.0 17m
因为这个步骤需要到网易云镜像仓库去下载约10G的镜像，所以第一次执行视乎你的网络情况需要一定时间（耐心等待上述下载过程，直至状态变成Running）。 检查下载的进度可以用
kubectl get po -n fate-9998
kubectl get po -n fate-9999
kubectl get po -n fate-10000
全部的镜像下载完成后，结果会呈现如下样子：
[root@harbor kubefate]# kubectl get po -n fate-9998

验证FATE的部署
通过以上的 kubefate cluster ls 命令, 我们得到 fate-9998 的集群ID是 7bca70c1-236c-4931-81f8-1350cce579d4, fate-9999 的集群ID是 143378db-b84d-4045-8615-11d36335d5b2, 而 fate-10000 的集群ID是 d3e27a39-c8de-4615-96f2-29012f3edc68. 我们可以通过kubefate cluster describe查询集群的具体访问信息：
[root@harbor kubefate]# kubefate cluster describe 7bca70c1-236c-4931-81f8-1350cce579d4

从返回的内容中，我们看到Info->dashboard里包含了:
- Jupyter Notebook的访问地址： party9998.notebook.example.com。这个是我们准备让数据科学家进行建模分析的平台。已经集成了FATE-Clients；
- FATEBoard的访问地址： party9998.fateboard.example.com。我们可以通过FATEBoard来查询当前训练的状态。
同样的查看 fate-10000的信息，可以看到 dashboard的网址虽然不同，但是ip都是10.6.17.106，也就是ingress-ngnix的地址，所以即使是访问party10000.fateboard.example.com，也是先访问10.6.17.106，而不是fate-10000所在的主机10.6.17.104。
在浏览器访问FATE集群的机器上配置相关的Host信息
如果是Windows机器，我们需要把相关域名解析配置到C:\WINDOWS\system32\drivers\etc\hosts：
10.6.17.106 party9998.notebook.example.com
10.6.17.106 party9998.fateboard.example.com
10.6.17.106 party9999.notebook.example.com
10.6.17.106 party9999.fateboard.example.com
10.6.17.106 party10000.notebook.example.com
10.6.17.106 party10000.fateboard.example.com
注意以上网址都是设置IP为10.6.17.106
用网址party10000.fateboard.example.com：32415，登陆party10000的fateboard，用户名和密码如下图：
问题：
1、过了1天，发现命名空间fate-9998和fate-10000对应的fateboard界面访问不了了，只有fate-9999的可以访问，经检查：
root@harbor kubefate]# kubectl get pods -n fate-9998

查看到python这个podCrashLoopBackOff，其内部由两容器fateboard和ping-mysql，查看其ping-mysql容器：
root@harbor kubefate]# kubectl logs -f python-594cd5c47b-vl4mb -n fate-9998 -c ping-mysql
得知mysql有问题，于是直接重新部署fate-9998的mysql：
kubectl rollout restart deployment mysql -n fate-9998
再重新部署fate-9998的python：
kubectl rollout restart deployment python -n fate-9998
