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节点的联邦学习Fate集群 v1.7.2(全网最细-解决N多坑)》:
https://blog.csdn.net/Acecai01/article/details/128253844?spm=1001.2014.3001.5502

集群配置信息

3节点配置信息如下图:
在这里插入图片描述

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,可能需要翻墙才能下载:
https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.3/deploy/static/provider/cloud/deploy.yaml
以上文件中有2个翻墙才能下载的镜像,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       <none>           <none>
ingress-nginx-admission-patch-hmgr5         0/1     Completed   1          2d23h   10.244.1.27   gpu-51       <none>           <none>
ingress-nginx-controller-6995ffb95b-m87gh   1/1     Running     0          2d18h   172.17.0.8    k8s-node02   <none>           <none>

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   <pending>     80:30428/TCP,443:30338/TCP   16m
ingress-nginx-controller-admission   ClusterIP      10.1.32.33    <none>        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   <none>        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: <?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
        <head>
                <title>404 - Not Found</title>
        </head>
        <body>
                <h1>404 - Not Found</h1>
                <script type="text/javascript" src="//wpc.75674.betacdn.net/0075674/www/ec_tpm_bcon.js"></script>
        </body>
</html>

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

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

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

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:

  1. 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;
  2. 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:
在这里插入图片描述

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
问题解决。
