简介: 云原生|kubernetes|多集群管理之kubeconfig文件配置和使用(定义,使用方法,合并管理多集群)(二)

四,kubeconfig文件的使用:


定义环境变量,这个环境变量非常非常重要    KUBECONFIG  它的值是这个kubeconfig文件的绝对路径就可以了,我把这个文件存放到了23服务器的/media 文件夹下了:

export KUBECONFIG=/media/bootstrap.kubeconfig

OK,现在就可以使用kubectl试试使用此kubeconfig文件连接192.168.217.23:8443 这个apiserver了(还是在23服务器上):

[root@node3 media]# kubectl get po -A
NAMESPACE     NAME                            READY   STATUS    RESTARTS   AGE
default       static-web-node3                1/1     Running   0          4h42m
kube-system   coredns-7ff77c879f-nsj95        1/1     Running   0          5h25m
kube-system   etcd-node3                      1/1     Running   0          5h25m
kube-system   kube-apiserver-node3            1/1     Running   0          5h25m
kube-system   kube-controller-manager-node3   1/1     Running   0          5h25m
kube-system   kube-flannel-ds-amd64-6cdl5     1/1     Running   0          5h25m
kube-system   kube-proxy-vdhzr                1/1     Running   0          5h25m
kube-system   kube-scheduler-node3            1/1     Running   0          5h25m
kube-system   storage-provisioner             1/1     Running   0          5h25m

证明连接没有问题,kubectl config view 可以查看当前使用的kubeconfig文件的大概信息,可以看到证书的详细信息是隐藏了,集群名称也是前面设置的my:

[root@node3 media]# kubectl config view
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://192.168.217.23:8443
  name: myminikube
contexts:
- context:
    cluster: myminikube
    user: minikube
  name: default
current-context: default
kind: Config
preferences: {}
users:
- name: minikube
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED

那么,把这个文件传到另一台服务器,例如192.168.217.24服务器上,此服务器上只安装了一个kubectl:

版本说明:

注意,kubectl我安装的版本是1.22.2,管理的集群minikube的版本是1.18.8,因此,最后有一个报警,说客户端和服务端版本最好相差1,否则会出问题。

192.168.217.23上面安装的minkube版本是1.18.8:

[root@node3 media]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

[root@node3 media]# kubectl get no
NAME    STATUS   ROLES    AGE     VERSION
node3   Ready    master   5h34m   v1.18.8

说明kubectl确实是客户端,192.168.217.24服务器上只需要安装一个kubectl就可以了。

23上,上传前面命令制作的kubeconfig文件到24根目录:

[root@node3 media]# scp bootstrap.kubeconfig 192.168.217.24:~/
root@192.168.217.24's password: 
bootstrap.kubeconfig                                                                                                                                                                                      100% 5482     1.5MB/s   00:00  

在24服务器上使用传来的文件(定义环境变量):

[root@node4 ~]# export KUBECONFIG=/root/bootstrap.kubeconfig
[root@node4 ~]# kubectl get po -A
NAMESPACE     NAME                            READY   STATUS    RESTARTS   AGE

kube-system   etcd-node3                      1/1     Running   0          5h38m

kube-system   kube-proxy-vdhzr                1/1     Running   0          5h38m
kube-system   kube-scheduler-node3            1/1     Running   0          5h38m
kube-system   storage-provisioner             1/1     Running   0          5h39m

OK了,现在只需要把上面这个环境变量写入/etc/profile文件内,以后集群开机后就只需要登录24服务器就可以进行集群管理工作了。那么,假如有多个集群呢?

这个就简单了,把每个集群的kubeconfig文件都统一放置到一个服务器内,比如我这个192.168.217.24服务器内,然后进行kubeconfig文件的合并。

五,kubeconfig文件的合并


现在有两个集群,一个是kubeadm安装的高可用四节点集群,vip为192.168.217.100,一个是minkube,IP地址为192.168.217.23

将kubeadm部署的集群的kubeconfig文件kubeadm-config放置到192.168.217.24服务器上,文件内容如下:

[root@node4 ~]# cat kubeadm-config

激活环境变量后,可以正常管理此高可用集群:

[root@node4 ~]# export KUBECONFIG=/root/kubeadm-config 
[root@node4 ~]# kubectl get po -A
NAMESPACE     NAME                                       READY   STATUS             RESTARTS         AGE

OK,开始kubeconfig文件的合并,两个文件同时写入环境变量,文件之间用 :隔离开就是合并啦:

export KUBECONFIG=/root/kubeadm-config:/root/bootstrap.kubeconfig

config view 可以读取环境变量后,将相关内容显示出来:

[root@node4 ~]# kubectl config view
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://192.168.217.100:6443
  name: kubernetes
- cluster:
    certificate-authority-data: DATA+OMITTED
    server: https://192.168.217.23:8443
  name: myminikube
contexts:
- context:
    cluster: myminikube
    user: minikube
  name: default
- context:
    cluster: kubernetes
    user: kubernetes-admin
  name: kubernetes-admin@kubernetes
current-context: kubernetes-admin@kubernetes
kind: Config
preferences: {}
users:
- name: kubernetes-admin
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED
- name: minikube
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED

OK,先看看在使用哪个集群:

1. [root@node4 ~]# kubectl config current-context
2. kubernetes-admin@kubernetes

对比这个输出,我们可以看到context的名字是kubernetes这个集群,也就是kubeadm部署的HA集群 ,下面的命令也验证了这一点。

[root@node4 ~]# kubectl get po -A
NAMESPACE     NAME                                       READY   STATUS    RESTARTS         AGE
kube-system   calico-kube-controllers-796cc7f49d-k586w   1/1     Running   2 (13m ago)      2d3h
kube-system   calico-node-7x86d                          1/1     Running   2 (13m ago)      2d3h
略略略

OK,通过 config use-context  也就是切换上下文的方式,切换kubectl管理集群:

1. [root@node4 ~]# kubectl config use-context default
2. Switched to context "default".

验证一哈,确实切换到minikube了:

[root@node4 ~]# kubectl get po -A
NAMESPACE     NAME                            READY   STATUS    RESTARTS   AGE
default       static-web-node3                1/1     Running   0          5h35m
kube-system   coredns-7ff77c879f-nsj95        1/1     Running   0          6h18m
kube-system   etcd-node3                      1/1     Running   0          6h18m
略略略

在切换到kubeadm部署的HA集群:

[root@node4 ~]# kubectl config use-context kubernetes-admin@kubernetes
Switched to context "kubernetes-admin@kubernetes".

验证,可以看到完美切换:

[root@node4 ~]# kubectl get po -A
NAMESPACE     NAME                                       READY   STATUS    RESTARTS         AGE

略略略

那么环境变量合并的方式对于目前来说是足够了,仅仅几个集群嘛,无所谓,爱谁谁了。如果达到几十个上百个集群,那么,还是需要通过命令来合并集群的kubeconfig文件了。

六,命令方式合并kubeconfig文件


这个方法比较简单,主要是确定合并方向,是把minikube的kubeconfig文件合并到HA的kubeconfig文件内,因此,将24服务器上的HAkubeconfig文件改名为two-cs-config, 然后将此文件传到minkube的服务器也就是192.168.217.23服务器上,在执行以下的三个命令将它的本地证书内嵌到kubeconfig文件内,在将此文件传到24服务器就,就可以正常使用了(命令会追加写入指定内容到kubeconfig文件内,不会覆盖)

mv kubeadm-config two-cs-config
[root@node3 mnt]# kubectl config set-cluster myminikube \
> --certificate-authority=/root/.minikube/ca.crt \
> --embed-certs=true \
> --server=${KUBE_APISERVER} \
> --kubeconfig=two-cs-config
Cluster "myminikube" set.
[root@node3 mnt]# kubectl config set-credentials minikube \
> --client-certificate=/root/.minikube/profiles/minikube/client.crt \
> --client-key=/root/.minikube/profiles/minikube/client.key \
> --embed-certs=true \
> --kubeconfig=two-cs-config
User "minikube" set.
[root@node3 mnt]# kubectl config set-context default \
> --cluster=myminikube \
> --user="minikube" \
> --kubeconfig=two-cs-config
Context "default" created.
[root@node3 mnt]# cat two-cs-config
