2.8、部署测…

kubeadm、kubelet、kubectl、docker-ce

CentOS7.5

kubeadm、kubelet、kubectl、docker-ce

CentOS7.5

kubeadm、kubelet、kubectl、docker-ce

注意所有主机配置推荐CPU2C

/^SELINUX/s/enforcing/disabled/

/etc/selinux/config配置主机名并绑定hosts不同主机名称不同

[rootlocalhost

192.168.200.113:/etc/[rootlocalhost

~]#

net.bridge.bridge-nf-call-ip6tables

net.bridge.bridge-nf-call-iptables

EOF

/etc/yum.repos.d/CentOS-Base.repo

http://mirrors.aliyun.com/repo/Centos-7.repo

[rootk8s-master

https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo[rootk8s-master

~]#

https://nyakyfun.mirror.aliyuncs.com

END

kubeadm安装工具使所有的组件都会以容器的方式运行kubectl客户端连接K8S

2.2、配置阿里云yum源

/etc/yum.repos.d/kubernetes.repo

[kubernetes]

baseurlhttps://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/

enabled1

gpgkeyhttps://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpghttps://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg

EOF[rootk8s-master

中的也可将这些配置写入配置文件方便管理复杂的配置项。

Kubeadm

kubeadm

定于为192.168.147.137通过如下指令创建默认的init-config.yaml文件

[rootk8s-master

system:bootstrappers:kubeadm:default-node-tokentoken:

registry.aliyuncs.com/google_containers/coredns:1.7.0[rootk8s-master

~]#

文件。

这里是将在初始化时[kubeconfig]步骤生成的admin.conf

拷贝到.kube/config

通过初始化安装是不包括网络插件的也就是说初始化之后是不具备相关网络功能的比如

k8s-master

sha256:db9458ca9d8eaae330ab33da5e28f61778515af2ec06ff14f79d94285445ece9

[rootk8s-master

和Master的连接还不正常。

目前最流行的Kubernetes

网络插件有Flannel、Calico、Canal、Weave

所有主机上传flannel_v0.12.0-amd64.tar、cni-plugins-linux-amd64-v0.8.6.tgz

[rootk8s-master

cni-plugins-linux-amd64-v0.8.6.tgz

[rootk8s-master

nginx:1.19.6在Kubernetes集群中创建一个pod验证是否正常运行。

/opt/pgmonitor将下载yaml包上传至/opt/pgmonitor目录并解压

[rootk8s-master

k8s-prome***us-grafana-master.zip

3.2、部署prome***us

k8s-prome***us-grafana-master]#

kubectl

进入/opt/pgmonitor/k8s-prome***us-grafana-master/prome***us目录

[rootk8s-master

k8s-prome***us-grafana-master]#

prome***us

部署rbac、部署configmap.yaml、部署prome***us.deploy.yml、部署prome***us.svc.yml

[rootk8s-master

进入/opt/pgmonitor/k8s-prome***us-grafana-master/grafana目录

[rootk8s-master

5m12s通过浏览器访问grafanahttp://[masterIP]:[grafana端口]

例如http://192.168.200.111:31191默认的用户名和密码admin/admin
