minikube1.9.2安装

minikube v1.9.2 安装

1、查看当前`centos`系统版本，并关闭防火墙

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.7.1908 (Core)
[root@localhost software]# systemctl stop firewalld
[root@localhost software]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

2、下载安装包并修改权限（没有办法只能墙或者按量付费模式购买海外主机将依赖下载到本地）

curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \
  && chmod +x minikube

3、将minikube安装到path中

sudo mkdir -p /usr/local/bin/
sudo install minikube /usr/local/bin/

4、查看minikube的版本信息

[root@localhost ~]# minikube version
minikube version: v1.9.2
commit: 93af9c1e43cab9618e301bc9fa720c63d5efa393
[root@localhost ~]#

5、安装docker

卸载旧版docker

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

配置docker仓库地址

$ sudo yum install -y yum-utils

$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

下载对应rpm安装包并本地安装及相关依赖（也是为了安装学习方便将docker安装包rpm通过yumdownloader下载到本地）

[root@localhost software]# yumdownloader --resolve  docker-ce docker-ce-cli containerd.io
[root@localhost software]# ls -l
total 142800
-rw-r--r--. 1 root root 24416076 Mar  2 23:19 containerd.io-1.2.13-3.1.el7.x86_64.rpm
-rw-r--r--. 1 root root 25697324 Mar 11 15:42 docker-ce-19.03.8-3.el7.x86_64.rpm
-rw-r--r--. 1 root root 41468684 Mar 11 15:42 docker-ce-cli-19.03.8-3.el7.x86_64.rpm
-rwxr-xr-x. 1 root root 54639377 Apr 30 09:26 minikube

6、本地安装docker-ce-19.03.8

[root@localhost software]# yum localinstall *.rpm -y  --nogpgcheck

7、离线下载对应kubernetes所需的镜像，下载后tag对应版本

docker tag 43940c34f24f k8s.gcr.io/kube-proxy:v1.18.0     
docker tag a31f78c7c8ce k8s.gcr.io/kube-scheduler:v1.18.0
docker tag d3e55153f52f k8s.gcr.io/kube-controller-manager:v1.18.0   
docker tag 74060cea7f70 k8s.gcr.io/kube-apiserver:v1.18.0
docker tag cdc71b5a8a0e kubernetesui/dashboard:v2.0.0-rc6
docker tag 80d28bedfe5d k8s.gcr.io/pause:3.2
docker tag 67da37a9a360 k8s.gcr.io/coredns:1.6.7
docker tag 303ce5db0e90 k8s.gcr.io/etcd:3.4.3-0
docker tag 3b08661dc379 kubernetesui/metrics-scraper:v1.0.2 
docker tag 4689081edb10 gcr.io/k8s-minikube/storage-provisioner:v1.8.1   
docker tag a90209bb39e3 k8s.gcr.io/echoserver:1.4

8、安装conntrack工具

yum localinstall conntrack-tools-1.4.4-5.el7_7.2.x86_64.rpm -y  --nogpgcheck

swap问题处理

[root@localhost ~]# sudo swapoff -a
[root@localhost ~]# systemctl list-units --type=swap --state=active

9、下载kubelet及kubeadm

使用海外机器确认kubernetes最新稳定的版本
[root@iZt4n21lluemt0kwt3ti8oZ software]# curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt
v1.18.2
[root@iZt4n21lluemt0kwt3ti8oZ software]# 

下载对应版本工具
wget https://storage.googleapis.com/kubernetes-release/release/v1.18.2/bin/linux/amd64/kubeadm
wget https://storage.googleapis.com/kubernetes-release/release/v1.18.2/bin/linux/amd64/kubelet
wget https://storage.googleapis.com/kubernetes-release/release/v1.18.2/bin/linux/amd64/kubectl

10、可以使用minikube start下载或将已下载文件拷贝到/root/.minikube/cache/linux/v1.18.0

[root@localhost software]# minikube start --driver=none --keep-context=true --download-only=true

下载目录
[root@localhost v1.18.0]# ls -l
total 200896
-rwxr-xr-x. 1 root root 39809024 Apr 30 21:52 kubeadm
-rwxr-xr-x. 1 root root 44023808 Apr 30 21:51 kubectl
-rw-r--r--. 1 root root 52884887 Apr 30 21:53 kubelet
[root@localhost v1.18.0]# pwd
/root/.minikube/cache/linux/v1.18.0
[root@localhost v1.18.0]# 

并同时拷贝到目录/usr/local/bin/下

处理cgroups问题

[root@localhost v1.18.0]# sed -i "s/cgroup-driver=systemd/cgroup-driver=cgroupfs/g" /etc/systemd/system/kubelet.service.d/10-kubeadm.conf
[root@localhost v1.18.0]# 
[root@localhost v1.18.0]# systemctl daemon-reload && systemctl restart kubelet

11、启动minikube

[root@localhost images]# minikube start --driver=none

12、使用minikube

[root@localhost ~]# kubectl get node
NAME                    STATUS   ROLES    AGE   VERSION
localhost.localdomain   Ready    master   57m   v1.18.2
[root@localhost ~]# kubectl get ns

kube-system   kube-controller-manager-localhost.localdomain   1/1     Running   1          57m
kube-system   kube-proxy-jdmcp                                1/1     Running   1          57m
kube-system   kube-scheduler-localhost.localdomain            1/1     Running   1          57m

[root@localhost ~]# 

13、安装minikube ingress

[root@localhost software]# ls
nginx-ingress-controller.tar.gz quay.io+kubernetes-ingress-controller+nginx-ingress-controller:0.26.1.tar
[root@localhost software]# docker load < quay.io+kubernetes-ingress-controller+nginx-ingress-controller\:0.26.1.tar

[root@localhost software]# docker tag 29024c9c6e70 quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.26.1
[root@localhost software]# minikube addons enable ingress
* The 'ingress' addon is enabled
[root@localhost software]# 

14、使用minikube dashboard查看可视化界面

将为dashboard添加外部访问代理

minikube addons list 查看
minikube addons enable dashboard
minikube addons disable dashboard

暴露端口方式
kubectl proxy --port=8080 --address='192.168.2.4' --accept-hosts='^.*' &

通过以下地址访问

http://192.168.2.4:8080/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/#/overview?namespace=default

15、部署postwoman

[root@localhost software]# tar -xzvf postwoman.tar.gz
