ubuntu16.04安装minikube

使用原生包管理工具安装kubectl

1.更新 apt 包索引，并安装使用 Kubernetes apt 仓库所需要的包

sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl

2.下载 Google Cloud 公开签名秘钥，如果有网络问题的话，可以手动下载apt-key.gpg文件，然后将其改名并移动到/usr/share/keyrings/kubernetes-archive-keyring.gpg目录

sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg

3.添加 Kubernetes apt 仓库：

echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

如果报错，可以使用中科大的源

echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] http://mirrors.ustc.edu.cn/kubernetes/apt kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

4.更新 apt 包索引，使之包含新的仓库并安装 kubectl：

sudo apt-get update
sudo apt-get install -y kubectl

使用minikube在单机上启动一个K8S机器用于测试

https://github.com/kubernetes/minikube/releases/tag/v1.21.0

1.安装minikube

curl -LO https://github.com/kubernetes/minikube/releases/download/v1.21.0/minikube_1.21.0-0_amd64.deb
sudo dpkg -i minikube_1.21.0-0_amd64.deb

2.创建集群

minikube start

如果遇到The image ‘xxx’ was not found; unable to add it to cache的报错，可以使用如下命令

minikube start --image-mirror-country='cn'

删除集群

minikube delete

创建特定版本的集群

minikube start --kubernetes-version=v1.21.1

3.查看集群

kubectl get po -A
NAMESPACE              NAME                                        READY   STATUS    RESTARTS      AGE
kube-system            coredns-64897985d-9hqwg                     1/1     Running   0             20h
kube-system            etcd-minikube                               1/1     Running   0             20h
kube-system            kube-apiserver-minikube                     1/1     Running   0             20h
kube-system            kube-controller-manager-minikube            1/1     Running   0             20h
kube-system            kube-proxy-gzjgt                            1/1     Running   0             20h
kube-system            kube-scheduler-minikube                     1/1     Running   0             20h
kube-system            storage-provisioner                         1/1     Running   1 (20h ago)   20h
kubernetes-dashboard   dashboard-metrics-scraper-58549894f-sztfp   1/1     Running   0             132m
kubernetes-dashboard   kubernetes-dashboard-ccd587f44-bvdc9        1/1     Running   0             132m

minikube一些命令：K8s - Install Minikube in Linux

4.启动kubernetes-dashboard，需要在图形界面中

minikube dashboard

5.配置dashboard外网访问，address是你的运行minikube的机器ip，port是对外暴露的端口

kubectl proxy --port=10018 --address='192.168.xx.xx' --accept-hosts='^.*' &

此时就可以访问如下的网址来访问minikube dashboard

http://master:10018/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/#/workloads?namespace=_all

6.minikube使用ingress
