minikube可以快速构建一个单节点k8s集群用于学习测试使用。
- 用户赋权，不要使用root用户
[root@localhost ~]# usermod -aG docker minik && newgrp docker
[root@localhost ~]# id minik
uid=1001(minik) gid=1001(minik) groups=1001(minik),996(docker)
- 下载安装最新版minikube
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
- 启动集群。 安装完成后使用
minikube start启动一个集群
[minik@localhost ~]$ minikube start
* minikube v1.24.0 on Centos 7.8.2003
* Using the docker driver based on existing profile
X The requested memory allocation of 2200MiB does not leave room for system overhead (total system memory: 2988MiB). You may face stability issues.
* Suggestion: Start minikube with less memory allocated: 'minikube start --memory=2200mb'
* Starting control plane node minikube in cluster minikube
* Pulling base image ...
- 安装kubectl后使用kubectl get po -A或直接使用
minikube kubectl -- get po -A直接与集群交互，为方便操作，可以顺便同时使用别名
alias kubectl="minikube kubectl --"
[minik@localhost ~]$ minikube kubectl -- get pods -A

- 查看集群信息
[minik@localhost ~]$ minikube kubectl cluster-info
Kubernetes control plane is running at https://192.168.49.2:8443
CoreDNS is running at https://192.168.49.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
