Centos下安装minikube

GitHub minikube

Kubernetes目前最高支持Docker版本17.03

 

Minikube是什么？

Minikube是一种方便在本地运行Kubernetes的工具. 
Minikube 是能够在VM中运行单节点的Kubernetes集群. 
Minikube是为了开发或测试在本地启动一个节点的kubernetes集群.

特色

不能启动生产集群，没有高可用性的单节点机器. 
能够工做在Windows,Linux,MacOS下.

先决条件

须要安装VirtualBox和Minikube

安装Minikube

• 安装minikube

1. $curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && chmod +x minikube && sudo mv minikube /usr/local/bin/

2. % Total % Received % Xferd Average Speed Time Time Time Current

3. Dload Upload Total Spent Left Speed

4. 100 82.3M 100 82.3M 0 0 4295k 0 0:00:19 0:00:19 --:--:-- 4896k

• 安装kubectl

1. $curl -Lo kubectl https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl && chmod +x kubectl

2. % Total % Received % Xferd Average Speed Time Time Time Current

3. Dload Upload Total Spent Left Speed

4. 100 68.9M 100 68.9M 0 0 4756k 0 0:00:14 0:00:14 --:--:-- 5385k

5. $ sudo mv kubectl /usr/local/bin/

• 配置信息

1. $ export MINIKUBE_WANTUPDATENOTIFICATION=false

2. $ export MINIKUBE_WANTREPORTERRORPROMPT=false

3. $ export MINIKUBE_HOME=$HOME

4. $ export CHANGE_MINIKUBE_NONE_USER=true

5. $ mkdir $HOME/.kube || true

6. $ touch $HOME/.kube/config

7. $ export KUBECONFIG=$HOME/.kube/config

启动Minikube

1. $ minikube start --vm-driver=virtualbox

2. Starting local Kubernetes v1.7.0 cluster...

3. Starting VM...

4. Downloading Minikube ISO

5. 97.80 MB / 97.80 MB [==============================================] 100.00% 0s

6. Getting VM IP address...

7. Moving files into cluster...

8. Setting up certs...

9. Starting cluster components...

10. Connecting to cluster...

11. Setting up kubeconfig...

12. Kubectl is now configured to use the cluster.

1.  

2. $ kubectl get nodes

3. NAME STATUS AGE VERSION

4. minikube Ready 5s v1.7.0

1.  

2. $ kubectl get pods --all-namespaces

3. NAMESPACE NAME READY STATUS RESTARTS AGE

4. kube-system kube-addon-manager-minikube 1/1 Running 0 2h

5. kube-system kube-dns-910330662-pkvj6 3/3 Running 0 2h

6. kube-system kubernetes-dashboard-mg5jt 1/1 Running 0 2h

若是minikube启动提示没有找到VboxManage，能够参考Github上的方法：

此参数告诉Kubernetes组件运行在主机上，而非VM虚拟机上。

若是运行在VM上，Docker只须要VM的驱动程序，而非管理程序。使用主机模式，请确保Docker的网络链接模拟为桥接（bridge network）。

一、查看已安装的Docker版本

$ yum list installed | grep docker

二、卸载已安装的Docker版本

yum -y remove docker-ce.x86_64
