Centos下安裝minikube

GitHub minikube

Kubernetes目前最高支持Docker版本17.03

 

Minikube是什麼？

Minikube是一種方便在本地運行Kubernetes的工具. 
Minikube 是能夠在VM中運行單節點的Kubernetes集羣. 
Minikube是爲了開發或測試在本地啓動一個節點的kubernetes集羣.

特色

不能啓動生產集羣，沒有高可用性的單節點機器. 
能夠工做在Windows,Linux,MacOS下.

先決條件

須要安裝VirtualBox和Minikube

安裝Minikube

• 安裝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

• 安裝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

啓動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啓動提示沒有找到VboxManage，能夠參考Github上的方法：

此參數告訴Kubernetes組件運行在主機上，而非VM虛擬機上。

若是運行在VM上，Docker只須要VM的驅動程序，而非管理程序。使用主機模式，請確保Docker的網絡鏈接模擬爲橋接（bridge network）。
