Kubernetes in Azure with openSUSE Leap 15 建立小記
OS: openSUSE Leap 15
Azure-cli: 2.0.42
最近要準備新的讀書會 kubernetes up and running
所以要來準備實做環境, 目前選定 Azure 的 AKS 服務
作法有兩種
- 使用 azure cloud shell
- 使用 azure cli
Cloud Shell 方式應該是最方便的
但是 azure cli 應該也要會使用
安裝 azure-cli
安裝 curl
# zypper install -y curl
匯入 rpm key
新增 Azure CLI 的 repo
# zypper addrepo --name 'Azure CLI' --check https://packages.microsoft.com/yumrepos/azure-cli azure-cli
Adding repository 'Azure CLI' ....................................................................................................[done]
Repository 'Azure CLI' successfully added
URI : https://packages.microsoft.com/yumrepos/azure-cli
Enabled : Yes
GPG Check : Yes
Autorefresh : No
Priority : 99 (default priority)
Repository priorities are without effect. All enabled repositories share the same priority.
安裝 azure-cli 套件
# zypper install --from azure-cli -y azure-cli
Building repository 'Azure CLI' cache ............................................................................................[done]
Loading repository data...
Reading installed packages...
Resolving package dependencies...
The following NEW package is going to be installed:
azure-cli
1 new package to install.
Overall download size: 20.7 MiB. Already cached: 0 B. After the operation, additional 135.5 MiB will be used.
Continue? [y/n/...? shows all options] (y): y
Retrieving package azure-cli-2.0.42-1.el7.x86_64 (1/1), 20.7 MiB (135.5 MiB unpacked)
Retrieving: azure-cli-2.0.42-1.el7.x86_64.rpm ........................................................................[done (1.2 MiB/s)]
Checking for file conflicts: .....................................................................................................[done]
(1/1) Installing: azure-cli-2.0.42-1.el7.x86_64 ..................................................................................[done]
檢查 az 版本
# az -v
azure-cli (2.0.42)
使用互動的方式登入 azure ( 現在已經不需要輸入機器碼, 直接驗證帳號就可以 )
> az login
Note, we have launched a browser for you to login. For old experience with device code, use "az login --use-device-code"
已在目前的瀏覽器工作階段開啟新視窗。
You have logged in. Now let us find all subscriptions you have access to...
接下來參考 AKS 的快速入門來建立 Kubernets
建立資源群組, 這邊使用日東, 因為一開始用 美東, 不知道為何都失敗...
> az group create --name sakanaK8s --location japaneast
建立 AKS 叢集
> az aks create --resource-group sakanaK8s --name myAKScluster --node-count 1 --generate-ssh-keys
安裝 kubectl
> az aks install-cli
Downloading client to /usr/local/bin/kubectl from https://storage.googleapis.com/kubernetes-release/release/v1.11.1/bin/linux/amd64/kubectl
Connection error while attempting to download client ([Errno 13] Permission denied: '/usr/local/bin/kubectl')
- 這邊失敗是因為我使用一般使用者, 對 /usr/local/bin 目錄沒有寫入權限
暫時性解法, 開啟 other 寫入權限, 然後等等再改回來
# chmod o+w /usr/local/bin/
> az aks install-cli
Downloading client to /usr/local/bin/kubectl from https://storage.googleapis.com/kubernetes-release/release/v1.11.1/bin/linux/amd64/kubectl
Please ensure that /usr/local/bin is in your search PATH, so the `kubectl` command can be found.
取得驗證資料
> az aks get-credentials --resource-group sakanaK8s --name myAKScluster
Merged "myAKScluster" as current context in /home/sakana/.kube/config
觀察一下 config
> cat ~/.kube/config
暫時性解法, 改回來/usr/local/bin 權限
# chmod o-w /usr/local/bin/
使用 kubectl 指令測試
> kubectl get nodes
NAME STATUS ROLES AGE VERSION
aks-nodepool1-26466856-0 Ready agent 19m v1.9.9
進行應用程式測試
建立 azure-vote.yaml
- 檔案的內容從快速入門上面複製
使用 kubectl apply 命令來執行應用程式
> kubectl apply -f azure-vote.yaml
deployment.apps/azure-vote-back created
service/azure-vote-back created
deployment.apps/azure-vote-front created
service/azure-vote-front created
可以使用 kubectl get service 來觀察相關資訊
> kubectl get service
可以觀察 azure-vote-front 的外部IP 來連線看應用程式測試的結果
刪除剛剛的應用程式
> kubectl delete -f azure-vote.yaml
deployment.apps "azure-vote-back" deleted
service "azure-vote-back" deleted
deployment.apps "azure-vote-front" deleted
service "azure-vote-front" deleted
刪除剛剛建立的叢集
> az aks delete --resource-group sakanaK8s --name myAKScluster
Are you sure you want to perform this operation? (y/n): y
又算往 kubernetes 前進一步了
~ enjoy it
