Azure云计算教程 - 在Azure App Service上部署容器化的Node.js应用

创建Node.js APP

bash

npx express-generator lcApp --view ejs
cd lcApp
npm i
npm start

这时就可以通过3000端口来测试这个APP了。

容器化这个应用

创建Dockerfile

docker

FROM node:alpine
COPY . . 
RUN npm install
CMD ["npm", "start"]

创建ACR

运行如下命令创建Azure Container Registry：

bash

az acr create --resource-group test --name lcacrnodeappdemo --location uksouth --admin-enabled --sku Basic --public-network-enabled true

这个过程很快，返回的结果类似于：

json

{
  "adminUserEnabled": true,
  "anonymousPullEnabled": false,
  "creationDate": "2023-03-10T22:44:27.018121+00:00",
  "dataEndpointEnabled": false,
  "dataEndpointHostNames": [],
  "encryption": {
    "keyVaultProperties": null,
    "status": "disabled"
  },
  "id": "/subscriptions/xxxxxxxxxxxxxx/resourceGroups/xxxxxx/providers/Microsoft.ContainerRegistry/registries/lcacrnodeappdemo",
  "identity": null,
  "location": "uksouth",
  "loginServer": "lcacrnodeappdemo.azurecr.io",
  "name": "lcacrnodeappdemo",
}

进入Azure Portal，ACR，Access Keys，记录下来用户名和密码，下一步需要用到。

登录ACR

输入如下命令登录Docker容器：

bash

docker login lcacrnodeappdemo.azurecr.io
Username: lcacrnodeappdemo
Password: 
WARNING! Your password will be stored unencrypted in /home/ubuntu/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

在本地构建Docker镜像

bash

docker build -t lcacrnodeappdemo.azurecr.io/test:latest .

验证已经成功创建镜像：

bash

> docker images

REPOSITORY                         TAG       IMAGE ID       CREATED         SIZE
lcacrnodeappdemo.azurecr.io/test   latest    137dbeeb4880   1 hours ago    179MB

将镜像推送到ACR

bash

docker push lcacrnodeappdemo.azurecr.io/test:latest

这时进入Azure Portal，就能在ACR，Repositories中看到新创建的镜像。

创建App Service Plan

bash

az appservice plan create --name TestNodeAppServicePlan --resource-group test --is-linux --sku B1

创建App Service

bash

az webapp create --name LcTestNodeApp --plan TestNodeAppServicePlan --resource-group test --deployment-container-image-name lcacrnodeappdemo.azurecr.io/test:latest

删除Resource Group

最后不要忘记删除这个Resource Group及组中所有资源。

bash

az group delete -n test
