Azure:容器未在预期时间内启动(WebApp) [英] Azure: Container did not start within expected time (WebApp)

问题描述

我在尝试部署 web 应用时遇到以下错误:

I'm getting the following error when trying to deploy a webapp:

错误 - 站点 XXX 的容器 XXX_0 未在预期时间限制内启动.经过时间 = 1800.4463925 秒

我正在尝试部署节点应用程序.使用带有 .deployment 文件的自动部署..deployment 文件如下所示:

I'm trying to deploy a node app. Using automatic deployment with a .deployment file. The .deployment file looks as follows:

# 1. KuduSync
if [[ "$IN_PLACE_DEPLOYMENT" -ne "1" ]]; then
  "$KUDU_SYNC_CMD" -v 50 -f "$DEPLOYMENT_SOURCE" -t "$DEPLOYMENT_TARGET" -n "$NEXT_MANIFEST_PATH" -p "$PREVIOUS_MANIFEST_PATH" -i ".git;.hg;
.deployment;deploy.sh"
  exitWithMessageOnError "Kudu Sync failed"
fi

# 2. Select node version
selectNodeVersion

# 3. Install npm packages for root directory
if [ -e "$DEPLOYMENT_TARGET/package.json" ]; then
  cd "$DEPLOYMENT_TARGET"
  # echo "Running $NPM_CMD install --production for root directory"
  # eval $NPM_CMD install --production
  echo "Running $NPM_CMD install --production for root directory"
  eval $NPM_CMD install
  exitWithMessageOnError "npm failed"
  ##################
  echo Building App...
  eval $NPM_CMD run build
  ##################
  echo Starting App...
  # eval $NPM_CMD run start
  # cd - > /dev/null
fi

#####################################################################################
echo "Finished successfully."

package.json 文件有以下脚本:

The package.json file has the following script:

  "scripts": {
    "dev": "node server.js",
    "build": "next build",
    "start": "echo 'work!!' && NODE_ENV=production && node server.js"
  }

而server.js如下:

And server.js is as follows:

const {
  createServer
} = require('http')
const next = require('next')
const app = next({
  dev: process.env.NODE_ENV !== 'production'
})
const routes = require('./routes')
const handler = routes.getRequestHandler(app)
console.log("HEYYYY");
// Without express
app.prepare()
  .then(() => {
    console.log("Ready on Localhost:80!!!");
    createServer(handler)
      .listen(80, (err) => {
        if (err) throw err;
        console.log("Ready on Localhost:80");
      });
  })

我从研究中收集到的是:

What I've gathered from research is that:

1. 应用启动时间不够
2. 端口未打开/未响应 启动时ping

为了解决 (1) 我将 WEBSITES_CONTAINER_START_TIME_LIMIT 设置为 1800(这是最大值)

To solve (1) I set WEBSITES_CONTAINER_START_TIME_LIMIT to 1800 (which is the max)

为了解决 (2) 我将 WEBSITES_PORT(在应用程序设置中)的值设置为80"以公开该端口.(根据文档)

To solve (2) I set WEBSITES_PORT (in app setting) with a value of "80" to expose that port. (As per documentation)

还有什么我应该尝试的吗?

Any others things I should try ?

PS 默认的 docker 日志文件输出如下:

PS the default docker log file outputs the following:

推荐答案

我在 Azure App Service Deploy 中同时设置 -Port 80 和 -WEBSITES_PORT 80 任务，azure devops 中的 App Settings 部分有所帮助.它使 docker 从端口 80 而不是 8000 开始.它位于 该任务的应用设置使用示例.

For me setting both -Port 80 and -WEBSITES_PORT 80 in Azure App Service Deploy task, App Settings section in azure devops helped. It made docker to start with port 80 instead of 8000. It is in example of app setting usage for that task.
