Connection拒絕嘗試在docker中連接SpringBoot應用程式-有解無憂

我嘗試在 Docker、Circle CI 中運行 spring boot 應用程式。請檢查我的 .circleci/config.yml 檔案的樣子：

version: 2.1

jobs:

  test:
    docker:
      - image: maven:3.8.5-openjdk-17-slim

    environment:
      CHROMEDRIVER_VERSION: 100.0.4896.60
      CHROMEDRIVER_DIR: /tmp/chromedriver/
      WIKI_ENV: CIRCLE_CI

    steps:
      - checkout
      - run:
          name: "Install gnupg2, wget, xvfb and unzip"
          command: |
            apt-get update
            apt-get install -y gnupg2
            apt-get install -y wget xvfb unzip
      - run:
          name: "Install Chrome Browser"
          command: |
            wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
            echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list
            apt-get update -y
            apt-get install -y google-chrome-stable
      - run:
          name: "Setup chromedriver"
          command: |
            mkdir -p $CHROMEDRIVER_DIR
            wget -q --continue -P $CHROMEDRIVER_DIR "http://chromedriver.storage.googleapis.com/$CHROMEDRIVER_VERSION/chromedriver_linux64.zip"
            unzip $CHROMEDRIVER_DIR/chromedriver* -d $CHROMEDRIVER_DIR
            export PATH=$CHROMEDRIVER_DIR:$PATH
      - run:
          name: "Build jar"
          command: mvn clean package spring-boot:repackage
      - run:
          name: "Start"
          command: mvn spring-boot:start
      - run:
          name: "Check"
          command: curl http://localhost:8080

      - store_test_results:
          path: target/surefire-reports/junitreports

      - store_artifacts:
          path: target/surefire-reports/junitreports

      - store_artifacts:
          path: target/screenshots

workflows:
  default:
    jobs:
      - test

管道在“檢查”步驟中失敗并出現curl: (7) Failed to connect to localhost port 8080: Connection refused錯誤。

這是“開始”步驟的輸出：

當我在本地運行此命令時-它可以作業。當它在 CI 上執行時 - 它失敗了。我試圖解決的問題：

java -jar target/selenium.jar &在“開始”步驟上運行命令
運行mvn spring-boot:run &命令而不是“構建 jar”和“開始”步驟
運行nohup mvn spring-boot:run &命令而不是“構建 jar”和“開始”步驟
在“開始”步驟之后添加sleep 120步驟

你能告訴我我做錯了什么嗎？

uj5u.com熱心網友回復：

很確定你在服務器啟動之前就開始卷曲了，所以試著等待服務器啟動

- run:
    name: wait
    command: sleep 10

uj5u.com熱心網友回復：

轉移到 gitlab CI，問題不再實際。
