连接失败，试图在docker中连接spring引导应用程序

Question

我尝试在Docker, Circle CI中运行spring引导应用程序。请检查我的。circleci/config。Yml文件看起来像:

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"检查"中失败。step withcurl: (7) Failed to connect to localhost port 8080: Connection refusederror.

下面是"Start"的输出一步:

当我在本地运行这个命令-它工作。当它在CI上执行时，它失败了。我试图修复的:

1. 在"Start"上运行java -jar target/selenium.jar &命令。
2. 运行mvn spring-boot:run &命令代替"Build jar"时,"步骤
3. 运行nohup mvn spring-boot:run &命令代替"Build jar"时,"步骤
4. 在"开始"后添加sleep 120步骤

你能告诉我我做错了什么吗?

Answer 1

移动到gitlab CI，问题不再是实际的

Answer 2

很确定在服务器启动之前你就已经开始旋转了，所以尝试等待服务器启动

- run:
name: wait
command: sleep 10
