为选择性环境部署配置Bitbucket Pipeline

首先需要在Bitbucket中创建pipeline并为其添加相应的配置文件。可在pipeline配置文件中添加一个环境变量，指定要部署的环境。接下来，在pipeline脚本中根据该环境变量的值来判断部署的目标环境。此外，建议使用特定的文件命名约定，以便正确识别要部署的代码版本和目标环境。以下是示例代码：

pipelines:
  branches:
    master:
      - step:
          deployment: production
          script:
            - export ENVIRONMENT=production
            - deploy.sh
      - step:
          deployment: staging
          script:
            - export ENVIRONMENT=staging
            - deploy.sh
      - step:
          deployment: test
          script:
            - export ENVIRONMENT=test
            - deploy.sh
      - step:
          deployment: development
          script:
            - export ENVIRONMENT=development
            - deploy.sh

在deploy.sh脚本中，可以使用以下代码来判断部署的目标环境和部署的代码版本：

if [ $ENVIRONMENT = "production" ]; then
  # deploy production code
elif [ $ENVIRONMENT = "staging" ]; then
  # deploy staging code
elif [ $ENVIRONMENT = "test" ]; then
  # deploy test code
elif [ $ENVIRONMENT = "development" ]; then
  # deploy development code
else
  echo "Invalid environment specified: $ENVIRONMENT"
  exit 1
fi

这样，当提交代码时，Bitbucket会自动执行pipeline并根据指定的环境变量部署代码到指定的目标环境中。
