Question

我正在使用ci上的Maven liquibase插件运行数据库作业。我需要从AWS Parameter store中读取用户名，密码，dburl等参数，但是当我尝试将aws cli返回的值设置为自定义变量时，它始终为空/空。我知道该值存在，因为在MAC终端返回相同的命令的值。

我使用的是bash脚本job.When我在sh文件我看到的价值，但是当我赞同它在我的config.yml我看空白空值显示密码与圆CI安装AWS CLI。我也尝试使用AWS SSM与config.yml文件，但即使有值为空空来获取值。

我的Config.yml

echo "dbPassword = ${dbPassword}"

export dbPasswordDev=$dbPassword >> $BASH_ENV
echo $"Custom = $dbPasswordDev"

当我在env-set.sh中回显$ dbPasswordDev时，我看到了该值，但是在config.yml中却看不到该值，并且看到了空白/空字符串。此外，当我试图呼应与config.yml我希望看到，但是我看到了价值$ PASS空白空字符串

根据 their official documentation，您需要回显“导出foo = bar”到$ BASH_ENV（这只是在bash会话开始时运行的文件）：

在您的env-setup.sh文件中：

echo "export dbPasswordDev=$dbPassword" >> $BASH_ENV

这是更高级的情况，可以从.env文件中加载变量。

version: 2
aliases:

  - &step_process_dotenv
      run:
        name: Process .env file variables
        command: echo "export $(grep -v '^#' .env | xargs)" >> $BASH_ENV

jobs:
  build:
    working_directory: ~/project
    docker:
      - image: php
    steps:
      - checkout
      - *step_process_dotenv
