• 环境变量注入

  在 Docker Compose 中，docker-compose.yml 可以直接读取 .env 文件里的环境变量，用于服务配置、端口、镜像标签等。

  • 使用默认的.env

  # cat .env
  REDIS_IMAGE="cloud.test.com/devops-public/redis:6.0.9"
  TOOLS_IMAGE="cloud.test.com/edge/debug-network-tools:v0.0.1"
  

• 使用指定的env文件

docker compose --env-file ./config/test.env up -d

• compose.yml 示例
