`docker-compose up` 与 `docker compose up` 与环境变量

Question

我正在尝试使用 Docker Compose 将三节点 Elasticsearch 集群部署到 Azure 容器实例。我大致遵循 Elasticsearch 文档中的 this example 和 ACI 文档中的 this tutorial。

当我尝试使用我在大多数文档中看到的标准 docker-compose 命令部署到 ACI 时，我收到一条错误消息，指出它不受支持：

> docker-compose -f .\docker-compose.yml -f .\docker-compose.production.yml up
ERROR: The platform targeted with the current context is not supported.
Make sure the context in use targets a Docker Engine.

当我尝试使用 ACI 文档中的 docker compose（无连字符）命令部署到 ACI 时，我收到一个错误，因为它没有从 .env 文件加载环境变量：

> docker compose -f .\docker-compose.yml -f .\docker-compose.production.yml up
1 error(s) decoding:

* error decoding 'Volumes[1]': invalid spec: certs:: empty section between colons

在使用docker compose 或将docker-compose 与ACI 一起使用时，有没有办法加载.env 文件？我不完全明白docker compose 命令的来源以及为什么它与docker-compose 不同，它似乎不是标准的docker 命令或我可以看到的CLI 扩展。

这些是相关文件：

我也尝试过使用env_file 属性，但docker compose 似乎忽略了它。

Answer 1

基于this GitHub issue comment，docker-compose 似乎是最初的 Compose 项目，其源代码位于 docker/compose 存储库中。

docker compose 是一个新项目，它实现了 Compose 规范并支持 ECS 和 ACI，但还不支持本地部署。它的源代码位于docker/compose-cli 存储库中。

根据this issue，docker compose 还不支持 .env 文件。
