`docker-compose up` 与带环境变量的 `docker compose up`

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 ACI 文档中的 this example from the Elasticsearch documentation and 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，出现错误，因为它没有从 .env 文件:

> 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

有没有办法在使用 docker compose 或使用 docker-compose 时加载 .env 文件？我不完全理解 docker compose 命令的来源以及为什么它与 docker-compose 不同，它似乎不是我能看到的标准 docker 命令或 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。

基于 this GitHub issue comment, it seems that docker-compose is the original Compose project, its source code lives in the docker/compose 存储库。

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

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