不支持docker-compose中的版本 [英] Version in docker-compose is unsupported

问题描述

我尝试安装此 docker-compose配置。如您所见，它具有版本3。
当我使用 docker-compose build --pull 运行它时，出现此错误：

I try to install this docker-compose configuration. As you can see, it has version 3. When I run this with docker-compose build --pull, I got this error:

ERROR: Version in "./docker-compose.yml" is unsupported. 
You might be seeing this error because you're using the wrong Compose file version. 
Either specify a version of "2" (or "2.0") and place your service definitions 
under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

如果我从.yml中删除了版本，则会出现这样的错误：

If I remove version from .yml, then I get such error:

ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for volumes: 'conf.d'
Unsupported config option for services: 'letsencrypt-companion'
Unsupported config option for networks: 'proxy-tier'

阅读文档后首先想到的是版本不兼容。所以我已经将docker更新为 17.9.1-ce 。

这是 docker-compose ：

After reading documentation my first thoughts was about version incompatibility. So I've updated docker to 17.9.1-ce.
And here is version of docker-compose:

docker-compose version 1.8.0, build unknown

但是错误是相同的，我对此一无所知。
操作系统：Ubuntu 17.10。

But errors are the same and I really have no idea about this. Operation System: Ubuntu 17.10.

推荐答案

您需要升级docker compose以及可能的docker引擎。 Docker compose 3.0文件需要Docker引擎1.13.0+版本（以及该版本的compose）。有关更多信息，请参见： https://docs.docker.com/compose/compose-file/ ，特别是Compose和Docker Engine兼容性列表。

You need to upgrade docker compose and possibly the docker engine. Docker compose 3.0 files require docker engine version 1.13.0+ (and that version of compose). For more information see: https://docs.docker.com/compose/compose-file/, specifically the Compose and Docker Engine compatibility matrix.

请注意，版本1.18.0在版本1.8.0之后。它是1.18.0版，而不是1.1.8.0版。次要版本号一直在增加（例如1.8.0-> 1.9.0-> 1.10.0-> 1.11.0）。

Please note that version 1.18.0 comes after versions 1.8.0. It's version 1.18.0, not version 1.1.8.0. The minor version number just keeps increasing (e.g. 1.8.0 -> 1.9.0 -> 1.10.0 -> 1.11.0).

最新版本（撰写本文时）为1.18，于2017年12月19日发布，1.8为2017年7月27日发布（ https://github.com/docker/compose/releases ）。您正在使用与docker-compose 3个文件不兼容的docker的旧版本。

The latest version (when writing this) is 1.18, released on December 19 2017, 1.8 was released on July 27 2017 (https://github.com/docker/compose/releases). You are using an old version of docker that is not compatible with docker-compose 3 files.

此外，它们更改了docker别名的编号以反映发布日期： 17.9.0是2017年9月版本（第一个数字是年份，第二个数字是月份）。

Also, they changed the numbering of the docker enigines to reflect the release date: 17.9.0 is the September 2017 release (first number is the year, second number is the month).
