Docker 未读取 .env 文件

问题描述 投票：0回答：1

我正在尝试使用 Docker Compose 设置 Elastic Stack。作为背景，我在安装了 WSL2 和 Docker Desktop（Docker Compose 版本 v2.20.2-desktop.1）的 Windows 10 设备上运行。我已使用 

sysctl -w vm.max_map_count=262144
命令更改了虚拟内存配置。

我在目录

C:\Project Root\esk
中创建了两个文件。第一个是我的 
docker-compose.yaml
文件，另一个是我的 
.env
文件。当我运行 
docker-compose up -d
命令时，每个环境变量都会出现错误，表示未设置。错误如下：

time="2023-08-14T23:04:47+10:00" level=warning msg="The \"STACK_VERSION\" variable is not set. Defaulting to a blank string."

parsing C:\root\esk\docker-compose.yaml: error while interpolating services.kibana.mem_limit: failed to cast to expected type: invalid size: ''

这是我的 .env 文件：

ELASTIC_PASSWORD=password
KIBANA_PASSWORD=password
STACK_VERSION=8.4.3
CLUSTER_NAME=docker-cluster
LICENSE=basic
ES_PORT=9200
KIBANA_PORT=5601

XPACK_REPORTING_ENCRYPTIONKEY=9h72FEdcxf0OvDsmkCZzhl5psPT1hoj1

这是我的 docker-compose.yaml：

我尝试过删除换行符、引用变量、重新启动计算机、重新安装 docker、以管理员身份运行、更改我的系统区域设置（我最初是日语区域设置），但没有任何效果。有时，当我尝试运行它时 - 即使没有对 .env 文件进行更改 - 它只会给出某些变量的错误，而不会给出其他变量的错误。看起来很随意。

docker docker-compose elastic-stack docker-desktop .env

我在尝试使用

docker-compose
参考官方弹性页面elk-docker-compose

设置ELK时遇到了同样的问题

上述错误主要是因为系统无法读取

.env
文件，请正确检查您是否存储了带有
.env
扩展名的文件而不是
.env.txt
扩展名的文件。
