ECS：環境變量設置任務，但不存在於容器

我有一個任務定義，看起來像這樣：ECS：環境變量設置任務，但不存在於容器

> aws ecs describe-task-definition --task-definition ruby-on-rails-test 
{ 
    "taskDefinition": { 
     "status": "ACTIVE",

       },

       "volumesFrom": [] 
      } 
     ], 
     "revision": 5 
    } 
}

當容器啓動時，環境變量沒有設置。我從ecs容器中運行以下命令，從容器啓動失敗

[[email protected] docker]# docker run --name 46485594ffc4 accountId.dkr.ecr.us-east-1.amazonaws.com/ cf/rails:latest env 
PATH=/usr/local/bundle/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin 
HOSTNAME=0e0656e4e84c 
RUBY_MAJOR=2.3 
RUBY_VERSION=2.3.4 
RUBY_DOWNLOAD_SHA256=341cd9032e9fd17c452ed8562a8d43f7e45bfe05e411d0d7d627751dd82c578c 
RUBYGEMS_VERSION=2.6.12 
BUNDLER_VERSION=1.15.0 
GEM_HOME=/usr/local/bundle 
BUNDLE_PATH=/usr/local/bundle 
BUNDLE_BIN=/usr/local/bundle/bin 
BUNDLE_SILENCE_ROOT_WARNING=1 
BUNDLE_APP_CONFIG=/usr/local/bundle 
APP_HOME=/opt/cf/rails-app 
HOME=/root

任何想法爲什麼變量沒有被設置？

在此先感謝。

什麼是「46485594ffc4」？ – Robert

當你自己拍下一張圖片時，你錯過了AWS用來運行容器的漏洞。他設置了env vars，只是在其docker run。

你這樣做：

搬運工運行--name 46485594ffc4 accountId.dkr.ecr.us-east-1.amazonaws.com/cf/rails:latest ENV

在那裏，你對您配置的任務沒有任何關係。你只有你推送的圖像。

所以，從停止容器檢查環境變量，你應該先找到它：

docker ps -a

與容器ID

然後執行：

docker inspect ID

有你應該看到env vars。

PS：如果你想看到與容器發生什麼，檢查其日誌：docker logs ID

謝謝@羅伯特。不，我需要弄清楚爲什麼當docker檢查清楚地顯示它們已設置時，我的應用程序沒有收到環境變量。 – aeldaly
