使用docker和ngnix的AWS ECS，如何讓我的nginx配置進入容器？

Question

我想使用Nginx，獨角獸和Django在AWS中設置ECS羣集。

我已經將我的docker-compose.yml轉換爲ECS任務，但是想知道如何讓我的nginx配置進入容器？

這是我在JSON

我已經創建了文件的一些掛載點，但我不能確定如何獲得配置有任務。 當我從本地服務器運行docker時，nginx配置文件對於撰寫文件是本地的，顯然在aws中它不是？

如何通過ecs將nginx配置導入到包含中？

upstream web {

server { 
    location /static/ {  
     autoindex on;  
     alias /static/; 
    } 
    location/{

     proxy_set_header Host $http_host; 
     proxy_pass http://web/;

    listen 8000; 
    server_name localhost; 
}

據我所知（通過寫這個的時候），沒有「直接」的方式注入配置成在ECS容器比使用環境變量等。

儘管如此，這裏有一些事情可以做：

1. 使用AWS CLI從S3獲得Nginx的配置。

2. 將分佈式鍵值存儲（如etcd或Consul）部署到您的ECS羣集，然後存儲和檢索您需要的所有配置。這些工具通常用於共享配置和服務發現。如果你打算在你的環境中使用ECS，這可能是一個好主意。例如，關於nginx，您可以設置nginx + consul + registrator + consul模板，通過更新Consul中的nginx配置來自動重新加載容器內的nginx配置。 Here就是一個例子。

嘛，只是說...我希望有一天AWS提供類似ConfigMap和Secrets可在Kubernetes。在Kubernetes，這將是作爲simples爲：要kubectl create configmap nginx-configmap --from-file=nginx.conf

定義您波德定義（如您的「精英任務定義」）：

1. nginx的配置添加到Kubernetes集羣Kubernetes注入配置到您的容器：

volumeMounts: - name: nginx-config-volume mountPath: /etc/nginx ... volumes: - name: nginx-config-volume configMap: name: nginx-configmap

就是這樣！
