使用 EB CLI 管理 Elastic Beanstalk 環境

安裝 EB CLI 並設定您的專案目錄後，即可使用 EB CLI 建立 Elastic Beanstalk 環境、部署原始碼和組態更新，以及叫出日誌和事件。

EB CLI 會從所有成功的命令傳回零 (0) 結束代碼，而在遇到任何錯誤時，則傳回非零結束代碼。

下列範例使用名為 eb 的空白專案資料夾，該資料夾經 EB CLI 初始化以搭配範例 Docker 應用程式使用。

Eb create

如欲建立您的第一個環境，請執行 eb create 並依提示操作。若您的專案目錄具備原始碼，EB CLI 會將其封裝並部署至您的環境。否則，將使用範例應用程式。

~/eb$ eb create
Enter Environment Name
(default is eb-dev): eb-dev
Enter DNS CNAME prefix
(default is eb-dev): eb-dev
WARNING: The current directory does not contain any source code. Elastic Beanstalk is launching the sample application instead.

 -- Events -- (safe to Ctrl+C) Use "eb abort" to cancel the command.

您的環境可能需要幾分鐘才能就緒。環境建立時，請按 Ctrl+C 返回命令列。

Eb status

執行 eb status，檢視環境的目前狀態。若狀態為 ready，則可於 elasticbeanstalk.com 取得範例應用程式，且環境已準備好更新。

~/eb$ eb status

  Application name: elastic-beanstalk-example

Eb health

使用 eb health 命令，檢視您環境中執行個體的運作狀態資訊和整體環境的狀態。使用 --refresh 選項以互動方式檢視每 10 秒更新的運作狀態。

~/eb$ eb health

Eb events

使用 eb events 來檢視 Elastic Beanstalk 輸出的事件清單。

~/eb$ eb events
2015-06-29 23:21:09    INFO    createEnvironment is starting.
2015-06-29 23:21:10    INFO    Using elasticbeanstalk-us-east-2-EXAMPLE as Amazon S3 storage bucket for environment data.
2015-06-29 23:21:23    INFO    Created load balancer named: awseb-e-g-AWSEBLoa-EXAMPLE
2015-06-29 23:21:42    INFO    Created security group named: awseb-e-gbzqc3jcra-stack-AWSEBSecurityGroup-EXAMPLE
...

Eb logs

使用 eb logs 自您環境中的執行個體叫出日誌。根據預設，eb logs 會從第一個啟動的執行個體叫出日誌，並以標準輸出顯示。您可透過 --instance 選項指定執行個體 ID，取得特定執行個體的日誌。

--all 選項會叫出所有執行個體的日誌，並將其儲存至 .elasticbeanstalk/logs 底下的子目錄。

~/eb$ eb logs --all
Retrieving logs...
Logs were saved to /home/local/ANT/mwunderl/ebcli/environments/test/.elasticbeanstalk/logs/150630_201410
Updated symlink at /home/local/ANT/mwunderl/ebcli/environments/test/.elasticbeanstalk/logs/latest

Eb open

如欲在瀏覽器開啟您環境的網站，請使用 eb open：

~/eb$ eb open

在視窗化環境中，預設將以新視窗開啟瀏覽器。在終端機環境中，將使用諸如 w3m 的命令列瀏覽器 (如有)。

Eb deploy

環境建立並就緒後，即可使用 eb deploy 進行更新。

此命令更適用於部分原始碼的封裝與部署作業，因此在此範例中，我們在專案目錄使用下列內容來建立 Dockerfile：

~/eb/Dockerfile

FROM ubuntu:12.04

RUN apt-get update
RUN apt-get install -y nginx zip curl

RUN echo "daemon off;" >> /etc/nginx/nginx.conf
RUN curl -o /usr/share/nginx/www/master.zip -L https://codeload.github.com/gabrielecirulli/2048/zip/master
RUN cd /usr/share/nginx/www/ && unzip master.zip && mv 2048-master/* . && rm -rf 2048-master master.zip

EXPOSE 80

CMD ["/usr/sbin/nginx", "-c", "/etc/nginx/nginx.conf"]

此 Dockerfile 會部署 Ubuntu 12.04 的映像並安裝遊戲 2048。執行 eb deploy 將應用程式上傳至您的環境：

~/eb$ eb deploy
Creating application version archive "app-150630_014338".
Uploading elastic-beanstalk-example/app-150630_014338.zip to S3. This may take a while.
Upload Complete.
INFO: Environment update is starting.
 -- Events -- (safe to Ctrl+C) Use "eb abort" to cancel the command.

執行 eb deploy 時，EB CLI 會封裝您專案目錄的內容，並將其部署至您的環境。

Eb config

透過 eb config 命令查看您執行環境可用的組態選項：

~/eb$ eb config
ApplicationName: elastic-beanstalk-example
DateUpdated: 2015-06-30 02:12:03+00:00
EnvironmentName: elasticBeanstalkExa-env
SolutionStackName: 64bit Amazon Linux 2015.03 v1.4.3 running Docker 1.6.2
settings:
  AWSEBAutoScalingScaleDownPolicy.aws:autoscaling:trigger:
    LowerBreachScaleIncrement: '-1'
  AWSEBAutoScalingScaleUpPolicy.aws:autoscaling:trigger:
    UpperBreachScaleIncrement: '1'
  AWSEBCloudwatchAlarmHigh.aws:autoscaling:trigger:
    UpperThreshold: '6000000'
...

此命令會在文字編輯器顯示可用的組態選項清單。所示的許多選項都具備 null 值，這些並非預設值，且您能夠加以修改來更新環境中的資源。如需這些選項的詳細資訊，請參閱組態選項。

Eb terminate

若您目前已完成使用環境，請使用 eb terminate 終止。

~/eb$ eb terminate
The environment "eb-dev" and all associated instances will be terminated.

INFO: terminateEnvironment is starting.
