使用AWS Cloud Formation安裝和調試軟件包的正確安裝方式
[英]Correct Way to Install & Debug Installation of Packages With AWS Cloud Formation
問題描述
我想用雲形成來設置我的基礎架構。 據我了解，有兩種安裝軟件包的方法。
選項1）帶包裝，例如
"packages": {
"apt-get": {
"epel-release": [],
"gcc-c++": [],
"make": [],
"git": []
}
}
選項2）有等待條件
"UserData": {
"Fn::Base64": {
"Fn::Join": [
"",
[
"#!/bin/bash -ex\n",
"apt-get update -y aws-cfn-bootstrap\n",
"apt-get install -y aws-cli\n",
...
現在，我的等待條件在安裝軟件包時超時。 到目前為止，我讀到了三個選項：
調試1）安裝失敗時發送錯誤
"npm install pm2 -g || error_exit 'Failed to install pm2.'\n",
調試2）成功執行步驟后發送正信號：
"/opt/aws/bin/cfn-signal -e 0 -r \"AWS installed node & npm.\" '",
調試3）檢查日志http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/troubleshooting.html
問題
問題1）我看不到調試1中提到的任何失敗消息，我該如何重寫模板，以確保這些消息正確顯示在事件中。
問題2）也許是因為它已經在第一步中失敗了。 但是我可以看到/使其可見，哪些子步驟已通過？
問題3）我在Mac上安裝了aws並為我的根帳戶運行aws configure 。 我如何從那里訪問日志。 因為EC2實例尚未運行，所以我不能只使用它。

我認為第二季度的答案是正在執行的CF堆棧的資源選項卡。 在“資源”選項卡上，您將看到已創建哪些資源，哪些正在進行中以及哪些失敗。 使用“ DependsOn”參數，我們可以強制執行創建資源的順序。 因此，您可以設置模板以按順序創建資源，並且可以查明故障（如果有）。
