【问题描述】：
我正在尝试创建一个安装 puppet 和 aws puppet 模块的 cloudformation 模板。我可以使用 puppet 创建我的实例，定义安全组等，它似乎工作正常，但我也想安装 aws puppet 模块作为我的模板的一部分。 这是我的木偶实例的代码
"PuppetMasterInstance" : {
"Type" : "AWS::EC2::Instance",
"Metadata" : {
"AWS::CloudFormation::Init" : {
"config" : {
"packages" : {
"yum" : {
"puppet3" : [],
"puppet3-server" : [],
"ruby-devel" : [],
"gcc" : [],
"make" : [],
"rubygems" : []
},
"rubygems" : {
"json" : []
}
},
"files": {
"/etc/yum.repos.d/epel.repo": {
"source": "https://s3.amazonaws.com/cloudformation-examples/enable-epel-on-amazon-linux-ami",
"mode": "000644",
"owner": "root",
"group": "root"
},
"/etc/puppet/autosign.conf": {
"content": "*.internal\n",
"mode": "100644",
"owner": "root",
"group": "wheel"
},
"/etc/puppet/fileserver.conf": {
"content": "[modules]\n allow *.internal\n",
"mode": "100644",
"owner": "root",
"group": "wheel"
},
"/etc/puppet/puppet.conf": {
"content": {
"Fn::Join": [
"",
[
"[main]\n",
" logdir=/var/log/puppet\n",
" rundir=/var/run/puppet\n",
" ssldir=$vardir/ssl\n",
" pluginsync=true\n",
"[agent]\n",
" classfile=$vardir/classes.txt\n",
" localconfig=$vardir/localconfig\n"
]
]
},
"mode": "000644",
"owner": "root",
"group": "root"
},
"/etc/puppet/modules/cfn/manifests/init.pp": {
"content": "class cfn {}",
"mode": "100644",
"owner": "root",
"group": "wheel"
},
"/etc/puppet/modules/cfn/lib/facter/cfn.rb": {
"source": "https://s3.amazonaws.com/cloudformation-examples/cfn-facter-plugin.rb",
"mode": "100644",
"owner": "root",
"group": "wheel"
}
},
"services": {
"sysvinit": {
"puppetmaster": {
"enabled": "true",
"ensureRunning": "true"
}
}
}
}
}
},
"Properties": {
"InstanceType": {
"Ref": "InstanceType"
},
"SecurityGroups": [
{
"Ref": "PuppetGroup"
}
],
"ImageId": {
"Ref": "AmiID"
},
"KeyName": {
"Ref": "KeyName"
},
"UserData": {
"Fn::Base64": {
"Fn::Join": [
"",
[
"#!/bin/bash\n",
"yum update -y \n",
"/opt/aws/bin/cfn-init --region ",
{
"Ref": "AWS::Region"
},
" -s ",
{
"Ref": "AWS::StackName"
},
" -r PuppetMasterInstance ",
" --access-key ",
{
"Ref": "CFNKeys"
},
" --secret-key ",
{
"Fn::GetAtt": [
"CFNKeys",
"SecretAccessKey"
]
},
"\n",
"/opt/aws/bin/cfn-signal -e $? '",
{
"Ref": "PuppetMasterWaitHandle"
},
"'\n"
]
]
}
}
}
}
这很好，但是我想在安装 puppet 后执行以下命令：
"gem install aws-sdk-core",
"gem install retries",
"export AWS_ACCESS_KEY_ID=my_key",
"export AWS_SECRET_ACCESS_KEY=my_secret",
"puppet module install puppetlabs-aws"
我尝试在“files:”之前使用“commands:”标签，但模板失败了。我试图将代码放在“UserData”中：但它又失败了。我找不到有关模板中不同部分的执行顺序的信息，我认为失败是由于错误的执行顺序造成的（命令运行时未安装 puppet 和 ruby）。
任何帮助将不胜感激。

我没有时间写一个例子，但我的第一个例子是写一些明确等待安装的 shell 脚本。执行顺序是针对cloud-init，看这个答案stackoverflow.com/questions/34095839/…

感谢您的建议。我需要将所有内容都包含在我的模板中，并且我能想到的检查服务是否已安装的唯一方法是编写无限循环来检查服务是否正在运行，但是我想这会阻止模板的执行和整个事情最终将等待一个无限循环完成，而这又是等待安装服务打破循环......在安装实例包后必须有一种正确的方法来执行我的脚本...... .
