Question

我根据这篇文章设置了所有内容

https://aws.amazon.com/tw/blogs/apn/announcing-atlassian-bitbucket-support-for-aws-codedeploy/

这是我的环境：

实例（与amazon linux免费套餐）
- 安装了apache 2.4

安全小组
- 只有22（只有我的IP可以访问）和80端口打开

Iptables 停止了

设置了

2个角色 - 一个用于链接S3＆lt; - ＆gt;到位桶（附上自定义政策）
- 一个角色是部署组（附带AWSCodeDeployRole政策）

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "",
      "Effect": "Allow",
      "Principal": {
        "Service": "codedeploy.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

尝试部署的脚本是 https://s3.amazonaws.com/aws-codedeploy-us-east-1/samples/latest/SampleApp_Linux.zip

权限 / var / www / *由具有755权限的ec2-user拥有

代理 service codedeploy-agent status = AWS CodeDeploy代理作为PID 7200

运行

线索： 我的s3存储桶中有一些zip文件是为每次部署而上传的。

错误代码：HEALTH_CONSTRAINTS

任何人都知道部署失败的原因是什么？

update1 使用iam配置文件重新启动实例后，可以部署应用程序。但它仍然失败，当我点击查看事件时，有如下日志：

任何人有什么问题？

Answer 1

错误代码HEALTH_CONSTRAINTS表示失败的实例多于预期，这是由部署配置定义的。

有关部署失败原因的详细信息，请在部署控制台https://region.console.aws.amazon.com/codedeploy/home?region=region#/deployments上单击失败的deploymentID，然后它将重定向到部署详细信息页面，其中包含指定的所有实例部署，每行包含实例的生命周期事件。然后单击ViewEvents，如果有View Logs链接，则可以看到此实例部署失败的原因。

如果控制台没有足够的信息来满足您的需求，则可以在较少的/var/log/aws/codedeploy-agent/codedeploy-agent.log中找到该实例上的日志。它包含最近部署的日志。

Answer 2

这是因为codeDeploy通过命中实例来检查ec2实例的运行状况。在部署之前，您需要在实例上运行以下bash脚本并检查脚本是否有效。必须启动httpd服务。重新启动实例。

import sys
import RPi.GPIO as GPIO
import os
from time import sleep
import urllib2

DEBUG = 1
# Setup the pins we are connect to

#CONNECT OUT PIN 
co2pin = 16

#Setup API and delay
myAPI = ""
myDelay = 16 #how many seconds between posting data

GPIO.setmode(GPIO.BCM)
GPIO.setup(co2pin, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)


def Cotime(co2pin):
    co = 0  
    if (GPIO.input(co2pin) == True):
    co += 1
    return (str(co))


if __name__ == '__main__':
    baseURL = 'https://api.thingspeak.com/update?api_key=%s' % myAPI
    print baseURL

    while True:
    try:
        co = Cotime(co2pin)
        f = urllib2.urlopen(baseURL +"&field3=%s" % (co))
        print f.read()
        print 'Value Detected' +str(co)
        f.close()
        sleep(int(myDelay))
    except:
        print 'exiting.'
        break

Answer 3

这取决于您的部署配置，但基本上一个或多个部署失败。

HEALTH_CONSTRAINTS：部署失败的实例太多了   已在指定的实例运行状况约束中成功部署

http://docs.aws.amazon.com/codedeploy/latest/APIReference/API_ErrorInformation.html

检查deployment configuration settings。部署的总体失败/成功基于这些设置。试试CodeDeployDefault.AllAtOnce，然后根据需要拨入。

另外，请仔细检查AWS CodeDeploy Instance Health设置，尤其是minimum-healthy-hosts

Answer 4

您要求在appspec.yaml文件中安装的某个依赖项与httpd24-tools服务之间似乎存在冲突。

[stderr]Error: httpd24-tools conflicts with httpd-tools-2.2.31-1.8.amzn1.x86_64
[stderr]Error: httpd24 conflicts with httpd-2.2.31-1.8.amzn1.x86_64
[stdout] You could try using --skip-broken to work around the problem

因此，尝试解决依赖安装问题。您可以尝试在ec2上手动安装依赖项并找到解决此冲突的方法，当您解决它时，将解决方案带到appspec.yaml文件并通过代码部署安装依赖项。

AWS代码部署+ bitbucket =失败（错误代码HEALTH_CONSTRAINTS）
