Question

我是Amazon Code Deploy的新手。我在部署

时遇到错误

部署失败
没有主机成功

我检查了Linux机器上的服务代码deploy-agent，它正在运行我该如何解决这个问题？

Answer 1

大多数情况下，由于Instance和CodeDeploy Service上的IAM权限不足而导致出现此问题。您需要检查/var/log/aws/codedeploy-agent/codedeploy-agent.log文件以获取详细信息。同样在/etc/codedeploy-agent/conf/codedeployagent.yml文件中，您可以设置:verbose: true以获取日志文件中的更多信息。

这些是您需要更新的IAM政策：

// Policy Role for Code Deploy
{
  "Version": "2012-10-17",
  "Statement": [
 {
  "Action": [
    "autoscaling:PutLifecycleHook",
    "autoscaling:DeleteLifecycleHook",
    "autoscaling:RecordLifecycleActionHeartbeat",
    "autoscaling:CompleteLifecycleAction",
    "autoscaling:DescribeAutoscalingGroups",
    "autoscaling:PutInstanceInStandby",
    "autoscaling:PutInstanceInService",
    "ec2:Describe*"
  ],
  "Effect": "Allow",
  "Resource": "*"
}
 ]
}

// Policy Trust for Code Deploy
{
  "Version": "2012-10-17",
  "Statement": [
{
  "Sid": "",
  "Effect": "Allow",
  "Principal": {
    "Service": [
      "codedeploy.us-west-2.amazonaws.com",
      "codedeploy.us-east-1.amazonaws.com"
    ]
  },
  "Action": "sts:AssumeRole"
}
 ]
}

// Instance Role for EC2 Instance
{ 
"Version": "2012-10-17", 
"Statement": [   
  {     
      "Action": [       
          "s3:Get*",       
          "s3:List*"     
      ],     
      "Effect": "Allow",     
      "Resource": "*"   
  } 
]
}

正如BrunoLevy所说，我们需要有关您尝试进行的部署的更多信息。

但是，作为调试的起点，您可以从部署页面中观察部署失败的步骤

您还可以查看主机上的Host Agent日志文件（/var/log/aws/codedeploy-agent/codedeploy-agent.log）。该文件包含有关部署的信息。

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。

    #!/bin/bash
    sudo su
    yum update -y
    yum install httpd -y
    yum install ruby
    yum install aws-cli
    cd ~
    aws s3 cp s3://aws-codedeploy-us-east-1/latest/install . --region us-east-1
    chmod +x ./install auto
    ./install auto
    echo 'hello world' > /var/www/html/index.html
    hostname >> /var/www/html/index.html
    chkconfig httpd on
    service httpd start
