代码部署报告：“部署失败：没有主机成功”，同时从 S3 .zip 修订版部署到 EC2 实例

Question

我正在尝试使用托管在单独 EC2 实例中的 Jenkins 创建从 Bitbucket 到 aws EC2 实例的自动化 CI 工作流。

我创建并配置了所需的一切（IAM 角色、aws 客户端和代码部署代理），如下文所述：
https://pranavpshah.wordpress.com/configure-aws-codedeploy/

顺便说一句，所有实例都基于 ubuntu 并在私有 VPC 中运行，我正在部署一个 node.js 应用程序。

例如，每次我推送到 Bitbucket 存储库时，我都可以在 S3 存储桶中成功创建一个 .zip 版本。但在代码部署仪表板中，我得到“部署失败没有主机成功”。错误信息。

每次我启动该过程时，“进行中”状态都需要 5 分钟以上。

当部署过程以失败状态完成时，我检查了 /var/log/aws/codedeploy-agent/codedeploy-agent.log 文件，这是我得到的：

我是否在配置中遗漏了什么？
请问有什么帮助吗？

Answer 1

1. 我刚刚检查了部署 ID“d-FEPBDKJMC”的详细信息，似乎实例 ID 是“arn:aws:ec2:us-west-2:219450671821:instance/i-d796060e”而不是“arn:aws:ec2:us-west-2:219450671821:instance/i-348913ed”在您粘贴的主机代理日志中。所以可能应该检查正确实例上的日志。

2. 部署时跳过了所有生命周期事件，我怀疑主机代理根本没有拉取命令。由于您提到该实例在 VPC 下，请确保 Codedeploy 和 S3 端点已列入白名单（我们需要连接到这些端点进行部署）。这里还有一个关于 Codedeploy 与 VPC 合作的文档，请点击安全性：https://aws.amazon.com/codedeploy/faqs/。

Answer 2

您确定实例具有访问 S3 的角色吗？我错过了这一点，并且没有附加到我的实例的角色来访问 S3。
