如何解决AWS 批量云形成 - “CannotPullContainerError”
我有一个包含 6 个资源的 AWS Batch POC 的云形成模板。
- 3 AWS::IAM::角色
- 1 AWS::Batch::ComputeEnvironment
- 1 AWS::Batch::JobQueue
- 1 AWS::Batch::JobDefinition
AWS::IAM::Role 具有策略“arn:aws:iam::aws:policy/AdministratorAccess”（为了避免问题。）
使用的角色：
- 1 进入 AWS::Batch::ComputeEnvironment
- 2 进入 AWS::Batch::JobDefinition
但即使使用策略“arn:aws:iam::aws:policy/AdministratorAccess”，我也会收到“CannotPullContainerError：来自守护进程的错误响应：获取 https://********.dkr.ecr。 eu-west-1.amazonaws.com/v2/: net/http: 请求在等待连接时被取消（Client.Timeout 在等待标题时超出）”，当我完成一项工作时。
免责声明：一切都是 FARGATE（计算环境和作业），而不是 EC2

进入AWS::Batch::JobQueue:ContainerProperties:ExecutionRoleArn 我对arn 进行了硬编码，因为如果写入!Ref BatchJobRole，我会收到一个错误。但这不是我提出这个问题的目的。
问题是如何避免“CannotPullContainerError: Error response from daemon: Get https://********.dkr.ecr.eu-west-1.amazonaws.com/v2/: net/ http：当我运行作业时，请求在等待连接时被取消（等待标头时超出了 Client.Timeout）”。
解决方法
听起来您无法从子网内部访问互联网。
确保：
- 有一个与您的 VPC 关联的互联网网关设备（如果没有，请创建一个 -- 即使您只是使用 nat-gateway 进行出口）
- 与您的子网关联的路由表有一条默认路由 (0.0.0./0) 到 Internet 网关或带有附加弹性 IP 的 nat 网关。
- 附加的安全组具有允许您的端口和协议的出站互联网流量 (0.0.0.0/0) 的规则。 （例如 80/http、443/https）
- 与子网关联的网络访问控制列表（网络 ACL）具有允许到互联网的出站和入站流量的规则。
