Terraform local-exec执行耗时过长问题求助

配置代码 #

resource "null_resource" "example" {
  provisioner "local-exec" {
    command = <<EOT
      docker build -t imagename -f devops/Dockerfile .
      aws ecr get-login-password --region us-east-2 | docker login --username AWS --password-stdin xxxxx.dkr.ecr.us-east-2.amazonaws.com
      docker tag imagename:latest xxxxx.dkr.ecr.us-east-2.amazonaws.com/imagename:latest
      docker push xxxxx.dkr.ecr.us-east-2.amazonaws.com/imagename:latest
    EOT
    working_dir = "${path.module}/.."
  }
  depends_on = [
    aws_ecr_repository.example
  ]
}

resource "aws_instance" "example" {
  # ... instance configuration ...
  
  depends_on = [
    null_resource.example
  ]
}

需求说明 #

需先执行Docker镜像构建并推送至AWS ECR仓库，AWS实例需在null_resource执行完成后再创建。

当前问题 #

该null_resource已运行17分钟仍未结束，执行日志如下：

null_resource.example: Still creating... [30s elapsed]
null_resource.example: Still creating... [40s elapsed]
null_resource.example: Still creating... [50s elapsed]
null_resource.example: Still creating... [1m50s elapsed]
null_resource.example: Still creating... [2m50s elapsed]
null_resource.example: Still creating... [3m0s elapsed]
null_resource.example: Still creating... [4m0s elapsed]
null_resource.example: Still creating... [5m0s elapsed]
null_resource.example: Still creating... [6m0s elapsed]
null_resource.example: Still creating... [16m51s elapsed]
null_resource.example: Still creating... [17m1s elapsed]
null_resource.example: Still creating... [17m11s elapsed]

排查信息 #

• 在Windows10的Cmder中手动执行相同命令可正常完成，2.85GB的镜像仅需3分钟构建完成。
• null_resource已配置依赖ECR仓库，确保仓库创建完成后才执行推送。
• 移除null_resource后，Terraform可正常创建EC2实例和ECR仓库。
