Terraform AWS Batch 作业定义参数 (aws_batch_job_definition)

如何解决Terraform AWS Batch 作业定义参数 (aws_batch_job_definition)

我试图了解在启动 AWS Batch 作业时如何进行参数替换。我需要做的是为我的 AWS Batch 作业提供一个 S3 对象键。我还没有找到将参数传递给 Batch 作业的 Terraform 示例，而且我似乎无法让它工作。

aws_batch_job_definition 的文档包含以下示例：

bin/console cache:clear --env=prod_ldap

假设我希望将 resource "aws_batch_job_definition" "test" { name = "tf_test_batch_job_definition" type = "container" container_properties = <<CONTAINER_PROPERTIES { "command": ["ls","-la"],"image": "busybox","memory": 1024,"vcpus": 1,"volumes": [ { "host": { "sourcePath": "/tmp" },"name": "tmp" } ],"environment": [ {"name": "VARNAME","value": "VARVAL"} ],"mountPoints": [ { "sourceVolume": "tmp","containerPath": "/tmp","readOnly": false } ],"ulimits": [ { "hardLimit": 1024,"name": "nofile","softLimit": 1024 } ] } CONTAINER_PROPERTIES } 作为参数，以便在我通过 AWS Batch API 启动作业时指定其值。这是如何实现的？根据 VARNAME 资源的文档，有一个名为 aws_batch_job_definition 的参数。但是，这是一张地图，而不是我所期望的列表。此映射中给出的键和值是什么？

解决方法

aws_batch_job_definition.parameters link 上的 Terraform 文档目前非常稀少。

但是，通过在 AWS 中的现有作业上运行 aws batch describe-jobs --jobs $job_id，参数对象似乎需要一个地图：

{
    "jobs": [
        {
            "parameters": {},"container": {
                "image": "","command": []
            }
        }
    ]
}

因此，您可以使用 Terraform 定义带有地图变量的批处理参数，然后在批处理资源命令定义中使用 CloudFormation 语法，例如 Ref::myVariableKey，一旦提交 AWS 作业就会正确插入。示例：

variable "batch_params" {
  type  = map
  default = {
    bucketName = "defaultBucketName",}
}

resource "aws_batch_job_definition" "test" {
  name = "tf_test_batch_job_definition"
  type = "container"

  parameters = var.batch_params

  container_properties = <<CONTAINER_PROPERTIES
{
    "command": ["Ref::bucketName"],"image": "busybox","memory": 1024,"vcpus": 1,"volumes": [
      {
        "host": {
          "sourcePath": "/tmp"
        },"name": "tmp"
      }
    ],"environment": [
        {"name": "VARNAME","value": "VARVAL"}
    ],"mountPoints": [
        {
          "sourceVolume": "tmp","containerPath": "/tmp","readOnly": false
        }
    ],"ulimits": [
      {
        "hardLimit": 1024,"name": "nofile","softLimit": 1024
      }
    ]
}
CONTAINER_PROPERTIES
}
