# 定義動作和引數的組態設定
<a name="custom-bootstrap-actions-config-v3"></a>

下列組態設定用於定義 [`HeadNode`](HeadNode-v3.md) / [`CustomActions`](HeadNode-v3.md#HeadNode-v3-CustomActions) / [`OnNodeStart`](HeadNode-v3.md#yaml-HeadNode-CustomActions-OnNodeStart) & [`OnNodeConfigured`](HeadNode-v3.md#yaml-HeadNode-CustomActions-OnNodeConfigured) & [`OnNodeUpdated`](HeadNode-v3.md#yaml-HeadNode-CustomActions-OnNodeUpdated)和 [`Scheduling`](Scheduling-v3.md) / [`OnNodeStart`](Scheduling-v3.md#yaml-Scheduling-SlurmQueues-CustomActions-OnNodeStart) & [`CustomActions`](Scheduling-v3.md#Scheduling-v3-SlurmQueues-CustomActions) [`OnNodeConfigured`](Scheduling-v3.md#yaml-Scheduling-SlurmQueues-CustomActions-OnNodeConfigured)動作和引數。

```
HeadNode:
  [...]
  CustomActions:
    OnNodeStart:
      # Script URL. This is run before any of the bootstrap scripts are run
      Script: s3://amzn-s3-demo-bucket/on-node-start.sh
      Args:
        - arg1
    OnNodeConfigured:
      # Script URL. This is run after all the bootstrap scripts are run
      Script: s3://amzn-s3-demo-bucket/on-node-configured.sh
      Args:
        - arg1
    OnNodeUpdated:
      # Script URL. This is run after the head node update is completed.
      Script: s3://amzn-s3-demo-bucket/on-node-updated.sh
      Args:
        - arg1

      CustomActions:
        OnNodeStart:

```

使用 `Sequence`設定 （在 3.6.0 AWS ParallelCluster 版中新增）：

```
HeadNode:
  [...]
  CustomActions:
    OnNodeStart:
      # Script URLs. The scripts are run in the same order as listed in the configuration, before any of the bootstrap scripts are run.
      Sequence:
        - Script: s3://amzn-s3-demo-bucket/on-node-start1.sh
          Args:
            - arg1
        - Script: s3://amzn-s3-demo-bucket/on-node-start2.sh
          Args:
            - arg1
        [...]
    OnNodeConfigured:
      # Script URLs. The scripts are run in the same order as listed in the configuration, after all the bootstrap scripts are run.
      Sequence:
        - Script: s3://amzn-s3-demo-bucket/on-node-configured1.sh
          Args:
            - arg1
        - Script: s3://amzn-s3-demo-bucket/on-node-configured2.sh

          Args:
            - arg1
        [...]
  # Bucket permissions
  Iam:
    S3Access:
      - BucketName: bucket_name
        EnableWriteAccess: false
Scheduling:
  Scheduler: slurm
   [...]
  SlurmQueues:
    - Name: queue1
      [...]
      CustomActions:
        OnNodeStart:
          # Script URLs. The scripts are run in the same order as listed in the configuration, before any of the bootstrap scripts are run
          Sequence:
            - Script: s3://amzn-s3-demo-bucket/on-node-start1.sh
              Args:
                - arg1
            - Script: s3://amzn-s3-demo-bucket/on-node-start2.sh
              Args:
                - arg1
            [...]
        OnNodeConfigured:
          # Script URLs. The scripts are run in the same order as listed in the configuration, after all the bootstrap scripts are run
          Sequence:
            - Script: s3://amzn-s3-demo-bucket/on-node-configured1.sh
              Args:
                - arg1
            - Script: s3://amzn-s3-demo-bucket/on-node-configured2.sh
              Args:
                - arg1
            [...]
      Iam:
        S3Access:
          - BucketName: bucket_name
            EnableWriteAccess: false
```

從 3.6.0 AWS ParallelCluster 版開始新增`Sequence`設定。當您指定 時`Sequence`，您可以列出自訂動作的多個指令碼。 AWS ParallelCluster 繼續支援使用單一指令碼設定自訂動作，而不包含 `Sequence`。

AWS ParallelCluster 不支援同時包含單一指令碼和`Sequence`相同的自訂動作。例如，如果您指定下列組態，則 AWS ParallelCluster 失敗。
