用于定义操作和参数的配置设置

以下配置设置用于定义 HeadNode/CustomActions/OnNodeStart、OnNodeConfigured、OnNodeUpdated 以及 Scheduling/CustomActions/OnNodeStart、OnNodeConfigured 操作和参数。

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
  # Bucket permissions
  Iam:
    S3Access:
      - BucketName: bucket_name
        EnableWriteAccess: false
Scheduling:
  Scheduler: slurm
   [...]
  SlurmQueues:
    - Name: queue1
      [...]
      CustomActions:
        OnNodeStart:
          Script: s3://amzn-s3-demo-bucket/on-node-start.sh
          Args:
            - arg1
        OnNodeConfigured:
          Script: s3://amzn-s3-demo-bucket/on-node-configured.sh
          Args:
            - arg1
      Iam:
        S3Access:
          - BucketName: bucket_name
            EnableWriteAccess: false

使用Sequence设置（在 3.6.0 Amazon ParallelCluster 版本中添加）：

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
        [...]
    OnNodeUpdated:
      # Script URLs. The scripts are run in the same order as listed in the configuration, after the head node update is completed.
      Sequence:
        - Script: s3://amzn-s3-demo-bucket/on-node-updated1.sh
          Args:
            - arg1
        - Script: s3://amzn-s3-demo-bucket/on-node-updated2.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

该Sequence设置是从 3.6.0 Amazon ParallelCluster 版本开始添加的。指定 Sequence 后，您可以列出自定义操作的多个脚本。在配置自定义操作时， Amazon ParallelCluster 继续支持使用单个脚本而不包括 Sequence。

Amazon ParallelCluster 不支持同时包含单个脚本和Sequence同一个自定义操作。例如，如果您指定以下配置，则会 Amazon ParallelCluster 失败。
