Request Syntax

response = client.describe_launch_templates(
    DryRun=True|False,
    LaunchTemplateIds=[
        'string',
    ],
    LaunchTemplateNames=[
        'string',
    ],
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    NextToken='string',
    MaxResults=123
)

Parameters:

• DryRun (boolean) – Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

• LaunchTemplateIds (list) –

  One or more launch template IDs.

  • (string) –

• LaunchTemplateNames (list) –

  One or more launch template names.

  • (string) –

• Filters (list) –

  One or more filters.

  • create-time - The time the launch template was created.

  • launch-template-name - The name of the launch template.

  • tag:<key> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.

  • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

  • (dict) –

    A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.

    If you specify multiple filters, the filters are joined with an AND, and the request returns only results that match all of the specified filters.

    • Name (string) –

      The name of the filter. Filter names are case-sensitive.

    • Values (list) –

      The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR, and the request returns all results that match any of the specified values.

      • (string) –

• NextToken (string) – The token to request the next page of results.

• MaxResults (integer) – The maximum number of results to return in a single call. To retrieve the remaining results, make another call with the returned NextToken value. This value can be between 1 and 200.
