CONSTRUCTOR¶
IMPORTING¶
Optional arguments:¶
IV_HTTPTOKENS TYPE /AWS1/EC2LAUNCHTMPLHTTPTOKSS00 /AWS1/EC2LAUNCHTMPLHTTPTOKSS00¶
Indicates whether IMDSv2 is required.
optional- IMDSv2 is optional. You can choose whether to send a session token in your instance metadata retrieval requests. If you retrieve IAM role credentials without a session token, you receive the IMDSv1 role credentials. If you retrieve IAM role credentials using a valid session token, you receive the IMDSv2 role credentials.
required- IMDSv2 is required. You must send a session token in your instance metadata retrieval requests. With this option, retrieving the IAM role credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.Default: If the value of
ImdsSupportfor the Amazon Machine Image (AMI) for your instance isv2.0, the default isrequired.
IV_HTTPPUTRESPONSEHOPLIMIT TYPE /AWS1/EC2INTEGER /AWS1/EC2INTEGER¶
The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.
Default:
1Possible values: Integers from 1 to 64
IV_HTTPENDPOINT TYPE /AWS1/EC2LAUNCHTMPLINSTMETEN00 /AWS1/EC2LAUNCHTMPLINSTMETEN00¶
Enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is
enabled.If you specify a value of
disabled, you will not be able to access your instance metadata.
IV_HTTPPROTOCOLIPV6 TYPE /AWS1/EC2LAUNCHTMPLINSTMETPR00 /AWS1/EC2LAUNCHTMPLINSTMETPR00¶
Enables or disables the IPv6 endpoint for the instance metadata service.
Default:
disabled
IV_INSTANCEMETADATATAGS TYPE /AWS1/EC2LAUNCHTMPLINSTMETTG00 /AWS1/EC2LAUNCHTMPLINSTMETTG00¶
Set to
enabledto allow access to instance tags from the instance metadata. Set todisabledto turn off access to instance tags from the instance metadata. For more information, see Work with instance tags using the instance metadata.Default:
disabled
