 * `subnet_id` - (Optional) VPC Subnet ID to launch in.
 * `tags` - (Optional) A map of tags to assign to the resource. Note that these tags apply to the instance and not block storage devices. If configured with a provider [`default_tags` configuration block](/docs/providers/aws/index.html#default_tags-configuration-block) present, tags with matching keys will overwrite those defined at the provider-level.
 * `tenancy` - (Optional) Tenancy of the instance (if the instance is running in a VPC). An instance with a tenancy of dedicated runs on single-tenant hardware. The host tenancy is not supported for the import-instance command.
-* `user_data` - (Optional) User data to provide when launching the instance. Do not pass gzip-compressed data via this argument; see `user_data_base64` instead.
-* `user_data_base64` - (Optional) Can be used instead of `user_data` to pass base64-encoded binary data directly. Use this instead of `user_data` whenever the value is not a valid UTF-8 string. For example, gzip-encoded user data must be base64-encoded and passed via this argument to avoid corruption.

 ~> **NOTE:** Do not use `volume_tags` if you plan to manage block device tags outside the `aws_instance` configuration, such as using `tags` in an [`aws_ebs_volume`](/docs/providers/aws/r/ebs_volume.html) resource attached via [`aws_volume_attachment`](/docs/providers/aws/r/volume_attachment.html). Doing so will result in resource cycling and inconsistent behavior.
