Terraform read single-item list-CodePudding

In terraform's documentation it states:

A single item list of HLS ingest information

And then, a nested value of:

A list of the ingest endpoints

How can I get the first item entry of the list of endpoints?

CodePudding user response：

Since the resource was not provided, we will assume the example in the documentation:

resource "aws_media_package_channel" "kittens" {
  channel_id  = "kitten-channel"
  description = "A channel dedicated to amusing videos of kittens."
}

Given that resource, we can access the exported resource attribute with the normal namespace of aws_media_package_channel.kittens.hls_ingest. Since this is a single item list containing a map, we would then access aws_media_package_channel.kittens.hls_ingest[0].ingest_endpoints. You stated that you want the first element of this nested list, and therefore with the customary syntax for the zeroth element:

aws_media_package_channel.kittens.hls_ingest[0].ingest_endpoints[0]

where you can then access values of that map by referencing the key e.g. url as per normal.
