To create a channel

The following create-channel example creates a channel with the specified configuration. A channel collects data from an MQTT topic and archives the raw, unprocessed messages before publishing the data to a pipeline.

aws iotanalytics create-channel \
    --cli-input-json file://create-channel.json

Contents of create-channel.json:

{
    "channelName": "mychannel",
    "retentionPeriod": {
        "unlimited": true
    },
    "tags": [
        {
            "key": "Environment",
            "value": "Production"
        }
    ]
}

Output:

{
    "channelArn": "arn:aws:iotanalytics:us-west-2:123456789012:channel/mychannel",
    "channelName": "mychannel",
    "retentionPeriod": {
        "unlimited": true
    }
}
