**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
}
}
