To update a pipeline

The following update-pipeline example modifies the settings of the specified pipeline. You must specify both a channel and a data store activity and, optionally, as many as 23 additional activities, in the pipelineActivities array.

aws iotanalytics update-pipeline \
    --cli-input-json file://update-pipeline.json

Contents of update-pipeline.json:

{
    "pipelineName": "mypipeline",
    "pipelineActivities": [
        {
            "channel": {
                "name": "myChannelActivity",
                "channelName": "mychannel",
                "next": "myMathActivity"
            }
        },
        {
            "datastore": {
                "name": "myDatastoreActivity",
                "datastoreName": "mydatastore"
            }
        },
        {
            "math": {
                "name": "myMathActivity",
                "math": "(((temp - 32) * 5.0) / 9.0) + 273.15",
                "attribute": "tempK",
                "next": "myDatastoreActivity"
            }
        }
    ]
