Config keys are the `config_key` values specified in your component specification streams section where the streams must be type message router or data router. Information about the associated connection details can be found on [this page](dmaap-connection-objects.md). Please check it out. +**NOTE** You must undeploy this component when finished testing. This is important to conserve resources in the environment. -For example, if you have a component specification that has the following streams entry: +#### Run a component that subscribes to Dmaap Message Router or Data Router -```json -"streams": { - "publishes": [{ - "format": "ves", - "version": "1.0.0", - "type": "message router", - "config_key": "ves_connection" - }] -} ``` - -Then to deploy and to run your component, you must use the `--dmaap-file` command and pass in a JSON that looks like: - -```json -{ - "ves_connection": { - "type": "message_router", - "dmaap_info": { - "topic_url": "https://we-are-message-router.us:3905/events/some-topic" - } - } -} +$ dcae_cli -v component run $component-that-uses-dmamp --dmaap-file $dmaap-connection-object ``` -The provided DMaaP JSON is used to simulate the output of provisioning and will be used to merge with the generated application configuration at runtime. - -Your final application config will look like: +#### Run a component that expects input that is `sourced at deployment` -```json -{ - "streams_publishes": { - "ves_connection": { - "type": "message_router", - "dmaap_info": { - "topic_url": "https://we-are-message-router.us:3905/events/some-topic" - } - } - } -} ``` - -#### Data router subscribers - -Note for data router subscriber testing, you will need the delivery url in order to provision the subscriber to the feed. This is constructed at deployment time and will be provided by the dcae-cli after you deploy your component. The delivery urls will be displayed to the screen: - +$ dcae_cli -v component run $component-that-expects-dti --inputs-file $input-file-to-simulate-dti ``` -DCAE.Run | WARNING | Your component is a data router subscriber.

Add a `dti` entry to represent one or more instances of `vnfType-vnfFuncId` for your component. -Components may have configuration parameters whose values are to be sourced at deployment time. For example, there are components whose configuration parameters are to come from DTI events which are only available when the component is getting deployed. These configuration parameters must be setup correctly in the [component specification](http://localhost:8000/components/component-specification/docker-specification/#configuration-parameters) by setting the property `sourced_at_deployment` to `true` for each and every parameter that is expected to come in at deployment time. +For example, in 1802, go (here)[http://zldcrdm5bdcc2cnsl00.2f3fb3.rdm5b.tci.att.com:8500/ui/#/zldcrdm5bdcc2/kv/). -Once your component specification has been updated correctly, you must use the `--inputs-file` command-line argument when running the commands `dev` or `run` with your component.

The DCAE platform is responsible for running and managing DCAE service components reliably. Currently, the DCAE platform supports two types of components, CDAP applications and Docker containers. For each, there are requirements that must be met for the component to integrate into the DCAE platform (see [CDAP](component-type-cdap.md) and [Docker](component-type-docker.md)). -### Components requires one or more data formats. +### A Component requires one or more data formats. -Components are software applications that do some function.
