In order to do testing with message router topics or with data router feeds, the developer must provision the topic or the feed manually and provide the connection details in the form of a JSON in a file to the dcae-cli. This file is to be passed in when using the `run` and `dev` commands with the option `--dmaap-file`. + +The structure of the DMaaP JSON is an object of config keys to matching topic or feed connection details. 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. + +For example, if you have a component specification that has the following streams entry: + +```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" + } + } +} +``` + +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: + +```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.Run | WARNING | Your component is a data router subscriber. Here are the delivery urls: + + some-sub-dr: http://SOME_IP:32838/identity + +``` + +## Publishing component + +Once components have their component specifications crafted and validated and have been tested, components should be published in the shared onboarding catalog using the `publish` sub-command for both data formats and components. You must publish all data formats of a component before publishing a component. + +Publishing will change the status of a component, be made accessible for other developers to use, and will generate the associated TOSCA models for use in designing of compositions. + +``` +dcae_cli component publish sandbox.platform.laika:0.5.0 +``` + +## Shared catalog + +`catalog` is the sub-command used to access and to browse the shared onboarding catalog to view components and data formats that have been published and that are being worked on. Components and data formats have two statuses `staged` and `published`. + +Staged means that the resource has been simply added and is under development. It is to be used only by the owner. Published means that the resource has been fully developed and tested and is ready to be shared. + +Published components can be deployed by non-owners and published data formats can be used in component specifications of non-owners. + +There are two available operations: + +``` +$ dcae_cli catalog --help +Usage: dcae_cli catalog [OPTIONS] COMMAND [ARGS]... + +Options: + --help Show this message and exit. + +Commands: + list + show +``` + +Staged components can be viewed under the `list` operation using the `--expanded` flag. |
