dcae_cli Commands

The dcae_cli tool has four command groups. Each has several sub-commands.

catalog

The catalog command lists and shows resources (components and data_formats) in the ‘onboarding’ catalog (regardless of the owner). A resource can have a status of staged or published. By default, only published resources are displayed. To see staged resources, add the –expanded argument.

Catalog Status Meaning
staged resource has be added (and validated), but is under development
staged data_formats can only be referenced in their owners component specs
staged components can only be deployed by their owners
published resource has been tested and can be shared
  published data_formats can be used in anyone’s component spec
  published components and be deployed by anyone

component

The component command is for validating (adding), listing, showing, verifying generated configuration, running, undeploying, and publishing components that YOU own.

$ dcae_cli component --help
Usage: dcae_cli component [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  add
  dev       Set up component in development for...
  list      Lists components in the onboarding catalog.
  publish   Pushes COMPONENT to the onboarding catalog
  run       Runs the latest version of COMPONENT.
  show      Provides more information about COMPONENT
  undeploy  Undeploys the latest version of COMPONENT.

Add a Component

A component must be added to the onboarding catalog in order to be tested by the dcae_cli tool. The process of adding a component also validates it’s component specification. In order to add a component, the component docker image (or CDAP jar) must exist locally.

Components in the onboarding catalog can be run by others, once they are published. Published components cannot be modified or deleted. Rather a new version can be created instead.

Validated component specs are used later to generate Tosca models and Cloudify Blueprints for the component, which makes them available for use in the SDC Tool for creating services.

$ dcae_cli component add --help
Usage: dcae_cli component add [OPTIONS] COMPONENT-SPECIFICATION

Options:
  --update  Updates a previously added component if it has not been already
            published

The fields Name, Version, Type, Description are referenced from the component specification’s self JSON. Use the “–deployed” argument to see more details on deployed components


Run a Component

The run operation is to be used for running your application in its container remotely on the activated environment. Docker containers have the additional option to run locally on your development machine. If the component uses Dmaap, you can specify the Dmaap Connection Object as well. Refer to Dmaap Connection Object.

When you run a component via the dcae_cli Tool, remember the blueprint has not been created and is not used for deployment.

In order to run the component, the data formats and component must have been added to the onboarding catalog.

DOCKER NOTE: Make sure the Docker image has been uploaded to the shared registry.

A docker component can be run in either attached or unattached mode. (Default is unattached).

Mode Description
attached component is run in the ‘foreground’, container logs are streamed to stdout. Ctrl-C is used to terminate the dcae_cli session.
unattached component is run in the ‘background’, container logs are viewed via docker logs command, container runs until undeployed with dcae_cli undeploy command.

Run a component in attached mode:

$ dcae_cli -v component run --attached sandbox.platform.yourapp:0.5.0

NOTE You must undeploy this component when finished testing. This is important to conserve resources in the environment.

Run a component that subscribes to Dmaap MR or DR

$ dcae_cli -v component run --attached --dmaap-file $dmaap-connection-file sandbox.platform.yourapp:0.5.0

Undeploy a Component

The undeploy command is used to undeploy any instance of a specified component/version that you have deployed. This includes cleaning up the configuration.

$ dcae_cli component undeploy sandbox.platform.yourapp:0.5.0
DCAE.Undeploy | WARNING | Undeploying components: 1
DCAE.Undeploy | WARNING | Undeployed components: 1

Publish a component

Once a component has been tested, it should be published in the onboarding catalog using the publish sub-command .
Publishing will change the status of the component (from staged to published), indicating that it has been tested, and making it accessible for other developers to use.

Note Before a component can be published, all data_formats that it references must be published.

dcae_cli component publish sandbox.platform.yourapp:0.5.0

Show a Component

This will print out the contents of a component and is useful to copy a component spec.

$ dcae_cli component show

Run the dev command

The dev command is used as part of a process to see the platform generated configuration. It established the environment variables and is best explained here.

$ dcae_cli component dev component-spec.json
Ready for component development

data_format

The data_format command is for validating (adding), listing, showing, publishing data_formats that YOU own. data_formats can also be generated with this command.

$ dcae_cli data_format --help
Usage: dcae_cli data_format [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  add       Tracks a data format file DATA_FORMAT-SPECIFICATION...
  generate  Create schema from a file or directory...
  list      Lists all your data formats
  publish   Publishes data format to make available to others...
  show      Provides more information about FORMAT

Add a Data Format

A data_format must be in the onboarding catalog in order to be referenced in the component specification. The process of adding a data_format also validates it. Data_formats in the onboarding catalog can be run by others, once they are published. Published data_formats cannot be modified or deleted. Rather a new version can be created instead.

$ dcae_cli data_format add --help
Usage: dcae_cli data_format add [OPTIONS] DATA_FORMAT-SPECIFICATION

Options:
  --update  Updates a previously added data_format if it has not been already
            published

The fields name, version, description are referenced from the data format specification’s self JSON. Status represents the status of the data format in the catalog. See Publish a Data Format for more info.


Show a Data Format

This will print out the contents of a data_format and is useful for copying a data_format.

$ dcae_cli data_format show

Publish a Data Format

Once a data_format has been tested (by referencing it in a component spec that has been tested), it should be published in the onboarding catalog using the publish sub-command .
Publishing will change the status of the data_format (from staged to published), indicating that it has been tested, and making it accessible for other developers to use.
$ dcae_cli data_format publish data_format.json

Generate a Data Format

If you already have a valid input or output file, you can use the generate command to create the it’s data format specification.

$ dcae_cli data_format generate name:version file-or-dir-path

profiles

Theprofiles command is for creating, deleting, listing, showing, activating, and updating (set) profiles. The profile contains environment variables used to connect to different environments. This is used in the running and deployment of a component using the dcae_cli component run or dev command.

$ dcae_cli profiles --help
Usage: dcae_cli profiles [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  activate  Sets profile NAME as the active profile
  create    Creates a new profile NAME initialized with...
  delete    Deletes profile NAME
  list      Lists available profiles
  set       Updates profile NAME such that KEY=VALUE
  show      Prints the profile dictionary

List the available profiles

$ dcae_cli profiles list
*  solutioning
   1710
   1802

The * identifies the active profile. dcae-cli is currently installed with profiles for the solutioning, 1710, and 1802 environments. They are intended for the following:

Environment Description
solutioning default environment; used for initial component developer testing with the dcae_cli tool.
1710 FTL3 (Functional Testing Lab 3) environment, which represents the 1710 release.
1802 FTL3a (Functional Testing Lab 3a) environment, which represents the 1802 release.

Show the details of a profile

$ dcae_cli profiles show solutioning
{
    "cdap_broker": "cdap_broker",
    "config_binding_service": "config_binding_service",
    "consul_host": "yourconsulhost.com",
    "docker_host": "yourdockerhost.com:2376"
}

Activate a profile

To switch among profiles, use the activate sub-command. A subsequent list will reveal the change made.

$ dcae_cli profiles activate test

Create a new profile

If you want to work in a different environment using the dcae_cli tool, you can make your own profile. (The environment must be a working DCAE Platform environment).

$ dcae_cli profiles create new-profile

After creating you would assign the variables with the set sub-command. Then activate it to use.


Set variables in a profile

$ dcae_cli profiles set $profile $key $value

Delete a profile

$ dcae_cli profiles delete new-profile
