Quickstart
==========

The ``dcae-cli`` is a Python command-line tool built to aide component
developers with the development and testing of their micro-service
component for the DCAE platform. It will help developers do functional
and integration testing of their components locally and on remote
environments as simple as possible.

The tool requires the component developers to create a valid component
specification for their component which is used by the tool. This same
component specification will be published in the :any:`onboarding catalog <glossary-onboarding-catalog>` at the end of development
and testing.

.. The git repository can be found `here <ONAP%20LINK%20TBD>`__

Pre-requisite
-------------

For Docker
~~~~~~~~~~

There are two options for development with Docker: developing locally on
your machine which requires Docker to be installed and developing
remotely by deploying onto remote infrastructure.

For local development
^^^^^^^^^^^^^^^^^^^^^

-  You must install `Docker
   engine <https://docs.docker.com/engine/installation/>`__ locally on
   your machine.
-  You must know the *external ip* of where the Docker engine is
   running. The external ip is needed so that service discovery will
   wire up correctly.

   -  For OSX users, this means making sure the VirtualBox VM that is
      running your Docker engine has a bridged adapter and getting the
      ip of that adapter.

For remote development
^^^^^^^^^^^^^^^^^^^^^^

You need access to a remote host with Docker engine installed with
remote API access. You must have the associated connection information:
domain name or IP and port (should be either 2375 or 2376). This
information should be set in :any:`an active profile <setting-profile>`.

For CDAP
~~~~~~~~

TBD

Install
-------

::

    pip install --extra-index-url https://YOUR_NEXUS_PYPI_SERVER/simple dcae-cli

To do an upgrade, use the ``--upgrade`` flag.

Configuration
~~~~~~~~~~~~~

When you run the tool for the first time, the tool will create a
`configuration
directory <http://click.pocoo.org/5/api/#click.get_app_dir>`__ and
generate a configuration file.

Configuration is first sourced from an remote server that the platform
team manages. This is overlaid with configuration details that you will
be prompted to input particularly your user id.

``--reinit``
^^^^^^^^^^^^

Configuration can be re-initialized or reset. There is a ``--reinit``
flag that is to be used to re-initialize your configuration and your
environment profiles.

To re-initialize:

::

    $ dcae_cli --reinit

Verify
~~~~~~

Verify that its installed:

::

    $ dcae_cli --help
    Usage: dcae_cli [OPTIONS] COMMAND [ARGS]...

    Options:
      -v, --verbose  Prints INFO-level logs to screen.
      --reinit       Re-initialize dcae-cli configuration
      --version      Show the version and exit.
      --help         Show this message and exit.

    Commands:
      catalog
      component
      data_format
      profiles

Version
-------

You can verify the version of the dcae-cli with the following command:

::

    $ dcae_cli --version
