The dcae-cli is a Python command-line tool used to manage and to test components and their data formats in onboarding.
Please review the [DCAE platform documentation](ONAP URL TBD) which has a detailed [dcae-cli walkthrough](ONAP URL TBD).
The dcae-cli requires access to an onboarding catalog which is a postgres database. If there is no shared instance for your team or organization, then a workaround is to run a local instance of postgres on your machine. One quick way is to run a postgres Docker container:
docker run -e POSTGRES_PASSWORD=<your password> -e PGDATA=/var/lib/postgresql/data/pgdata -v <local directory>:/var/lib/postgresql/data/pgdata -p 5432:5432 -d postgres:9.5.2
Use your favorite sql client to log into this local instance and create a database named dcae_onboarding_db.
Now that your onboarding catalog is setup, run dcae_cli --reinit and walkthrough the prompts to configure your dcae-cli to point to this local instance.
