Configure PNDA creation process


The PNDA creation process is controlled primarily via a YAML configuration file.

A template YAML configuration can be found in the pnda-cli repository.

Configure pnda_env.yaml

Designate client machine

Create or designate a suitable machine for running the PNDA CLI. We recommend CentOS 7.

Obtain code

Clone the pnda-cli repository repository from the master branch at a specific release tag (e.g. release/4.0) to the client machine.

Copy pnda_env_example.yaml to create pnda_env.yaml

Set access credentials

Set the following fields under openstack_parameters section in pnda_env.yaml . The values can be obtained by referring to the Keystone authentication details obtained in the preparation phase.

Field Value
KEYSTONE_USER User for creating PNDA
KEYSTONE_PASSWORD Password for user
KEYSTONE_TENANT Tenant for creating PNDA

Object storage

Set pnda_application_repo.PNDA_APPS_CONTAINER to the Application container configured during the preparation phase.

Set pnda_application_repo.PNDA_APPS_FOLDER to the Application folder configured during the preparation phase.

Set pnda_data_archive.PNDA_ARCHIVE_CONTAINER to the Dataset archive container configured during the preparation phase.

Hadoop distribution

Decide whether you want to run the Cloudera CDH or the Hortonworks HDP Hadoop distribution.

Set hadoop.HADOOP_DISTRO to either CDH or HDP.

Set source of SaltStack provisioning scripts

The PNDA software is installed and configured using the SaltStack code found in the platform-salt repository. There are two main options to provide source for platform-salt:

  1. Set platform_salt.PLATFORM_GIT_REPO_URI to the remote git URI and platform_salt.PLATFORM_GIT_BRANCH at the specified branch to be cloned during provisioning. If authenticated access to platform_salt.PLATFORM_GIT_REPO_URI is required, then place the ssh key to use, named git.pem, in the top level directory of "pnda-cli" repository and also set platform_salt.PLATFORM_GIT_REPO_HOST to the hostname of the server.

  2. A local copy of platform-salt can be used by setting (platform_salt.PLATFORM_SALT_LOCAL) to the path to the platform-salt folder on the local machine running

PNDA mirror

Set mirrors.PNDA_MIRROR to the URI determined by the placement of the mirror and build components in the staging phase.

Other fields

There are a wide range of parameters that can be set, please refer to pnda_env_example.yaml in the pnda-cli repository for more details.

Security Material

Perimeter security (FQDN's and associated certificates/private keys)

Access to the PNDA cluster requires user authentication over a secure connection. In order to secure this user authentication, the perimeter servers require certification material which allows validating the FQDN used to access those servers to further authenticate and secure the connection to those servers.

For PRODUCTION ENVIRONMENTS, this security material MUST be generated outside the PNDA realm and dropped under the platform-certificates directory tree. Consult the README files under that same directory and sub-directories for further details on the required material.

For NON-PRODUCTION ENVIRONMENTS, a helper tool (tools/ is provided that can auto-generate the required server certificates based on an existing CA (private key) or based on a newly generated CA (when no private key is detected in the ./platform-certificates directory by the helper tool).
