Installation

TCA-gen2 is a microservice that will be configured and instantiated through Cloudify Manager.TCA-gen2 will be deployed by DCAE deployment among the bootstrapped services. This is more to facilitate automated deployment of ONAP regression test cases required services. During instantiation, the TCA-gen2 will fetch its configuration through the Config Binding Service. Steps to deploy using the CLI tool are shown below.

Deployment Prerequisite/dependencies

  • DCAE and DMaaP pods should be up and running.

  • MongoDB should be up and running

  • Make sure that cfy is installed and configured to work with the Cloudify deployment.

Deployment steps

Following are steps if manual deployment/undeployment is required. Steps to deploy are below

Enter the Cloudify Manager kuberenetes pod

Note

For doing this, follow the below steps

  • First get the bootstrap pod name by running run this: kubectl get pods -n onap | grep bootstrap

  • Then login to bootstrap pod by running this: kubectl exec -it <bootstrap pod> bash -n onap

  • Tca-gen2 blueprint directory (/blueprints/k8s-tcagen2.yaml). The blueprint is also maintained in gerrit and can be downloaded from https://git.onap.org/dcaegen2/platform/blueprints/tree/blueprints/k8s-tcagen2.yaml

  • Create input file required for deployment

    Configuration of the service consists of generating an inputs file (YAML) which will be used as part of the Cloudify install. The tca-gen2 blueprints was designed with known defaults for the majority of the fields.

    Below you will find examples of fields which can be configured, and some of the fields which must be configured. An input file is loaded into bootstrap container (/inputs/k8s-tcagen2-inputs.yaml).

  • Create deployment

    cfy install --blueprint-id tcagen2 --deployment-id tcagen2 -i /inputs/k8s-tcagen2-inputs.yaml /blueprints/k8s-tcagen2.yaml

To undeploy TCA-gen2, steps are shown below

  • Uninstall running TCA-gen2 and delete deployment
    cfy uninstall tcagen2
  • Delete blueprint
    cfy blueprints delete tcagen2
