    Example using Tungsten Fabric Release 2003:

    cd contrail-ansible-deployer-2003.33/contrail-ansible-deployer/config/

    vi contrail-ansible-deployer-2003.33/contrail-ansible-deployer/config/instances.yaml

    Sample instances.yaml files for various other deployments are available at the same directory.

    Access CONTRAIL_CONTAINER_TAG located at README Access to Tungsten Fabric Registry 20xx  . For example:

    CONTRAIL_VERSION = 2003.33

      ansible-playbook -e orchestrator=openstack -i inventory/ playbooks/install_contrail.yml -v
    • For TF with Kubernetes deployment:

      cd contrail-ansible-deployer
