  1. Navigate to the directory where the contrail-ansible-deployer-<xxxx>.<NN>.tgz was untarred.

    Example using OpenSDN 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.

  2. Update CONTRAIL_VERSION and CONTRAIL_CONTAINER_TAG to the desired version tag in this instances.yml file.

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

    CONTRAIL_VERSION = 2003.33
CONTRAIL_CONTAINER_TAG = 2003.33

  3. Run the following commands from contrail-ansible-deployer directory.

      ansible-playbook -e orchestrator=openstack -i inventory/ playbooks/install_openstack.yml -v
      ansible-playbook -e orchestrator=openstack -i inventory/ playbooks/install_contrail.yml -v

    • For OpenSDN with Kubernetes deployment:

      cd contrail-ansible-deployer
      ansible-playbook -e orchestrator=kubernetes -i inventory/ playbooks/install_k8s.yml -v
