This set of playbooks installs Contrail Networking using a microservices architecture.
This set of commands will configure the instance and install AIO contrail with k8s on the instance:
ssh-copy-id 192.168.1.100
yum install -y ansible
git clone http://github.com/Juniper/contrail-ansible-deployer
cd contrail-ansible-deployer
ansible-playbook -i inventory/ -e orchestrator -e '{"instances":{"bms1":{"ip":"192.168.1.100","provider":"bms"}}}' playbooks/configure_instances.yml
ansible-playbook -i inventory/ -e orchestrator=none -e '{"instances":{"bms1":{"ip":"192.168.1.100","provider":"bms"}}}' playbooks/install_contrail.yml
The ip address 192.168.1.100 has to be replaced with the instances ip address
All processes are running in their own container. The containers are grouped together into services, similiar to PODs in kubernetes.

- CentOS 7.4 (kernel >= 3.10.0-693.17.1)
- working name resolution through either DNS or host file for long and short hostnames of the cluster nodes
- docker engine (tested with 17.03.1-ce)
- docker-compose (tested with 1.17.0) installed
- docker-compose python library (tested with 1.9.0)
- in case of k8s will be used, the tested version is 1.9.2.0
- for HA, the time must be in sync between the cluster nodes

The playbooks support installing Contrail on these providers: -- bms - Baremetal Server -- kvm - KVM hosted Virtual Machines -- gce - GCE hosted Virtual Machines -- aws - AWS hosted Virtual Machines
The playbook contains three plays:
- playbooks/provision_instances.yml
Provisions operating system instances for hosting the containers to the following infrastructure providers:
-- kvm -- gce -- aws -- azure (to be implemented) -- openstack (to be implemented)
- playbooks/configure_instances.yml
Configures provisioned instances. Applicable to all providers. Installs software, configures operating system as outlined under prerquisites.
- playbooks/install_contrail.yml
Pulls, configures and starts Contrail containers.
Configuration for all three plays is done in a single file (default locataion: config/instances.yaml) The configuration has multiple main sections.
This section configures provider specific settings.

In case kolla openstack is deployed, this section defines the paramters for it.
kolla_configuration:
Instances are the operating systems on which the containers will be launched. The instance configuration has only a very few provider specific knobs. The instance configuration specifies which roles are installed on which instance. Furthermore instance wide and role specifc contrail and kolla configurations can be specified, overwriting the paramters from the global contrail and kolla configuration settings.
This is a very simple all in one GCE instance. It will install all contrail roles and kubernetes master and node using default configuration.
instances:
gce1: # Mandatory. Instance name
provider: gce # Mandatory. Instance runs on GCE
This example uses three EC2 instances to deploy and AIO HA setup with all roles and default parameters.
instances:
aws1:
provider: aws
aws2:
provider: aws
aws3:
provider: aws
A KVM based instance only installing contrail control plane containers.

k8s_master:
GCE k8s HA with separate control and data plane instaces AWS Kolla HA with separate control and data plane instaces KVM Kolla per instance and role configuration KVM Kolla and k8s BMS remote compute configuration
Instance provisioning:
ansible-playbook -i inventory/ playbooks/provision_instances.yml
Instance configuration:
ansible-playbook -i inventory/ playbooks/configure_instances.yml
Contrail installation: orchestrator can be openstack (installs kolla) or none (for pure k8s installations).
ansible-playbook -e orchestrator=none|openstack -i inventory/ playbooks/install_contrail.yml
The location of the configuration file (config/instances.yaml) can be changes using the -e config_file= parameter, i.e.:
ansible-playbook -i inventory/ -e config_file=/config/instances_gce.yml playbooks/install_contrail.yml
yaml and json formats are supported.
