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-2.4.2.0
#For Contrail R5.0 use
git clone -b R5.0 http://github.com/Juniper/contrail-ansible-deployer
#For master branch use
git clone http://github.com/Juniper/contrail-ansible-deployer
cd contrail-ansible-deployer
ansible-playbook -i inventory/ -e orchestrator=kubernetes -e '{"instances":{"bms1":{"ip":"192.168.1.100","provider":"bms"}}}' playbooks/configure_instances.yml
ansible-playbook -i inventory/ -e orchestrator=kubernetes -e '{"instances":{"bms1":{"ip":"192.168.1.100","provider":"bms"}}}' playbooks/install_contrail.yml
ansible-playbook -i inventory/ -e orchestrator=kubernetes -e '{"instances":{"bms1":{"ip":"192.168.1.100","provider":"bms"}}}' playbooks/install_k8s.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.

Please check [Optional Contrail Analytics Components](https://github.com/Juniper/contrail-ansible-deployer/blob/master/README.md#optional-contrail-analytics-component
- CentOS 7.4 (kernel >= 3.10.0-693.17.1)
- Ansible (==2.4.2.0)
- 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
** NOTE ** Ansible 2.4.2.0 is temporary fix for 2.5 issues with our playbooks.

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.

Complete list of contrail_configuration
In case kolla openstack is deployed, this section defines the paramters for it.
kolla_config:
customize:
nova.conf: |
[libvirt]
virt_type=qemu
cpu_mode=none
kolla_globals:
network_interface: "eth0"
kolla_external_vip_interface: "eth0"
enable_haproxy: "no"
enable_ironic: "no"
enable_swift: "no"
kolla_passwords:
metadata_secret: strongmetdatasecret
keystone_admin_password: password
More documentation about kolla-ansible parameters can be found in kolla-ansible repository.
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.
instances:
kvm1:
provider: kvm
ip: 10.0.0.1
host: 1.1.1.1
bridge: br1
roles:
config_database:

analytics_database:

webui:
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 -e orchestrator=none|openstack|kubernetes -i inventory/ playbooks/configure_instances.yml
OpenStack installation:
ansible-playbook -i inventory/ playbooks/install_openstack.yml
Contrail installation: orchestrator can be openstack or none or kubernetes (for pure k8s installations).
ansible-playbook -e orchestrator=none|openstack|kubernetes -i inventory/ playbooks/install_contrail.yml
Contrail's k8s installation: orchestrator can be openstack or kubernetes (for pure k8s installations). openstack can be used here for hybrid clouds like Contrail+OpenStack+K8s
ansible-playbook -e orchestrator=openstack|kubernetes -i inventory/ playbooks/install_contrail.yml
The location of the configuration file (config/instances.yaml) can be changed 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.
This repository contains several playbooks which are to be involved separately and various roles which are named acccording to the following:
- XXX_deployer roles (contrail_deployer, aws_deployer, kolla_deployer, ...) are the roles which are to be run on the deployment machine (the one running ansible_deployer) and to affect the whole cluster. They prepare global variables, initialize kolla or k8s cluster, etc. They are named after ansible_deployer and could've been named contrail_ansible_deployer, aws_ansible_deployer, etc.
- XXX roles (contrail, k8s, vcenter, ...) are the roles to be assigned to particular nodes - computes, controllers, analytics_databases and such.
