Disclaimer1 : This document is validated for OSE3.9 and will not work for other OSE version. Please contact the author incase you need support for other OSE versions

Disclaimer2: >

---

1> Clone the Openshift 3.9 Deployer from the Juniper git repo to a new directory (say foo)

2> Now copy contrail_master and contrail_nodes folder from the foo/openshift-ansible/roles directory to the roles directory of your openshift-ansible deployer

cp -r foo/openshift-ansible/roles/contrail_master openshift-ansible/roles/. cp -r foo/openshift-ansible/roles/contrail_node openshift-ansible/roles/.

3> Now add the following Patch to openshift_master playbook to ensure the contrail_master role gets executed

file openshift-ansible/playbooks/openshift-master/private/config.yml

Snippet of Code to be added >>>

• role: calico_master when: openshift_use_calico | default(false) | bool

• role: contrail_master when: openshift_use_contrail | default(false) | bool

4> Similarly add the contrail_nodes role to the openshift_nodes playbook

file openshift-ansible/playbooks/openshift-node/private/additional_config.yml

Snippet pf code to be added >>>>

>>> # Create group for kuryr nodes

• group_by: key: oo_nodes_use_{{ (openshift_use_kuryr | default(False)) | ternary('kuryr','nothing') }} changed_when: False

Create group for contrail nodes

• group_by: key: oo_nodes_use_{{ (openshift_use_contrail | default(False)) | ternary('contrail','nothing') }} changed_when: False

 name: kuryr
 tasks_from: node

when: openshift_use_kuryr | default(false) | bool

• name: Additional node config hosts: oo_nodes_use_contrail roles:
  • role: contrail_node contrail_master: "{{ groups.masters.0 }}" when: openshift_use_contrail | default(false) | bool

5> Now update the ose-intall (Openshift Inventory to include contrail Parameters for installation)

6> Update the ose-pre-requisite file (Add all the contrail pre-req to the ose-prerequisite file)
