Cloud specific ansible role
We will need to create a CSP specific ansible role which can perform tasks such as upload / download / delete of files and folders etc.
Take a look at one of the existing cloud provider role such as AWS / GCP to understand what all operations are required as part of the role.
Cloud specific Elasticsearch plugin
We will need to create a CSP specific ansible role which can perform elasticsearch snapshot
Take a look at one of the existing cloud provider role such as AWS / GCP to understand the snapshot approach
Under the hood, we are using the cloud provider plugin for elasticsearch snapshot - https://www.elastic.co/guide/en/elasticsearch/plugins/6.8/repository.html
The plugin gets installed and configured using the ansible role
Ansible tasks related to storage buckets
Below is a sample block which uploads to AWS S3 bucket (https://github.com/project-sunbird/sunbird-devops/blob/release-5.1.0/ansible/artifacts-upload.yml#L30-L41 )
- name: upload artifact to aws s3
include_role:
name: aws-cloud-storage
tasks_from: upload.yml
vars:
local_file_or_folder_path: "{{ artifact_path }}"
s3_bucket_name: "{{ cloud_storage_artifacts_bucketname }}"
s3_path: "{{ artifact }}"
aws_default_region: "{{ cloud_public_storage_region }}"
aws_access_key_id: "{{ cloud_artifact_storage_accountname }}"
aws_secret_access_key: "{{ cloud_artifact_storage_secret }}"
when: cloud_service_provider == "aws"
In order to support a new CSP, we will need to add a similar block which can invoke the CSP specific roles and upload to CSP storage buckets
Below is the list of files that need to be modified to include the CSP storage ansible role
ansible/bootstrap.yml ansible/dial_upload-schema.yml ansible/uploadFAQs.yml ansible/deploy-plugins.yml ansible/desktop-faq-upload.yml ansible/artifacts-upload.yml ansible/es.yml ansible/kp_upload-schema.yml ansible/roles/prometheus-backup-v2/tasks/main.yml ansible/roles/postgresql-backup/tasks/main.yml ansible/roles/prometheus-restore/tasks/main.yml ansible/roles/cert-templates/tasks/main.yml ansible/roles/prometheus-backup/tasks/main.yml ansible/roles/cassandra-backup/tasks/main.yml ansible/roles/postgres-managed-service-restore/tasks/main.yml ansible/roles/desktop-deploy/tasks/main.yml ansible/roles/cassandra-restore/tasks/main.yml ansible/roles/jenkins-backup-upload/tasks/main.yml ansible/roles/mongodb-backup/tasks/main.yml ansible/roles/redis-backup/tasks/main.yml ansible/roles/postgresql-restore/tasks/main.yml ansible/roles/es6/tasks/main.yml ansible/roles/log-es6/tasks/main.yml ansible/roles/postgres-managed-service-backup/tasks/main.yml ansible/roles/grafana-backup/tasks/main.yml ansible/assets-upload.yml ansible/artifacts-download.yml ansible/plugins.yml
Ansible Variables Private Repo Templates
All the cloud specific variables (for example, bucket name, access key, secret key etc.) are provided to adopters using ansible variable template files
The ansible variable template files need to be updated to include CSP specific variables so that a user is aware on what variables need to be filled based on the cloud provider
The templates are located here - https://github.com/project-sunbird/sunbird-devops/tree/release-5.1.0/private_repo/ansible/inventory/dev
An adopter updates all the files mentioned in the above url which also includes the cloud specific variables

The implementation is same as the previous section (no private repo template in this repo, its part of the previous section)
Below is the list of files that require the changes
