Easy installer (Draft)

Overview:

Easy installer is meant to install Sunbird Ed platform on Kubernetes cluster which helps the adopter to setup Sunbird Ed platform within in few hours.

Pre-requisites:

Server or Laptop with Ubuntu 20.04 LTS operating system
Azure Kubernets Cluster
Azure Storage Account
Domain name and SSL Certificates
Google re-captcha
Google OAuth Credentials

To successfully complete Sunbird installation, you need to have:

System administrator permissions to the cloud resources
Hands-on experience in administering and debugging Linux systems
Hands-on experience using Docker and Kubernetes to run containerized workloads

Steps:

Provision Pre-requisites: Current easy installer supports azure cloud service provider. Please provision the following resources required
- Azure Kubernetes Cluster: Please follow the steps mentioned in the below azure documentation link to provision AKS cluster using azure protal and generate the kubeconfig file for the same and save it in the server/local machine from where you will be running the installer script.
  https://learn.microsoft.com/en-us/azure/aks/learn/quick-kubernetes-deploy-portal?tabs=azure-cli
  - kubernetes version: 1.24.x
  - Node size: 4 Core, 16 GB RAM,
  - Node count range: 6 to 10
- Install az cli https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-linux?pivots=apt
- Azure Storage account with following containers
  - sunbird-contents-dev public container
  - flink-state-backend private container
- Google re-captcha : Follow the steps mentioned in the below link. Select Challenge(v2) -> Invisible reCAPTCHA badge. https://www.google.com/recaptcha/admin/create
- Google OAuth Credentials: Follow the steps mentioned in the below link and set Authorised redirect URIs value to https://{domain-name}/oauth2/callback . Save Client id and Client secret values. https://developers.google.com/workspace/guides/create-credentials#oauth-client-id
- Domain name and SSL Certificates: You can create free Letsencrypt SSL certificates using https://punchsalad.com/ssl-certificate-generator/ for the domain which is valid for 90 days. Or purchase the SSL certs from Godaddy or Namecheap like vendors
Update environment values
- Clone the repository
  git clone https://github.com/project-sunbird/sunbird-devops -b oneclickinstaller cd sunbird-devops/oneclickinstaller chmod +x *sh
- Use your favourite text editor and update variables mentioned in global-values.yaml. Follow the instructions mentioned in the global-values.yaml file under every variable
Run the Ed easy installer bash script. While the installer is running, you can view the deployments to the kubernetes cluster using any kubernetes client like kubectl or k9s. This step take 45 min to 1 hour based on the internet speed on the machine where you are running the script. Take a break and check back !

K9s download link: https://k9scli.io/topics/install/

bash ./install-ed.sh /path/to/kubeconfig.yaml -i ed-install

Manual keycloak configurations

NOTE: These manual configurations will be automated in the next consequent releases

Port forward to keycloak pod to access admin console through web browser. If you are running installer from server(not local machine).Make sure SSH tunnel is done b/w local machine to server.Make sure there is no process running on port 8080 on the system from where you are running the installer. Also, make sure context to kubectl is set to the right kubernetes cluster.
```
POD_NAME=$(kubectl get pods -n dev | grep keycloak | awk '{print $1}')
```
```
kubectl port-forward -n dev "$POD_NAME" 8080:8080 
```
Go to http://localhost:8080/auth/admin/master/console/#/realms/sunbird/clients
username: admin password: admin
- Click lms client -> Select service account roles -> Click on Client roles drop down -> Select realm management -> Select manage-users in Available Roles -> Click on Add Selected
- Click on Credentials TAB-> Copy the secret value -> Update sunbird_sso_client_secret variable value in global-values.yaml with the copied secret value
- Click on Realm Settings-> Keys -> Click on public key button-> Copy the key. Update the variables sunbird_sso_publickey and keycloak_sunbird_realm_public_key in global-values.yaml with the copied public key
- Click on Realm Settings -> Click on Themes -> Select sunbird as a login theme -> click save
Goto http://localhost:8080/auth/admin/master/console/#/realms/sunbird/user-federation Click on cassandra-storage-provider -> Copy the Provider ID. Update the sunbird_keycloak_user_federation_provider_id variable in global-values.yaml with the copied Provider ID
Goto http://localhost:8080/auth/admin/master/console/#/realms/sunbird/keys -> copy KID of Type RSA . Update the variable keycloak_sunbird_realm_kid in global-values.yaml

Run the Ed easy installer post install script

bash ./install-ed.sh /path/to/kubeconfig.yaml -i postscript

Update the DNS record: Get the public ip printed on the console and add DNS A record for the same domain you have added to global-values.yaml. Access the Ed instance using https://{domain-name}

Functional Configuration:

Once above steps are completed, functional configurations need to be setup. Following postman collection helps to setup minimal functional configuration.You can leverage same postman collection to setup functional configuration for your use case.

To configure these functionalities, you will need to use the Postman tool. You can download and install the Postman tool by visiting the following link: https://www.postman.com/downloads/.

Please refer the below mentioned postman collection to setup minimal functional configuration for content creation workflow.

Download the postman collection of Sunbird-Ed functional configuration

https://github.com/project-sunbird/sunbird-devops/blob/oneclickinstaller/oneclickinstaller/collection.json

Download the postman environment variable file

https://github.com/project-sunbird/sunbird-devops/blob/oneclickinstaller/oneclickinstaller/environment.json

Import postman collection and environment variables to postman tool

https://learning.postman.com/docs/getting-started/importing-and-exporting-data/#importing-postman-data\

Update below mentioned environmental variables in postman tool. Please refer global_values.yaml file for varaible values.

Environment key name

global_values.yaml key name

Description

host

domain

http://example.co.in/

kong_api_key

Bearer {{core_vault_sunbird_api_auth_token}}

Bearer xxx.yyy.zzz

Import the Postman collection and environment files. Then, go to the "Environment" section and choose the "sunbird-easeinstall" environment. Update the values of the "host" and "kong_api_key" variables, and remember to save the changes.
Once you have updated the environment variables, click on the "Collections" tab located in the upper-left corner. From the dropdown menu in the upper-right corner, select the desired environment name.
Now, you can start triggering the APIs in the collection one by one, following the specified sequence. Proceed to the next API only when the response from the current API is a successful "200" status code.
