Migrate Bold BI Application from Linux to Kubernetes.

Introduction

This section explains how to migrate the Bold BI application from a Linux environment to a Kubernetes environment. It is assumed that the Bold BI DB server has public access, either through a Managed instance or a server deployed in an online VM. To migrate the database, you can refer to this article: link. Follow the steps below to migrate the Bold BI instance from Linux to Kubernetes.

Backup Application Data From Deployed Location

Backup the Bold BI app_data folder in a Linux environment from the following location /var/www/bold-services/application.

Restore Application Data to File Share

We need to restore application data files to your file share based on the cloud provider using the following:

EKS Migration

1. Create a new S3 bucket or you use existing S3 bucket for copying app_data from your local machine by following link.
2. Now, run the below command to move app_data to s3 bucket.

   aws s3 cp --recursive <Source folder location> s3://<S3 bucket name>
   

3. Then create EFS and migrate all data’s from S3 bucket to EFS by following link.

   Note : Please use same security group for EKS cluster and EFS file system

4. After creating EFS, use DataSync to migrate all data into EFS. You need to create a task in data sync and set sources file as S3 bucket and Destination files as EFS for DataSync by following link.

AKS Migration

1. Create a file share in a storage account on the Azure resource group by using this link.

2. Restore the app_data data as shown in the screenshot to the root folder path of the file share using the Azure Storage Explorer tool.

   

GKE Migration

1. Create a file store in Google cloud service by using this link.
2. Mount the created file store in VM instance by using this link.
3. Copy the back up app_data folder form VM instance to file store by using thislink.

Deploy Bold BI using the restored file share

1. Deploy the Bold BI application in the EKS/AKS/GKE environment by following this document.

   Note: Use the same file store while crafting the yaml file.

2. Follow these steps if you use a new DNS/IP for the environment. If you are using the same DNS, then you can switch to the next step directly.
   • Navigate to [new DNS]/ums/administration in the browser.
     https://gke-migrate.boldbi.com/ums/administration

     Note: You can use the same Bold BI application login credentials for the new AKS environment.

   • Update the new DNS/IP and enable the checkbox.
     
     
   • After updating the new IP/DNS, save the changes.
   • Restart all pods using the following commands.

     kubectl rollout restart deploy -n <namespace>
     

     Example: kubectl rollout restart deploy -n bold-services
3. Now, the Bold BI application has been completely migrated from Linux to the Kubernetes environment. You can access Bold BI with the same login credentials.
