I am currently working on a project as part of my studies, where Bahmni is being installed on a server running as a virtual machine (VM). During the installation, I encountered an issue: The docker-compose.yml file is configured to install Bahmni in the /var directory. Unfortunately, there isn’t enough storage space available there, which causes the server to crash once the storage is full.
My question is: Is it possible to redirect the installation to a different directory without affecting Bahmni’s functionality? If so, what modifications need to be made in the docker-compose.yml file, and are there any potential risks or considerations I should be aware of?
I would appreciate any help or suggestions!
Could you please answer my question? That would be very kind of you.

Yes, it is possible to redirect the installation to a different directory in your docker-compose.yml file, and this should not affect Bahmni’s functionality, as long as you carefully update the relevant paths and ensure that your system has sufficient storage.
Here are the general steps to modify the installation path:
Identify the Volume Path: In your docker-compose.yml file, look for the volume definitions under the volumes: section.
This volume is probably mapped to /var or /var/lib/docker by default. You can modify it to point to a new location with more available space.
Modify the Volume Path: Change the volume path to your desired location. For example, if you want to change the path to /new/path/to/storage.
Ensure Permissions: Make sure the new directory has the proper permissions to allow Docker to read and write files.
Modify Dockerfile or Container Configurations (if necessary): If Bahmni or its Docker images explicitly reference /var, you may need to adjust those paths inside the Dockerfiles or container configurations to match your new directory. This might involve checking the Docker image setup or consulting the Bahmni installation documentation for specific path configurations.
Potential Risks and Considerations:
Permissions: Make sure the new directory has proper permissions for Docker to manage the files.
Backup and Recovery: Ensure that you have a backup strategy in place for the new storage location.
Docker Storage Driver: Be cautious with the Docker storage driver configuration, as certain drivers may have specific requirements for the file paths.
Disk Space: Ensure that the new directory is on a disk with enough space for Bahmni’s data, especially as the system grows.
System Configuration: Changing directory paths might also require you to update other system configurations to ensure Bahmni operates seamlessly.
