The Complete Guide to Install Tutor Dev Koa Release
In Tutor Dev Koa, mounting is the process of linking a local directory to a path in the Tutor Dev Koa container. This allows you to develop and test your code locally without having to deploy it to the production server. To understand the process of releasing Tutor Dev Koa, you first need to understand why we need to mount files and folders in Tutor Dev Koa. Also, in this blog, you can find how to change or apply a theme in your tutor dev koa Open edX platform.
Why We Need to Mount Files and Folders in Tutor Dev Koa
You need to mount files and folders in Tutor Dev Koa to make them accessible to your Koa application. This can be useful for a variety of reasons, such as:
Serve static files, such as images, CSS, and JavaScript.
Store configuration files.
Share data between different parts of your application.
Develop and test your application locally.
Deploy your application to a production environment.
When you mount a file or folder, it establishes a link between the file or folder on the host machine and the corresponding file or folder within Koa. This enables the Koa application to access the file or folder by utilizing the identical path present on the host machine.
Let’s dive into the process of mounting in the tutor dev koa release.
Mounting Process in Tutor Dev Koa
First of all, we need to check the tutor local - - help command.
$ tutor local - - helpThe command displays help information for the tutor local command, which is used to deploy and manage a local Open edX platform using Docker.

Copy File From Container
To mount files from a container, you first need to copy them from the container to the local system. This can be done with the following command:
$ tutor local bindmount (service_name) (container_path)As an example, we copied the LMS container directory during the mounting process.
$ tutor local bindmount lms /openedx/edx-platform
The same procedure should be followed for other services, such as:
Bindmount LMS Worker
$ tutor local bindmount lms-worker /openedx/edx-platform
Bindmount CMS
$ tutor local bindmount cms /openedx/edx-platform
Bindmount CMS-Worker
$ tutor local bindmount cms-worker /openedx/edx-platform
All mounted services are copied into a single folder called edx-platform, which is located at the below location.
/home/codetrade/.local/share/tutor/volumes/edx-platformThe koa tutor installation creates 3 files, but to save all the mounting we have to create a new file "docker-compose.override.yml" from the terminal:
$ nano "$(tutor config printroot)/env/local/docker-compose.override.yml"In the file, store the services in the following format.
(local-volume-path):(container-path)Use the bash path as the container path and add a bindmount volume path. Similarly, the above process is applied to all containers to mount, such as LMS, LMS-worker, CMS, and CMS-worker.
Check the docker-compose.override.yml file after mounting for the changes as shown below.

Stop and Start the Container
Once the file has been saved, stop the run containers by using the given command:
$ tutor local stopAnd then execute the Start command to run containers
$ tutor local start -dWhen the container file is mounted, we can make any changes we want and save them permanently. All these processes are running for every container mounting like eCommerce, and discovery.
