How To Share Data Between the Docker Container and the Host

Docker containers are a popular tool for software developers and system administrators. They are lightweight, portable, and easy to deploy. However, one common challenge when using Docker containers is sharing data between the container and the host machine.

In this tutorial, we will show you how to share data between the Docker container and the host machine using Docker volumes.

Step 1: Create a Docker Volume

The first step is to create a Docker volume that will be used to store the data. To create a Docker volume, run the following command:

docker volume create my-data

This will create a Docker volume named my-data. You can check that the volume was created by running the following command:

docker volume ls

Step 2: Start a Docker Container with the Volume

Now that you have created a Docker volume, you can start a Docker container that will use this volume to store its data. To do this, run the following command:

docker run -d -v my-data:/data my-image

This will start a Docker container using the my-image image and map the /data directory inside the container to the my-data volume on the host machine.

Step 3: Access the Shared Data

You can now access the shared data from both the Docker container and the host machine. To access the shared data from the Docker container, simply navigate to the /data directory inside the container. To access the shared data from the host machine, navigate to the directory where the Docker volume is mounted.

Conclusion

In this tutorial, we showed you how to share data between the Docker container and the host machine using Docker volumes. By using Docker volumes, you can easily share data between the two environments without the need for complex configurations or additional tools.
