Step 3: Get the IP Address of your host computer.Step 2: Build and run the container using the Nginx image.Step 1: Let’s make a directory where we will mount with the container.This blog will teach you how to share data between a Docker containerized application and the host computer. These are Docker volumes and bind mounts. Therefore, the data cannot be readily transferred to another location.ĭocker provides two ways for containers to save files on the host system so that the files are persistent even after the container is shut down. The container’s writable layer is closely connected to the host computer on which the container is executing. Once the container is no longer running, the data does not persist. In this case, the host and the application are running on different infrastructures.Īt times you may want your virtually containerized application to share data and files directly from the host computer.īy default, all files generated within a container are saved on a writable container layer. This means when you virtualize an application, all its data will be hosted within the dockerize containers. Once such application is containerized, the application virtualized data are isolated from the host. This creates an isolated environment for running your application away from the host machine.ĭocker engine takes the role of assigning resources from the host to the virtualized isolated application. Nevertheless, Docker runs on a virtualization architecture.
One reason Docker is superb is due to its ability to containerize an application without installing additional dependencies on your local computer.
