Explanation

Both Vagrant and Docker can share directories from the host file system to a guest. This allows the guest to access files and folders from the host without copying them. Vagrant uses the config.vm.synced_folder option in the Vagrantfile to specify the shared folders. Docker uses the - v or --volume flag in the docker run command to mount a host directory as a data volume in the Both Vagrant and Docker can download required base images. Base images are the starting point for creating a guest environment. Vagrant uses the config.vm.box option in the Vagrantfile to specify the base image to use. Docker uses the FROM instruction in the Dockerfile to specify the base image to use. Both Vagrant and Docker can download base images from public repositories or local sources. Both Vagrant and Docker can apply changes to a base image. Changes are modifications or additions to the base image that customize the guest environment. Vagrant uses provisioners to run scripts or commands on the guest after it is booted. Docker uses instructions in the Dockerfile to execute commands on the base image and create a new image. Both Vagrant and Docker can save the changes to a new image or discard them after the guest is destroyed. Vagrant and Docker differ in how they start system images. Vagrant starts system images as virtual machines by default, using a provider such as VirtualBox, VMware, or Hyper-V. Docker starts system images as containers by default, using the native containerization functionality on macOS, Linux, and Windows. Containers are generally more lightweight and faster than virtual machines, but less secure and flexible.
