Docker helps ensure that each developer is running the application with the same version of dependencies and tools.

Due to the nature of containers, Docker solves this problem for free.

When working on a number of projects with conflicting dependencies, it can be difficult and error-prone to isolate one from another.

The act of declaring a Dockerfile or Docker Compose file makes it explicit exactly what dependencies are required for the app to run and how they are wired up.

With Docker and the help of Docker Compose, this can be reduced to a single step.

Setting up a new project can involve a number of steps.

Before we begin, letвЂ™s remind ourselves of a few reasons why we might be developing in Docker: Developing in DockerДeveloping in Docker has a number of advantages over developing directly on your Mac. In this post we are going to explore a common pitfall related to developing an application in Docker on the Mac and see what we can do to mitigate the issue and work as productively as possible. It can simplify both the development of an application as well as deployment and management of it.

This bug has been fixed in an experimental build you can install in case you need it.Docker is a helpful tool for both developers and ops. Virtiofs requires macOS 12.2+ for Apple Silicon and macOS 12.3+ for Intel.ДЄs a final note, interested developers should be aware of a known bug which can make containers running with virtiofs fail due to permission errors.

Specifically, says Docker, the new version reduces by 80%-90% the time taken by operations such as importing 284MB of data into a MySQL database, running composer install for a large PHP codebase, or launch a monolithic TypeScript app.ДЄs mentioned, virtiofs is not enabled by default, but can be enabled under Docker Desktop experimental features.

This is especially useful for lightweight VMs and container workloads, where shared volumes are a requirement.

The goal of virtiofs is to provide local file system semantics between multiple virtual machines sharing a directory tree. The changes introduced in version 4.6 include the adoption of virtiofs as an optional replacement for gRPC-FUSE and greatly improve sharing performance. When considering that modern dependency management can easily bring 10k вЂ“ 100k files into a project (which linearly increases the performance penalty), this can result in poor performance as the host and container keep in sync via the volume. Previous to version 4.6, though, Docker warned developers of a performance hit the bind mounts suffered with very large repositories or programs using many external dependencies.

Bind mounts are the most convenient option to share code that you may need to edit from within the container. Each has its own pros and cons, which makes them best suited for different use cases. According to Docker, the new version may reduce the time taken by file syncing by up to 98%.Д¬ode sharing is one of three approaches Docker Desktop supports for sharing a part of the local file system with a container: bind mount, named volumes, and direct file copy.

Docker Desktop 4.6 for Mac introduces a number of changes that speedВ up file syncing between the macOS host and Docker VM.
