Docker Desktop 4.13.0 is now available for Docker developers to download and install on all the leading platforms - MacOS, Linux and Windows. It comes with the latest Kubernetes v1.25.2, Compose v2.12.0 and Snyk v1.1025.0.
This release introduced a new Docker CLI plugin for the first time called docker dev. The docker dev is a new Dev Environments CLI that lets you create, list, and run Dev Envs via the command line. It means that now it’s damn easier to integrate Dev Envs into custom scripts.
What is Dev Environment?
Dev Environment helps developers to create a configurable developer environment with all the code and tools you need to quickly get up and running. Using Dev Environment, developer can:
- Use a container locally as a full development environment.
- Share code (including dependencies) with your team members in one click.
- Move quickly between branches or run them side by side in VSCode.
Test driving Docker Dev Environment CLI
Ensure that you have the latest version of Docker Desktop 4.13.0+ up and running on your laptop.
