Docker for mac & local developer environment optimization
1 like2,559 views
Docker can be used to optimize a local development environment by providing the same environment as production. Issues with performance on Docker for Mac can be addressed through techniques like using delegated volume mounts, removing xdebug, and using a solution like mutagen that syncs files without mounted volumes for faster performance. Mutagen provides near native performance, easy setup and monitoring, and works with any dockerized application.
