How to speed up Docker on MacOS

Problem: Containerization is a feature of the Linux kernel (namespaces + cgroups + chroot) and so MacOS and Windows must run a virtualized Linux environment to use Docker, which has a significant performance penalty.
Solution: To help mitigate this issue, Docker (the company) has some recommended configuration tweaks for optimizing performance on MacOS:
Step 1. In Docker Desktop Settings > General > Choose file sharing implementation for your containers. Select VirtioFS and restart Docker Desktop.
Step 2. If youโre using any bind mounts, add the delegated
option when you specify the mount source and destination in the docker-compose.yml
file, for example:
my-service:
image: my-image
container_name: my-container
volumes:
- ./my-app:/app:delegated # this is the relevant setting
