Note:
This is going to be purely technical short post focusing on getting Rancher desktop to work on Mac with Volume fixes!!

Setup Docker tools

 brew install docker docker-compose
Enter fullscreen mode Exit fullscreen mode

After running above commands you will get following commands. Simply execute them:

Enter fullscreen mode Exit fullscreen mode

Setup Rancher Desktop

 brew install --cask rancher
Enter fullscreen mode Exit fullscreen mode

Once setup is done open it & it will look like this:

A sample docker-compose:

 version: '3' services: db: image: postgres:14.4-alpine ports: - '9432:5432' environment: POSTGRES_PASSWORD: docker POSTGRES_USER: docker POSTGRES_DB: postgres PGDATA: /var/lib/pg_data volumes: - ./data:/var/lib/pg_data
Enter fullscreen mode Exit fullscreen mode

It will fail with following error:
