Rancher Desktop on Mac 🚀

#rancherdesktop #docker #mac #volumes

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

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

Compose is now a Docker plugin. For Docker to find this plugin, symlink it:
  mkdir -p ~/.docker/cli-plugins
  ln -sfn /opt/homebrew/opt/docker-compose/bin/docker-compose ~/.docker/cli-plugins/docker-compose

Setup Rancher Desktop

brew install --cask rancher

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

It will fail with following error:

Fixing Volume Permissions in Lima Config
Run

touch /Users/${USER}/Library/Application\ Support/rancher-desktop/lima/_config/override.yaml

echo 'mountType: "9p"' >> /Users/${USER}/Library/Application\ Support/rancher-desktop/lima/_config/override.yaml

Quit and Reopen Rancher Desktop
Run:

docker-compose up

And, congratulation!! you have it running. 🎉🎉🚀

What happens under the hood when Node.js works on tasks such as database queries? We will explore it by following this piece of code step by step.
