Rancher Desktop on Mac πŸš€

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:

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
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:

Rancher Desktop

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:

Rancher Postgres permission error
