This is a collection of commands and resources that were useful for me with the initial setup of my MacBook.

• Installs Xcode Command Line Tools

xcode-select --install

• Generate SSH key and add it to the ssh agent
• Homebrew https://brew.sh/
• Oh my zsh https://ohmyz.sh/
• nvm https://github.com/nvm-sh/nvm#git-install
• Install Docker Desktop https://docs.docker.com/desktop/mac/install/
• Rectangle: Move and resize windows in macOS using keyboard shortcuts or snap areas https://rectangleapp.com/
• Add some shell aliases. I can't work without these:

alias g='git'
alias gc='git checkout'
alias gco='git commit'
alias gs='git status'
alias gp='git pull'

alias dc='docker-compose'
alias up='docker-compose up'
alias down='docker-compose down'

With htmx is possible to build dynamic Webapps without REST-APIs and JavaScript. Just simple Django views that returns html.

You can learn more about it in this interesting Django chat podcast episode with the htmx creator Carson Gross.

I really like the idea and I wanted since a while to try htmx working together with Django and finally, I managed to work on that. I created this repository with some implementations with Django of the code examples from the htmx docs page.

**Update: **also this website has some htmx magic on it. For example the post pagination or the search function are built with htmx.

This demonstrates how to use a variable as image for the Dockerfile FROM statement.

Given this docker-compose.yml / Dockerfile setup:

docker-compose.yml

version: '3'
services:
	postgres:
	    build:
	      context: .
	      dockerfile: ./compose/postgres/Dockerfile
	    volumes:
				- postgres_data:/var/lib/postgresql/data
	    env_file:
	      - .env
volumes:
    postgres_data:

Dockerfile

FROM postgres:12.3

The Postgres service will always use the same FROM image defined in the Dockerfile. If we want instead to set the FROM image using a variable, we can do the following:

Docker-compose.yml

• pass a build_image arg with a default value

version: '3'
services:
	postgres:
	    build:
	      context: .
	      dockerfile: ./compose/postgres/Dockerfile
	      args:
	       build_image: "${BUILD_IMAGE:-postgres:12.3}" 
	    volumes:
				- postgres_data:/var/lib/postgresql/data
	    env_file:
	      - .env
volumes:
    postgres_data:

Dockerfile

• use the passed build_image arg in the FROM statement

# this will be the default image
ARG build_image="postgres:12.3"

# The default image will be overriden if other build image is passed as ARG
ARG build_image=$build_image
FROM $build_image

.env

• Pass the desired value in .env

BUILD_IMAGE=postgis:9.6
