development environment

summary

  • create folder on server as: repo--dev.git
  • initialize git repo: git init –bare
  • create folder on local machine
  • get files from remote repo: git clone ssh://git@olkn.myvnc.com/repo--dev.git
  • add files to staging: git add -A
  • commit changes to repo: git commit -m ““
  • push changes to remote repo: git push origin

git

config

  • git config –global user.name “olkn”
  • git config –global user.email “olkn@gmail.com”
  • git remote add olkn ssh://olkn.myvnc.com/git/repo-python-development
  • git config –global pull.rebase true
  • git config –global color.ui auto
  • git config –global core.editor vim
  • .gitignore to list all files that should not be included in git repo

initialise git repo

git init

git init –bare : if the repo is on a server and no working tree is necessary (should end in .git)

stage

Staging adds file to a stage prepared for later commit

  • git add -A
  • git stage .

commit

All files in staging were added/committed to the repo

git commit -m “Comment for commit”

password less login

ssh-keygen -t rsa -b 4096 -C “”

ssh-add .ssh/id-rsa

ssh-copy-id -i .ssh/id-rsa @

initialise git repo

mkdir

cd

git init –bare –shared

add files to repo

git add -A

git commit -m “”

add remote repo

git remote add live ssh://@/

git push live

docker

docker build -t : build the given image based on Dockerfile

docker images : list all available docker images in the system

docker run -it : run interactive mode image

docker run -d -p 5000:5000 : run image in daemon mode with ports exposed

docker ps : show all running docker container

docker start/stop : start/stop a container

docker-compose up -d : start docker environment detached

docker-composer down : stop all containers

docker-composer ps : list all running containers

docker-composer build : build images from scratch

docke-compose logs : show the log files for a container

laravel

laravel with sail

  • install docker compose
  • install composer: wget https://getcomposer.org/installer

initialize a new project

curl -s https://laravel.build/project-name?with=mysql,selenium,mailhog |bash

configuration

edit .env

docker composer file

docker-compose.yml

docker-file

programming

python

laravel

alternative

python

  • python3 -m venv
  • source /bin/activate

git

  • git init . (executed in folder of course
  • create .gitignore with contents (*.pyc and __pycache__)

README

create a file README with project description and usage instructions

markdown format (README.md) would be a good choice for the formatting

git commit

  • git add .gitignore README.md
  • git add *
  • git comit -m “initial release”

skeleton

file structure

  • folder docs – program documentation (spinx)
  • folder src/app – source code of the application
  • folder tests – unit test files
  • .gitignore – see above
  • requirements.txt – pip requirements file
  • README.md – see above
  • TODO.md – open issues to implement
  • LICENSE – ???
  • setup.py – see below

program skeleton

structure with functions, classes, modules, etc but with docstrings only as the contents will follow later with the implementation

create the main file, e.g. .py


""" descriptive text"""
import sys

"""definition of constants"""
URL = "https://olkn.myvnc.com"

def main():
""" main entry point for the program """
pass

"""definition of functions"""
def get_url(url):
"""describe function"""
pass

if __name__ == '__main__'
sys.exit(main())

requirements

list all the requirements in a file: pip freeze requirements.txt
