ssh-copy-id -n root@192.248.158.136

The -n is for a dry run.

This will copy the public key allowing us to connect to the server with our private key.

ssh-copy-id root@192.248.158.136

However we need our private key on the box to talk to the private github reppo.

scp id_rsa root@192.248.158.136:/root/.ssh/

Make a directory in the traditional location

mkdir -p /var/www

Pull across blank repo

git clone git@github.com:cleverberry/docker-django-evilsaint.com.git  /var/www/django

I am not going to pull across the existing project as I will need to files as I convert this.

root@docker-django-evilsaint:~# cd /tmp/
root@docker-django-evilsaint:/tmp# git clone git@github.com:cleverberry/django-evilsaint.com

# pull the official base image
FROM python:3.8.3-alpine

# set work directory
WORKDIR /usr/src/django-app

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# install dependencies
RUN pip install --upgrade pip
COPY ./requirements.txt .
RUN pip install -r requirements.txt

# copy project
COPY . .

So, we started with an Alpine-based Docker image for Python 3.8.3. We then set a working directory along with two environment variables:

PYTHONDONTWRITEBYTECODE: Prevents Python from writing pyc files to disc (equivalent to python -B option)

PYTHONUNBUFFERED: Prevents Python from buffering stdout and stderr (equivalent to python -u option)

Next I want to create a directory for me to put my app files into.

mkdir /usr/src/django-app
cp /tmp/django-evilsaint.com/app /usr/src/django-app

Let’s go back to our project root and have a look at what we have.

Next, we need to add a docker-compose.yml file to the project root:

version: '3.7'

services:
  web:
    build: ./app
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - ./app/:/usr/src/django-app/
    ports:
      - 8000:8000
    env_file:
      - ./.env
````


We have created a volume as per the Django app directory we created earlier. This is where we will dump our app source

• ./app/:/usr/src/django-app/

Next we have specified an environmental file

-./.env

Here is what I have placed in mine

DEBUG=True SECRET_KEY=sdiofujsdioaaiWfjRsdTlHjriloarejtiop9dfjuaopjkfiopsdhujZfopieqriarosdXhfpAAsaofkcikoSaSshfgopiswujrfopsdhjiuagTUOphtsudjfiLGHNFohiqeprtghejrfds DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 [::1] SQL_ENGINE=django.db.backends.postgresql_psycopg2 SQL_DATABASE=the_evilsaint_com_034998jer903203ksldjsl SQL_USER=mysaint SQL_PASSWORD=iloveyou_abc123_princess_princess SQL_HOST=localhost SQL_PORT=5432

So now we reference these in the settings and fill in some defaults

Edit the settings file inside this path

nano /usr/src/django-app/

This will become your database block

DATABASES = { “default”: { “ENGINE”: os.environ.get(“SQL_ENGINE”, “django.db.backends.sqlite3”), “NAME”: os.environ.get(“SQL_DATABASE”, os.path.join(BASE_DIR, “db.sqlite3”)), “USER”: os.environ.get(“SQL_USER”, “evilsaint”), “PASSWORD”: os.environ.get(“SQL_PASSWORD”, “!5_V3ry_53cur3”), “HOST”: os.environ.get(“SQL_HOST”, “localhost”), “PORT”: os.environ.get(“SQL_PORT”, “5432”), } }

See how these are used for the remaining variables.

Using the psycopg2 package we need to add some dependencies to our docker file. 

install psycopg2 dependencies

RUN apk update \ && apk add postgresql-dev gcc python3-dev musl-dev ```
