• To create the Docker volume, on the host:

  Code Block
  docker volume create <volume name>

When running the container, the volume is mounted using the -v switch. The syntax for this switch is:

-v <volume name>:<path to mount>

Establishing database file

After the first time python3 manage.py migrate has been run,

• Transfer the db.sqlite3 file to the mounted volume.

• Delete the db.sqlite3 file from its default location at the project root folder.

• Create a symlink at the project root folder called db.sqlite3 that points to the file on the mounted volume.

Database connection using entrypoint.sh

It is recommended that the entrypoint.sh script is used to establish the database connection. The general sequence in the entrypoint.sh script to connect the database on the volume is:

• Run makemigrations/ migrate. This creates a db.sqlite3 database file in its default location in the project root folder.

• Delete the db.sqlite3 file from the project root folder.

• Create a symlink to the database folder.

Here is an example of an entrypoint.sh script:

#!/bin/bash

# Ensure the log directory exists
mkdir -p /var/log/django

# Redirect stdout and stderr to the log file
exec >> /var/log/django/entrypoint.log 2>&1

python3 manage.py makemigrations
python3 manage.py migrate

rm /opt/ece_li_scheduling/db.sqlite3
ln -s /var/lib/ece_li_scheduling/db.sqlite3 /opt/ece_li_scheduling/db.sqlite3

python3 manage.py runserver 0.0.0.0:8000
