Container runtime configuration

The basic command to run the Docker container on port 8000 looks like this:

$ docker run -d -p 8000:80 -t ghcr.io/djaodjin/djaopsp/livedemo:main

The container is meant to be run behind a DjaoApp Web/API Gateway for user authentication and permission checks.

When accessed directly, the mockup accounts to login (see settings.DEPLOYUTILS['MOCKUP_SESSIONS'']) are:

“donny”, a profile manager of the site (broker)
“kathryn”, a profile manager of an alliance profile on the site.
“alice”, a profile manager of an organization member of the alliance above.
“steve”, a profile manager for an organization with no special affiliations.

Using a local database

The djaopsp Docker container is meant to be started with a site.conf and credentials configuration files. Typically site-specific configurations, like feature flags, pathnames and URI location of third-party services are stored in site.conf, whereas identification and encryption keys are stored in the credentials file.

To keep things simple, we are going to create the database and site.conf configuration file in a directory on the local filesystem.

$ mkdir -p mounted_config

We can create such database by running the commands:

$ python manage.py migrate --run-syncdb
$ python manage.py createsuperuser
$ mv db.sqlite3 mounted_config

With a db.sqlite3 file created, we then create a site.conf configuration file and define the necessary variables to use our newly created database.

We are going to mount the host directory where the database resides as /app/var in the container, so we set DB_ENGINE and DB_NAME as such:

$ cat mounted_config/site.conf
...
DB_ENGINE="django.db.backends.sqlite3"
DB_NAME="/app/var/db.sqlite3"

Now when we start the container, we mount the host directory where the database and configuration file reside, as we define the environment variable DJAOPSP_SETTINGS_LOCATION to find such configuration files.

$ sudo docker run -d -p 8000:80 -v "${PWD}"/mounted_config:/app/var:z -e DJAOPSP_SETTINGS_LOCATION=/app/var -t ghcr.io/djaodjin/djaopsp/djaopsp:main

Configuring the SMTP settings to send email

If you have setup a local database as explained in the previous section, you will guess correctly that we define the e-mail settings in site.conf.

For example, if we want to use the Django internal in-memory SMTP server instead of an actual SMTP server, thus preventing both 500 errors because of SMTP misconfiguration and e-mails ending up in an inbox, we can use the following definitions:

$ cat mounted_config/site.conf
...
EMAIL_HOST    = "localhost"
EMAIL_PORT    = 1025    # matches SMTP_PORT in test driver
EMAIL_USE_TLS = False
EMAIL_BACKEND = 'django.core.mail.backends.locmem.EmailBackend'

Then, as usual, we start the Docker container as:

$ sudo docker run -d -p 8000:80 -v "${PWD}"/mounted_config:/app/var:z -e DJAOPSP_SETTINGS_LOCATION=/app/var -t ghcr.io/djaodjin/djaopsp/djaopsp:main

Configuring where assets are stored

$ cat mounted_config/site.conf
...
DEFAULT_FILE_STORAGE    = "storages.backends.s3boto3.S3Boto3Storage"
AWS_STORAGE_BUCKET_NAME = "*bucket_name*"

Then, as usual, we start the Docker container as:

$ sudo docker run -d -p 8000:80 -v "${PWD}"/mounted_config:/app/var:z -e DJAOPSP_SETTINGS_LOCATION=/app/var -t ghcr.io/djaodjin/djaopsp/djaopsp:main

Reference for configuration variables

There exists templates for both credentials and site.conf in the source repository inside the etc directory.
