Project structure

  • app - Frontend Node/Webpack application based on Vue.js
  • backups - default location for backup files
  • bin - includes backup and restore scripts
  • cms - the Django/Wagtail CMS backend
  • static - http server component to serve static media files

Run application as a Docker Compose Stack in production

Please be aware, in production proxy server negotiating SSL encryption is needed. An example configuration is included in the docs directory.

Environment

The file .env.example includes example environmental variables. Copy the file as .env as it will be considered by docker-compose during application startup.

Init application

1. Prepare database:

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up db

Wait until database is created and all extensions are installed. Last line should look like:

db_1      | Loading PostGIS extensions into django
db_1      | CREATE EXTENSION

...

PostgreSQL init process complete; ready for start up.
db_1      |
db_1      | 2021-08-07 16:22:57.109 UTC [1] LOG:  starting PostgreSQL 13.3 (Debian 13.3-1.pgdg100+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 8.3.0-6) 8.3.0, 64-bit

db_1      | 2021-08-07 16:22:57.126 UTC [271] LOG:  database system was shut down at 2021-08-07 16:22:56 UTC
db_1      | 2021-08-07 16:22:57.139 UTC [1] LOG:  database system is ready to accept connections

2. IMPORTANT QUICKFIX

Before continuing comment out the following line in cms/src/lis/urls.py ONLY during initial setup:

urlpatterns += i18n_patterns(
    path('api/', include('api.urls')) # <<< bug triggers database queries during migration
)

Revert this change before running the application.

3. Run Migrations

With the database still running, init database schema running Django migrations in a new terminal window:

$ docker-compose -f docker-compose.yml -f docker-compose.dev.yml run cms python manage.py migrate
  1. Create superuser

This user will be the initial superuser to log in to the CMS interface.

$ docker-compose -f docker-compose.yml -f docker-compose.dev.yml run cms python manage.py createsuperuser
  1. Init homepage

Connect to the database via psql client:

$ docker-compose -f docker-compose.yml -f docker-compose.dev.yml exec db psql -U django

And run the following commands to update the default Wagtail homepage to be compatible with the LIS schema:

update wagtailcore_page 
set content_type_id = (
		select id from django_content_type 
		where  app_label = 'cms' and model = 'homepage'
	),
	slug = 'homepage'
where id = 2;

insert into cms_i18npage (page_ptr_id, title_de, title_cs, draft_title_de, draft_title_cs, editor, original_language, temporary_redirect)
values (2, 'Homepage',	'Homepage',	'Homepage',	'Homepage',	'root', 'de', '');

insert into cms__content_pages (i18npage_ptr_id, body, body_de, body_cs)
values (2, '[]', '[]', '[]');

insert into cms_homepage values (2);

Also, there seems to be a bug in django-modelcluster when renaming models that are linked via ParentalManyToMany fields. Update the reference column manually for now:

alter table cms_memorial_site_tag_memorial_type
rename column locationtypetag_id to memorialtag_id;
  1. Finish up

Shut down all running stack components and revert the quickfix.

$ docker-compose down

Running the application stack

Start application for development:

$ docker-compose -f docker-compose.yml -f docker-compose.dev.yml up

Start application for production (creates static build of app component):

$ docker-compose up --build

Backup & restore

# Backup from running containers
$ bin/backup.sh backups/ .env

# restore (timestamp of backup files in backups/ directory)
# !deletes existing data!
$ bin/restore.sh backups/ 2021-08-07-12-43-43 .env

Troubleshooting

Prune renditions

$ docker-compose exec cms python manage.py prunerenditions

Fix Wagtail page tree

$ docker-compose exec cms python manage.py fixtree
