Website of the Swiss Society for Public Health, developed by datalets,ch using the open source, Django-based Wagtail CMS. The frontend is implemented by moving water using Bootstrap framework.
This project is open source under the MIT License.
An easy way to set up your machine could be to use Vagrant, then in the project folder in the terminal type: vagrant up. Then when it is ready, follow instructions for publichealth/static/org/archive-message.html#Database setup. To set up a full development environment using Docker or native components, follow all these instructions.
Frontend setup
Use the LTS version of node.js (we recommend using nave.sh with nave use lts), then:
npm install -g yarn grunt-cli
yarn install
The first command (..install -g..) may require sudo if you installed node.js as a system package.
Static libs
In production we use a build command to copy static libraries into the right location. Currently there is no make script for local development. As a workaround, use this in the root folder to create a symbolic link:
ln -s ../../node_modules/@bower_components publichealth/static/libs
Compilation
Afterwards, to compile the frontend, you should be able to run:
grunt
If you are only working on the frontend, you can start a local webserver and work on frontend assets without the backend setup described below. There is a grunt browser-sync setup for working with frontend assets.
(In a Vagrant shell, use the alias watch)
Backend setup
If not using Vagrant: after installing Python 3, from the project folder, deploy system packages (here shown for Ubuntu users) for the development libraries of Python, libJPEG and libPQ (Postgres Client):
sudo apt-get install python3-dev libjpeg-dev libpq-dev
Create a virtual environment as below:
sudo apt-get install python3-venv
pyvenv env
. env/bin/activate
pip install -U pip
pip install -r requirements.txt
At this point your backup is ready to be deployed.
Once your installation is ready, you can get a blank database set up and add a user to login with.
If you are using Vagrant, enter the shell of your virtual machine now with vagrant ssh
Run these commands:
./manage.py migrate
./manage.py createsuperuser
You will be asked a few questions to create an administrator account.
Starting up
If you have one installed, also start your local redis server (service redis start).
After completing setup, you can use:
./manage.py runserver
(In a Vagrant shell, just use djrun)
Now access the admin panel with the user account you created earlier: http://localhost:8000/admin/
Issues with migrating database tables in SQLite during development? Try ./manage.py migrate --fake

Currently the project has two main production deployment strategies: native and Docker Compose, the latter optionally managed by Ansible. Native is currently the default one. To switch to Docker Compose, change the symbolic Makefile link to point to Makefile.docker-compose or run your make commands as follows:
$ make -f Makefile.docker-compose <command>
This project supports Ansible and Docker Compose for automated deployment. To get started, copy ansible/roles/web/templates/docker-compose.j2 to /docker-compose.yml and fill in all {{ variables }}. This can also be done automatically in Ansible.
To update all roles from Ansible Galaxy used in our install scripts:
ansible-galaxy install `ls ansible/roles -x -I wagtail` --force
To check that the scripts and roles are correctly installed, use this command to do a "dry run":
ansible-playbook ansible/*.yaml -i ansible/inventories/lagoon --list-tasks
If you only want to run a certain set of actions, subset the tags which you see in the output above. For example, to only update the NGINX configuration:
ansible-playbook ansible/web.yaml -i ansible/inventories/lagoon --tags "nginx_template_config"
To do production deployments, you need to obtain SSH and vault keys from your system administrator (who has followed the Ansible guide to set up a vault..), and place these in a .keys folder. To deploy a site:
ansible-playbook ansible/*.yaml -i ansible/inventories/lagoon
For an update release with a specific version (tag or branch), use (the -v parameter showing output of commands):
ansible-playbook ansible/site.yaml -i ansible/inventories/lagoon --tags release -v -e gitversion=<v*.*.*>
You can also use the gitrepo parameter to use a different fork of the source code.
Once the basic system set up, i.e. you have an ansible user in the sudoers and docker group, you are ready to run the playbook.
Start a release with Ansible, then complete it using make, i.e.:
ansible-playbook -i ansible/inventories/lagoon --tags release ansible/wagtail.yaml
ssh -i .keys/ansible.pem ansible@<server-ip> "cd <release_dir> && make release"
This is already part of the normal release cycle, but if you wish to update the Docker images to the latest versions separately, use:
make upgrade
For development, it's handy to have access to a copy of the production data. To delete your local database and restore from a file backup, run:
rm publichealth-dev.sqlite3
python manage.py migrate
python manage.py loaddata publichealth.home.json
You might want to createsuperuser again at this point.
