Public Health Schweiz
|
|
=====================
|
|
|
|
Website of the [Swiss Society for Public Health](http://public-health.ch), developed by [datalets,ch](http://datalets.ch) using the open source, [Django](https://www.djangoproject.com/)-based [Wagtail CMS](http://wagtail.io). The frontend is implemented by [moving water](http://www.movingwater.ch/) using [Bootstrap](https://getbootstrap.com) framework.

## Development environment
|
|
|
|
The easiest way to set up your machine would be to use [Vagrant](https://vagrantup.com), then in the project folder in the terminal type: `vagrant up`. Then when it is ready, follow instructions for *publichealth/static/org/archive-message.htmlDatabase setup*.
|
|
|
|
To set up a full development environment, follow all these instructions.
|
|
|
|
**Frontend setup**
|
|
|
|
If not using Vagrant, you will need to have Ruby and SASS installed on your system, e.g.:
|
|
|
|
```
|
|
sudo apt-get install ruby-sass
|
|
```
|
|
|
|
Make sure a recent version of node.js (we recommend using [nave.sh](https://gipublichealth/static/org/archive-message.htmlthub.com/isaacs/nave)), then:
|
|
|
|
```
|
|
npm install -g bower grunt-cli
|
|
npm install
|
|
bower install
|
|
```
|
|
|
|
The first command (`..install -g..`) may require `sudo` if you installed node.js as a system package.
|
|
|
|
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. Mock content is at `mockup`, and there is a `grunt browser-sync` setup for working with frontend assets.
|
|
|
|
**Backend setup**
|
|
|
|
If not using Vagrant: after installing Python 3, from the project folder, deploy system packages and create a virtual environment as detailed (for Ubuntu users) below:
|
|
|
|
```
|
|
sudo apt-get install python3-venv python3-dev libjpeg-dev
|
|
|
|
pyvenv env
|
|
. env/bin/activate
|
|
|
|
pip install -U pip
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
At this point your backup is ready to be deployed.
|
|
|
|
## Database setup
|
|
|
|
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/
|
|
|
|
## Troubleshooting
|
|
|
|
- Issues with migrating database tables in SQLite during development? Try `./manage.py migrate --fake`
|
|
|
|
## Production notes
|
|
|
|
We use [Ansible](https://www.ansible.com) and [Docker Compose](https://docs.docker.com/compose/reference/overview/) for automated deployment.
|
|
|
|
To use Docker Compose to deploy the site, copy `ansible/roles/web/templates/docker-compose.j2` to `/docker-compose.yml` and fill in all `{{ variables }}`. This is done automatically in Ansible.
|
|
|
|
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 -s ansible/<*.yaml> -i ansible/inventories/production
|
|
```
|
|
|
|
For an update release with a specific version, use:
|
|
|
|
```
|
|
ansible-playbook -s ansible/site.yaml -i ansible/inventories/production --tags release -e gitversion=<v*.*.*>
|
|
```
|
|
|
|
We use a StackScript to deploy to Linode, the basic system set up is to have a user in the sudoers and docker group, and a few basic system packages ready.
|
|
|
|
For example, on Ubuntu:
|
|
|
|
```
|
|
apt-get install -q -y zip git nginx python-virtualenv python-dev
|
|
```
|
|
|
|
The order of deployment is:
|
|
|
|
- docker.yaml (base system)
|
|
- node.yaml
|
|
- site.yaml
|
|
- harden.yaml
|
|
- certbot.yaml
|
|
|
|
The last line adds support for Let's Encrypt, which you can configure and enable (updating your Nginx setup) with:
|
|
|
|
```
|
|
sudo /opt/certbot/certbot-auto --nginx certonly
|
|
```
|
|
|
|
If you do **not** wish to use SSL, delete the last part of your nginx site configuration (/etc/nginx/sites-enabled/...).
|
|
|
|
### Production releases
|
|
|
|
For further deployment and system maintenance we have a `Makefile` which automates Docker Compose tasks. This should be converted to use [Ansible Container](http://docs.ansible.com/ansible-container/getting_started.html). In the meantime, start a release with Ansible, then complete it using `make`, i.e.:
|
|
|
|
```
|
|
ansible-playbook -s ansible/site.yaml -i ansible/inventories/production --tags release
|
|
ssh -i .keys/ansible.pem ansible@<server-ip> "cd <release_dir> && make release"
|
|
```
|
|
|
|
### Restoring a data backup
|
|
|
|
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.
