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
|
|
|
|
An easy way to set up your machine could 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.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](https://gipublichealth/static/org/archive-message.htmlthub.com/isaacs/nave) 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. 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.
|
|
|
|
## 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`
|
|
|
|
Trouble installing packages with npm or yarn? Add IPv6 addresses to your hosts:
|
|
|
|
2606:4700:10::6814:162e nodejs.org
|
|
2606:4700::6810:1823 registry.npmjs.org
|
|
2606:4700::6810:1123 registry.yarnpkg.com
|
|
2a0a:e5c0:2:10::8c52:790a codeload.github.com

## Production notes
|
|
|
|
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>`
|
|
|
|
### Deployment with Ansible and Docker Compose
|
|
|
|
This project supports [Ansible](https://www.ansible.com) and [Docker Compose](https://docs.docker.com/compose/reference/overview/) 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](https://docs.ansible.com/ansible/latest/reference_appendices/galaxy.html) 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.
|
|
|
|
### Production releases
|
|
|
|
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`
|
|
|
|
### 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.
