** Requirements
Before getting started make sure you have git, docker and docker-compose installed on your machine.
The simplest way to setup this site is to use docker-compose so please install that from this site 
https://docs.docker.com/engine/installation/ 
and make sure the quick start guide works 
https://docs.docker.com/machine/get-started/ 
then you can use the commands below to test and make changes.

** Setup
Steps to get the site running for the first time

*** First clone the project
To get started checkout the project to your machine, with the command below.

#+BEGIN_SRC sh
git clone https://github.com/maidstone-hackspace/maidstone-hackspace-website.git
#+END_SRC

*** Build your containers to install the sites requirements
Once checked out build your containers locally you only need to do this when first start or if requirements change.

#+BEGIN_SRC sh
docker-compose -fdev.yml build
#+END_SRC

*** Start your new containers containing a database and django

#+BEGIN_SRC sh
docker-compose -fdev up
#+END_SRC

Test django is serving pages
http://127.0.0.1:8180

*** Run migrations to setup the database
To run django commands just prefix them with =docker-compose -f dev.yml run django=
#+BEGIN_SRC sh
docker-compose -f dev.yml run --rm django python manage.py makemigrations
docker-compose -f dev.yml run --rm django python manage.py migrate
#+END_SRC
*** Create the admin user.
Once created you can login at http://127.0.0.1:8180/trustee
#+BEGIN_SRC sh
docker-compose -f dev.yml run --rm django python manage.py createsuperuser
#+END_SRC

*** Generate dummy data
#+BEGIN_SRC sh
docker-compose -f dev.yml run --rm django python manage.py generate_test_data
#+END_SRC
** Migrations / Managing default data
If you want to export some data you entered into the admin area you can use =dumpdata= and =loaddata= to export and import.

#+BEGIN_SRC sh
docker-compose -fdev.yml run --rm django python manage.py dumpdata feeds > mhackspace/feeds/fixtures/defaults.json
docker-compose -fdev.yml run --rm django python manage.py loaddata mhackspace/feeds/fixtures/defaults.json
#+END_SRC

** Django Commands

#+BEGIN_SRC sh
docker-compose -fdev.yml run --rm django python manage.py list_subscriptions
#+END_SRC

*** Render image variations, if you change the images sizes this will be needed
#+BEGIN_SRC sh
docker-compose -fdev.yml run --rm django python manage.py rendervariations 'blog.Post.image' --replace
#+END_SRC
** Api
#+BEGIN_SRC python
import requests 

url = 'http://127.0.0.1:8180/api/v1/rfidAuth/'
data = {
  'rfid': '4996',
  'device': '7bff6053-77ef-4250-ac11-8a119fd05a0e'
}

# client = RequestsClient()
response = requests.post(
    'http://127.0.0.1:8180/api/v1/rfidAuth/',
    data={'rfid': '238e', 'device': 'e8f27231-8093-4477-8906-e5ae1b12dbd6'})
#requests.get(url)
return response.status_code

#+END_SRC

#+RESULTS:
: 200
** Server 
Example service setup for website under docker, nginx in a container forwarding traffic to uwsgi.
*** nginx web server
#+BEGIN_SRC bash
docker volume create --name=sockets
docker run --name=nginx -d \
    -v /etc/nginx/sites-enabled/:/etc/nginx/sites-enabled/ \
    -v /etc/letsencrypt/:/etc/letsencrypt/ \
    -v /var/www/:/var/www/ \
    -v sockets:/data/sockets -p 80:80 -p 443:443 olymk2/nginx 
#+END_SRC
*** letsencrypt cert setup
Setup / create new certs
#+BEGIN_SRC bash
letsencrypt certonly --renew --webroot -w /var/www/.well-known -d stage.maidstone-hackspace.org.uk
letsencrypt certonly --webroot -w /var/www/.well-known -d stage.maidstone-hackspace.org.uk
#+END_SRC

Automation of renewal process
create a file called =/etc/cron.monthly/letsencrypt-renew.sh= and make it executable with chmod +x, then place your above commands in the file like in the example below. 
#+BEGIN_SRC bash
#!/bin/bash
letsencrypt certonly --webroot --renew-by-default --agree-tos -w /var/www/.well-known -d stage.maidstone-hackspace.org.uk
#+END_SRC

*** Postgres tips

#+BEGIN_SRC bash
docker-compose -fstage.yml run --rm postgres psql -U postgres
#+END_SRC

*** Backups
Create a backup file with today's date
#+BEGIN_SRC bash
    docker exec -t {CONTAINER_NAME} pg_dump -Fp -c -U postgresuser > dump_`date +%d-%m-%Y"_"%H_%M_%S`.sql
    docker exec {CONTAINER_NAME} bash -lc 'pg_dump --format custom vmdb_production' > dump_`date +%d-%m-%Y"_"%H_%M_%S`.pgdata
#+END_SRC

Import previously made backup
#+BEGIN_SRC bash
docker exec -i -u {USER} {CONTAINER_NAME}  pg_restore --verbose --no-acl --no-owner --clean --role=postgres -Upostgres --dbname={DATABASE_USER} < dump_31-01-2018_13_09_24.pgdata
  docker exec -i -u {USER} {CONTAINER_NAME} pg_restore -C --clean -d {DATABASE_USER} < dump_31-01-2018_13_09_24.pgdata
  cat dump_27-01-2018_14_26_09.sql | docker exec -i {CONTAINER_ID} psql -U postgres
