(with virtualenvwrapper)
mkvirtualenv feinstaub-api -p /usr/bin/python3
pip install -r requirements.txt
- install docker and docker-compose
docker-compose up -d- wait
- maybe create a database (if non existent):
docker-compose run --rm web python3 manage.py reset_db
docker-compose run --rm web python3 manage.py migrate
for server installation protocol see:
- copy
feinstaub/settings/production_example.pytofeinstaub/settings/production.py - CHANGE the annotated things. really!
# database
docker run -d --restart=always -v $(pwd)/../feinstaub-db-data:/var/lib/postgres --name feinstaub-db postgres:9.6
# redis
docker run -d --restart=always -v $(pwd)/../feinstaub-redis-data:/data --name feinstaub-redis redis redis-server
# home
docker run -d --name feinstaub-data -v /home/uid1000 aexea/aexea-base

### rebuild, update
./update.sh
512mb on server are not enough. create swap using:
sudo dd if=/dev/zero of=/swapfile bs=1024 count=524288
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
To make the swap reboot persistent add the following line in /etc/fstab:
/swapfile swap swap defaults 0 0
docker exec feinstaub-db pg_dump -Fc -h localhost -v -U postgres feinstaub > feinstaub-backup.sql
even better:
docker run --rm -ti -v `pwd`:/root --link feinstaub-db:db postgres:9.4 pg_dump -U postgres -h db feinstaub -f /root/feinstaub-db.pgdump
get ipaddress of postgres-container:
docker inspect feinstaubapi_db_1 | grep IPAddress
restore database:
pg_restore -C -v -h [ipaddress-of-db-container] -U postgres -d feinstaub feinstaub-backup.sql
add volume mount to db container:
volumes:
- .:/opt/code
and run dump command:
docker-compose run --rm db pg_dump -Fc -h db -v -U postgres feinstaub -f /opt/code/feinstaub-api-db.dump
