Deploying

Requirements

• nodeJS 10+
• dotnetcore 2.1+
• docker compose 1.24+

First run or force udpate

You can examine docker-compose.yml before.

Create a .env file in the root of the project folder based on .env.template.js file, fill it with your own values and run

sudo start.sh

This script builds & deploys this system to docker containers. There will be 4 containers: mongo db server, front nginx web-server, back nodeJs api/website server, dotnetcore bot server. Web-server is configured to get & renew SSL Let's encrypt certificate automatically, so there is no need to install it manually (but you can=).

Common usage

# update from git
sudo update.sh

# run containers
docker-compose up

# stop containers
docker-compose stop

Backup & restore

Mongo database is in data/ folder. You can either save it directly or use these commands

mkdir -p backup
# backup
mongodump --uri mongodb://user:[email protected]:27017/chineseDuck --archive=backup/chineseDuck.archive
# restore with overwriting
mongorestore --uri mongodb://user:[email protected]:27017/chineseDuck --archive=backup/chineseDuck.archive --drop

You have to mongo 4.1+ installed

Local running

# just run
npm run build-dev-run
dotnet src/bot/chineseDuck.BotService/bin/Debug/netcoreapp2.1/ChineseDuck.BotService.dll

# tests
npm run test
npm run test-client

The tests use in-memory db, so you don't need to configure them at all. If the tests exit immediately after the start, try to install libcurl3. Examine Travis CI configuration file .travis.yml for details.
