ASP.NET Core & container:
remotely - registration
 Register on DigitalOcean. You can use my
referral link, if you'd like
https://m.do.co/c/61f8c0f9852c
 Create a droplet
◦ OneClick apps: Dokku
◦ Size: smallest ($5/mo)
◦ Choose region (I personally like Amsterdam)
◦ No additional options (especially IPv6 - there is a
bug with it)
◦ Enter the droplet name
◦ Add key (or create new one)

14. @ysilvestrov
ASP.NET Core & container:
remotely - setup
 Setup Domain
◦ On your DNS provider, add 2 DNS records
 your.domain A DropletIP
 *.your.domain A DropletIP
 open Dokku on http://your.domain
◦ Check the key
◦ Change hostname to your.domain
◦ Check "Use virtualhost naming"
◦ Click Finish setup

15. @ysilvestrov
ASP.NET Core & container:
remotely - tools
 Install tools
◦ Git for Windows
◦ PuTTy
◦ Add your keys to pageant (installed with
PuTTy)
◦ Open your.domain in PuTTy to cache the key

16. @ysilvestrov
ASP.NET Core & container:
remotely - deployment
 Push your app
◦ Open Git Bash shell
◦ cd /c/path/to/your/project/bin/Docker/Release
◦ copy Dockerfile on this level from [projectname] folder
◦ git init
◦ git add .
◦ git commit -m "First commit"
◦ git remote add dokku dokku@your.domain:your-app-
name
◦ git push dokku master
◦ If everything is OK, you should see "=====>
Application deployed: http:/ /your-app-
name.your.domain
◦ Open that URL and enjoi :)

17. @ysilvestrov
Why the heck the Spillikin API is
done using NodeJS?
 Limited DB support (apart from SQL
Server – PostgreSQL + SQLite)
 Too many changes in naming etc. (k =>
web => dotnet)
 Too many changes in interfaces etc.
