The Organization would like to have Heroku like platform - apps deployment made easy with webserver/https auto-configuration. Hosted on-premises. After study phase we recommended CaptainDuckDuck platform, available at github.
What is it?
CaptainDuckDuck is self-hosted platform for developers that wants to focus on developing, not on server ordering, installation, configuration, SSL certs, buildchains, etc.
It supports any language you like (ready to go examples for PHP, Python-Django, Ruby-Rack, NodeJS).
HTTPS made easy.
Simple web interface and command line client available.
Many ways to deploy: upload via dashboard, command line
captainduckduck deploy, github/bitbucket/gitlab/other webhooks.
You can customize nginx if you like (add HTTP/2 support, cache settings, extra headers configuration, you name it).

There are few things you need to take care of before going any further.
Server with public IP
Yes, you need it. Good news is that for a starter you can try Digital Ocean most popular 5$/month droplet (and there are many referrals around the web that will give you 10$ credit, so you can try it for 2 months with no cost). CaptainDuckDuck is well tested with Ubuntu 16.04, so choose this one.
It is also required to have a docker environment ready, so add it during droplet configuration or install it by yourself later.
512MB of RAM may not be enough (since the build process for apps is resource-consuming), so go for 1GB.
Yes, you can try CaptainDuckDuck on your laptop, but we will skip it now.
During installation you will be asked for a wildcard DNS entry (
*.demo.domain.tld). This entry should point to your CaptainDuckDuck IP address.
Well, this should be quick:
# mkdir -p /captain && docker run -v /var/run/docker.sock:/var/run/docker.sock dockersaturn/captainduckduck
You will see some output, after few seconds Captain should be ready at your command at
http://[SERVER_IP_ADDRESS]:3000. You can try it - you can login with default password (
captain42 - it should be displayed on login screen), but do not make any changes yet - you will configure it via command line client.
As noted above, now it’s time to connect DNS name of your choice. This should be wildcard A-record, pointing to your Captain IP address. So
22.214.171.124. Use some online DNS query service with random string (like
randomstring123.demo.domain.tld) to confirm that your changes have been propagated.

Install cmd client on your laptop
Assuming you already have npm environment ready, just run
npm install -g captainduckduck followed by
captainduckduck serversetup. Setup wizard will guide you. After this you can access CaptainDuckDuck at
https://captain.demo.domain.tld, thanks to Lets Encrypt.
Deply test app
You are ready to got for your first app. Go to the Captain in your browser, navigate to Apps and create a new app. Name it
Now you are ready to deploy your test app! Choose something from test apps repository - download, unzip and run
captainduckduck deploy. Remember to enter
my-test-app when asked for app name. After succesful build, you app should be deployed at

You can go to Captain web interface and configure environment variables, web hooks, HTTPS (with one click!) etc…
Yes, there are plenty of predefined applications you can choose from. So it’s possible to deploy wordpress using single click.
