Teamcity (CI), ASP.Net 5, via Docker on Linux PT(1)


Recently I’d set myself the challenge of developing and deploying applications via docker on Linux. An odd challenge yet rewarding!

This series will focus on ultimately how I managed to achieve this and also document some of the pitfalls I fell victim to on the journey.

What I’m attempting here is very much prerelease and is subject to change with some issues being focussed on specific version(s) of frameworks and applications.

Goals :

  • Everything runs / built on Linux, but continues to be cross platform.
  • Everything managed and deployed within docker.

Disclaimer : I’m a complete noob in the Linux world, what I’ve done probably isn’t 100% ideal but hey it works 🙂

Part one… How do I manage all this infrastructure?

The first piece of the puzzle is an excellent containerisation technology called “Docker”. Currently it’s purely in the non windows space but come 2016 windows will have a compatible offering.

If this is completely new I’d suggest spending a few minutes looking around :

Not being keen on managing everything via bash in Ubuntu, it was time to look for platform to assist. This tool was Rancher.

Rancher allows servers across any provider to be treated as one via an overlay network. It’s firmly aimed at managing application stacks and I love it! Needless to say I’ll be migrating everything I run onto this platform. Rancher is easy, clear and well thought out.

With this in mind I needed somewhere to host and I settled on Digital Ocean (Use the promotion code ACTIVATE10 for $10 credit) .

Account created I followed this article Multinode deployments with docker.

Upon completion this screen should greet you:


In the next post I’ll focus on installing team city as a build server.
