I’ve been working away for weeks now on my project demo - as part of it I bought a jekyll site template which comes with it’s own dockerfile - I can’t be bothered maintaining both a dockerfild and the circle ci yaml separately. Can anyone recommend a way to just keep using the dockerfile and a Makefile?
Sure, if you can tell us what your CircleCI config and your Dockerfile do. Would you post them here?
You will always need a minimal CircleCI config, but you can certainly do a Docker build inside your build server.
Thanks @halfer - it’s really basic - just builds/serves a jekyll site - currently hosted on github but I’d like to play with deploying it to kubernetes.

```@halfer - I haven’t even approached the circleci config yet - I just saw a sea of yaml and couldn’t figure out from the docs how I could get it to use the Dockerfile.
It’s just using Docker pretty much as you would locally - pull the repo, install Docker, do a docker build, then do a docker run if required. Here is an example:
Yep, and you’re welcome. The CircleCI config then is just a question of keeping up to date with Docker/Compose, and otherwise does not really need to change.
