dda-devops-build
dda-devops-build integrates all the tools we use to work with clouds & provide some nice functions around.
Tools we support are
- terraform: for setting up the plain infrastructure around.
- docker: for creating images
- c4k: for generating kubernetes manifests
- provs: for setting up small single-node k3s clusters
- gopass: for credential management on devops computers
- cloud providers: hetzner, digitalocean, aws
In addition we provide a ReleaseMixin for release related tasks like tag / publish & version-bump

Principles we follow are:
- Seperate build artefacts from version controlled code
- Domain Driven Design - in order to stay sustainable
