This repository provides a Dockerfile to create a container image mainly used for CI testing of C/C++ programs on Fedora.

The image is rebuilt nightly to ensure it always has the latest packages.

development happens on [this Gitea instance](https://git.dotya.ml/wanderer/docker-fedora-cpp)

## Purpose
* testing c/cpp programs in CI without the need to install all of the deps (such as protobuf, capnproto, pcap, boost, etc...) all the time.  
  found out that if there's enough deps it can actually take more time to pre-configure the environment than downloading a single image once reusing it for all subsequent CI builds.
