C++ Docker CI/CD example

This repository contains minimal example of a WebAPI built with C++ and complete Docker CI/CD support via GitHub actions and DockerHub.

• Multi-Platfrom support with Docker via Buildx/docker/setup-buildx-action and docker/build-push-action
  • In this example, we support linux-x86_64 and linux-arm64, but other options are possible as well. To see the list of available platforms, look at the output of docker/setup-buildx-action and docker/setup-qemu-action in the GitHub action log. Example output: linux/amd64,linux/arm64,linux/riscv64,linux/ppc64le,linux/s390x,linux/386,linux/mips64le,linux/mips64,linux/arm/v7,linux/arm/v6
• Multi-Stage build to achieve minimal application (Docker image) size
• Automatic CI/CD pipeline with GitHub actions
  • Cache Docker builds with GitHub actions
  • Automatic upload to DockerHub

Setup

You need to specify two GitHub Secrets in your project settings after cloning the repository:

• DOCKERHUB_USERNAME: your DockerHub user name
• DOCKERHUB_TOKEN: a DockerHub access token (to create one, go to DockerHub Account settings, Security, Access Tokens)

Adjust the docker-ci.yml and docker-cd.yml and the Dockerfile. Add your own code and configure/build instructions.
