This is some what of a docker in docker setup.
You have to have this container which hosts the C++ Insights Web Frontend part and the container which contains the C++ Insights binary. Both installed on your local machine.
Then run make get to download the latest pre-built docker image from DockerHub as well as the required cppinsights-container.
Alternatively you can build the image yourself, as GitHub Actions do. Run make build to get all the resources and build the docker image of this repo. You have to take care of build
the image of the C++ Insights docker.
After either of these two steps, you can run make start to start the web part. Give it a few seconds to boot up. After that C++ Insights is
reachable under 127.0.0.1:5000.
You can see what is going on with make logs and stop the container with make stop
The setup is based in this blog post. The
docker container of this repo gets the docker socket of your local machine as well as the /tmp folder mapped into the
running container. With that it can access the image on you local machine (which should contain the cppinsights-container)
