On every push to GitHub, GitHub Action can auto-trigger the docker image build and push to Docker Hub. We will be able to see that each push results in a usable image, which enhances the quality of a docker image a lot.
[cAdvisor] (Container Advisor) provides Docker container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects, aggregates, processes, and exports information about running containers. Specifically, for each container it keeps resource isolation parameters, historical resource usage, histograms of complete historical resource usage and network statistics. This data is exported by container and machine-wide.
