I use Docker for local development whenever want to be able to spin things up and tear them down quickly. I am familiar with the difference between an container and a virtual machine, as well as what the chroot, namespaces, and control groups do. I can setup hot module reloading with bind mounts, and recently learned about two stage deploys but the extent of my docker knowledge at the moment is just to setup local development. I think it would be very cool to see how Docker is used in the context of something like Kubernetes or other orchestration solution at scale. I have an example of a use case of Docker for one of my learning experiments on my Github, that boots up MongoDB, Elasticsearch and Kibana, and then sets up a pipeline from Mongodb to Elasticsearch for indexing all using Elasticsearch. The app is not functional yet as I have been focusing on client work of late, but enough is there to show I know at least some Docker.
