DevOps Questions:
1. How to pass to a `docker build` command arguments at build-time? (Define in Dockerfile: ARG and call `–build-arg =`)
2. What's the difference between Deployment and DaemonSet (Daemon set can create Pod per each Node)
a. Examples of Daemon set deployment (Distributed Storage as as Software solutions, ex. Prometheus, Grafana)
