Listing pods with kubectl get pods, then select a pod name and copy paste it into kubectl logs [pod name]
Once upon a time…
I once took notes (almost sentence by sentence with not much editing) about the architectural design concepts - Command and Query Responsibility Segregation (CQRS) and Event Sourcing (ES) - from a presentation of Greg Young and published it as a gist (with the times when a given sentence was heard).
I then found other summaries of the talk and the gist has since been growing up. See the revisions to know the changes and where they came from (aka the sources).
It seems inevitable to throw Domain Driven Design (DDD) in to the mix.

When unsing docker compose you can have a problem with the order of dependent linked containers
The solution is to start a script which tries to access a service and waits until it gets ready before loading your program

| console.log(window); // log the "window" object to the console |
