Starship is a really nice, fast, customisable shell prompt - of which there are many - but Starship supports a very wide range of things out-of-the-box.
Including docker context’s. It detects Dockerfile and docker-compose.yml/yaml in the directory, and if you’re not on the default context then it’ll show the name of the context you’re on in blue alongside a little whale icon. A tiny but very useful feature.
Better late than never. The one thing I like about is customizability, speed and ability to look same for bash, zsh or fish.
