Docker Cli Tips and Tricks

My favorite command line options and best practices

Bash/zsh completion
use Tab to populate command line, narrows down options as you go, fills in container names, ID's, images, volumes. Huge time saver.

What is Redis?
Redis is an open source, advanced in-memory key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

######1. If you're running OS X, install redis in terminal using Homebrew : brew install redis

######2. Add the redis and hiredis gems to the project's Gemfile (remember to bundle install after you do this) :

	function useSelectors(reducer, mapStateToSelectors) {
	const [state] = reducer;
	const selectors = useMemo(() => mapStateToSelectors(state), [state]);
	return selectors;
	}

	function useActions(reducer, mapDispatchToActions) {
	const [, dispatch] = reducer;
	const actions = useMemo(() => mapDispatchToActions(dispatch), [dispatch]);
	return actions;
