Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

So you want to restart your passenger standalone app

cd path/to/app && ./bin/passenger-config restart-app .

This works until you have multiple passenger apps...

./bin/passenger-config restart-app .

	# Example based on https://github.com/thinkbeforecoding/dddeu-2023-deciders/blob/main/run.fsx

	require "bundler/inline"

	gemfile do
	source "https://rubygems.org"

	gem "minitest"
	gem "decide.rb", "~> 0.4.1"
	end

	# gruvbox-light colorscheme for kitty

	foreground #3C3836
	background #FBF1C7
	selection_foreground #FBF1C7
	selection_background #3C3836

	color0 #FBF1C7
	color8 #928374

	# config/application.rb

	module MyApp
	class Application < Rails::Application
	config.my_setting = "prod value"
	end
	end

	# this won't work

	terraform {
	backend "s3" {
	bucket = "${var.bucket}"
	dynamodb_table = "${var.dynamodb_table}"
	# reminder of the config...
	}
	}

	server {
	listen 80;

	server_name es.example.com;
	return 301 https://$host$request_uri;
	}

	server {
	listen 443 ssl http2;

	#!/bin/bash -e

	if [ ! -f .phantomjs/2.1.1/x86_64-linux/bin/phantomjs ]; then
	curl -k -L -o phantomjs.tar.bz2 http://ci.monterail.io/files/phantomjs-2.1.1-linux-x86_64.tar.bz2
	tar -jxf phantomjs.tar.bz2
	mkdir -p .phantomjs/2.1.1/x86_64-linux/bin
	mv phantomjs-2.1.1-linux-x86_64/bin .phantomjs/2.1.1/x86_64-linux/
