Connect to Redis CLI

$ redis-cli

Enable the current redis as a slave for the master node

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

To remove a submodule you need to:

	FROM ruby:2.3.1

	# Install dependencies
	RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs

	# Set an environment variable where the Rails app is installed to inside of Docker image:
	ENV RAILS_ROOT /var/www/app_name
	RUN mkdir -p $RAILS_ROOT

	# Set working directory, where the commands will be ran:

	#!/bin/bash

	# This is a modification of gitlab-gc.sh script created by Peter Bábics (pbabics/gitlab-gc.sh)

	# Improvements
	# - Searching in all BASE_PATH, not fixing the search to a depth of 2
	# - Directories without valid tags or revisions directories won't be processed (to avoid unexpected issues)
	# - Logging in case there's nothing to delete
	# - running registry-garbage-collect only when something has been deleted

	Put this in your `local-configure.yml` file, add as many users as you need:

	users:
	- name: fulvio
	sudoer: yes
	auth_key: ssh-rsa blahblahblahsomekey this is actually the public key in cleartext
	- name: plone_buildout
	group: plone_group
	sudoer: no
	auth_key: ssh-rsa blahblahblah ansible-generated on default

	#!/bin/bash

	# To run locally: ` curl -s https://gist.githubusercontent.com/jeefy/7fed19a335d5caae24639e7ee7be1b71/raw/install-rancher-compose.sh \| sh `

	VERSION_NUM="0.9.2"

	wget https://github.com/rancher/rancher-compose/releases/download/v${VERSION_NUM}/rancher-compose-linux-amd64-v${VERSION_NUM}.tar.gz
	tar zxf rancher-compose-linux-amd64-v${VERSION_NUM}.tar.gz
	rm rancher-compose-linux-amd64-v${VERSION_NUM}.tar.gz
	sudo mv rancher-compose-v${VERSION_NUM}/rancher-compose /usr/local/bin/rancher-compose

	#!/usr/bin/env node

	// Reads JSON from stdin and writes equivalent
	// nicely-formatted JSON to stdout.

	var stdin = process.stdin,
	stdout = process.stdout,
	inputChunks = [];

	stdin.resume();

	docker logs nginx 2>&1 \| grep "127."
