# https://docs.docker.com/compose/yml/
# Each service defined in docker-compose.yml must specify exactly one of
# image or build. Other keys are optional, and are analogous to their
# docker run command-line counterparts.
#
# As with docker run, options specified in the Dockerfile (e.g., CMD,
# EXPOSE, VOLUME, ENV) are respected by default - you don't need to
# specify them again in docker-compose.yml.

Use this trick to bulk delete your old repos or old forks

(Inspired by https://medium.com/@icanhazedit/clean-up-unused-github-rpositories-c2549294ee45#.3hwv4nxv5)

1. Open in a new tab all to-be-deleted github repositores (Use the mouse’s middle click or Ctrl + Click) https://github.com/username?tab=repositories

2. Use one tab https://chrome.google.com/webstore/detail/onetab/chphlpgkkbolifaimnlloiipkdnihall to shorten them to a list.

3. Save that list to some path

4. The list should be in the form of “ur_username\repo_name” per line. Use regex search (Sublime text could help). Search for ' |.*' and replace by empty.

Working with ansible-vault

---

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.
