Instructions for exporting/importing (backup/restore) GPG keys

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

Example of using bundler/inline

I came across 'bundler/inline' in Bundler pull request 3440, which I'd found from Rails pull request 20429. This now has a little snippet on the What's new page of the Bundler site.

This little example demonstrates how I might use it to create a single file using minitest.

I've just noticed that this script was working for me because I already had minitest installed as a system gem. If I uninstall the gem then the script fails because it can't find minitest. The source code documents an option to install gems if they don't exist (gemfile(true) do) but that doesn't seem to work for me. I see the following error:

Fetching gem metadata from https://rubygems.org/...
Fetching version metadata from https://rubygems.org/..

Using a Let's Encrypt SSL certificate to serve a Rails app on Heroku

Intro

This is very similar to Collective Idea's blog post, "[Let's Encrypt with a Rails app on Heroku][collective-idea-blog-post]". I ran through the process a couple of times to try to understand how the various parts fit together.

Create a new Rails app

NOTE. I'm skipping Active Record to make the deployment to Heroku slightly easier.
