Download droplet snapshot or backup from Digital Ocean

Download droplet snapshot or backup from Digital Ocean

Problem

Digital Ocean does not allow you to download backups or shanpshots of the droplet. This may be a problem if you want to migrate from Digital Ocean to somewhere else.

Solution

  1. Boot into Recovery Console (choose Boot from Recovery ISO option) for the source droplet. If you need specific backup or snapshot, you would need to restore it either into source droplet or create a new droplet out of it.

Oneliner that creates and installs a conventional commit enforcement script for git. Run this oneliner in your git repo root.
printf '#!/bin/sh\n
# Get the commit message
commit_message=$(cat "$1")\n
# Regular expression pattern for conventional commits
pattern='\''^(feat|fix|docs|style|refactor|test|chore)(\([a-z0-9-]+\))?!?: [^\s].{0,100}$'\''\n
# Check if the commit message matches the pattern
if echo "$commit_message" | grep -qE "$pattern"; then
\techo "Commit message is compliant with conventional commits."
else
\techo "Commit message is not compliant with conventional commits. See https://www.conventionalcommits.org/en/v1.0.0/#summary"; exit 1
