# Note: these steps assume installation with Homebrew.
# Initialize a new database, adding a .new suffix to the directory that Homebrew recommends.
initdb /usr/local/var/postgres.new -E utf8
# Run the upgrade script, providing the correct paths for the various flags.

Quick and dirty DDNS using Bash and Cloudflare (API v4 compatible)
#!/usr/bin/env bash
# Step 1: Fill in EMAIL, TOKEN, DOMAIN and SUBDOMAIN. Your API token is here: https://dash.cloudflare.com/profile/api-tokens
# Make sure the token is the Global token, or has these permissions: #zone:read, #dns_record:read, #dns_records:edit
# If you want to set the root domain instead of a subdomain, set SUBDOMAIN to "@"
# Step 2: Create an A record on Cloudflare with the subdomain you chose
# Step 3: Run "./ddns.sh -l" to get the zone_id and rec_id of the record you created.
# Fill in ZONE_ID and REC_ID below
# This step is optional, but will save you 2 requests every time you run this script
# Step 4: Run "./ddns.sh". It should tell you that record was updated or that it didn't need updating.

How to use?

  1. Put the cfupdater files to /usr/local/bin
  • If you are using IPv4 for A record, append -v4 to cfupdater in the following systemd service unit.
