# Description:
#   Update the DNS A Record with your public IP address for the one.com host.
#
# Recommendation:
#  - Create a separate user that can only access the DNS records.
#  - Create a cron tab to run this script every 30 minutes:
#       crontab -e
#       */30 * * * * ~/Scripts/update-dns-one.com.sh  >/dev/null 2&>1
#  - To get the Sub Domain Id you will have to manually update the domain and record the network traffic using your browser

# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object 
# and the abbreviated object name of the most recent commit.
git describe

# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

UFW

I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.
