for ubuntu, to set up a dynamic dns service that tells you what the external ip of some machine is

• npm install dat lil-pids run-every add-to-systemd -g
• mkdir ipdat; cd ipdat; dat create; cd ..;
• edit file services with this:

cd ipdat && dat sync
cd ipdat && run-every 3600 curl ipinfo.io/ip > ip.txt

# This script should be located on each Jenkins slave, and the jenkins user should have permission to run it with sudo

# Attempts to cleanly stop and remove all containers, volumes and images.
docker ps -q | xargs --no-run-if-empty docker stop
docker ps -q -a | xargs --no-run-if-empty docker rm --force --volumes
docker volume ls -q | xargs --no-run-if-empty docker volume rm
docker images -a -q | xargs --no-run-if-empty docker rmi -f

# Stops the docker service, unmounts all docker-related mounts, removes the entire docker directory, and starts docker again.

About

This is a collection of snippets, not a comprehensive guide. I suggest you start with Operational PGP.

Here is an incomplete list of things that are different from other approaches:

• I don't use keyservers. Ever.
• Yes, I use Gmail instead of some bespoke hipster freedom service
