Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

Enable persistent storage for the systemd journal log

Overview

The assumed default setting in /etc/systemd/journald.conf is Storage=auto which implies that systemd journaling will only persist the journal if the expected storage location is available. Otherwise, the journal data is stored in memory and lost between reboots. On Ubuntu 16.04, /var/log/journal does not exist by default. Create it to keep and query events from previous boots.

Considerations:

• Syslog still provides the persistant log records for Ubuntu 16.04, so enabling persistant systemd journal logging does cause a level of duplicaiton.
• There are sane defaults:

# Pass the env-vars to MYCOMMAND
eval $(egrep -v '^#' .env | xargs) MYCOMMAND
# … or ...
# Export the vars in .env into your shell:
export $(egrep -v '^#' .env | xargs)

Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.

Inbound Traffic for Swarm Management

• TCP port 2377 for cluster management & raft sync communications
• TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
• UDP port 4789 for "data plane" VXLAN overlay network traffic
• IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option

Digital Ocean recently released private networking support in their NYC2 Data center.

They also published a blog post on how to setup a new droplet with private networking. But one thing the post doesn't do is tell you how to scale your private network for many boxes. One approach is obviously to edit /etc/hosts (but this gets annoying when you add a new box). A better way is to create an internal DNS zone (via the digital ocean web interface) and have your droplets use it:

Steps

setup the internal DNS zone file

1. Login to digital ocean
2. Click "DNS" on the right hand menu
