Migrate Maven packages from Sonatype Nexus to GitHub Packages

This gist describes the process we've used to migrate our Maven package repository from Sonatype Nexus to GitHub Packages. The same process could be used for migrating any Maven package repo that is in the standard layout.

We created a special repository on GitHub to hold all of our Maven packages. You might decide to migrate packages to different repositories, in which case invoke the script multiple times.

The script uses find to look for all of the folders containing poms and upload them. You specify the folder

Docker(-compose) with shorewall

The shorewall documentation explains in http://shorewall.org/Docker.html how to configure shorewall for use with docker. The problem with the configuration is that it only allows connections from the host to the main bridge docker0. Connections to other networks on dynamically created bridges, with names starting by default with br-, is blocked. Instead of the recommended contents of /etc/shorewall/interfaces, use wild-card interface names as follows:

#ZONE	INTERFACE	OPTIONS
#dock	docker0		bridge     # disabled default recommendation
dock 	docker0		physical=docker+,routeback=1
dock 	br		physical=br-+,routeback=1

Docker on BTRFS is very buggy and can result in a fully-unusable system, in that it will completely butcher the underlying BTRFS filesystem in such a way that it uses far more disk space than it needs and can get into a state where it cannot even delete any image, requiring one to take drastic actions up to and including reformatting the entire affected BTRFS root file system.

According to the official Docker documentation:

btrfs requires a dedicated block storage device such as a physical disk. This block device must be formatted for Btrfs and mounted into /var/lib/docker/.

In my experience, you will still run into issues even if you use a dedicated partition. No, it seems it requires a standalone

Running docker-compose as a systemd service

Files

File	Purpose
`/etc/compose/docker-compose.yml`	Compose file describing what to deploy
`/etc/systemd/system/docker-compose-reload.service`	Executing unit to trigger reload on `docker-compose.service`
`/etc/systemd/system/docker-compose-reload.timer`	Timer unit to plan the reloads
`/etc/systemd/system/docker-compose.service`	Service unit to start and manage docker compose

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
