This article will describe how to download an image from a (docker) container registry.
Intro
Remember the good ‘ol days when you could just download software by visiting a website and click “download”?
Even apt and yum repositories were just simple HTTP servers that you could just curl (or wget) from. Using the package manager was, of course, more secure and convenient — but you could always just download packages manually, if you wanted.
But have you ever tried to curl an image from a container registry, such as docker? Well friends, I have tried. And I have the scars to prove it.
It was a remarkably complex process that took me weeks to figure-out. Lucky you, this article will break it down.
Examples
Specifically, we’ll look at how to download files from two OCI registries.
Docker Hub GitHub Packages Terms
First, here’s some terminology used by OCI
OCI – Open Container Initiative blob – A “blob” in the OCI spec just means a file manifest – A “manifest” in the OCI spec means a list of files Prerequisites

This article will show reddit refugees how to easily search-for and subscribe-to to popular lemmy subreddits communities across all lemmy instances.
tl;dr use the Lemmy Community Browser https://browse.feddit.de/ Intro
Lemmy is a federated reddit alternative that started in 2019. Thanks to funding from NLNet, Open Collective, Patreon, and Librapay, the project has two full-time developers.
Unlike Reddit, all of Lemmy’s code is open-source under the AGPL.
Context
In 2008, Reddit launched an API that allowed third-party clients to use Reddit. This API has been free for 14 years.
In April 2023, Reddit announced that they would begin charging for use of their API, starting just 3-months later. This made headlines when one developer calculated that reddit’s proposed fee structure would cost them $20 million per year. As a result, most popular reddit apps including Apollo, RIF, ReddPlanet, and Sync are all shutting down in July.
In protest, hundreds thousands of subreddits are participating in a reddit blackout on June 12th.
At the time of writing, all the apps still work and protest hasn’t even started yet, but already thousands of reddit refugees have flocked to lemmy — at a rate of about 2,000 new users per day. And because . . . → Read More: Guide to Finding Lemmy Communities (Subreddits)
Whonix 14 just came out last month. I went to update, but I couldn’t figure out what version I was currently running. The documentation said to run this command, but the output didn’t make sense when I ran it on my whonix-gw TemplateVM.

So you’ve just done a fresh install of phplist, but when you attempt to load it in your browser, you get a 500 Internal Server Error. But the error log is empty! It’s possible that phplist is suppressing the errors produced by the included library random_compat. This blog post will describe this possible issue, and how to resolve it.

While I frustratingly waited to connect to the UCF Wifi after a recent change to their system, I typed up the following email complaint to the UCF DoIT Manager. If *you* have also had issues with unstable/dropped connections, slow bandwidth, latency, or the inability to connect to the UCF Wifi, I urge you to also contact the UCF Department of Information Technology via:
cst@ucf.edu = General bob.yanckello@ucf.edu = Bob Yanckello (UCF Chief Technology Officer) lou.garcia@ucf.edu = Lou Garcia (UCF Network Manager [responsible for wireless services]) chrisv@mail.ucf.edu = Chris Vakhordjian (Information Security Office) tim.larson@ucf.edu = Tim Larson (ERP Consultant) jim.ennis@ucf.edu = Jim Ennis (Enterprise Systems & Operations) andy.hulsey@ucf.edu = Andy Hulsey (Telecommunications [includes Network Services]) aaron.streimish@ucf.edu = Aaron Streimish (Project Performance & Management Office)

While I understand the benefit of encrypted wireless communications, UCF’s decision to require all student wireless clients to use WPA without preparing to sufficiently upgrade the wireless infrastructure has rendered the UCF Wifi *unusable*.
Allow me to provide a brief log of my Internet Experience this afternoon (2011-09-15).

This blog has been down for a few months while my servers were physically being moved. However, I finally purchased VPS hosting, and downtime should no longer be an issue! To celebrate, I’m going to provide my Google Alphabet as filler for this post (an interesting experiment I saw here http://www.rosshuggett.com/2010/12/my-google-alphabet.html)

The list is quite curious. I disable Web History in all my Google accounts, so these suggested words are most likely regional. It’s interesting to see what others in your area are searching for, though.
Much to my surprise, I discovered that I have 25 registered users to this web blog. I’d like to take this opportunity to point out that I’ve since created another “blog specifically to document a ~3,000 mile bicycle trip that a friend and me are embarking on this summer (2010). The website is: 2guys1biketrip.com”:http://www.2guys1biketrip.com.
Although this new blog is (obviously) _mostly_ cycling-oriented, there are some technological posts as well. For example, I plan on “plotting our trek in real-time on a Google Maps mashup using a GPS-enabled cell phone”:http://2guys1biketrip.com/wp/?page_id=59. For more info, see “my ‘GPS Tracking’ post on 2guys1bike trip”:http://2guys1biketrip.com/wp/?p=69.
Also, one of the many obstacles I’m trying to dodge for this trip is “how to charge my batteries”:http://2guys1biketrip.com/wp/?p=51. I’ve considered “pedal-power”:http://blog.makezine.com/archive/2009/06/how-to_pedal-powered_phone_charger.html and solar power.
To monitor our progress as we prepare for this epic trip, be sure to subscribe to our “2guys1biketrip RSS feed”:http://2guys1biketrip.com/wp/?feed=rss2. I’m sure there will be some solar panel hacking posts on 2guys1biketrip in the not-too-distant future.
Also, if you’ve found any of these postings to be helpful or you just feel like being exceptionally nice, please consider “contributing to our trip”:http://2guys1biketrip.com/wp/?page_id=6. Donations of any amount will be _much_ appreciated (we are both college students, . . . → Read More: My Cycling Blog
