Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Docker developers discuss changes in how ports are to be forwarded into containers
I know it looks daunting, but it's just putting ufw-style rules into your docker-compose files. There are other solutions like ufw docker automated , but they seem even more annoying to setup.

Stay safe with Docker and firewall
This is nothing new and a known issue for a very long time with docker and ufw and easily sorted by using this workaround.

Docker overrides UFW rules
Known issue for years but this and this helps.

A Docker footgun led to a vandal deleting NewsBlur's MongoDB database
Luckily it was about as hardened as regular ftp can be, but I noticed the problem when my service wasn't able to log in as the (very low) connection limit was filled by someone attempting passwords.
I've been using https://github.com/shinebayar-g/ufw-docker-automated to make docker compliant with UFW, and defining firewall rules as labels for the containers.

Should I set up my own server?
- own server costs about $5/month. I recommend using docker to deploy hbbr and hbbs. Back up the key in case you need to re-deploy. You do need to secure your Linux server, and this community-driven Github guide has some good tips to get started.

Automating the security hardening of a Linux server
I have been using the How To Secure A Linux Server guide for quite a while and wanted to learn Ansible, so I created two playbooks to automate most of the guides content. The playbooks are still a work in progress.

Connecting to docker containers rarely work, including via Caddy (non docker) reverse proxy
If it works, I will then follow the hardening guide I did before (https://github.com/imthenachoman/How-To-Secure-A-Linux-Server) and test after every step

Ask HN: How can a total beginner start with self-hosting
> In short it’s all about control, privacy, and security, in that order.
I am going to strongly urge you to consider changing that order and move *security* to the first priority. I have long run my own servers, it is much easier to setup a server with strong security foundation, than to clean up afterwards.
As a beginner, you should stick to a well known and documented Linux server distribution such as Ubuntu Server LTS or Fedora. Only install the programs you need. Do not install a windowing system on it. Do everything for the server from the command line.
Here are a few blog posts I have bookmarked over the years that I think are geared to beginners:
"My First 5 Minutes On A Server; Or, Essential Security for Linux Servers": An quick walk through of how to do basic server security manually [1]. There was a good Hacker News discussion about this article, most of the response suggests using tools to automate these types of security tasks [2], however the short tutorial will teach you a great deal, and automation mostly only makes sense when you are deploying a number of similar servers. I definitely take a more manual hands-on approach to managing my personal servers compared to the ones I professionally deploy.
"How To Secure A Linux Server": An evolving how-to guide for securing a Linux server that, hopefully, also teaches you a little about security and why it matters. [3]
Both Linode[4] and Digital Ocean[5] have created good sets of Tutorials and documentation that are generally trustworthy and kept up-to-date
Good luck and have fun
