Not all containers are whales š³
Hello internet, it's been a while. I've been working on something for a while, and today's the day I get to finally release it! Yes, I redid my website - again! But, depending on how often you talk to me, I redid my website finally. This update has been a
For me, every Monday is updates day. I run through all the entries in my Ansible hosts file and install any updates which may need running. All machines have OS updates, and the handful which run docker get their containers pulled. However, pulling containers merely updates the underlying container OS,
Both LXC and Docker are great containerization technologies, brought to you by the powers of the Linux kernel. At their core, theyāre pretty similar, but the further out you look, the differences increase massively. At their heart, theyāre both still containers - understanding the differences between the 2 takes a
Docker containers (like onions) have layers. In your Dockerfile, each new RUN, COPY or ADD line creates a new layer (so do the others, but not ones which affect the filesystem). Each layer contains only the files which changed from the previous layer, which allows layers to be shared between
Docker is a great containerization technology for running applications. It keeps multiple applications completely isolated from each other, only allowing connections exactly when you tell them to. But what if youāre on a hypervisor? You want your host OS to be as lean as possible (else it defeats the point),
GPU Passthrough has become a great way to run a Linux host, but still run games under Windows. By having 2 GPUs, 1 for the Linux host and the other for a Windows VM, you give Windows its own full GPU for games, but without having to run Windows as
NFS is a great protocol for sharing files quickly and simply over the network. Whilst itās not designed for end user use, itās great for mounting directories from remote machines, and having them be performant. NFSā lack of authentication is in a way a feature, honest. Not only does it
You should back up your data, properly! If youāre not, youāre playing a dangerous game with fate. Computers are pretty reliable, but they also go wrong, often. You should always backup your files, but backing up a containerized application isnāt quite as simple. A container is 3 things:ConfigurationVolumesNetworking The point
Recently, I started setting up a new application on my docker host. It was late in the day, and I just wanted to get something up and working to play around with. Just my luck, I was met with wonderfully cryptic error:ERROR: could not find an available, non-overlapping IPv4 address
After recently deploying a ZFS pool, I realized I had little insight into the health of my drives. I can run SMART stats now and then, but thatās not quite the same.Scrutiny Scrutiny is a tool to help you with just that. It presents a web UI which shows you
Iāve been using Traefik for a while now, and Iāve helped quite a few people with it, but I still see a lot of people scared off it. This isnāt helped by a lot of guides being incredibly verbose, and not explaining whatās going on very well. Most people I
Traefikās dashboard is a great tool to diagnose routing issues, and check services are being detected correctly, but it canāt do much more than that. It doesnāt show any metrics. Instead, it relies (arguably correctly) on external monitoring tools for metrics. Traefik supports 4 metric backends: Datadog, Prometheus, StatsD and
Clickhouse is a column oriented database engine, mostly designed for analytics. It was developed and deployed by Yandex in their analytics offering, but Plausible, my analytics provider of choice, uses it to store the analytics data, as itās more suited to this than PostgreSQL. Unfortunately, the official docker container is
Docker containers, and containers as a whole, are really just a regular program wrapped in some extra protections provided by the kernel (namely cgroups etc) to create isolation, and other interesting features. Unlike VMs, containers run closer to the host operating system, so close they use the same kernel, meaning
I only recently talked about using GoAccess as an analytics tool. Over the last couple months, Iāve been more interested in how many hits this website actually gets. GoAccess was a really simple solution which worked on log files and only captured the bits of information I really cared about:
Last year, I switched all of my hosting from arbitrarily installed packages to Docker. This made installing and configuring incredibly simple, but updating a little less defined. Whilst Docker itself is updated through the system package manager (probably), the containers themselves arenāt. Docker container versions are known as ātagsā, and
Traefik is a cloud native reverse proxy, which is basically a fancy way of saying itās a reverse proxy with some fancy features. Specifically it has fancy features around auto-discovery, and deep integration with technologies like Docker and Kubernetes.Basic concepts Traefik has four fundamental concepts: Entrypoints, routers, middleware and services.
A few days ago, I was sharing a blog post to someone on the self-hosted podcast discord, and they asked if I was self-hosting my website. Unfortunately, and rather ironically, I had to answer no. Iāve been intending to move it over to my own server for a while, so
Recently, I decided to put some analytics on my website. Would be nice to see what view number are like and what pages get the most traffic. Most people would just stick Google Analytics on and be done with. But the privacy implications off that are huge and terrible, not
