Learning Containers From The Bottom Up
https://iximiuz.com/en/posts/container-learning-path/, posted 2021 by peter in deployment development learning linux toread virtualization
This article is not an attempt to explain containers in one go. Instead, it's a front-page for my multi-year study of the domain. It outlines the said learning path and then walks you through it, pointing to more in-depth write-ups on this same blog.
Mastering containers is no simple task, so take your time, and don't skip the hands-on parts!

Firecracker: start a VM in less than a second
https://jvns.ca/blog/2021/01/23/firecracker--start-a-vm-in-less-than-a-second/, posted 2021 by peter in deployment development howto reference virtualization
But it turns out that Firecracker is relatively straightforward to use (or at least as straightforward as anything else that's for running VMs), the documentation and examples are pretty clear, you definitely don't need to be a cloud provider to use it, and as advertised, it starts VMs really fast!
So I wanted to write about using Firecracker from a more DIY "I just want to run some VMs" perspective.
I'll start out by talking about what I'm using it for, and then I'll explain a few things I learned about it along the way.

Setting up a signed private apt repository with HTTPS access
tomthegreat.com/2018/02/21/setting-up-a-signed-private-apt-repository-with-lan-access/, posted 2019 by peter in deployment howto linux security toread
This is a guide on setting up private apt repository that is accessible over a local network via HTTPS and is signed to avoid having to use –allow-unauthenticated to install packages.
...
For my use case I have two distributions of packages, they are production and test distributions. The packages in each distribution varies based on what I have approved to be used in a live/production environment versus a test environment. This is so that I can separate out packages that I am using for normal everyday use versus ones I am currently testing with and not ready to go live with. If you are only using one distribution modify the instructions accordingly.

Digested: The Secrets of Docker Secrets
digested.blogspot.com/2019/11/the-secrets-of-docker-secrets.html, posted 2019 by peter in automation continuousdelivery deployment docker howto toread
Most web apps need login information of some kind, and it is a bad idea to put them in your source code where it gets saved to a git repository that everyone can see. Usually these are handled by environment variables, but Docker has come up with what they call Docker secrets. The idea is deceptively simple in retrospect. While you figure it out it is arcane and difficult to parse what is going on.

Docker 1.12: Now with Built-in Orchestration! | Docker Blog
https://blog.docker.com/2016/06/docker-1-12-built-in-orchestration/, posted 2016 by peter in continuousdelivery deployment docker opensource
Starting with Docker 1.12, we have added features to the core Docker Engine to make multi-host and multi-container orchestration easy.
We’ve added new API objects, like Service and Node, that will let you use the Docker API to deploy and manage apps on a group of Docker Engines called a swarm. With Docker 1.12, the best way to orchestrate Docker is Docker!

How to Deploy Software
https://zachholman.com/posts/deploying-software, posted 2016 by peter in automation continuousdelivery deployment opinion
This is a long — sorry not sorry! — written piece specifically about the high-level aspects of deployment: collaboration, safety, and pace. There's plenty to be said for the low-level aspects as well, but those are harder to generalize across languages and, to be honest, a lot closer to being solved than the high-level process aspects. I love talking about how teams work together, and deployment is one of the most critical parts of working with other people. I think it's worth your time to evaluate how your team is faring, from time to time.

Dockerfiles considered harmful
blog.wercker.com/2015/07/28/Dockerfiles-considered-harmful.html, posted 2015 by peter in deployment docker opinion security
There are some obvious issues with running third-party Dockerfiles. Like most of the Docker ecosystem, Dockerfiles were designed for personal use by an individual with root access. Once you start distributing them, however, you’re essentially giving root to a stranger. This blog post is about why you shouldn’t even be using Dockerfiles for your own projects.

Serf is a tool for cluster membership, failure detection, and orchestration that is decentralized, fault-tolerant and highly available. Serf runs on every major platform: Linux, Mac OS X, and Windows. It is extremely lightweight: it uses 5 to 10 MB of resident memory and primarily communicates using infrequent UDP messages.
