Introduction to heredocs in Dockerfiles (via) This is a fantastic upgrade to Dockerfile syntax, enabled by BuildKit and a new frontend for executing the Dockerfile that can be specified with a #syntax= directive. I often like to create a standalone Dockerfile that works without needing other files from a directory, so being able to use <<EOF syntax to populate configure files from inline blocks of code is really handy. # 22nd November 2021, 5:01 pm
Weeknotes: Apache proxies in Docker containers, refactoring Datasette
Updates to six major projects this week, plus finally some concrete progress towards Datasette 1.0.
[... 1630 words]aws-lambda-adapter. AWS Lambda added support for Docker containers last year, but with a very weird shape: you can run anything on Lambda that fits in a Docker container, but unlike Google Cloud Run your application doesn’t get to speak HTTP: it needs to run code that listens for proprietary AWS lambda events instead. The obvious way to fix this is to run some kind of custom proxy inside the container which turns AWS runtime events into HTTP calls to a regular web application. Serverlessish and re:Web are two open source projects that implemented this, and now AWS have their own implementation of that pattern, written in Rust. # 28th October 2021, 5:04 am
Weeknotes: Learning Kubernetes, learning Web Components
I’ve been mainly climbing the learning curve for Kubernetes and Web Components this week. I also released Datasette 0.59.1 with Python 3.10 compatibility and an updated Docker image.
[... 1101 words]We never shipped a great commercial product. The reason for that is we didn’t focus. We tried to do a little bit of everything. It’s hard enough to maintain the growth of your developer community and build one great commercial product, let alone three or four, and it is impossible to do both, but that’s what we tried to do and we spent an enormous amount of money doing it.

GitHub’s Engineering Team has moved to Codespaces. My absolute dream development environment is one where I can spin up a new, working development environment in seconds—to try something new on a branch, or because I broke something and don’t want to spend time figuring out how to fix it. This article from GitHub explains how they got there: from a half-day setup to a 45 minute bootstrap in a codespace, then to five minutes through shallow cloning and a nightly pre-built Docker image and finally to 10 seconds be setting up “pools of codespaces, fully cloned and bootstrapped, waiting to be connected with a developer who wants to get to work”. # 11th August 2021, 4:53 pm
Best Practices Around Production Ready Web Apps with Docker Compose (via) I asked on Twitter for some tips on Docker Compose and was pointed to this article by Nick Janetakis, which has a whole host of useful tips and patterns I hadn’t encountered before. # 12th June 2021, 2:36 am
Weeknotes: Docker architectures, sqlite-utils 3.7, nearly there with Datasette 0.57
This week I learned a whole bunch about using Docker to emulate different architectures, released sqlite-utils 3.7 and made a ton of progress towards the almost-ready-to-ship Datasette 0.57.
[... 1081 words]logpaste (via) Useful example of how to use the Litestream SQLite replication tool in a Dockerized application: S3 credentials are passed to the container on startup, it then attempts to restore the SQLite database from S3 and starts a Litestream process in the same container to periodically synchronize changes back up to the S3 bucket. # 17th March 2021, 3:48 pm
