repo2docker (via) Neat tool from the Jupyter project team: run “jupyter-repo2docker https://github.com/norvig/pytudes” and it will pull a GitHub repository, create a new Docker container for it, install Jupyter and launch a Jupyter instance for you to start trying out the library. I’ve been doing this by hand using virtual environments, but using Docker for even cleaner isolation seems like a smart improvement. # 28th November 2018, 10:06 pm

dive (via) Handy command-line tool (as with so much of the Docker ecosystem it’s written in Go, which means you can download a Darwin binary directly from the GitHub releases page and run it directly on your Mac) for visually exploring the different layers of a given Docker image. # 19th November 2018, 4:41 am

Zeit 2.0, and building smaller Python Docker images

Changes are afoot at Zeit Now, my preferred hosting provider for the past year (see previous posts). They have announced Now 2.0, an intriguing new approach to providing auto-scaling immutable deployments. It’s built on top of lambdas, and comes with a whole host of new constraints: code needs to fit into a 5MB bundle for example (though it looks like this restriction will soon be relaxed a littleupdate November 19th you can now bump this up to 50MB).

Inside Docker’s “FROM scratch” (via) I’m a big fan of understanding your abstractions. Here’s a neat tutorial that dives deep into Docker’s “scratch” image which offers the smallest possible Docker image, and hence provides a great opportunity to understand what a Docker container at its most minimal does for you. # 27th November 2017, 4:33 pm

Run the First Edition of Unix (1972) with Docker (via) This is so cool... just run “docker run --rm -it bahamat/unix-1st-ed” to drop into a simulation of a PDP-11 running genuine 1972 era Unix! If you haven’t got into Docker yet, Docker for Mac is a single click install these days and works incredibly well. # 22nd November 2017, 3:36 pm

gzthermal-web (via) I built a quick web application wrapping the gzthermal gzip visualization tool and deployed it to Zeit Now wrapped up in a Docker container. Give it a URL and it shows you a PNG visualization of how gzip encodes that page. # 21st November 2017, 6:24 pm

tuxracer-web. Brilliant Docker hack from David Cooper: just run “docker run -p 8008:80 dtcooper/tuxracer-web” to get Tux Racer (the 3D game) running in your browser, on top a cunning mix of the noVNC HTML5 VNC client and icecast for sound. # 14th November 2017, 11:28 pm

Datasette: instantly create and publish an API for your SQLite databases

Docker.qcow2 never shrinks—disk space usage leak in docker for mac (via) Interesting year-long thread on disk usage by Docker for Mac, including a bunch of potential workarounds for if it swallows too much disk space. # 5th November 2017, 3:06 pm

Docker Containers on the Desktop (via) Jessie Frazelle’s classic explanation from 2015 of how she runs every desktop application on her Linux machine in its own Docker container. # 5th November 2017, 4:16 am

Running a load testing Go utility using Docker for Mac

I’m playing around with Zeit Now at the moment (see my previous entry) and decided to hit it with some traffic using Apache Bench. I got this SSL handshake error:
