Notes on using Docker on ARM Macs (November 2021)

Docker for Mac

On M1 machines, Docker for Mac is running a lightweight linux ARM VM, then running containers within that, so containers are essentially running natively. Don't be fooled by the fact the UI or binary CLI tools (e.g. docker) might require Rosetta.

Within that VM is an emulation layer called QEmu. This can be used by docker to run Intel containers. This does not use Rosetta at all, and has a roughly 5-6X performance penalty. (If you just upgraded your CPU this may result in a similar performance to your old machine!)

Pulling and running with Docker

Many images in public registries are multi-architecture. For instance at the time of writing on Docker Hub the php:8.0-cli image has the following digests:

/* So how does this work?
I'm using ANSI escape sequences to control the behavior of the terminal while
cat is outputting the text. I deliberately place these control sequences inside
comments so the C++ compiler doesn't try to treat them as code.*/

/*The commands in the fake code comment move the cursor to the left edge and
clear out the line, allowing the fake code to take the place of the real code.
And this explanation uses similar commands to wipe itself out too. */
