How do you use lego?

Docker image

Effective version of lego

4.32.0

Detailed Description

Following #621, lego already builds and publishes ARMv6 builds to Github releases for use in e.g. a Raspberry Pi Zero. However, the Docker images are only built for:

lego/.goreleaser.yml

Lines 87 to 90 in 9be8cd4

	platforms:
	- linux/amd64
	- linux/arm64
	- linux/arm/v7

As such, one can't use the lego Docker image on a Raspberry Pi Zero. It should be easy enough to just add linux/arm/v6 to the goreleaser file, let me know if that is fine and I'll create an MR.

My use case is that a spare Pi Zero acts as a secondary fallback DNS server in case my primary/core one fails, and I'm using lego to request certificates for DoT/DoH support on both systems.

Hello,

it doesn't worth the cost: this is very niche, and we already have disk size issues on the CI when we create a release.

EDIT:

You can use the binary instead.

🤔 maybe we can add it inside the v5

As I will remove the old azure implementation, we will get ~500 MiB free. (more info here: #2590)
