Expected behavior npm app boots normally

Operating System Hypriot docker image on Pi4

[talondnb]

This seems to be because of the latest multi arch build, perhaps not using the right one for my Pi 4.

[jc21]

I don’t have a pi 4 yet, but I’ll take a look at it tomorrow

[talondnb]

Thanks. Pi 4 will be an arm7 build. Can I manually specify somehow?

[talondnb]

I've tried latest-arm7l as per tags here:

https://hub.docker.com/r/jc21/nginx-proxy-manager

This doesn't seem to work, no valid dockerfile.

[jc21]

Could you run ‘uname -a’ in you terminal and paste the output. Should tell me the arch and whether it’s 32 or 64 bit

[talondnb]

Linux gliesedocker 4.19.66-v7l+ #1253 SMP Thu Aug 15 12:02:08 BST 2019 armv7l GNU/Linux

[talondnb]

I suspect you've fixed something as i've just retried the :latest-armv7l tag and it's now working. :)

[jc21]

I thought pi4 was armv8/arm64. A quick look at Hypriot doesn’t seem to offer different versions for Pi 2/3/4

[jc21]

By the way, that latest-armv7l tag is not version NPM 2.1.0, its the previous docker manifest version

[talondnb]

Ahh I see. I’ll await updates before trying the latest tag again. 👍🏼

[jc21]

Looks like the docker buildx isn't building for the correct architectures. Still looking in to it.

[jc21]

Nope buildx was working as expected. The real problem is s6-overlay, I've mistakenly been using amd64 binaries for it across all architectures. Rookie move.

[talondnb]

Ah appreciate it, thanks for looking into this promptly.

[jc21]

All done, pull either latest, 2 or 2.1.1 docker image tag. Tested with arm64 and rpi3 w/ hypriot

[talondnb]

Working fine again, thank you!

Hi,

I'm geting a smilar error with rpi4 64 bit (using the official OS 32 bit).

uname -a Linux raspberrypi 4.19.118-v7l+ #1311 SMP Mon Apr 27 14:26:42 BST 2020 armv7l GNU/Linux

This are the images that I'm using: app: image: jc21/nginx-proxy-manager:latest

db: image: jc21/mariadb-aria:latest

[robertolanuti]

Update: I'm able to run succesfully it by using the following db image: db: image: yobasystems/alpine-mariadb:latest
